While San Francisco's famously bohemian vibe goes strong all year long, its mysterious weather patterns and microclimates can flummox visitors, running counter to typical travel schedules.

There's no bad time to visit the "cool, grey city of love," however, whether you're looking to lay out on hippie hill in Golden Gate Park or dine in at one of the city's storied restaurants. 

Here’s our guide to help you decide the perfect time to visit San Francisco, California.

Fall in San Francisco: August to October

Sunny days and street fairs

Unlike the foggy chill that accompanies the early summer months – and sometimes takes visitors by surprise – the late summer and early fall are some of San Francisco's best months to get outside and stretch your legs on the city's famously hilly streets and natural areas. 

August, September and October are best for warm weather, street fairs and enjoying California's farm-fresh cuisine at its peak. If you're hoping to practice your photography and get fog-free shots from promontories like Corona Heights Park, Coit Tower, or looking back at the skyline from Alcatraz, this is the time of year to shoot your shot.

Winter to spring: November to June

Avoid the summer crowds and take advantage of the way San Francisco's weather refuses to synch with the traditional ebb and flow of travel season. You'll find paradoxically balmy temperatures throughout late fall and spring time, though winter itself is still chilly.

As always, pack plenty of layers –  while microclimates add magic realism to San Francisco, they can flummox visitors. When it's drizzling in the outer reaches of Golden Gate Park, it might be sunny in the Mission. A difference of a few degrees between neighborhoods grants permission for salted-caramel ice cream in Dolores Park, or a hasty retreat to tropical heat inside the California Academy of Sciences' rainforest dome. This town will give you goosebumps one minute, and warm you to the core the next.

Summer in San Francisco: June to July

Lower temps and higher occupancy rates

Grab your coat and a handful of glitter, and enter a wonderland of fog and fabulousness. So long, inhibitions; hello, San Francisco! Summer may see the greatest number of visitors to San Francisco (and higher hotel rates as a result), but it when the weather is the dodgiest.

But this is also the season when the city is in some ways most itself, with epic Pride celebrations that rock The Castro, the Haight Ashbury Street Fair, and plenty of visits from Carl the Fog. Summer is the perfect time to take advantage of San Francisco's famously fantastic food scene, its independent bookstores, its charming bars – and a still-packed schedule of can't miss events indoors and out.

Reasonable room rates and weekends crammed with cultural events will put some spring in your step in San Francisco.

They host an epic event in Golden Gate Park each year that blends Easter bonnets and rock-n-roll messiahs.

Or shake your tail feathers in the Mission and conga through the inevitable fog during Carnaval.

Since 1970 SF Pride has grown into a month-long extravaganza, with movie premieres and street parties culminating in the million-strong Pride Parade.
