It’s official, Boston broke the temp record Monday

“We'll have one more unusually hot day, in the upper 70s.”

Boston broke its daily high temperature record on Monday, as summer-like temperatures settled on the city alongside the fall foliage.

The National Weather Service said both Boston and Hartford set new records for Oct. 21 by reaching 83 and 86 degrees, respectively. The previous record for that date in Boston was 82 degrees, set in 1920.

The “unseasonable” warmth is forecast to continue through Wednesday, according to the service.

“We’ll have one more unusually hot day, in the upper 70s,” forecasters wrote.

The high temperatures will give way when a series of cold fronts move into the region on Thursday and Saturday, bringing back temperatures typical for the end of October. The incoming weather patterns will result in below normal temperatures by Sunday and Monday, according to the service.

“By Sunday and Monday, daily highs will only climb into the 50s, with overnight lows in the 20s/30s expected Monday morning,” forecasters wrote.
