East Wareham

Prepared by Carolyn DeMoranville

Unlike last year, December 2016 was just a bit above to average in temperature and dry.  The temperature averaged 35.2 degrees, 0.8 degrees per day above the 30-year average (compared to almost 14 degrees above average in 2015).  Maximum temperature was 59.0 degrees on the 1st; a minimum temperature of 6.8 degrees was recorded on the 16th.  Daytime high temperatures averaged 43.5 degrees, 0.8 degrees above the norm.  Evening temperatures averaged 26.8 degrees, 0.6 degrees above the norm.

Precipitation totaled 3.60 inches, 0.93 inches below normal.  We recorded 7 days with more than 0.1 inches of rain. The largest rainfall was 1.08 inches from the 17th to the 18th.  Total rainfall for 2016 was 41.24 inches, 8.8 inches below average for East Wareham and 2.5 inches less than the total rainfall for 2015, another dry year.  There was one day with measurable snow this month - about 4 inches fell on the 17th but washed away by afternoon as the precipitation turned to rain.  Average snowfall for the month of December in East Wareham is 6.98 inches.

Sunshine for the month (recorded at the Blue Hills Observatory) was above average, totaling 52% of possible, 4 points above the norm.  There were six days with 90% or greater sunshine hours and 5 days with no sunshine at all. 

Year End Summary 2016

The year 2016 had well-below average rainfall, was even drier than 2015 and the driest year since 2004.  In 2015, the extreme winter snowfall helped to mitigate drought conditions, but in 2016 there was only about half the amount of snowfall (7.5 inches above average vs. 50.8 inches above average in 2015).  As a result, drought conditions became apparent by June 2016 as rainfall began to fall below average once again.  For the year, rainfall in East Wareham was 8.8 inches below average and the two year period of 2015-2016 saw a total deficit of 15.1 inches.  The last time we saw large rainfall deficits in consecutive years was the major drought of 1965-1966; 1965 was 19.4 inches below the norm and 1966 was 10.3 inches below, for a two year deficit of 29.7 inches.

This was another very warm year with 11 of the 12 months having average daily temperature above the norm.  Only April was below normal in temperature.  The average temperature for the year was 52.08 degrees, 2 degrees above the 30-year average, making this the 3rd warmest year in East Wareham since records began in 1926.  We had our 7th above average July in a row and August set a new average daily temperature record for East Wareham at 74.5 degrees, surpassing the previous record of 73.7 held in 1937 and 2015. 

Annual sunshine was 57% of possible at the Blue Hills Observatory, 2% above the norm.

Winter was warm and wet, spring was warm and about average in precipitation, summer and fall were warm, sunny, and very dry, and we ended the year with dry conditions in December. Temperatures for the year averaged 52.08 degrees, 2 degrees above the 30-year average in East Wareham.  The average monthly temperature was above normal 11 out of 12 months.  The maximum temperature for the year of 95 degrees was recorded on July 23rd.  The minimum temperature of -8.5 degrees was recorded on February 14th.  We had much less snow than in 2015; the total snowfall for 2016 was 42 inches, 7.5 inches above the yearly average.

The official winter in East Wareham (Dec. 2015 - Feb. 2016) was very warm and wet with snowfall and sunshine both a bit above average. Temperature for the 3 months averaged 37.3 degrees, 8.1 degrees above normal and 8.6 degrees warmer than the previous winter.  Snowfall for the winter of 2015- 2016 in East Wareham was 30.6 inches, mostly in January and February, 3.5 inches above normal.  The official spring (March-May) had above average temperatures - 47.4 degrees, 2.0 degrees above average.  Snowfall for the period totaled 7.8 inches (all in April), 1.6 inches above average.  Precipitation was 0.77 inches above normal at 12.94 inches. The official summer (June, July and August) saw the true drought begin with very warm, dry, and sunny conditions.  The average temperature was 71.7 degrees, 2.5 degrees above the 30-year average for the 3-month period. All three months were above average in temperature, with August surpassing the 1937/2015 record.  Total rainfall for the summer was 4.54 inches, 6.42 inches below the norm.  The official fall season (Sept. – Nov.) was warm, dry, and well above average for sunshine.

By the year’s end, precipitation totaled 41.24 inches, 8.8 inches below normal, with October being the wettest month with 6.03 inches of rainfall.  The driest month was June with only 1.03 inches of rain.  February gave us the greatest snowfall in 2016 with 16.0 inches, with a total of 42 for the year.  The highest temperature for the year was recorded in July. 

Sunshine hours for the year of 2016 totaled 57% of the possible.  There were nine months with high sunshine hours and two months with low sunshine hours; March was right on the norm.  Possible sunshine for the year was just 2 points above normal.

Overall, we started 2016 in a rainfall deficit from 2015 but with average conditions until June when drought conditions returned. The year as a whole was warm (11 of 12 months above average and the third warmest annual average temperature in East Wareham records), with summer quite hot and a new record average temperature for August.  The year ended with continued dry conditions but more seasonal temperatures.

November was just above average in temperature, very dry, and very sunny.  The temperature averaged 44.9 degrees, 0.7 degrees above normal.  Maximum temperature was 66.2 degrees on the 2nd; a minimum temperature of 26.6 degrees was recorded on the 28th and the 29th.  Daytime high temperatures averaged 53.9 degrees, 1.5 degrees above the norm.  Nighttime temperatures averaged 35.9 degrees, 0.6 degrees above the norm.  November 2016 average temperature was much cooler than that in November 2015 but still above the 30-year average for the month.  So far 2106 has had 10 of 11 months with above average temperature.

Precipitation totaled 2.26 inches, 2.42 inches below normal.  Measurable precipitation of 0.10 inches or more was recorded on 4 days.  More than half of the total for the month (1.21 inches) came on the 29th.  Year-to-date rainfall for 2016 is 37.64 inches, 7.87 inches below the year-to-date average for East Wareham at this time of year.  This deficit is slightly less than at this time in 2015.  Since June, we are at only 68% of normal precipitation.  There was no snowfall recorded for the month of November in East Wareham.  The average snowfall for November in East Wareham is 1.0 inch.

Sunshine, recorded at the Blue Hills Observatory, totaled 53% of the possible, 6 point above average.  There were 10 days with 90% or more sunshine, and 8 days with near zero. 

Official Fall Season

The official fall season, Sept. – Nov. 2016, was warm, dry, and above average for sunshine.  Temperatures averaged 55.4 degrees, 2.1 degrees above normal but not as warm as fall 2015.  A maximum temperature of 90.5 degrees was recorded on the 9th of September and a minimum temperature of 26.6 degrees was recorded on the 28th and 29th of November.  Rainfall totaled 11.84 inches, 1.35 inches below normal.  Average snowfall for the fall season for East Wareham is 1.0 inch; we received no snow this season.  Sunshine was 54% of the possible, 2 points above the norm for the fall season.

October

October was warm and a bit sunnier than average.  Rainfall was above average for the first month since May, very welcome indeed if not yet enough to entirely break the drought.  The temperature averaged 54.8 degrees, 2.1 degrees per day above average, warmer than 2015.  Maximum temperature of 77.0 degrees was recorded on the 19th; a minimum temperature of 32.0 degrees was recorded on the 27th, the first freeze of the season.  Daytime high temperatures averaged 63.7 degrees, 1.9 degrees above the norm.  Evening low temperatures averaged 46.1 degrees, 2.4 degrees above the norm. This is the 7th year in a row of warmer than average daytime highs in October, 6 of the 7 years also had a nighttime low above the 30-year average.  So far in 2016, all months, with the exception of April, have had above average temperatures.

Sunshine totaled 58% of the possible sunshine hours, 3 points above the norm and similar to 2015.  The Blue Hills observatory had 12 days that were mostly clear (90% of possible) and 6 days with no sunshine.  There were 9 days with fog in East Wareham this month.  Year-to-date sunshine is running well above the norm (more than 200 hours above). 

Precipitation totaled 6.03 inches, 1.89 inches above the 30-year average.  The largest rainfall came on the 8-9th, 2.18 inches.  Measurable rain was recorded on 8 days, 7 days of which had rainfall of 0.10 inches or greater.  This was only the 3rd month with above average rainfall this year.  Year-to-date rainfall for 2016 is 35.38 inches; 5.45 inches below average for East Wareham.  Notably, our rainfall deficit for the year is less than it was this time last year.  The big difference is that we started 2015 with high water tables after the 2014-2015 snows but started 2016 already in a deficit since 2015 came in at more than 6 inches below the norm.

NOTE: Beginning in 2016, the temperature and rainfall data are compared to the 30 year average for the period 1981 to 2010.

September was warm with below average sunshine and continued dry conditions for most of the month.  The temperature averaged 66.5°, 3.4 degrees per day above normal. Maximum temperature was 90.5° on the 9th; a minimum temperature of 41.0° was recorded on the 26th.  Daytime high temperatures averaged 74.8°, which is 2.8 degrees above the norm.  Evening temperatures averaged 58.9°, 4.3 degrees above the norm.  There were 8 days with a maximum temperature above 80°.  So far in 2016, all months, with the exception of April, have had above average temperatures.

Sunshine totaled 51% of the possible sunshine hours, 8 points below the norm.  We recorded 13 sunny days in East Wareham and 4 days with morning fog.  The Blue Hills Observatory (official site for sunshine hour data), recorded 12 sunny days and 10 days with fog. 

Precipitation totaled 3.55 inches, 0.79 inches below normal, making this the fourth consecutive month of below average rain.  We had measurable rain of 0.10 inches or greater on 7 days, and 3 days with spotty showers and drizzle with less than 0.10 inches recorded.  The largest 24-hour rainfall was 1.58 inches on the 19th (recorded on the 20th), accounting for 45% of the month's total.  

Year-to-date rainfall for 2016 is 29.35 inches, 7.34 inches below average for East Wareham but not as far below normal as 2015 at this time.  However, we came into 2015 with high water tables after the snowy 2014-2015 winter.  This year, after a low snowfall winter and four months of below average precipitation, the area remains in serious drought condition.

NOTE: Beginning in July 2016, the temperature and rainfall data will be compared to the 30 year average for the period 1981 to 2010.  The reports for January to June 2016 have been modified to reflect this new convention for the entire year, since often we refer to 'year to date' information.  The data that have been corrected in those reports is highlighted in bold.  It is worthy of note that compared to the 30 year averages from 1961 to 1990 (previous comparator), the average daily temperature was warmer in every month in the 1981-2010 data set compared to that in the older one.

August was a record warm, very dry and very sunny month.  The temperature averaged 74.5 degrees, 4.0 degrees above normal, beating the old record of 73.7° from 2015 and 1937. There were 4 days of 90 or above temperature with another 11 days of 85-89°.  The maximum temperature of 92.3 was recorded on the 14th.  The minimum temperature of 55.4 degrees was recorded on the 23rd.  Daytime high temperatures averaged 84.7 degrees, 5.9 degrees above the norm.  Evening temperatures averaged 65.2 degrees, 3.5 degrees above the norm.  There were 7 nights with temperatures of 70 or above and and only 6 nights with temperatures below 60.

Sunshine totaled 71% of the possible sunshine hours, which is 13 points above the norm.  There were 14 days with 90% or greater of possible sunshine, and only one day with no sunshine.

Precipitation totaled 1.59 inches, 2.28 inches below normal.  We had measurable precipitation on 6 days, with 5 of those have more than 0.1 inch. More than a third of the rain (0.61") was recorded on the 1st. Year-to-date, 2016 has received 32.35 inches of rain, 6.55 inches below the yearly average for East Wareham.   Most of that deficit has occurred in the last 3 months.

Official Summer Season 

The official summer (June, July and August) was very warm, dry, and sunny.  The average temperature was 71.7 degrees, 2.5 degrees above the 30-year average for the 3-month period. All three months were above average in temperature, August setting a new record.  Total rainfall for the season was 4.54 inches, 6.42 inches below the normal precipitation for this time of year; with all three months seeing below normal rainfall.   Sunshine hours totaled 923 hours; this is 180 hours above the average for the three months, all of which were above normal.  We had a maximum temperature of 95 degrees recorded on July 23rd and a minimum temperature of 51.8 degrees recorded on June 9th.  There were 8 days of 90° or more, the last occurring on August 29th.  We had no official heat wave this season. 

Crop Forecast 

New England Agricultural Statistics Service released the United States forecast for the 2016 Cranberry crop.  Overall production is predicted to be 8.59 million barrels, up slightly from 2015.  With the exception of Wisconsin, all of the major growing regions anticipate lower crops than in 2015.  The forecast for Massachusetts is for 2.07 million barrels.

NOTE: Beginning this month, the temperature and rainfall data will be compared to the 30 year average for the period 1981 to 2010.  The reports for January to June 2016 have been modified to reflect this new convention for the entire year, since often we refer to 'year to date' information.  The data that have been corrected in those reports is highlighted in bold.  It is worthy of note that compared to the 30 year averages from 1961 to 1990 (previous comparator), the average daily temperature was warmer in every month in the 1981-2010 data set compared to that in the older one.

July 2016 was warm, dry, and sunny.  With 4 days of 90+ temperature, July’s temperature was 2.4 degrees above average and 1.1 degrees warmer than July 2015.  The 90+ days were not consecutive, so there was no heat wave.  An additional 11 days had maximum temperatures from 85 to 89°.  As was reported for Boston, this is the 7th July in a row with above average temperature.  Maximum temperature was 95 degrees, recorded on the 23rd, and a minimum temperature of 55.4 degrees was recorded on the 20th.  Daytime high temperatures averaged 83.2 degrees, 3.2 degrees above the norm.  Evening temperatures averaged 65.4 degrees, 2.5 degrees above the norm.  For 2016, 6 of the 7 months have seen above average temperature.

Sunshine at the Blue Hills Observatory totaled 66% of the possible sunshine hours, 9 points above average, making this the sunniest July since 1993. We had 12 days with 90% or greater of possible sunshine, while on 4 days was there less than 10% sunshine.  We had fog in East Wareham on 4 days.

We recorded 1.92 inches of rainfall, which is 1.4 inches below the average for July.  A total of 1.32 inches of the rain came over the July 4th weekend, while the second half of the month saw only about a third of an inch.  Rainfall was recorded on 5 days, with only 2 having over 0.10 inch.   Year-to-date rainfall for 2016 is 28.48 inches, 4.27 inches below the average for East Wareham.  While this deficit is less than that at this time in 2015, the period of June and July this year has seen only 42% of the normal rainfall.  There was 1 thunderstorm recorded this month.

NOTE: Beginning in July of this year, we began to use the 30 year average for the period 1981 to 2010 as the comparator for the temperature and rainfall data.  The reports for January to June 2016 have been modified to reflect this new convention for the entire year, since often we refer to 'year to date' information.  The data that have been corrected are in bold.

June was an extremely sunny month with above average temperature and well below average rainfall.  The month was also characterized by noticeably low dew points.  The mean temperature for the month was 66.7 degrees, 1.1 degrees above average.  Maximum temperature was 85.1 degrees on the 30th; a minimum temperature of 51.8 degrees was recorded on the 9th.  Daytime high temperatures averaged 76.8 degrees, 2.8 degrees above the norm.  Evening temperatures averaged 57.7 degrees, 1 degree above the norm.  

Sunshine was well above average with 69% of the possible sunshine recorded.  This is 14 percentage points above the average for June sunshine, the 7th sunniest June on record at the Blue Hills Observatory.  Ten days were rated as sunny (90% or greater of possible) with only 6 being cloudy.  

Precipitation totaled 1.03 inches, which is 2.74 inches below the 30-year average.  We had measurable precipitation on only 5 days, with 2 of those days having measurable precipitation of 0.10 inches or greater.  The largest 24-hour rainfall was 0.46 inches on the 21st.  Year-to-date rainfall for 2016 now stands at 22.29 inches, 2.87 inches below average. The high sunshine along with above average temperature, low dew points, and lack of rain led to very dry conditions - browning of plants was common.

The first half of 2016 has been warm and dry.  Temperatures have averaged 1.78 degrees above normal for the first half of the year; all months but April were above average (April was right on the norm).  Rainfall was 2.7 inches below normal for this 6-month period.  This is the third year in a row with below normal rainfall for the first 6 months.  Sunshine has been above average for the period with only May below average.

May weather was about average in temperature but with less sunshine than is normal.  Rainfall was above the 30-year average but mainly due to a single event at the end of the month.  The temperatures for May averaged 56.2 degrees, 0.4 degrees above the 30-year average.  The maximum temperature was 85.1 degrees on the 26th and a minimum temperature of 34.7 degrees was recorded on the 10th.  Daytime high temperatures averaged 65.5 degrees, 0.6 degrees above the norm.  Evening temperatures averaged 47.9 degrees, 0.9 degrees above the norm.

Based on data from the Blue Hills Observatory, sunshine totaled 47% of the possible sunshine hours, 5 percentage points below the norm.  There were 6 days with 90% or better sunshine (similar to the last 2 years) but 9 days with no sunshine at all (there was only 1 last year but 12 in 2014).  There were 5 days with fog in East Wareham. 

Precipitation totaled 5.07 inch, 1.36 inches above the average rainfall for May in East Wareham.  This is the first wet May in the last three years but the large total for 2016 is skewed by a large event on the 30th.  There were 10 days with measurable precipitation, 8 with more than 0.1 inch. The largest 24-hour rainfall, accounting for almost 40% of the monthly total, was 1.94 inches on the 30th.  Our total year-to-date rainfall is 21.26 inches, only 0.13 inches below the average in East Wareham.

Official Spring Season

The official spring (March-May) had above average temperatures - 47.4 degrees, 1.1 degrees above average - primarily due to a warm March.  Snowfall for the period totaled 7.8 inches (all in April), 1.6 inches above average.  Precipitation was 0.77 inches below normal at 12.94 inches.  Sunshine for the spring was 634 hours, 51% of possible hours for the three month period and 2% above the norm.  Sunshine during March was right on average, April was above the norm, and May was well below average.

April started out warm but turned quite cold from the 3rd to the 6th.  In fact the night of the 5-6th was the coldest since February after 7.8 inches of snow on the 4th.  A mild spell mid-month was followed by more cool temperatures.  April, normally a wet, cloudy month, was very sunny in 2016, with only 7 days of measurable precipitation.

Overall, the temperature averaged 44.9 degrees, 1.2° below the 30-year average.  The maximum temperature was 75.2 degrees on the 22nd and a minimum temperature of 16.7 degrees was recorded on the 6th.  Daytime high temperatures averaged 53.0 degrees, 1.9 degrees below the norm.  Evening low temperatures averaged 36.1 degrees, 0.7 degrees below the norm. 

Sunshine, recorded at the Blue Hills Observatory, totaled 60% of the possible sunshine hours, 11 points above the norm.  There were 11 days with 90% or better sunshine and only 5 days with virtually no sunshine.  We experienced heavy fog only on 2 days during the month of April.

Precipitation totaled 4.56 inches, which is 0.05 inches above normal.  We had measurable precipitation on 7 days; 6 of those had 0.10 inches or greater rainfall.  The largest 24-hour rainfall was 1.86 inches on the 3rd.  Year-to-date rainfall for 2016 stands at 16.19 inches; this is 0.96 inches above last year’s total at this time but 1.49 inches below the normal average for this time of year.  We did have 1 thunderstorm on the 7th.

We had 7.8 inches snowfall in April, 7 inches above average for the month. This brings the 2015 – 2016 season to a total of 38.4 inches of snow, just slightly above average.  This is 47.6 inches less then the 2014-2015 season!

January, while not as warm as December, was another above average temperature month.  Temperatures at the beginning and end of the month were particularly warm with more seasonable weather mid-month.  We had above-average temperatures and sunshine with below average rainfall and above average snowfall.  The average temperature was 32.1 degrees, 3.0 degrees above normal. The maximum temperature was 56.3 degrees on January 10th.  A minimum temperature of 8.6 degrees was recorded on the 6th.  Daytime high temperatures averaged 40.5 degrees, 2.8 degrees above the norm.  Evening temperatures averaged 23.8 degrees, 3.5 degrees above the norm.  Daytime high temperatures were 50 degrees or greater on 3 days.  Evening temperatures were 32 degrees or below for all but 5 nights.  There was 1 night with temperatures in the single digits.

The winter continues to be mild with the average temperature for the two winter months to date of 38.9 degrees, 7.1 degrees greater than the 30-year average and the warmest December/January average in our records (since 1928).

Precipitation totaled 3.42 inches.  This is 0.65 inches below normal.  We had measurable precipitation on 5 days; 3 of those days had less than 0.10 inches.  The largest 24-hour rainfall was 1.41 inches from the 17th to the 18th.  We had measurable snowfall of 0.1 inches or greater on 3 days, totaling 14.2 inches for the month, 3.4 inches above average. The largest snowfall came during a 24-hour blizzard, on the 23rd and 24th of January, with 8.0 inches of snow, high winds and considerable drifting.   So far this season we have recorded a total of 14.6 inches of snow.

Sunshine totaled 53% of the possible sunshine hours, 7 points above normal.  There were 6 days with no sunshine and 8 days with 90% or better sunshine.  Total sunshine for January 2016 was 7 points greater than that recorded in January 2015.
