Just like that (meteorological) summer has drawn to an end. The unofficial closing weekend is here and there remain just two weekends left in astronomical summer. While much of the country baked this summer, some may say New England barely had a summer at all.
To say rain put a damper on things this summer would be an understatement. Concord, New Hampshire saw measurable rain 36 of 92 days from June 1st-August 31st. The longest dry stretch was just 6 days, from June 18-23. Boston and Hartford both saw 38 of the 92 days drop rain. Portland, Maine saw at least a trace of rain on 62% (57 of 92 days) of days this season. Maine bore the brunt of June’s unsettled weather.
While June was consistently rainy, it certainly wasn’t record breaking. New England has had rainy Junes recently; 2009, 2012 and 2019 were similarly wet. What was different about 2023 is that the rain and clouds were basically constant throughout the entire month. There were no breaks longer than a few days from the showers and overcast skies. Boston recorded its second cloudiest June on record. It was overcast well over 50% of the time. Boston’s average amount of time being overcast in June is just 35%.

“Trained weather spotters reported thunderstorms producing heavy rain. There is significant flooding in the Hartford metropolitan area right now. Several cars are stuck in flooding on Scarborough street and the road is being closed due to the flooding. There are also other streets where cars are are stuck in street flooding in the Hartford area. Between 3 and 6 inches of rain have fallen in the last 48 hours.”
These alerts are issued for “exceedingly rare situations when extremely heavy rain is leading to a severe threat to human life and catastrophic damage from a flash flood is happening or will happen soon.” Of course, everything described in the previous sentence occurred across the state on July 10th and 11th. Recovery from this flood is ongoing and will be ongoing for a long time.
The rains didn’t stop after Vermont’s great flood. Just two days after this flooding, on July 13th, a severe thunderstorm outbreak loomed over New England. This outbreak spawned a tornado in Vermont and created more flash flooding. The following Sunday, July 16th, New England was facing yet another threat of major flash flooding.
After a one day break, the month of July closed out with another severe weather outbreak on July 29th. This outbreak brought more tornado warnings, wind damage and flooding. Flash flooding hit parts of Boston hard during this event.
In the end, July proved to be very wet, despite more sunny, summer-like weather in between the storms. Very wet may be an understatement. The National Weather Service office in Gray, Maine issued a record breaking 38 flash flood warnings for New Hampshire alone in July. This not only shatters the old monthly record of 17, but actually surpasses the most warnings issued in an entire year, which was 36.

The weather did start to calm down in August across New England. Despite this, there were issues. On August 8th, severe storms rolled through the region once again. These storms spawned three tornadoes as well as dropped a half foot of rain once again in places. Andover, Massachusetts was hit particularly hard by flooding on this day.
In North Andover, a senior housing center was forced to evacuate 150 residents when the center became flooded. Several businesses sustained heavy damage during the flash floods. Multiple store fronts were seen being boarded up after the waters receded. Nearby Lawrence saw multiple cars submerged on roadways. 6.24 inches of rain was reported in Lawrence.

In the end, rainfall amounts across New England were highly varied. Many of the storms weren’t large, soaking rains but rather small, scattered torrential downpours. Because of this, summer 2023 did not break rainfall records in major cities. Boston and Worcester did finish with the second wettest summer on record. Hartford and Portland broke into the top 10 wettest. Places like Providence and Concord just missed their top 10’s.
One place that shattered their rainfall record was the summit of Mt. Washington. Just over 4 feet of rain fell on the mountain in the last three months. The nearby town of Jackson, New Hampshire saw 31 inches.
