You now how when you feel a light breeze it feels kind of cool? Why? Atoms are moving faster and they hit your skin with higher velocity so I would think wind would be hotter than normal.
But it's a good one. When you are sweating, the breeze can cool you through evaporation, even though the air temperature is not cool. Evaporation can cool you...A rather unexpected answer

“Air is an excellent insulator (R = 5.5/inch), as long as it does not move. It has poor conduction but good convection properties.”
This, by the way, is why things like styrofoam and rock wool are good thermal insulators. They capture air, which is a good insulator, and make it very difficult for it to move.
