High overcast and a warm day is one of my favorite types of weather. My favorite part about Southern California's climate when I lived there were the days that we would get some super high overcast streaming in from remnant monsoonal moisture. The cloud textures you get with instability at that level feels very tropical or something, and it makes the heat feel pleasant and non-oppressive when the sun is blocked out by clouds. Plus I love being able to see the mountains and everything underneath the cloud deck.
This will piss you off even more: I genuinely believe that the only thing worse than an average mid-summer day here is the first warm and very sunny day in early spring.
Bright blue skies on fully dead vegetation with zero greenery is deeply unsettling to me. All it does is emphasize how dead and gray the landscape is. If it's going to be warm, it needs to be green and lush. If it's not green and lush, then it needs to be cold and cloudy so it's cozy.
It'd also be nice if we actually had clouds over the summer. And a good breeze as well. Like... At least a couple. But nope. It's just endless blue sky for weeks on end in July. Completely stagnant, no breeze. Sun angles right at you.
