Until now, all my skiing has been during the (local) winter. I recently had a spare day while in Switzerland, and found that one of the nearby resorts was still open, so for the first time I tried some late season skiing.
Some aspects of the skiing were the same as I'm used to, but some things were surprisingly different, and I wished I'd known about that beforehand so I could've planned better. (The biggest two were around the amount of water I'd need to drink, and how much the snow changed during the day)
Aiming at someone with some winter skiing experience, trying out late season (or perhaps even summer) skiing for the first time, what do you need to be aware of?
