I swim in a standard pool and count my time. However, in the summer, when the pool is hot, I cannot swim as fast as what I do in the other seasons.
For example, on a hot day, when the pool was about 30℃, my 100m interval was at least 2 seconds slower than normal.
More recently, I attempted to do a USRPT set of 50m's (target time 1', interval 1'15") a few days ago, and failed at the 22nd, 28th and 34th. However, after the hurricane, I did the same set again and completed all 40x50m's offered. I don't think it is possible to have such a large jump in performance in less than a week, and the only plausible reason may be the difference in the pool temperature before and after the hurricane.
Is it true that the pool temperature can cause such a large difference in performance?
Wow...30°C (86°F) is pretty warm. The pool I lifeguard and swim at is maintained at 27.7°C (82°F) and that is warm to some folks. Four degrees (F) may not sound like much...but when the temp goes up just one degree to 83°...people complain that it's like a bathtub. When it goes down just one degree to 81° they say it's like ice water. Is there a reason your pool is kept so warm?

It's because the weather is so HOT in summer in the southern regions of the country, that I need to stop swimming in outdoor pools in July and August.
For the USRPT thing, 40x50m is the appropriate amount for longer distance, for example, at 750 m race pace; for 1500 m training, about 24 - 30x100m may be considered.
