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

Frequently asked questions that I receive — since I live here and help people plan San Diego vacations — are about what it’s like in San Diego during certain months of the year. July is the height of summer in San Diego so a glorious month for weather, events, and things to do.

Various parts of the city host summer concerts and there are so many fun events to dress up or dress down for. Mission Bay is particularly beautiful at this time of year and it’s a great waterfront park to head for a family picnic.

My goal is to share what it feels like to be outside in our beautiful city, how we dress, and even what we locals are up to so that you can visualize and plan for the San Diego July lifestyle.

San Diego July Weather

San Diego July is pretty awesome with a few caveats. Let me tell you what that actually means.

A Note About Microclimates

Microclimates in San Diego include coastal regions, inland valleys, mountains, and the desert. San Diego weather in July that you care about depends on where in the county you’re headed to.

Most visitors are concerned about the weather in the coastal regions because they’re here to enjoy the beach. The best San Diego resorts and the San Diego International Airport are located in this microclimate as well. As a result, when you see average temperatures for San Diego, they’re talking about mostly the coastal regions though our local meteorologists will provide forecasts for all microclimates separately.

Occasional June Gloom Spill Over

We have coastal fog that we (not-so-) lovingly call May Gray and June Gloom in, you guessed it, May and June. It disappears if you drive a mile or five inland and sometimes it burns off along the coast in the afternoon (but not always). If you’re a beachgoer or staying in beachfront San Diego hotels, this weather phenomenon impacts you.

We’re talking about San Diego weather in July so why does this matter? June Gloom has been known to carry over into the first week of July. Yes, July 4th is occasionally celebrated under a marine layer. Does this dampen the festivities? Absolutely not. A few may skip the beach but rest assured the holiday is still quite the to-do.

Also, the cloudy skies don’t mean that you need to bundle up. We still wear shorts. Kids plow into the ocean without thinking twice. Sunglasses and sunscreen are must-haves.

Sunny Skies Otherwise

When we see June Gloom break and normal summer weather surface, all of a sudden the sun is mostly out in full force with a cloudy morning or day sprinkled in here and there. It’s just glorious and why my husband refuses to travel in mid-July through August because you can’t beat the beaches and summer weather in La Jolla.

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

• Average temperature (high/low): 76°F/66°F
• Rainfall: .03 inches
• Days of sunshine: 68%
• Daylight: 14 hours
• Ocean temperature (high/low): 65.4°F/68.5°F

What the Beach Is Like

The days surrounding July 4th are the busiest of the year at San Diego beaches, maybe tied with Labor Day weekend and to an ever-so-slightly lesser degree, Memorial Day weekend.

Tourist season escalates in July. Locals also save up their beachgoing until June Gloom blows over so we’re at the beach in July, too.

Does it mean you won’t find space for your chairs and umbrella? Absolutely not. Choose one of the beaches with lots of sand like La Jolla Shores Beach, Pacific Beach (especially at Law Street on the north side), Mission Beach, or Coronado Central Beach. Even with today’s need to distance, you can find space even on the busiest days, though arriving early is advised for parking reasons.

The same can’t be said on the smaller beaches like Windansea. These gems can be jammed with people on peak days but some sunbathers and surfers don’t mind this at all.

Ocean Tips

In July, you can shed your wetsuit unless you plan to go scuba diving or take a snorkeling tour. Long periods of time spent in Southern California ocean water require wetsuits at any time of the year. Surfers wear full or spring suits depending on the time of day and length of time in the water. If you or your kids enroll in any of the San Diego surfing schools, you’ll likely be given or asked to rent a wetsuit. They provide a little buoyancy, too.

High Hotel Occupancy

If you’re planning to stay in a San Diego hotel in July, book as soon as possible because hotels sell out. In normal times, summer rates increase closer to the date. I can’t tell you how many people I speak with, even now, who wait too long only to find their preferred room or hotel completely sold out.

Readers who book my portfolio of hotels are entitled to room upgrades subject to availability at check-in. In July and August, these upgrades (even with my volume and ability to give you VIP status) are hard to come by. So, if you’re visiting San Diego during the summer, book the hotel room that you want. Don’t rely on upgrades.

San Diego July Events

Seasonal San Diego events draw people from all over the country, which also helps explain why our hotels sell out.

Big Bay Boom (4th July)

The spectacular fireworks show over San Diego Bay that is coordinated to music played on local radio stations is a very big deal and can be seen from across the County.

The fireworks begin at 9pm and are released from four barge boats on the bay. Other smaller fireworks shows happen across the county but people plan in advance to be somewhere to see it on July 4 whether dining reservations, securing a spot on the Embarcadero, or booking a San Diego Airport hotel or downtown San Diego hotel with a view. Other great viewing points are Shelter Island, Coronado Ferry Landing, or Harbor Island.

Comic-Con

Arguably the largest event in San Diego is Comic-Con at the San Diego Convention Center. Tickets for this comic and arts extravaganza sell out within minutes. There’s something for all ages and the celebrity guest line up is always impressive.

If you’re lucky enough to snag a ticket or would like to experience the surrounding festivities, book your hotel room as soon as possible. A year in advance isn’t unreasonable, otherwise, you’ll be subject to peak pricing like you’ve never experienced.

Downtown San Diego hotels sell out way in advance during Comic-Con International and the days leading up to and following it. This means that guests spill over into Mission Valley, Coronado, La Jolla, and even further north which causes rates to skyrocket in other neighborhoods.

2024 Dates: Comic-Con runs from 25-28 July.

San Diego County Fair

Things to do in San Diego in July before Comic-Con include the San Diego County Fair which typically runs between Memorial Day weekend and July 4th weekend. Here, you’ll enjoy your “fair” share of gluttonous food from fried Oreos to fried Kool-Aid in addition to plenty of carnival rides and a concert line up full of big names.

2024 Dates: The County Fair runs from June 12 through July 7.

Del Mar Racing Season

Mid-end of July also marks the start of Del Mar Thoroughbred Club’s summer horse racing season. People come from all over to place bets on their favorite horses and jockeys at the Del Mar racetrack. During racing season, Del Mar hotel rates skyrocket.

There are all kinds of fun events during the season, both on and off the track. From a Hat Contest to various party events, and even a Beer Festival. Check their calendar for details.

2024 Dates: The Del Mar racing season runs from July 20 through September 8.

Point Loma Summer Concerts

This popular community tradition at Point Loma Park kicks off in July and it’s a great family-friendly option. The park has been hosting a summer season of concerts since 2001 and they always have a great line-up of mostly cover bands. Concerts are held on Friday evenings from July 12 through August 9.

Admission is free and the nearby All Souls’ Episcopal Church offers free parking and a shuttle to the festivities.

Sip of Julian

This quaint country town 60 miles north west of downtown San Diego is always worth a visit. With its olde world town hall and beautiful main street lined with pie shops, homey restaurants and excellent gift stores, Julian is fun for all the family.

For the past eight years the town has hosted Sip of Julian, during which local wineries, cideries and breweries serve up free samples in their tasting rooms. You can also sip on craft cocktails and small bites are on hand for purchase at most locations.

The event is held on July 27th this year. Just buy a ticket and visit the participating vendors whenever you like between 11 a.m. and 5 p.m. Proceeds from Sip of Julian fund the town’s Annual Country Christmas and Tree Lighting Celebration.

Marine Band San Diego Summer Concert

Honoring San Diego’s strong military association, the Marine Band San Diego Summer Concert is a fun-filled celebration of some of our most talented Marine musicians.

The popular band is called ‘Sound Strike’ and you can expect a rousing performance. The concert takes place on July 13th from 7 p.m. at the new Piazza della Famiglia (W. Date Street between India & Columbia Streets), and is hosted by the Little Italy Association of San Diego.

Solana Beach Triathalon

You can participate or simply watch the action at this dynamic coastal event. Billed as a Triathlon, Duathlon & Aquabike, the event starts with a swim in the ocean, then a bike ride along the famed Pacific Coast Highway, and ends with a run along the shore. It’s undoubtedly scenic but don’t be fooled – its also challenging.

Race Day is July 28 this year, but the previous day features a fun Expo event with pep talks for all age ranges. Check the event website for more details.

Cardiff Dog Days of Summer

This event is sure to be a bit hit with kids. Cardiff Dog Days of Summer is a free event held at Encinitas Community Park. Everyone is welcome and dog lovers or owners can peruse the many dog-related vendors, rescue groups, and pet adoption agencies.

Live music, all kinds of dog contests, and a canine obstacle course add to the fun, while food trucks will keep you full and a libation lounge (for a charge) is on hand for the grown ups. The San Diego Fire Department will also be in attendance to feature educational and fun demonstrations throughout the day.

Cardiff Dog Days of Summer is held on Sunday, July 21 and the fun kicks off at 10am.

Things to Do in San Diego in July

July marks the start of my three favorite months in San Diego. Most of the top things to do in San Diego and things to do in San Diego with kids can be done during this month (and really any month) so here are some ideas.

Go to the Beach

I’ll say it again, but one of the most popular things to do in San Diego in July is to go to the beach. The ocean temperatures are trending upward so boogie boarding, swimming, and quintessential Southern California beach days are in full swing.

Go Kayaking in La Jolla

July is a fantastic month for kayaking around the La Jolla Underwater Park to see this marine life rich area, our sea caves, and enjoy the sunshine. You can do it on your own or take a tour.

Enroll in Surf Camp

One of my favorite San Diego activities for kids during any season is learning how to surf. Arrange a private or group lesson with one of our highly-regarded San Diego surf schools. Many of them offer half-day or full-day summer camps for kids.

Try Bay Water Sports

You can rent everything from stand-up paddleboards to ski boats at various centers like Action Sports Rentals along Mission Bay or in Carlsbad at Agua Hedionda Lagoon.

Check What’s Happening at Theme Parks and Museums

Usually, July means really cool programming at Balboa Park museums and our theme parks. Pick your favorite and go according to what’s on. We’re talking science labs for kids, nature walks, and much more.

LEGOLAND California usually offers its own fireworks display on July 4th in addition to other patriotic, LEGO-themed festivities. (Learn how to buy discount LEGOLAND California tickets.)

What to Pack for San Diego in July

As during any season, what to pack for San Diego in July includes layers. The days are long with the sun setting at 7:30 p.m. or later. Tank tops and shorts during the day are normal thanks to sunny San Diego July weather, but you’ll want a sweater or light jacket in the evening.

If you’re planning to enjoy a beach bonfire, a pair of sweats, sweatshirt, and a blanket are good to have on hand. Be sure to also pack:

• Bathing suit
• Rashguard or UV shirt for sun protection
• Sunglasses
• Sunscreen
• Hat
• Flip flops
• Bathing suit cover-up
• Shorts
• T-Shirts
• Tank tops
• Sweatshirt, jacket or wrap for evenings
• Casual dress or collared shirt and nice jeans

If you’re going clubbing downtown, check the dress code requirements as they can be strict in some places.

Saving Money Around San Diego in July

People tend to be out and about in July so it helps to know the ways to save in San Diego. Tourists who are trying to fit in all of the theme parks and museums should take a look at the All-Inclusive Go City San Diego Card that lets you save up to 50% on admission to over 55 attractions.

And, for individual tickets keep in mind that I have a San Diego Zoo tickets promo code and a San Diego Zoo Safari Park ticket promo code.

Lifestyle: What Residents Are up To

When we’re not shuttling the kids back and forth to summer camp and sports, we’re also out and about enjoying San Diego July weather. We tend to avoid the crowds in downtown San Diego surrounding Comic-Con and driving anywhere near the racetrack where people are coming and going from the fair and horseraces (unless we’re attending).

If there’s one thing to put on your summer bucket list, it’s find a great San Diego restaurant with patio dining. Whether at home or out, we’re eating outside, because we can.

We’re also exercising outside. You can find everything from beachside yoga to outdoor boot camp. And, of course, we’re enjoying beaches and swimming pools.
