The title says it all. If I'm standing in the wind and I'm wet, I feel much colder than when I'm dry. This is true no matter how warm or cold the water. Why is this?

When I blow on someone my feeling is totally independent from the victims moisture. ""Why does blowing on someone who is wet feel colder than on someone who is dry?"" – Georg Nov 4 '11 at 14:54

Am I the only one who is thinking of dirty things when reading that title? – Nick Kidman Jul 9 '12 at 21:14

Evaporation of sweat from the skin surface has a cooling effect due to the latent heat of evaporation of water (from wikipedia). Basically, the heat is transfered from your skin to the water, the water then evaporates, taking with it a bit of the energy stored in it.
