About Pacific County Weather
A Cool and Damp Marine Climate

Warmer and Wetter than Washington Averages
The county's 50.5°F average annual temperature stays slightly above the Washington state average of 49.9°F. However, its rainfall is nearly triple the state average of 38.5 inches, making it one of the wettest regions in the Pacific Northwest.
A Coastal Standout for Rainfall
While neighboring inland counties see far less moisture, Pacific County's 94.5 inches of rain dwarfs Skamania's 95.8 inches in intensity relative to its coastal position. It stays significantly milder than eastern counties, with January temperatures averaging a comfortable 41.5°F.

Prioritize Waterproofing Over Air Conditioning
With only 3 days above 90°F annually, cooling systems are a low priority compared to high-performance rain gear and home dehumidification. Residents should focus on gutter maintenance and moisture barriers to manage the nearly 8 feet of annual rainfall.
