Annual climate pattern

Analyzing the transition from wet winters to dry, warm summers across twelve climatological months

Monthly Climate Normals and Temperature Ranges in Lassen Volcanic National Park

Climatology records at 1700.49 meters reveal average minimums dropping near minus twelve degrees Celsius in January, while average maximums peak above thirty-four degrees Celsius in July. Daily precipitation averages over five millimeters during the winter months before dropping below one millimeter in summer, establishing a distinct dry-season pattern.

Twelve-month climate

Comparing temperature bounds, daily precipitation rates, and calculated daylight hours across the calendar year

Lassen Volcanic National Park Weather by Month and Monthly Climate Normals

Climatological data from 1991 to 2020 at a representative elevation of 1700.49 meters enables a direct comparison of average minimum, mean, and maximum temperatures alongside average daily precipitation rates. Tracking relative humidity, average wind speed, and calculated average daylight hours across all twelve months reveals the long term seasonal patterns of the park without relying on simple annual averages.
