Best Times to Visit San Diego
The best times to visit San Diego are March through May and September through November. You can find some great deals on travel rates during the low seasons in comparison to the peak summer season. However, because of the warm weather, which averages about 60 to 70 degrees year-round, there's never really a terrible time to visit. But that doesn't necessarily mean sunny days abound as well. During the months of May and June, overcast days occur often, so much so that locals designate the months as "May Gray" and "June Gloom." And when it comes to rain, San Diego sees the most rainfall during the winter months, so a day at the beach is out of the question during this time (not to mention the ocean's waters are way too cold for swimming).

Spring is one of the best times to visit America's Finest City. The weather is mild (temperatures average in the mid-60s) and there are fewer visitors to share the streets and roads with compared to the summer. "May Gray" normally lives up to its name, so don't expect to see the sun all day every day throughout the month. If you're a fan of flowers though, this is the perfect time to visit. While San Diego isn't known as being a destination for flowers, the Coronado Flower Show (the largest tented flower show in the United States) is held during this time and the Carlsbad Flower Fields are in peak bloom.
This is everyone's favorite time to visit San Diego thanks to warm weather (average highs hover in the mid- to high 70s) and plenty of festivals. But vacationing this time of year could be problematic. "June Gloom" occurs yearly so if you're wanting nothing but sun, it's best to schedule your visit during the later part of summer. Come July, room rates are likely to spike, especially around Comic-Con, the city's biggest event. Comic-Con is so big, hotel rooms tend to be sold out months in advance, both downtown (where the event is held) and in the neighboring areas. August doesn't see as many visitors as July, but keep in mind it is still technically peak travel season in San Diego which will yield higher travel rates than other times of the year.
Autumn is a pretty sweet spot in San Diego tourism. Although tourists tend to linger well into September to soak up the last of the summer weather (average highs remain in the upper 70s), October and November see a drop in crowds as well as hotel rates. Foodies will want to visit during this time for the multiple culinary events held, including Restaurant Week in September.
Winter is the city's coolest season, but don't expect a traditional winter in San Diego. Average temperatures rest in the 60s and the lows drop into the high 40s, but that's only very late at night or in the early morning. If you're after a beach vacation, don't come during this time. While the temperatures don't reflect that of a real winter, rain showers can be frequent. Not only that, but the ocean's waters get so cold during this time, most locals don't bother braving the shores at all. On the other hand, hotel rates tend to be lower in the winter.
