San Diego in March is when we shift into spring mode. Hotel rates begin climbing around the second and third weeks as spring break demand kicks in, but the city still feels more relaxed than the peak summer months.
With NCAA March Madness games at Viejas Arena, the Cherry Blossom Festival, St. Patrick’s Day festivities, the Carlsbad Flower Fields in early bloom, and brand-new attractions opening at both the Safari Park and LEGOLAND California, there is no shortage of reasons to visit, whether you’re traveling with family, a partner, or on your own.
The information below will help you determine the best time to visit San Diego for you. Or, if you already have a trip booked, you should have a better idea of what to expect in March. I’ve included the month’s biggest events along with ideas for things to do around the county
San Diego Weather in March
San Diego weather in March signals the shift from winter to spring. The rain tapers off, days grow noticeably longer with daylight saving time, and temperatures begin their slow climb toward the warmth that defines our city. A light jacket is still necessary in the evenings, but you will start to see more sun-soaked afternoons that feel like a preview of summer.
March Weather at a Glance
- Ocean temperature: 58–61°F.
- Average temperature (high/low): 67°F/54°F
- Rainfall: 1.5 inches (average 4 rainy days)
- Days of sunshine: 70%
- Daylight: 12 hours
Our Microclimates: What to Know This Month
San Diego has four microclimates: coastal, inland valleys, mountains, and desert. March is when they start to feel genuinely different from one another as spring arrives unevenly across the county.
- Coastal: Mid-to-upper 60s most days, warming into the low 70s by late March. Mornings are still cool enough for a layer, but sunny afternoons increasingly feel like shorts weather. Neighborhoods like La Jolla, Coronado, Del Mar, and Downtown San Diego are where most visitors spend their time.
- Inland valleys: Daytime highs regularly reach the low 70s, making this a comfortable month for outdoor attractions in communities like Escondido and Ramona. Mornings run cooler than the coast because cold air settles into the valleys overnight, so plan for layers if you have early reservations at San Diego Zoo Safari Park.
- Mountains: Alpine and Julian are beautiful in March as the landscape greens up and early wildflowers appear, though mornings can still dip near freezing at higher elevations.
- Desert: This is peak season for Anza-Borrego Desert State Park. Daytime temperatures climb into the 80s, and if winter rains cooperate, the desert wildflower superbloom draws visitors from across the state. March is the month to go.
A tip: our local television stations give weather forecasts by microclimate, so if you enter “San Diego” on your weather app, it defaults to the coastal City of San Diego and may not reflect conditions where you’re actually headed. Enter the specific community instead — Escondido for Safari Park, Julian for the mountains, or Borrego Springs for the desert.
Looking at the weather in each microclimate will help you decide what to pack (layers).
What That Actually Feels Like
March in San Diego feels like a transition, and a welcome one. The cool, damp stretches of winter give way to consistently pleasant days, especially along the coast. You will see more people on the beaches in swimwear than in prior months, and outdoor dining feels comfortable well into the evening.
Rain is still possible in early March, but storms become less frequent as the month progresses. By mid-to-late March, most days are sunny, and the light has that particular California quality that makes everything look a bit more vivid. Daylight saving time also means longer evenings, which is ideal for sunset walks along the bluffs or post-dinner strolls through Little Italy.
The biggest variable in March is spring break. Depending on school calendars, you may notice a shift in energy around town starting mid-month, with more families at the theme parks and beaches. It’s still nowhere near summer crowds, but it is a noticeable uptick from February’s quieter pace.
Can You Go to the Beach in March?
San Diego beaches in March are noticeably livelier than in the winter months. As temperatures climb and daylight saving time extends the afternoons, you will see more families spreading out blankets, more surfers in the water, and more visitors taking advantage of the wide-open sand that summer crowds will eventually claim.
Spring Break Starts to Show
The shift happens around mid-March, when spring break begins for some school districts. Beaches like La Jolla Shores, Coronado, and Mission Beach pick up, particularly on warm afternoons.
Tourists wade into the water, sign up for surfing lessons, and kayak the La Jolla sea caves, and locals are increasingly joining them. Once the clocks spring forward, I enjoy taking the kids to the beach in the late afternoon to unwind and watch the sunset. Bring a picnic or grab a pizza for a picture-perfect early dinner on the sand.
Is It Warm Enough to Swim in the Ocean in March?
Ocean temperatures in March range from about 58°F to 61°F, which is a slight improvement over February but still cool enough that most people will want a wetsuit for anything beyond a quick splash. You will see visitors, especially kids, jumping in without one and having a great time, but for extended swimming, surfing, or paddleboarding, I still recommend a wetsuit.
You can rent wetsuits at surf shops and surfing schools around San Diego, and most carry kids’ sizes as well (call ahead for availability). If you are booking a surf lesson or kayak tour, wetsuits are typically included.
Advice for Booking Hotels in March
March is when San Diego hotel rates begin to climb toward peak season. The first half of the month still offers reasonable rates, but once spring break begins (typically mid-March through early April, depending on the school district), availability tightens, and prices rise in tourist areas.
Early March: Last of the Shoulder Season Rates
If your schedule is flexible, the first two weeks of March are a sweet spot. You will find rates closer to winter pricing, fewer crowds at restaurants and attractions, and better availability at popular San Diego hotels. This window is especially appealing for couples or adults traveling without kids who can avoid the school calendar entirely.
Mid-March Onward: Spring Break Demand
Hotel rates increase noticeably once spring break begins, and family-friendly room types like double queens and specialty suites book first. If you are planning a family trip during spring break, book as early as possible. Inventory for Easter week in particular tends to shrink quickly at San Diego resorts and beachfront hotels.
Katie’s Hotel Tips
If you are considering a spring break or summer San Diego, do not wait. Our hotels are already filling up and family room types sell out months in advance. I’m happy to help with room selections and can often secure upgrades or added perks through my hotel partnerships. Hotel del Coronado is our most popular spring break and summer hotel.

Take a Day Trip to See Desert Bloom
Desert bloom takes place in Anza-Borrego Desert State Park, about 90 minutes from San Diego. If you’ve never seen it, you’ll be pleasantly surprised at the millions of colorful wildflowers that carpet the desert floor. Some years are better than others depending on winter rains, but you’ll rarely be disappointed.
The best time to see the desert bloom is from late February through early April, with the second week of March often considered peak time. The Anza-Borrego Foundation posts updates on what’s in bloom, directions, and what to know before you go.
Look for Baby Seals
It’s still pupping season at Children’s Pool Beach in La Jolla. While the beach is closed, you can still see the babies from the boardwalk. Read my guide on how to see the La Jolla seals.
Check Our Tide Pools
March is one of the last months with minus tides during daylight hours. Check the tide charts.
Afternoon minus tides are happening in March, so use this as a chance to go out and safely explore. Pair a visit to the La Jolla tide pools with a stop at the Children’s Pool seal rookery.
Go Grunion Running
March is one of the best months for grunion running because the runs happen at reasonable evening hours (around 9:30-11 p.m.) rather than the midnight timing you’ll find in other months.
Grab your headlamp and head to the beach to watch these silvery fish spawn on the sand. It’s really fun to do with friends. Check the calendar of expected runs.

It’s nearing the end of the season, but you can still go gray whale watching in San Diego on boat tours, for what will be a lovely way to spend a half-day outside.
The whales have headed back north with their calves further away from the shore, so your best chance of seeing them is on a boat tour.

Your San Diego packing list for March includes sweaters, long-sleeved T-shirts, jeans, and jackets among other things.
Pack in layers to handle the temperature swings between morning fog and afternoon sun. Here’s what to put in your suitcase:
- Light-weight jacket for the afternoons and evenings
- Athleisure (a San Diego wardrobe staple)
- Hiking shoes for trails
- Portable umbrella (optional)
- Bathing suit and warmer cover-up
- Rashguard or UV shirt for sun protection and warmth
- Sunscreen
- Sunglasses
- Hat for sun protection
- Flip flops for the beach and pool
- Shorts for beachgoing

Even though I said it might rain here in March, you don’t need to pack a raincoat if you don’t have one. Many San Diegans don’t even own them.
Lifestyle: What Residents Are up To
Locals are planning staycations and road trips for spring break, and honestly, we’re checking out a lot of the same things on this list. March is when San Diegans remember why we live here. The weather is perfect, the days are getting longer, and we’re not fighting summer tourist crowds yet.
We’re taking advantage of the comfortable temperatures for hiking and beach days, planning visits to new attractions before the lines get long, and soaking up those afternoon hours that are finally extending past 6 pm. Spring break means we’re looking for things to do, too.
