Kent experiences a Marine West Coast climate (Köppen: Csb), featuring mild, wet winters and warm, relatively dry summers. The Cascade Mountains to the east protect the city from severe arctic air masses, while the Olympic Mountains to the west provide a partial rain shadow, though the city still receives ample precipitation.
Average highs in the summer (July and August) range from 75°F to 80°F (24°C to 27°C), making it the most popular time to visit. Winter temperatures (December and January) hover between lows of 35°F (2°C) and highs of 45°F (7°C). Kent receives an average of 39 inches of rain annually, primarily between October and April. Snowfall is occasional and typically light, averaging a few inches a year, though winter storms can occasionally bring heavier accumulations. The proximity to the Green River means valley fog is a common occurrence in the autumn and winter mornings.
