Heat just sucks. I’m fine with warm weather, but my assumption here is that you mean temperatures > 30°C.
Rain is at least useful as it waters the plants for me, so my lazy @rse can remain ensconced in a chair or something.
Coldness is a close second for worst weather, but at least it doesn’t induce a lasting stench of BO in public places.
Hail is basically rain 2 electric boogaloo. At least here in the UK, hailstones are tiny and are basically harmless, but elsewhere in the world they can be lethal- though I’ve never experienced hail of that kind.
Thunderstorms are pretty. Just make sure you’re observing them in a safe place and not standing in the middle of one.
