March sits between the wet winter and the dry season. Rain is still common early in the month and tapers off toward April. Daylight saving time starts on the second Sunday of March, so evenings suddenly feel longer.

What the weather is like

Spring is often windy. Gardens in Golden Gate Park start to bloom, and the Japanese Tea Garden is a good bet on a mild afternoon. Temperatures stay cool, with highs around the low 60s.
These averages come from the downtown station. Neighborhoods near Ocean Beach are often cooler and grayer, and the Mission and SoMa are often warmer. In March the station records about 7 days with measurable rain in an average year.
What to pack
Layers work best: a T-shirt, a sweater and a light rain shell. Keep the shell even on sunny mornings, because showers can still blow in. Our San Francisco packing list covers the basics for every season.
What is on in March
