It's true, when it's very warm and dry, you really feel more thirsty and your lips get all dry, at least when it's damp or humid you absorb the moisture through your skin!
I tend to find the opposite. Generally, if it's humid (like today
), I find myself drinking upwards of 10 litres of water/day just to stave off heat exhaustion (that applies whether or not I'm riding). I don't have this problem in the drier conditions.
