Washington experiences a diverse climate—from the cool, wet marine conditions along Puget Sound to the hotter, drier summers and colder winters east of the Cascade Range. Coastal cities like Seattle, Tacoma, and Bellingham tend to have mild temperatures year-round, while inland areas such as Spokane and the Yakima Valley experience wider seasonal swings. Residents across Washington—from Vancouver and Olympia to Wenatchee and Yakima—adjust their bedding seasonally to stay comfortable.
Important Note on Blanket Warmth:
Blanket warmth is subjective and depends on your personal comfort, your home’s insulation, and how warm or cool you feel while sleeping. In the U.S., warmth is often measured by weight (GSM), thermal rating (TOG), or a scale of 1–7 (with 1 being the lightest and 7 being the warmest).
