This paper analysizes wind speed and direction distributions obtained at nine forestry stations and nine airports across Canada. The effect of differences in the distributions on forest fire danger rating is discussed. The major finding is that forestry stations have a significantly lower average wind speed than airports and the difference between the two decreases as wind speed increases. This difference caused a considerably greater percentage of days to all in the extreme fire danger class at the airports. The data did not permit the derivation of a function relating the wind speed ratio the size of the clearing at the forestry station.
