California experiences a varied Mediterranean climate with mild, wet winters and hot, dry summers—though conditions vary by region. Coastal cities like San Francisco, Los Angeles, and San Diego tend to have more temperate year-round conditions, while inland areas like Sacramento and the Central Valley experience wider seasonal swings. Residents across California—from Venice Beach and Napa to Palm Springs and Pasadena—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).
