I hunt them inthe summer all the time, but 95 degrees and 100% humidity takes getting used to. I've had more than one person border on heat stroke. I stay in the shade and hunt early morning and night stand. Don't do much spot and stalk in the summer either. Swirling wind directions and impossible scent control will just have you pushing pigs around all day never really seeing one. Hunt the spots between wallows and cover. They need to hit those a few times a day to keep cool and keep the bugs off.
