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

October in San Diego is a month that is packed with fun family events. Popular Halloween festivities include events where kids can safely trick-or-treat, dress up in costumes, or at least see some decor.

If you’re thinking of planning a San Diego family vacation in October, I would highly encourage it. A major reason is not only that, yes, we still have beautiful beach weather, but we also have Kids Free San Diego all month long.

I’ve included more details below, but in a nutshell, with Kids Free San Diego, children 12 and under get free admission to most of San Diego’s attractions with a paid adult. LEGOLAND California, SeaWorld San Diego, Belmont Park, the museums at Balboa Park, and much more are all on the list.

This month-by-month series aims to help you decide when the best time to visit San Diego is for you. For residents, I add in tidbits about what’s happening around down.

San Diego October Weather

San Diego weather in October is when the change of seasons is the most noticeable to residents. This usually occurs mid-month. (It’s barely a noticeable change for those of you coming from the East Coast and similar climates.)

San Diego in September can be hot and dry in stretches. It’s been a little humid even in September 2025. The days have been sunny and this pattern typically bleeds into the first 2-3 weeks of October.

In recent years, early October has even experienced heatwaves, with temperatures reaching the mid-90s inland and low 80s on the coast.

During October, the days grow shorter, and the air feels crisper in the morning and in the evenings. It’s still shorts weather during the day for the most part.

Our Microclimates

San Diego weather in October that matters to you depends on which of our four microclimates you’ll be in the most. These include coastal regions, inland valleys, mountains, and the desert.

San Diego beaches and most of our major resorts are located in the coastal regions.

It’s Still Sunny in October

We usually have hot and dry Santa Ana winds for stretches of several days in a row or a bit longer. Temperatures spike during these days, and so does the risk of wildfires across the state. It’s important to stay hydrated and moisturize during Santa Anas.

You will notice that the days slowly get shorter, and the ocean temperature also cools down. It cools only by a degree or two from September averages, but you will feel it.

For those of you who like weather stats, here they are for October:

• Average temperature (high/low): 74°F/61°F
• Rainfall: .5 inches
• Days of sunshine: 68%
• Daylight: 11.5 hours
• Ocean temperature (high/low): 66.4°F/63.5°F

If you plan to visit San Diego in October, try coming during the first few weeks. The odds of capturing sunny beach days are higher during this timeframe but certainly not impossible for the rest of the month. There will be days of partial sun and some cloud cover.

What the Beach Is Like

San Diego beaches are less crowded overall in October. In fact, during the week, they’re downright mellow.

You’ll still struggle to find parking on sunny weekends, though. They’ll be busier during the hot and dry Santa Ana winds but not as crowded as they are during peak summer weekends.

Take this opportunity to choose a beach that’s new to you if you’re a local. If you’re a tourist, you don’t need to stress about crowds on the sand at the popular beaches.

Ocean Tips

Locals still swim in the ocean with no problem during the first week or so of October. You can and absolutely should still book snorkeling tours and surfing lessons. I would definitely plan to rent a wetsuit for either activity.

Advice for Booking Hotels in October

If you book early, October is typically when San Diego hotel rates reach moderate levels. However, don’t be surprised to encounter sold-out weekends or price spikes on odd dates as hotels reach full occupancy.

With many Halloween-themed activities popping up all over SoCal, it’s important to acknowledge the higher volume of tourists who might show up for their favorite haunts. It won’t be as packed as, say, Labor Day weekend, but October may still be a bit crowded.

The one thing to check is how a hotel’s beach offerings may be modified. Some beach valet services (shuttles to the beach, chair set-up at the beach, etc.) may pause in the shoulder and low seasons.

If you are visiting San Diego with kids, October is fantastic. Kids stay free anyway at most hotels that I work with. But, many San Diego hotels offer various special gifts or ‘kids eat free’ promotions during Kids Free October. You also may need to print a voucher or buy special kids free tickets but it’s huge savings for families.

To give you an idea, here are a few examples:

• Catamaran Resort Hotel & Spa: One kids’ meal is free for ages 12 and under with each paid adult entree at Oceana Coastal Kitchen. You’ll also receive one complimentary paddleboard or kayak rental with the purchase of one adult one-hour or longer paddleboard or kayak rental from the onsite Action Sports Rentals.
• San Diego Mission Bay Resort: The kids free October package includes complimentary parking and a $50 resort credit plus a kid-friendly amenity.
• Kids checking into the newly renovated Sheraton San Diego Hotel and Marina can enjoy a kid’s scavenger hunt with a complimentary gelato for children 12 and under.
• Kids also eat free at Kings Inn’s Waffle Spot or Amigo Spot.

And there are many, many more. If you’re considering coming in a future year, note that promotions for this annual event typically aren’t set until between August and October.

San Diego October Events

San Diego events in October typically focus on Halloween and Kids Free San Diego.

Kids Free October San Diego

Kids eat and play for free at almost every leading San Diego attraction you can think of during this fantastic promotion.

The annual event is one of the best ways for residents and visiting families to save money in San Diego. Families can save hundreds of dollars by taking advantage of this amazing offer, which includes over 50 museums, plus major attractions like LEGOLAND California, San Diego Zoo and Safari Park, SeaWorld San Diego, and the Birch Aquarium.

You’ll need to check with the specific venue or on the San Diego Tourism website, of which I am a member, to see what terms and restrictions apply. Typically the promotion applies to kids ages 12 and under, but it can be for ages 9 and under. As already mentioned, you might also need to print a voucher.

San Diego Zoo Halgloween

Weekends in October are filled with glow-in-the-dark fun, performances, and grins at San Diego Zoo. Halgloween happens on Fridays, Saturdays, and Sundays in October between 5–9 p.m. 

In addition to live music, acrobatic performances, and interactive games, the whole family can jump in a bubble dance party,  check out Dr. Zoolittle’s tips and tricks, and jam to a mariachi band.

And, because it’s October, up to four kids ages 11 and under are FREE! Kids are encouraged to attend in their favorite costumes. Admission to Halgloween is included with San Diego Zoo admission, which you can save on with my promo code.

Autumn Festival at San Diego Zoo Safari Park

On Saturdays and Sundays in October, guests at San Diego Zoo Safari Park are treated to special Autumn Festival activities that include live bluegrass music, interactive characters, and a chance to learn about the animals and plants that thrive during the fall season.

You’ll be able to taste fall, too, with the likes of pumpkin-flavored drinks (even beer), apple dishes, and more seasonal delights to eat and drink.

SeaWorld San Diego Spooktacular and Howl-O-Scream

There are two SeaWorld San Diego Halloween events to enjoy this year. The first is the family-friendly daytimg Spooktacular, and the second is the scarier Howl-O-Scream catered toward older kids and adults after dark.

Family-Friendly Fun: SeaWorld Spooktacular

The Spooktacular event transforms the park into a pirate-themed Halloween adventure perfect for younger children.

After-Dark Frights: Howl-O-Scream

When the sun goes down, the terror awakens. Howl-O-Scream is a separately ticketed event that turns the park into a landscape of fear.

• What to Expect: Navigate through terrifying haunted houses and scare zones, ride your favorite coasters in the dark, and visit sinister-themed cocktail bars.
• Dates: Select nights between September 12 – November 1, 2025.
• Best For: Teens and adults. I do not at all recommend this event for young children.
• Cost: Requires a separate ticket. Howl-O-Scream is not included with regular park admission, Annual Passes, or Fun Cards.
• Good to Know: The event officially starts at 7 p.m., but your ticket allows for early entry starting at 6 p.m.

Things to Do in San Diego in October

Things to do in San Diego in October that are worth considering include the below!

See San Diego’s Spooky Side

You can check into one of our haunted hotels in San Diego, like Hotel del Coronado or Grand Colonial La Jolla.

Take a self-guided tour through The Whaley House, arguably San Diego’s most haunted house in Old Town — where you can also walk through El Campo Santo cemetery.

Spend a spooky night camping out with Lions, Tigers & Bears!

Book the Old Town Trolley’s Ghost and Gravestones tour in the evening. It takes you to many of our spookiest sites and runs nightly. Check the schedule to book.

Celebrate Dia de los Muertos 

The Day of the Dead celebrations are happening all over San Diego, so catch one of these to celebrate and honor lost loved ones. 

Go to Bates Nut Farm

One place to enjoy fall with the family is Bates Nut Farm. Their pumpkin patch is open from September 18–October 31 in 2025 and it’s well worth a visit.

They’re hosting their usual Halloween events, including the scarecrow contest and dog costume contest, and you can enjoy hay rides, pony rides, and a petting zoo. There’s even a mechanical bull if you’re brave enough!

Go to a Pumpkin Patch

It may be warm in San Diego, but our pumpkins still withstand the heat. There are several pumpkin patches that your whole family will love.

Pumpkin Stations are always favorites. The Del Mar location is by the racetrack and offers many great fair rides for the little kids, train rides, giant inflatable slides, a petting zoo, a Ferris wheel, and much more.

Carlsbad Strawberry Company’s pumpkin patch is another family favorite thanks to its petting zoo, tractor rides, corn maze (there’s also a Haunted Corn Maze in the evenings for older kids and adults), and more.

Go Apple Picking in Julian

U-Pick apple orchards in Julian are open for the season. Check with the U-Pick orchards directly for opening hours. Enjoy some fresh apple pie and other fun things to do in Julian, CA.

What to Wear in San Diego in October

I realize I sound like a broken record if you’re reading my other San Diego by month posts. What to pack for San Diego in October includes layers. You’ll probably pack more pants and sweaters than you would in our summer months for evenings.

The packing list is similar to September:

• Bathing suit
• Rashguard or UV shirt for sun protection
• Sunglasses
• Sunscreen
• Hat
• Flip flops
• Bathing suit cover-up
• Shorts
• T-Shirts (short-sleeved and long-sleeved)
• Tank tops for pool, beach, and hot weather days
• Pants or jeans
• Sweater or jacket for evenings
• Comfortable walking shoes for sightseeing
• Casual dress or collared shirt and nice jeans (only if you plan to dine in one of our nicer restaurants )
• Moisturizer if you’re here during Santa Ana winds
• Wetsuit, if you have one (otherwise they’re easy to rent)

Lifestyle: What Residents Are up To

We are gearing up for Halloween and festive decor around neighborhoods is starting to roll out. Our kids love Halloween events across San Diego at the theme parks, so we’re going to them, too.

There are so many unique experiences in San Diego in October. For example, it’s hard to find a Dia De Los Muertos celebration anywhere else in the United States that’s quite like ours.

Plus, our restaurants are still perfect for outdoor and indoor dining. It’s a great idea to soak up the sun for as long as possible before it gets chillier, like San Diego in November.
