Best Time To Visit San Francisco

By Sasha Yanshin | Updated on 6 November 2019

San Francisco is known for its unique climate and the fact that the weather remains good throughout the year. The locals boast that you can wear shorts and a t-shirt all year round, although that is a definite stretch in the middle of the winter.

The best time to visit San Francisco is in September and October. The peak tourist season ends in August which means less crowds, the weather is at its best in early fall and there are great events and festivals on throughout September and October.

To help you choose when to go to San Francisco for the weather (and to avoid the fog), things to do or to catch a festival, read our guide below.

When should you go to San Francisco?

When to visit San Francisco - Summary

  • Best Time for Good Weather: September to October has the best weather of the year in San Francisco. These are the two warmest months, there's no rain and the summer fog has long cleared.
  • Best Time for Sightseeing: All the main attractions and things to do in San Francisco are open year round, so visiting in March to April and September to October is best to avoid the crowds and the summer fog. Winters are great with few other tourists around and the weather being mild, but you might catch some rain and a lot of the best sightseeing in San Francisco is outdoors.
  • Best Time for Saving Money: January and February are the cheapest months to visit San Francisco. The winter season is generally the least popular with tourists which brings hotel and flight prices down and while November and December bring holidays and the festive season, January and February are generally quiet.
  • Best Time for the Beaches: Despite its balmy weather and seaside location, the beaches in San Francisco are not the best for swimming - the water is bitterly cold and there are very strong currents going right up to the shoreline. Aquatic Park or Crissy Field are the best beaches if you do want to swim and the water is warmest in September and October at the end of the summer.

Best time to visit San Francisco

  • Best Time for Shopping: San Francisco shopping is great all year round with large malls, shopping streets and markets open in all seasons. Sales start after Christmas and run through January if you want to pick up some bargains and the shops tend to be more quiet than over the busy retail season around Thanksgiving and in December.
  • Best Time for Museums and Activities: Museum and key sights' opening times and prices are the same throughout the year without any seasonality - it's best to avoid the summer months as the high tourist season can mean queues to get in and having more people wherever you turn to.
  • Best Time for Restaurants: January to May and September to early November are best for eating out in restaurants in San Francisco. The summer months are very busy with tourists which can make your evening out crowded and it can be hard to find a table. Thanksgiving and the Christmas season attract a lot of family gatherings, office parties and other events which can be frustratingly loud when you're wanting to enjoy your meal.
  • Best Time for Concerts and Music: The San Francisco music scene comes alive in the summer with concerts and festivals from June to August. October and November are also great for more niche music festivals and local events ranging from Hip Hop to Bluegrass.
  • Best Time for Families and Kids: September to October if you can avoid the need to come during the summer school break. The weather is perfect and not too hot and there are less tourists making for a perfect family break.
  • Best time to Avoid Crowds: The least busy season in San Francisco is in January and February with few tourists in the city. If you want to avoid the coldest and wettest part of the year, consider coming in the first half of November when the crowds are gone, but the weather often holds up.

San Francisco travel seasons

High Season for Tourists (June to August)

The peak travel season in San Francisco lasts through the summer months from the beginning of June right through to the Labor Day Weekend at the beginning of September.

Tourists from across U.S.A. and abroad fly in during the summer holidays and flights, hotels and other travel costs are at their highest.

Popular tourist attractions are busier between June and August even though the weather is not at its best during the early part of the High Season.

Shoulder Seasons (March to May and September to October)

Spring and fall tend to have less visitors than the summer months. Families with children can't visit San Francisco due to the school semesters and fewer people choose to visit outside the summer despite the weather and high prices.

September and October are surprisingly quiet despite the best weather of the year in San Francisco coming in the fall. A number of business events and conferences bring some visitors to town which means hotel prices are not as cheap as during the winter.

Low Season (November to February)

As the weather turns cooler, the low season for tourism in San Francisco starts from November and runs through to the end of February or early March.

Even though San Francisco winters are only cold by West Coast standards, demand for hotels drops considerably during the winter. With the rain setting in and the wind chill, it can feel considerably colder than the 52 °F (11 °C) that the average mean temperatures would suggest.

Best time to visit San Francisco for scenic views of the city

San Francisco has some of the most stunning city views you'll find anywhere - the Golden Gate and Bay bridges, Alcatraz and Treasure Islands and the steep hills make for amazing views everywhere you look.

If you want to snap some great photos and capture the sights, it's best to come to San Francisco in April or from September to October. These months are clear of the summer fog and don't carry the risk of winter rain which gives you the best opportunity to see the city in the best possible light.

Weather in San Francisco across the year

Weather in San Francisco is relatively consistent throughout the year without big temperature swings between summer and winter seasons. The main factors that affect the weather are the winter rains and the summer fog.

Average rainfall in San Francisco can be deceiving as the different years have very different patterns depending on the El Niño cycle with some years having a very wet winter and others having almost no rainfall at all. Even during the wet years, the rain tends to come in large quantities on a few days, rather than persistently falling through from December to February.

Summer fog is a big factor in San Francisco, as it is for much of the U.S. Pacific coast. Typically occurring in June, but often spreading into May and July, the fog can sit heavily in the Bay Area and can make the warmer temperatures fell a lot cooler. The higher humidity and damp effect of the fog makes early summer a bad time to visit San Francisco.
