San Diego in January: Weather, Events, Things to Do, & Insider Tips

One thing that is consistent about San Diego in January is the weather. You can pretty much be sure of a mix of sunny with blue skies with some scattered showers during this month.

It’s the kind of winter weather that people from cold weather climates and frigid temps fly in to enjoy (hello, average high temperature of 65F).

In fact, with the holiday peak season over, January is the perfect time to visit San Diego for a crowd-free experience with excellent weather conditions.

San Diego January Weather

San Diego weather in January is a mix of crisp air and sunshine. If you didn’t know it, you’d think that some of the photos I’m about to show you were taken in the summer.

Our Microclimates

San Diego has four main microclimates: coastal, inland valleys, mountains, and desert — in that order.

Along the coast, we have a pretty temperate climate with the most humidity, thanks to the ocean. Inland valley communities like Escondido, where the San Diego Zoo Safari Park is, will have colder mornings (it can be frigid there from December–February) because cold air sinks into the valleys. Mountains may see snow if there’s a big storm, and the deserts also have cool mornings but warmer days.

Most tourists will stay in the coastal region, along the beach neighborhoods like ever popular La Jolla, and perhaps venture into the inland valleys to golf, taste wine, or visit the Safari Park.

Residents, however, take San Diego day trips to the mountains. This is because we don’t see the seasons change along the coast.

Blue Skies in Winter

You’d think San Diego in winter would receive a ton of rain in January, but we typically don’t. In fact, we renovated our backyard a few Januarys ago, so I was in tune with the rain. It only drizzled two times briefly that month. Often, in January last year, it only rained heavily a few times.

Here are the San Diego January weather stats:

• Average temperature (high/low): 66°F/50°F
• Average rainfall: 2 inches
• Days of rain: 7
• Days of sunshine: 72%
• Daylight: 10.2 hours
• Ocean average water temperature (high/low): 60.3°F/58.1°F
• Average wind speed: 6 mph

Can You Go to the Beach in January?

Of course, you can go to beaches in San Diego in January.

You will find more people than in December on the beach exercising and surfing at popular spots like Ocean Beach, and all along the San Diego waterfront.

Maybe it’s the crisp San Diego weather in January, but the stunning sunsets at the beach are particularly beautiful. I took this photo below last January from Crystal Pier in Pacific Beach.

Ocean Tips

The Pacific Ocean is cold in January. There’s no getting around it. The hearty will be fine for a quick swim, but you’ll need a wetsuit otherwise. You can rent them at various surf shops around town, even for kids.

You CAN still take surfing lessons or learn how to stand-up paddleboard. Both fulfill any exercise-related New Year’s resolutions.

Advice for Booking Hotels

January is a GREAT time to stay in San Diego hotels. From the end of winter break to President’s Day weekend, rates are at their lowest point of the year.

If you are visiting to sightsee or take advantage of the many outdoor activities in San Diego, you will get the most bang for your buck if you come in this low season.

Plus, it’s less hot than it is in the summertime. I love walking around San Diego Zoo, downtown San Diego, and Balboa Park in January. San Diego in winter is so pleasant on a sunny day (like today as I’m typing this).

Please note that beach valet services may be limited in January, but you can ask me or call the hotel in advance to see if they are available.

Or, Start a New Year by Rejuvenating at Our Destination Spas

Did you know that some of the best destination spas in the world are right here in San Diego? If you’re looking to invest in some rest and relaxation time – with a luxury wellness element – what better way to do so than with a Destination Spa visit to San Diego in January? 

I can tell you from personal experience that you feel better when you return home.

There’s no better way to kick off a new year than by rejuvenating at Golden Door or Rancho La Puerta (just across the Tecate, Mexico border) for a week (they also offer shorter stays). Through me, you have access to benefits at both of these San Diego spots. I can also book you into Cal-a-Vie.

Or, I would recommend a weekend at Rancho Valencia. It’s a Relais & Chateaux property, which means the food is outstanding, but you can also take advantage of their many wellness offerings. They typically have a long roster of fitness classes, a yoga pavilion, a Pilates studio, and tennis and sports courts.

San Diego January Events in 2025

San Diego events in January are typically lighter in comparison to the rest of the year, but there are still plenty of annual events to attend. 

Farmers Insurance Open

Golfers and spectators look forward to the Farmers Insurance Open PGA tournament every year at the end of January at San Diego’s Torrey Pines Golf Course. For 2025, the dates are January 22-25.

(You can watch from home and get a feel for what our weather is like in January. The course itself is gorgeous.)

Of course, the center of the action is at my favorite La Jolla hotel, The Lodge at Torrey Pines, which overlooks the course. It’s tough (if not impossible) to secure reservations near and during the tournament, but it sure doesn’t hurt to try.

Jurassic Quest at Del Mar Fairgrounds

The nation’s largest touring dinosaur exhibit comes to San Diego thanks to Jurassic Quest.

From adorable baby dinos to a fierce T-Rex, guests embark on the adventure of a lifetime at Del Mar Fairgrounds led by a thrilling-for-all-ages audio tour as they view all kinds of photorealistic dinosaurs that move and make sounds, all from the comfort of their own vehicles.

Things to Do in San Diego in January

We love outdoor activities year-round in San Diego. There are many ways to fulfill a New Year’s resolution involving health and wellness – often for free (tip: Balboa Park is a favorite!).

Plus, I challenge you to add this to your resolution or to-do list: try something new in San Diego this year.

Go Tide Pooling

I know I sound like a broken record, but you should visit our best San Diego tide pools. The afternoon minus tides vary during the month of January, so be sure to check the online tide charts.

Recently I walked the tide pools in La Jolla along the La Jolla seal trail, roughly between La Jolla Cove and Children’s Pool Beach.

Many people were not practicing the best tide pool etiquette, so please be mindful that you’re not one of them. You can take shells from these areas, but please remember that the animals in the tide pools use them for their habitats.

You can’t take shells from tide pools in the protected La Jolla Ecological Reserve (around La Jolla Cove).

Visit San Diego Botanic Garden

I highly recommend a walk or day out with the kids at the San Diego Botanic Garden. You can clock in some serious steps on the 4 miles of trails, get garden inspiration, and let the kids safely play outside in the Hamilton Children’s Garden (and learn about plants and the environment).

Visit Outdoor Shopping Areas and Malls

Check out retailers in Westfield UTC mall or shops in the Village of La Jolla, Cedros Avenue in Solana Beach, North Park, and more.

Go Gray Whale Watching

It’s officially whale watching season in San Diego! And there are many whale watching tours to choose from.

If you’re not comfortable heading out to sea on a whale watching tour, you can try viewing from land. This is the month when they swim south to Mexico to give birth. So, they swim closer to shore, making January the ideal time for whale watching in San Diego.

When they swim back north with their calves, they tend to swim in deeper water further out to feeding grounds.

Popular places to try to see them from land include:

• Whale Point at Cabrillo National Monument
• Torrey Pines State Natural Reserve
• Various cliffs (Sunset Cliffs is a good choice) and piers — just keep an eye out for spouts

Take Your Dog on an Adventure

Take your dog to off-leash and on-leash dog beaches in San Diego.

We like Law Street Beach in Pacific Beach, but there’s also North Beach in Coronado, Del Mar Dog Beach, and other on-leash options. Just check to be sure you go when dogs are allowed and what the leash requirements are.

You can also look at my list of things to do with dogs in San Diego.

What to Wear in San Diego in January

What to pack for San Diego in January involves sweaters, long-sleeved T-shirts, and a medium-weight jacket if you plan to be out in the evenings.

Here’s what to put in your suitcase:

• Medium-weight jacket for the evenings (I wear a Lululemon puffer jacket in later afternoons and evenings)
• Athleisure and hiking shoes for outdoor activities
• Portable umbrella
• Bathing suit and warmer cover-up
• Rashguard or UV shirt for sun protection and warmth
• Sunglasses
• Sunscreen
• Hat
• Flip flops for the beach and pool (it is San Diego in January!)
• Shorts for beachgoing
• T-Shirts (mostly long-sleeved)
• Pants or jeans
• Sweaters or sweatshirts
• Comfortable walking shoes for sightseeing
• Casual wool/warm dress or collared shirt, sweater, and nice jeans (if you plan to dine in one of our nicer restaurants)
• Sweaters and sweatshirts
• Ugg boots (residents are wearing them — I’m wearing them daily around the house and sometimes out)
• Wetsuit, if you have one (otherwise they’re easy to rent)

Real fur is not well-received in Southern California, so leave it at home.

San Diego Lifestyle: What Residents Are Up To

Exercise and wellness are top of mind after a busy holiday season. But most of us are home planning for the new year, with occasional excursions to the beaches, restaurants, and other attractions.

I can also tell you firsthand that it’s been a BUSY month of vacation planning, whether you’re planning a trip to San Diego or elsewhere. People are buying theme park tickets to use six months down the road (probably to be sure pricing stays the same in an inflationary environment and also for budgeting purposes).

If you are traveling this year, plan now. If you live here, please share your thoughts about San Diego in January!
