We live in GA and camp in both GA and FL, spring, summer, and fall. We like warm weather, so we adapt when camping. Our awning provides much needed relief from the FL and GA sun. We have an oscillating fan blowing on high to keep the the no see-ums, gnats, and mosquitos at bay, and also to provide a welcome breeze. We avoid the heat of the day at the campsite, preferring the beach or an outing.
We put the top of an old beach umbrella over the dogs' x-pen for shade (would use two if you hook two pens together). We also use dog folding beds from Camping World to keep the dogs off the sandy ground and away from ants, sand fleas, etc. We attach a crate water bowl to the inside of the x-pen to provide much needed water for the dogs and keep it away from other thirsty critters.
If you're not a fan of heat, avoid summer camping.
