Wind Speed and Gusts

Wind speed is typically measured in miles per hour (mph). Gusts are sudden, brief increases in wind speed.

Humidity and "Feels Like" Temperature

Relative humidity affects how temperature feels. High humidity in summer makes it feel hotter ("heat index"), while low humidity in winter can make it feel colder.
