Larkspur in September
Great time to visit
September is Larkspur's secret weapon - better weather than summer but fewer crowds as families head back to school. Many locals consider this the absolute best month to visit.
Weather
September often delivers Larkspur's most pleasant weather as the marine layer lightens and temperatures moderate to a perfect 24°C. This is when locals say summer really begins. Expect warm, sunny days with crystal-clear views and virtually no rain.

All Months
April through June brings the best weather — sunny days in the 70s with minimal fog. The hills turn green from winter rains, and you can actually see Mount Tamalpais clearly. September and October offer similar conditions with warmer temperatures.
Summer means fog. Lots of it. Mornings start gray and cold, then maybe clear by afternoon. Pack layers always. July averages 65 degrees, which shocks visitors expecting California heat.
Winter brings rain but also fewer crowds. January through March sees the most precipitation, but you'll have restaurants to yourself. The ferry still runs, and indoor activities like wine tasting work perfectly. Just bring waterproof shoes for those creek-side walks.
