We have camped in June but we live down here and are used to the heat. Well, as used to it as you can get. Here's how we did it. We tried to get as shady a site as we could. We put a tarp under our tent to help not have water come up thru the floor during any rain that you are most likely going to get. We put a 12x16 tarp over our tent and added a 12x12 dinning canopy onto the edge of that so we had a 12' x 28' area under cover. We brought a couple of box fans for around the site and a small oscillating fan for in the tent. I put a 5000 btu 110v A/C on a dolly that I could roll up to the door of the tent and zip the door around the front of the A/C. The A/C did just OK in the day but at night we needed cover and slept very well. I have also seen other tent campers that used the large carport type canopy to cover most of their site. A tent sitting in the direct sun in the middle of the day can easily get well over 100*. I can't stress enough how important it is to have a cover over your tent for shade and rain protection. We camp in a popup with A/C now and I still put reflective covers over the tent ends. It makes a huge difference.
