What’s the weather like in San Francisco in March?

In March, the Californian city of San Francisco is showing signs of spring with slightly warmer temperatures across the city. The month is still relatively cool and can be showery, so make sure you pack for all weather with lots of layers and a rain coat. To boost your chances of warmer weather and clearer skies, visit San Francisco at the end of March.


The average daytime temperature in March is a mild 11ºC, with highs of 16ºC and lows of 9ºC overnight. With around 79mm of rain over the course of the month, and ten wet days on average, there’s a reasonable chance you’ll experience showers although any rain should be fairly light. The skies above San Francisco have around 50% to 60% cloud cover most days, with sunrise at 6.30am and sunset at 6pm at the start of the month. The sea is still a chilly 12ºC in March, so it’s worth visiting later in the year if you’re after a beach holiday.
