All Months
April through October gives you San Rafael at its finest. Spring brings wildflowers to the hillsides and perfect hiking weather – 65-75°F with minimal rain. May and June are ideal if you want green landscapes without summer crowds.
Summer gets warm, hitting 80-85°F regularly, but the marine layer keeps things comfortable. This is peak family season, with school breaks bringing more visitors to nearby attractions. Book accommodations early.
Fall might be the sweet spot. September and October offer the warmest weather of the year, often reaching into the 80s, while tourist numbers drop after Labor Day. The hills turn golden, creating that classic California landscape you see in movies.
Winter isn't terrible – temperatures rarely drop below 45°F – but rain can disrupt outdoor plans from December through March. The upside? Hotel rates drop significantly, and you'll have hiking trails mostly to yourself on clear days.
