I am more of a cold weather person than a hot weather person. However, cold does tend to slow down the movement of my fingers, so working outside without gloves is very challenging. This information is derived from NOAA. Here is a heat index chart.

NOAA provides the following equation for calculating wind chill:

Wind Chill (°F) = 35.74 + 0.6215T -
                     35.75(V^0.16) + 0.4275(V^0.16),
         where T=Air Temperature (°F),
                     V=Wind Speed (mph)

Wind (mph)	Temperature (°F)

Note: Even NOAA uses both "windchill" and "wind chill" on their website, so
the two forms appear to be interchangeable.
