I was curious how extreme this was in comparison to the past. I grew up near Philly so I looked at the Mount Holly historical data set. Since 1996, that’s the cutoff of the data I found, there’s been 4 summers with two 100+ days in a row in them. Zero instances of three in a row. Honestly it’s rare enough I didn’t believe it had ever been over 100. But it does seem like it’s a once every 10 or so years event. I’d already made plans to go to Florida. I guess I’m going there to avoid the heat this year.

Disclaimer: not trying to make a climate statement here just genuinely curious.

Honestly I'm looking forward to it. IMO June here in NJ has been a bit too cool this year for beach/pool weather.

Hot summer weather is a UK tabloid perennial favorite, but obviously it hits a bit different here in the US when you've got A/C to go home to!
