Manhole covers are a bit of a gamble really. Some permanently sealed, others so full of debris they won't budge. Others are a total pushover. Although you probably know this already, never lift a manhole cover if you don't know its location unless it's an emergency. Getting your head knocked off by a truck isn't worth it.
Best way to get them up in my experience is to give it a sharp smack with the palm of your hand on one corner. Then do the same on the opposite side, work your way around.
You'll know soon enough if it's going to lift. Just keep your head down, and avert your eyes from the stream of debris that is most certainly going to pile up in your eye sockets
Just don't get too carried away fiddling with the damn thing that you lose concentration on your surroundings - some of the shafts leading to covers can be a very long way up, and if you slip off the stepirons and fall, Y'all going to have a very bad time
As for the temperature, it varies also. I've been draining in winter and sweated buckets. Other drains I've done in the middle of summer have been nice and cool. Depends on the construction of the drain and the airflow through it - It's the humidity more than anything.
Hope that's helpful man, Safe exploring!
