Wow. My surface temp was 85.5 midday, probably a little higher later but not 98!
For sure you must have a big temp difference underneath the thermocline. All the rain may have helped, especially if you take water out of the bottom via a standpipe arrangement. Now that it's getting really hot & rain has tapered off, though, trouble may await.
How deep is your place? What are temps below the thermocline? I'd be cautious about mixing if the fish seem to be doing okay, but then I'm sure no expert.
