San Francisco – Best time to go

Best time to visit San Francisco

Mostly, San Francisco enjoys mild temperatures year-round ranging from 5°C in winter to mid twenties in the summer. However, San Francisco has it's own micro climate and weather therefore can vary within a few miles. The weather can change by the hour, so we always suggest packing layers so you are prepared. 

Our favourite season is September to November’s when San Francisco shows us their annual ‘Indian Summer’ bringing warm temperatures and sunny skies to San Francisco. The entire bay stays smooth and glassy and the warm air sweeping in from the Central Valley makes autumn the best time to visit San Francisco. 

Best times to visit

Spring Season

Spring sees some of the sunniest, mildest, driest days in San Francisco. Unlike many other US cities, San Francisco in spring is relatively free of showers and temperatures begin to warm up, making spring a pleasant time to visit. 

Summer Season

San Francisco’s famous fog really kicks into gear in the summer. This is when you will see billowing white fog and sea spray keeping the area overcast and cool. Usually by the afternoon and early evening the fog burns off. The sun however does burn through the cloud, so although overcast, remember your sunscreen.

Autumn Season

San Francisco in the autumn is truly magical. Like many California coastal towns, this is when the fog really burns away and the sun shines the brightest. The warmest months of the year in San Francisco are August through October and usually the most dependable. Nights are mild and clear and rainfall is rare. 

Winter Season

Winter temperatures are relatively mild, even in San Francisco’s coldest months December and January. Snow and frost are rare, although rain is not, with storms raging in from Mexico bringing torrential downpours throughout the winter.
