After a wet and cool June, then a hot and somewhat dry July we saw another dry month in August with normal temperatures.
Lets begin with the temperatures. Although Boston came close to 90 degrees on a few occasions it never reached 90 for the month and that was the first time since 2008. High readings of 89 were recorded on the 21st and 22nd and although 90 degrees was reached in some of the surrounding suburbs, officially in Boston it was not. Overall, 13 days were below average, 14 above average and the remaining three average. And, the month on average turned to be, well average, with an average temperature of 72.1 degrees. The average high was 79.8 and overnight lows at 64.5. Highest reading was 89 on the two days previously mentioned and a low of 59 on the 6th. The longest stretch of consecutive days of above normal readings was from the 19th through the 23rd when it was about 4 degrees over normal during the 5 day period.
Rainfall was only 1.84 inches for the month and was -1.51 inches below average. Interestingly, most of that rain fell on the 9th, 1.62 inches, meaning only 0.22 of an inch fell the remaining 30 days. Only 0.02 of that was recorded after the 9th, so over half of the second half of the month was extremely dry. A quick note about the rainfall total, several times during the month showers and or thunderstorms moved just south of Boston, meaning that areas south of the city received more rain. One example of this is the city of Walpole which unofficially recorded 2.82 inches.
As for sky cover there were 4 completely overcast days, 21 partly cloudy days and 6 days when it was mainly clear.
When you look back at the summer as a whole, once we got past that brutal heat wave in mid-July that ended on the 20th, we never saw 90 degrees again.
All the information gathered here was made available by the National Weather Service and the reporting station was at Logan Airport in east Boston.
