There’s so much to see and do in San Francisco that it’s nearly impossible not to fall in love with the city! Its liberal, quirky, artsy, casual attitude mixed with its incredible restaurants, bars, outdoor spaces and architecture make the Golden Gate City worth visiting in every way.
But it’s typical weather conditions surprise many outsiders. This doesn’t mean that SF doesn’t have days of excellent weather, and – no matter what – rest assured that the city always has plenty to offer!
When deciding the best time to visit San Francisco, there’s a lot to consider – like what weather conditions work best for your desired list of activities, when prices and tourist crowds are at their highest (and lowest) and unique events that are offered throughout the year.
When is the best time of year to visit San Francisco?
San Francisco may be one of the most popular cities in sunny California, but it’s actually not as hot and sunshine-dominated there as most people think. In fact, the weather is quite unpredictable and chilly in the summer. One of the biggest factors affecting San Francisco’s conditions is the infamous fog. Thick, wet daily fog make June and July particularly cold and require packing sweatshirts instead of typical summer tank tops!

The good news is that the best time of year to visit San Francisco is not when tourist crowds and travel costs are at their peak – which is in the summer. The best time to visit San Francisco is actually in the early fall or late spring when the weather is best – and also happens to be the low tourist season.

Is San Francisco safe?
While nowhere in the world is 100% safe, as long as you use your common sense, you’ll likely be fine in San Francisco.
Having said that, you should NEVER travel without proper travel insurance. We’ve tested all of the best travel insurance providers, and World Nomads is our favorite!

What months are the best time to visit San Francisco?
As mentioned above, the most ideal conditions weather-wise, tourist and price-wise, happen in late spring and early fall. This is particularly the case in September and October, making them the best months to visit San Francisco. The average high in both months stays in a pleasant 70-72℉ (21-22℃) range, which is the city’s highest of the year. There’s also the added bonus of infrequent rain and little fog.
In addition to weather and tourist considerations, factor in the special events and activities taking place throughout the Golden Gate City. There’s stuff happening year-round, so take a look at your options and see what piques your interest!
