Twelve-month climate

Analyze seasonal variations in average temperature bounds, daily precipitation rates, wind, and calculated daylight hours

Katmai National Park and Preserve Twelve Month Climate and Weather by Month

Monthly records from the 1991 to 2020 climatology period reveal how average temperature bounds, relative humidity, and wind speeds shift across the year at a representative park elevation. Evaluating the average daily precipitation rate alongside calculated average daylight hours provides a far more complete profile of Katmai National Park and Preserve than a single annual average.
