San Diego bursts with world-famous attractions for the entire family, from sandy beaches and kid-friendly hiking trails to its famous zoo and the museums of Balboa Park. But for many, the year-round good weather is what seals the deal. As northern parts of the country dig out the coats for fall and winter, surf swells build and warm temperatures linger in San Diego, with mostly dry days right through to November.

The weather isn't the only thing that draws travelers to this happy West Coast hub. San Diego calls itself "America’s Finest City" for a reason. Its breezy confidence and sunny countenance filter down to the folks you encounter every day on the street. San Diego's neighborhoods feel like a collection of villages, each with their own personalities, but this is the nation’s eighth-largest city. For its size, there's probably nowhere more laid-back on earth.

Whenever you choose to come, we promise you'll be pleasantly surprised. Here are the best times to visit San Diego.

Shoulder Season: September to October, March to May

Best time for hikers and budget travelers

San Diego has hiking trails snaking out into the countryside all around the city, and the shoulder season is the prime time to enjoy them as temperatures are warm rather than sizzling, and the skies remain crystal clear. Fall brings strong swells and offshore Santa Ana winds for the surfers, while the spring sees more frequent onshore winds, making the surfing a bit more sporadic. Fall and spring are friendly on the pocket too, as hotel rates fall from summer peaks.

Overall, October is the best month to go to San Diego. It has excellent weather, fewer crowds, more affordable accommodation prices and cheaper flights. 

High Season: June to August

Best for experiencing the city's freewheeling spirit

Whoosh! Here comes a skateboarder. Splash! There goes a wet-suited surfer, board under arm. Overlooking the shore, there's a Chanel-clad diner lifting a dainty porcelain cup off its saucer. The city of San Diego and its coastal neighborhoods exude the kind of freewheeling spirit that brings out the best in people, and summer is the season to surrender to its siren song. 

The hot, dry months from June to August are the peak summer season in San Diego; temperatures and hotel rates soar, and it can get busy on the city's 60-plus beaches. Amidst the blue-sky weather, June often sees the cloudy skies referred to by Californians as "June Gloom." July could be considered the worst time to visit San Diego, as it’s the busiest and the most expensive month to visit. Kids are on summer break, crowds are dense and hotels fill up. But July also brings Pride celebrations, professional baseball and tons of summer programming like outdoor movie nights. It’s all about what you’re looking for. 

Low Season: November to February

Best for whale watching

Although it's far from cold, San Diego is slightly chillier in the winter months and there's a higher chance of rain. On the other hand, it's whale-watching season, so there are perks for the small inconvenience of bringing a warm layer. 

Gray whales pass San Diego from mid-December to late February on their way south to Baja California, and again in mid-March on their way back up to Alaskan waters. Their 12,000-mile round-trip journey is the longest migration of any mammal on earth, and you can spot them easily along the San Diego coast.

What is the cheapest month to visit San Diego?

October and November are the cheapest months to book a SoCal trip. You’ve got mild, comfortable weather (the temperature stays around 70°F) and fewer crowds. But, most importantly, you can enjoy bargain prices on accommodation and flights. As the majority of visitors go home from summer vacation, the hotels are getting cheaper and you can score deals. The only exception is Thanksgiving break in November, when the number of visitors soars. 

During the fall, you can profit from many free San Diego attractions and enjoy pleasant coastal hiking trails without the scorching summer heat. October is also the best month for visiting the iconic San Diego Zoo. Children under the age of 11 may when accompanied by a paid adult from October 1-31.

What is the rainy season in San Diego?

The rainy season in San Diego is from December to March. January is usually the wettest and coldest month of the year, but December and February don’t fall too far behind. Winter is definitely not a time for a beach holiday, as the ocean gets cold and unwelcoming. But it’s the best season for whale watching as thousands of gray whales embark on a migration journey to the breeding grounds starting in December.
