if it is hot and windy outside, what do they measure: wind chill or heat index?

They measure the velocity of sustained winds and direction and give particular attention to gusts. Not much of a chill is noticeable in arid climates and heat is a factor since it can kill.

I live in a place where it is usually windy when it is hot, and they never give wind chill when reporting conditions. It would be interesting, though, because I think you feel much cooler at 100 degrees if there is a 30 mile per hour wind blowing than if there is none. Heat index is given around her occasionally when it is windy, but since it is alway dry at those times the heat index is less than the actual temperature.

I suppose one could determine a wind chill, since it is a function of wind and temperature, though it is not significant when it is hot. The Heat Index is a function of temperature and relative humidity. The wind is not factored into the Heat Index.

It is mathematically possible to calculate the wind chill and heat index at any temperature. The wind chill technically starts at 50F. This case would you would use the heat index.
