Variations of fuel moisture and related parameters attributable to degree of slope were studied by establishing fire weather stations on six land surfaces of the same elevation and aspect but varying from 0 to 62 per cent in steepness. Mean maximum daily temperature was found to be directly related to degree of slope while mean minimum temperature was inversely related to degree of slope on all classes of days. The maximum difference was approximately 40F for the former and about 50 for the latter. Afternoon fuel moisture content tended to be from 1 to 2 percentage points less on the steeper slopes. The conclusion is drawn that degree of slope is a minor factor in microclimate compared to the location of the slope in respect to the surrounding topography.
