CORPUS CHRISTI, Texas — The Coastal Bend is known for high temperatures during summer, which is why every year KIII-TV teams up with the Salvation Army for the annual Fans for Friends Drive to give families in need living without air conditioning a chance to get a fan at no cost.

Heat index values climb over 100 degrees regularly this time of year in the Coastal Bend. The air often feels warmer because with more humidity in the atmosphere, your body cannot evaporate sweat as efficiently as if it were dry.

When you have wind blowing over your skin, it not only whisks away a thin layer of hot air surrounding your skin, but it enhances evaporation. The heat used to evaporate the sweat on your skin takes heat away and is our body's natural cooling mechanism.

This is the same concept as wind chill, when air temperatures are cold.
