San Diego: Land of Perpetual Sunshine (Except for Those Other Times...)

Ah, San Diego. The land of beaches, burritos, and...brrr...occasional chills? That's right, folks, even paradise has its off days. But fear not, sun-worshippers! While San Diego isn't exactly known for its bone-chattering winters, it does surprise you with a little dip in temperature now and then.

So, How Cold Does it Get in San Diego, Really?

Usually not that cold. San Diego boasts a glorious Mediterranean climate, which basically translates to warm, dry summers and mild, wet winters. The average low in the coldest month (January) is a balmy 48°F (that's a cool 9°C for our international friends).

But hey, there are exceptions! Every once in a blue moon (or perhaps a rogue Santa Ana wind), San Diego can experience a brief cold snap. We're talking lows dipping down into the 40s (brrr!), maybe even the high 30s (prepare for goosebumps!).

Don't expect a polar vortex in July. San Diego's coldest days typically occur between December and February. But even then, it's usually just a few nights here and there.

Pro tip: If you're planning a winter trip to San Diego, pack a light jacket for evenings, just in case. But leave the parka at home; you'll probably end up using it as a pillow.
