End of July and first half of August will be humid for sure but I think heat waves are done in most of New England after next week.
I'm confident there will be 84-88F days with DP's in the upper 60's but the spectacular real feel temps are over by the 18th.
I like summer weather, don't love the HHH days but the past 2 weeks have been a fun stretch because it's nice to hang out, outside at 10pm, in shorts and t-shirts.
