Best Times to Visit San Diego
The best times to visit San Diego are March through May and September through November. Because there aren't as many school breaks during these seasons, you're more likely to avoid the throngs of families rushing to the San Diego Zoo. You can also find some great deals on hotel rooms during the winter when the rainy season hits. However, because of the abundance of sunny days, there's never really a bad time to visit. Just make sure to book in advance if you're planning a trip for the summer high season.
Early spring is one of the best times in America's Finest City. The weather is mild (temperatures average in the mid-60s) and the kids are still in school. As the temperature rises (nearing the 70s in May), you can expect a larger influx of tourists, causing room rates to increase. If you plan on visiting toward the season end, it's a good idea to book a few weeks in advance.
This is everyone's favorite time to visit San Diego thanks to warm weather (average temperatures hover in the high 70s) and plenty of festivals. But vacationing on a budget could be problematic this time of year. Crowds flood the major attractions — causing unreasonably long lines — and snatch up any available hotel rooms, which drives prices up. Make sure to book at least a month in advance.
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. To visit in early fall you'll probably need to make reservations several weeks in advance. But if you're planning for a late October or early November trip, a few days notice should be fine.
Winter marks the coolest and rainiest season, with temperatures resting in the mid-60s. And although the weather tends to deter beachgoers, this is a great time to be in Southern California. More frequent rain showers turn the landscape lush and vibrantly green, and hotel rates have a tendency to drop. This is also whale migration season, so you'll spot plenty of activity happening in and around the bay (when the fog clears). However, because of wintertime events, you should probably book a few weeks in advance, just in case.
