National Wind Chill / Heat Index

About This Product

This Wind Chill / Heat Index map plots either:

  1. Wind Chill (degrees F) if temperatures are below 50 F and winds are greater than 5 mph,
  2. Heat Index (degrees F) if temperatures are above 80 F, or
  3. Current Temperature (degrees F) if neither wind chill or heat index is a factor.

This map is updated every hour using data from NOAA's National Weather Service.
