My experience has been the opposite. When its warm and dry here, other than running the SWCG (no more than usual), I hardly have to do/add anything. Its when we get a bunch of rain and I have to pump excess water out of the pool that my chemical use goes up (salt, stabilizer, borates in particular).

Perhaps the big jump in chemical demand the pool store guy mentioned was due a combo of warm water and insufficient chlorine levels resulting in more algae blooms?
