We see triple digit heat mid august I say. The worst of it is NOT over just cause we're having a little break from the extreme heat/humidity first week of august. Many people are jumping the gun on second half of summer.
It is very very difficult for nyc to get <70 in mid summer now. I think we scratch 70 but struggle to get below it. First <70 night will come some time deep into august or even early sept.
In urban areas I feel august is way worse. It's been baking for too long and all the concrete retains the heat. Plus the humidity is just as bad as July.
Well if you are one of the 8+ million people that live in new york city proper, or the surrounding urban areas like Jersey City and Hoboken, you never get a nice refreshing night anymore. That seems like kinda a big deal.
Pretty much all the lows have been affected region wide, in every season. Compared to say 80s climate normals our overnight lows are 5-6 degrees warmer now, regardless of the season. Crazy shit especially for only a 40 year difference.
Our summers are basically miami tier now, except with the highs being about 4-5 degrees cooler on average. The lows are startlingly similar, mid 70s (yuck).
Our July/August core summer weather is now startingly similar to miami's. The total lack of lows in the 60s in startling. Mornings are no longer refreshing, its just gross 24/7 during these months.
