1. Re: Weather/water temp in Clearwater in mid-late September. Apr 11, 2008, 11:14 AM. Weather will be very nice. Not quite as hot and humid as June/July/August. The water will be plenty warm. Still could be getting the Summertime afternoon rains where it will rain for an hour or two, then be sunny again. It will be hurricane season.
