The Fire Weather Index is a component of the Canadian Forest Fire Weather Index (FWI) System. It is a numeric rating of fire intensity. It combines the Initial Spread Index and the Buildup Index. It is suitable as a general index of fire danger throughout the forested areas of Canada.

More information about the Canadian Forest Fire Weather Index (FWI) System and Fire Weather Normals is available in Background Information.

Fire Weather Normals represent the average value of a fire weather code or index over the 30-year period from 1971 to 2000.
