When to Go— Timing Your Trip by Season

Spring. The color show in spring is spectacular. Wet, mild and windy pretty much sums up spring weather on the peninsula. Spring showers bring a big payoff. The Olympic Peninsula has the perfect climate for growing flowers.

Summer. Aaaah. It’s what we wait for in the Pacific Northwest. Generally, you can plan on fair and warm weather. Afternoon temps average 65 to 70 degrees. If the gauge hits 85, expect semi-stunned locals to start fanning themselves. Afternoon summer breezes are typical, and things cool off considerably in the evenings. Late summer often brings ocean fog and clouds that move inland and usually hang around until midday. Rainfall during summer months is typically light, but you just never know.

Fall. Cool and wet is the forecast for fall, with typical temperatures ranging from 35 to 65 degrees. Early snow storms are possible in the mountains, and expect those foggy mornings to continue through early fall (pairs well with a cup of coffee).

Winter. From valleys to coast to mountain peaks, winter weather can vary greatly. In general, expect afternoon temperatures in the 40s, dropping into the 20s or 30s at night. Wind storms aren’t unusual. Lower-elevation snow is possible, but you likely won’t see more than 6 to 10 inches at most. The heavy accumulation is higher up. Hurricane Ridge averages a whopping 400 inches of snowfall each year.
