Influence of Topography and Proximity to the Ocean

Bellingham’s cloud cover and precipitation patterns are strongly influenced by its topography and proximity to the ocean. The city is situated in a valley surrounded by mountains, which forces moist air from the Pacific Ocean to rise and cool, leading to condensation and cloud formation. Additionally, the presence of the Salish Sea, a large body of water located just west of Bellingham, further contributes to the region’s high humidity levels. The warm, moist air from the ocean is readily available to form clouds when it encounters the cooler, mountainous terrain. As a result, Bellingham experiences frequent periods of cloudiness and precipitation, contributing to its overall temperate and humid climate.
