I've also noticed that newer homes tend to have this problem more than older ones. They're better sealed thermally, so while they're more efficient to keep cool, when they get hot they stay hot for a lot longer. Great for winter, not so much for summer heatwaves. I used to live in an apartment built in the 70s which was a pain to cool or heat because it was so badly sealed. But the one benefit it did have is that on hot days with cool nights it'd very quickly cool off, without needing AC. My current place requires AC unless I mind waiting until 4am for it to cool off.

It's pretty easy to temporarily "unseal" a house though - open doors/windows. A well sealed and insulated house takes less to cool too, though. It doesn't just help in winter. Sadly, in central Kansas where I live, it regularly forgets to get cool at night. Last summer we did our corn silage chopping at night and slept in the day, as we were getting burned trying to operate equipment. At night it was still very hot and muggy. IIRC the dewpoint was in the mid-to-upper 80s F.
