Great weather today Only at 27C/81F right now. Stupid heat's coming back, but fortunately it doesn't look long lived.
I'm glad to see your area getting a break from the insane heat. I doubt my area will get super hot in August, maybe up to 90F but I think I'll see some mid 90s to upper 90s in September which has been pretty common here the last decade for some reason.
Of course. It's been really hot there in most of the other days this month, but the conditions being experienced now are closer to Icelandic weather than what they usually get. In any case, going from that sort of heat to something that could pass for real weather in Reykjavik is a notable turnabout.
True, a day with highs in the 60’s or low 70’s is a rare treat (for those who dislike hot weather) in the Tri-State area or anywhere on the East Coast south of Boston. However, as I’m sure you must know, that type of turnabout is truly fleeting…as of today, most of the Tri-State area (including the Bridgeport-New Haven/NYC area) will go right back into the typical midsummer rhythm - 80 to 90 F for daytime highs and mid 60’s for overnight lows:
What’s really interesting to me… is that despite what many people think, the summer temps are actually fairly uniform along the USA East Coast at the time of high sun from the Tri-State area (NYC/NJ/CT) south into the subtropics. Roughly, once south of New England (Boston or so)…daytime highs range from around 85 F in NYC to around 90 F in Daytona Beach, Florida…and overnight lows in the mid 60’s (NYC area) to low/mid 70’s (Daytona Beach area). The real difference is that as you move southward along the Atlantic seacoast dew points average higher and fewer and fewer fronts survive as they move southward. Also, late day thunderstorms become more common as you move into the subtropics with the intense daytime heating and more unstable air. Otherwise, unlike the cool season (Nov - March) high/low temps are not all that much different from NYC southward into the subtropics. Here is the next week north to south:

Since you neglected to post any forecast, I'll add one for you. South Hadley, MA roughly 75 miles north of New Haven:
Highs are a bit cooler and lows stay in the 60s. Let's go another 80 miles north:
changes are much more drastic. The boundary between "temperate" summer weather and "subtropical" summer weather shifts a bit, sometimes the NYC metro is on the other side, or at least close to the transition. This is more common in the shoulder season of summer rather than midsummer.
Edit: this is inland, the coast is different. Boston, same latitude to South Hadley is identical to New Haven. I'd still say New Haven is noticeably cooler than Philly southward.
going 65 miles up the coast to the Maine border (same latitude as Springfield, VT) cools a bit:
This week looks a bit above average. You'd see a bigger north-south difference on some weeks.
The GFS stupidly under-predicted temperatures for my address last night, showing us going down to 2°C. In fact it never got below 8°C and was a fairly average night here, last July did far better for cold nights with down to 4°C AFAIR. Avg Tmin is running above average here this July in-fact.
