Guemes Island Weather
Guemes Island’s weather overall is somewhat mild. It’s location within the banana belt of the Pacific Northwest and with the beautiful Olympic Mountains creates a rain shadow. Guemes Island has mild winters, an extended spring, and fantastic summer months. July and August are the warmest with an average temperature in the mid-70s. The wettest months are November and December with an average rainfall of 3.8″. Knowing from experience with my job which requires working outside all year, there is overall a great number of days the winter weather is not too bad. However, it does get a bit windy in the winter time!
Could be a great day to go for a hike on the Guemes Mountain Trail.
