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

January in San Diego kicks off with Restaurant Week, peak gray whale migration, and some of the lowest hotel rates of the year. With Monster Jam roaring through Snapdragon Stadium, the PGA Tour returning to Torrey Pines, and SeaWorld’s Inside Look weekends, there’s no shortage of things to do, even in our quietest month.

January is the kind of winter weather that people from cold-weather climates fly in to enjoy, with an average high of 65°F, blue skies, and only scattered showers. With the holiday peak season over, it’s the perfect time to visit San Diego for a crowd-free experience at excellent prices.

The information below will help you determine the best time to visit San Diego for you. Or, if you have a trip booked, you should have a better idea of what to expect in January.

I’ve included January events around the county, along with some fun ideas for things to do.

San Diego January Weather

San Diego weather in January is our version of winter, and it’s mild compared to most of the country. You can pretty much count on a mix of sunny days with blue skies and some scattered showers. If you’re trying to decide what to pack or plan, here’s what you can expect.

Our Microclimates: What to Know This Month

San Diego’s famous microclimates, which include coast, inland valleys, mountains, and desert, behave a little differently depending on the time of year. In January, here’s what you can generally expect:

• Coastal: Mild days in the mid-60s with cool mornings and evenings. Most sunny days feel comfortable in a light jacket or long sleeves. This includes major tourist areas like La Jolla, Downtown, and the beaches.
• Inland valleys: Colder mornings, sometimes frigid from December through February, because cold air sinks into the valleys. Communities like Escondido, where the San Diego Zoo Safari Park is, can warm into the upper 60s on sunny afternoons.
• Mountains: Cold with possible snow during major storms. Julian and Palomar Mountain are popular day trips for residents who want to see the seasons change since we don’t experience that along the coast.
• Desert: Cool mornings but warmer days. Anza-Borrego is comfortable for hiking this time of year, though the famous wildflower bloom is still weeks away.

If you’re staying coastal (as most visitors do), the forecast there will give you the most accurate sense of what to expect day-to-day.

What That Actually Feels Like

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. January in San Diego often surprises visitors with how pleasant it is. While the rest of the country deals with snow and freezing temperatures, we’re walking the beach in light layers and dining outdoors. You will see people in shorts on sunny afternoons, though mornings and evenings require a jacket.

Rain is possible, but we typically don’t get a ton of it. We renovated our backyard a few Januarys ago, so I was paying close attention, and it only drizzled twice that month. Last year, it only rained heavily a few times. When it does rain, storms usually pass within a day or two, and many locals use it as a good excuse to visit indoor attractions and Balboa Park museums.

The biggest January surprise? Those rare warm spells. Every few years, we get a stretch of 70°F+ days that feels like early spring arrived ahead of schedule. It’s unpredictable, but when it happens, it reminds residents why we’re lucky to live here.

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.

A Peaceful Coastline

San Diego beaches in January offer wide open sand and easy parking, especially on weekdays. Maybe it’s the crisp San Diego weather in January, but the stunning sunsets at the beach are particularly beautiful. It’s a lovely time for beach photography, sunset watching, or simply enjoying the coastal views without the summer crowds.

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.

Is It Warm Enough to Swim in the Ocean in January?

The Pacific Ocean is cold in January. There’s no getting around it. Ocean temperatures hover around 58-60°F, so 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.

That said, you CAN and should still take surfing lessons or learn how to stand-up paddleboard. Both fulfill any exercise-related New Year’s resolutions, and instructors provide wetsuits as part of the lesson.

Advice for Booking Hotels

Advice for Booking Hotels in January

January is a GREAT time to stay in San Diego hotels. With the holiday peak season over, rates drop to their lowest point of the year, and you’ll get the most bang for your buck for sightseeing and outdoor activities.

New Year’s Week: Winding Down from Peak Season

The first few days of January still carry holiday pricing as winter break wraps up. By the second week, rates drop significantly across the board. If your dates are flexible, arriving after January 5 or so will save you money at nearly every property.

Mid-January Through Month’s End: The Best Rates of the Year

From the end of winter break through the rest of the month, hotel rates are at their lowest point of the year. MLK weekend may see a slight uptick, but nothing compared to summer or holiday pricing.

This is an ideal time for visitors who want quality experiences without peak-season prices. Plus, it’s less hot than 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. San Diego in winter is so pleasant on a sunny day (like today as I’m typing this).

Katie’s Hotel Tips

If you book a flexible rate through the hotel and you see the rate drop, the hotels can usually modify your reservation to the lower rate. Or, you can cancel and rebook. January is also an excellent time to grab lower summer and spring break rates before they rise.

I’m stepping in here to say that if you’re thinking of coming to San Diego during spring break or summer of 2026, please book your trip now. Our hotels are already booking up for popular dates. January’s lower rates won’t last forever.

Please note that beach valet services may be limited in January. You can ask me or call the hotel in advance to confirm availability.

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.

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!
