So in my experience the things that help us Southern boys cool off at night are:
- Camping near water, Open water such as a lake creates a small costal wind effect where as camping near a river seems to create a steady wind direction all night.
- Place a wet bandana or pack towel over your chest and the evaporation of moisture will work like a heat pump helping pulling heat from your body.
- A small battery operated fan hung from the ridgeline creates a steady breeze tillt he batteries run out. Try hanging it at one end so that it blows over your entire body.
- If you can't afford the batteries for the fan, because lets face they can get heavy in your pack, find a nice Southern Baptist grandmother to go camping with you and setup down wind of her church fan. Because let's be honest they can really get those things going. :D
Even the lightest of breezes feels great in a hammock, and although we need the bugneting in the hottest of months, we can still stay comfortably cool with good site selection and some forethought.
