Fire Weather Normals for Fire Season

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.

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

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