Hey U.
Did my PPL in FL over the same months and didn't have many delays due to weather. Like any place that gets hot during the day, try and fly just after sunrise. This I find is probably the best time to fly! I also did a little evening flying in FL once all the storms had moved offshore.
As long as you can hold complete respect for a thunderstorm and give it at least a 20nm+ wide birth you'll be fine. Yeah you are gonna be hot and sweaty until the fan starts but in my opinion its better than freezing you're bits off!
Hope you enjoy it and good luck!
