Cheap flights to San Francisco

Countercultural center, pioneering technology hub, party destination – fog-covered San Francisco is many things to many people. From colorful Victorian houses to towering steel bridges, all around the bay there is plenty to capture the imagination.

When to book flights to San Francisco

San Francisco has a mild climate all year round, with temperatures rarely going over 75 degrees or dropping under 55. However, there are still definite seasons and you will need to bring clothing suitable for the time of year you visit.

The city is prone to fog, with large banks rolling in and covering the area, and this can be a little chilly. Visit in the months of May, October and September when there is more chance of sunshine.

The summer is cool and foggy, with winds sweeping in off the Pacific. This is peak tourist season, when getting tickets to some of the top attractions can be nearly impossible, especially Alcatraz. Flights to SFO and accommodation can also be difficult and more expensive at this time of year. So, make sure you book early.

If you’re keen to avoid the cooler and wetter months, then stay clear of December through February.

Main airports in San Francisco

There are two main airports serving the San Francisco area. Of the two, the biggest is San Francisco International, located 13 miles south of the downtown area. It has flights to and from multiple North American destinations, as well as being a gateway to Europe and Asia.

The other airport is Oakland, located on the other side of the bay. With around 13 million passengers a year passing through it, it’s another option for cheap tickets to San Francisco.

How to get around in San Francisco

If you’re arriving at San Francisco International, then the BART public rail system is the quickest way of getting to the city. It will cost less than $10 for a one-way ticket.

You can also catch the SamTrans bus, which is much cheaper at around $2 dollars for a single journey and $6 for a day pass.

It’s possible to walk around many of the downtown attractions, but if you want to see the bridge and Golden Gate Park, catching a bus is a good idea. The city is famously hilly, which makes too much walking or cycling a bit difficult.

What are the must-sees in San Francisco?

The city is bursting with iconic attractions, from the Golden Gate Bridge to Alcatraz island. If you want to visit the world’s most famous prison, then you’re advised to book well in advance, especially in the summer, as the wait can be weeks long. The bridge can be seen from many parts of the city, but it’s well worth heading up to Golden Gate park for some of the best views.

Visit the Haight-Ashbury district, the birthplace of the hippies, and where you’ll find colorful streets teeming with vintage clothes stores. Chinatown is another exciting part of town, with exotic smells drifting on the air. Or, you can hit the shops at Union Square to pick up some designer labels.

Tips for travelling in San Francisco

The weather can have a big impact on your trip, so it’s worth checking the forecast before you travel.

San Francisco When to Go

San Francisco’s climate is mild year-round, so you can forget about packing wool underwear and parkas—or shorts and tank tops, for that matter. Though daytime temperatures rarely rise above 75 or drop below 55, there are still definite seasons.

The months of May, September, and October have less fog and, locals contend, the best weather. You may want to time your trip to coincide with one of San Francisco’s popular annual events, like the wacky Bay to Breakers seven-mile cross-town run/walk each May. The Mission District holds Carnaval in late May as well. 

Summer is notoriously cool, with fog and chilly breezes sweeping across the city from the Pacific Ocean, although parts of San Francisco known as “the sunbelt”—the Mission District, for one—often remain balmy. Summer is also peak tourist season, when getting a seat on a cable car without an hours-long wait or nabbing a ticket for an Alcatraz tour can be near impossible. Late June’s LGBT Pride Celebration and Parade is one of the biggest in the country.

December, January, and February are the coldest and wettest months, though February does bring the colorful Chinese New Year’s Parade.
