The spring and summer rains should be over by then. It won't be too hot. I would watch the sky and if you have a weather radio with you I would keep it on. Tornadoes are very common in that country in the spring and summer. Nothing to worry about but you need to keep one eye peeled. Rattlesnakes are fairly common but again not to worry just be aware. Scorpions are around as is prickly pear cactus. Have fun
