Temperature changes when a cold front comes through will definitely soften a kite. Also, if the water temperature is significantly lower than the air temperature, a wet kite will lose some pressure. Remember Boyle's law P1V1/T1=P2V2/T2. If Temperature drops and V1=V2, then P2 drops in proportion to the Temperature drop.
Very true, also if it starts to rain, it will often cool the kite so it gets soft.
Even when it stops raining, the huge temperature drop because water evaporates, will soften.
Same as if kite drop even gently on the water so wet (in sunny conditions), and is relaunched - the water evaporation temperature drop now can be massive, giving a softer kite.
BUT, I have hardly never seen a kite getting "hard" again later, as it should
Maybe I havent waited sufficiently long for it to dry and heat up fully
