It builds up

I was just looking up why it feels hotter at night than during the day. Because it's definitely a real phenomenon. It's currently in the high 70s and feels muggier than it did during the day when it was in the high 80s. Apparently it's a matter of the ground absorbing heat during the day and releasing it into the atmosphere at night. Which feels like a reason to be glad days are getting shorter.

I've wondered why winter gets colder after the shortest day of the year and conversely summer gets hotter in the opposite circumstance. I do know why but it's amusing to indulge idle thoughts on occasion. Just because we know a thing doesn't make it logical.

It makes sense that the ground releases the heat it gained during the day - there'd also be an increase in humidity which would make it harder for the body to cool itself.

Moving air definitely helps so hopefully your fan is working to keep you more comfortable. Yes, September won't be long now.

Whether late summer will be hotter--and conversely whether late winter will be colder--depends on latitude and variations in air currents. Here it's currently cool and pleasant in comparison to most of July. But it is true that you rarely get to the extremes on the solstice days. These things are always worth questioning. George Orwell had an essay where he questioned whether the Earth was actually spherical, although he finally concluded it was.

'Tain't the heat, 's the humidity, as they say. Although I've heard dry heat has its own challenges.

A good fan is one of those simple things that can make life better. And September is just around the corner.
