About Clearwater County Weather
A Wet and Temperate Northern Haven
Clearwater County averages 45.7°F annually, falling below the national median temperature for the United States. Its damp climate sets it apart from the drier high deserts typical of the American West.
Lower Temperatures but Higher Moisture
The county's 45.7°F annual average is slightly cooler than Idaho's state average of 46.5°F. However, its 37.3 inches of annual precipitation more than doubles the state average of 17.0 inches.
The Precipitation Powerhouse of the Region
While neighboring counties struggle with aridity, Clearwater’s 37.3 inches of rain and snow make it one of the wettest spots in Idaho. It receives nearly three times the moisture of nearby Clark County.
Heavy Snowfall and Mild Summer Days
Winter is defined by a massive 83.3 inches of average annual snowfall and a 29.5°F winter mean. Summers are exceptionally comfortable, with a July average of 65.8°F and only 22 days of extreme heat.
Gear Up for Significant Snow Management
With over 83 inches of snow falling annually, residents need heavy-duty clearing equipment and reliable winter tires. Proper roof maintenance is also critical to handle the heavy moisture loads throughout the year.
