The Best Time to Visit San Diego

Is October a good time to visit San Diego

The best times to visit San Diego in California are between March and May and then September and October. During these months, crowds are lower, the weather is pleasant, and hotel prices are reasonable.

However, there’s certainly no wrong time of year to visit San Diego. It’s all about what type of vacation you are interested in and what attractions in San Diego are interesting for you or your family.

While the crowds may increase in the summer months, if the beach is your number one concern, you may still want to visit during this time. As with planning any trip, it’s all about balancing the pros and cons of visiting at certain times to choose what is best for you.

Best Time to Avoid the Crowds

The least crowded time in San Diego month is from December to January (except Christmas until New Year’s Eve). September and October are great shoulder months without the heavy summer crowds and a great time to experience pleasant weather.

Best Time for Hotel Reservations

June, July, and August demand the highest hotel prices in San Diego, so book a summer visit 6 to 12 months in advance. For the quieter months, you can afford to book a hotel three months in advance.

Keep in mind that San Diego is a popular convention and conference city. Each July, it hosts the Comic-Con, which is the biggest pop culture by far even in the United States. Best availability for accommodations will be found in the winter months, with the exception of Thanksgiving, Christmas, and New Year.

A truly unique hotel is the Cosmopolitan Hotel – low price via booking.com – in Old Town. This is by far the best choice for accommodation in San Diego overall. The staff is beyond amazing, you experience and if you want to know what it was like in the late 1800, there is no better place. Not convinced? Always check the deals and reviews for other San Diego Hotels with a low-price guarantee.

Best Time to See Seals and Sea Lions at La Jolla

Is October a good time to visit San Diego

The best time to see seals and sea lions on San Diego’s beach is between late April and early June while they are molting. The number of visible seals increases dramatically during that time.

However, the seals and sea lions are always there, no matter what time of year you visit. The best spots are Children’s Pool and La Jolla Cove.

The best time of day to see the sea lions and seals in San Diego is in the morning and later in the afternoon or early evening. Around noon more of them are swimming and looking for food.

Best Time to Visit San Diego’s Museums

The best time to visit a museum in San Diego is in February. Each year in February is museum month, and most tickets are being offered 50% off. You just need to pick up the 50% pass at any Macy’s department store in San Diego. Most museums participate in that program, including the Balboa Park museums, the maritime museum, or the USS Midway Museum.

Of course, all San Diego Museums are worth visiting year-round. The county has fascinating museums from almost every area with truly unique collections. The best ones are the USS Midway Museum, the San Diego Natural History Museum, the San Diego Museum of Man, the Fleet Science Center, and a few more.

The Best Time for the Unique Activities

Best Time for a Family Vacation

Is October a good time to visit San Diego

The best time of year for a family vacation in San Diego is in September. The summer crowds will have departed, but the warm temperatures remain which is typical for Southern California.

Alternatively, May through August is a popular time for families. While crowds are higher, all the city’s attractions and water parks are open. Expect higher temperatures during these months, making it the best time for a family beach vacation. There are also plenty of great events during this time of year, so there’s always something new to see in the city.

Best Time to See Bioluminescence

Is October a good time to visit San Diego

The best time to see bioluminescence is from July to October. You’ll need to head out at night time once it’s dark to see this blue wave.

When the ocean looks brown or red in the daytime, expect a good chance of observing this phenomenon at night. There is no way to predict how long these tides will last, and they can range from days to weeks to months. Unfortunately, there are currently no tools to predict the next tide. By visiting from July to October, you’ll have the best chance of witnessing this incredible sight.

Best Time to Visit San Diego Zoo Safari Park

Is October a good time to visit San Diego

The best time to visit the San Diego Zoo Safari Park is on a 4:30 pm afternoon tour. During this time, temperatures are comfortable, and animals are most active, as they will be roaming around and responsive.

Avoid visiting in the middle of the day, as many are sleeping during the hottest part of the day. During the summer months, you may find the morning tour a good option, where you can avoid crowds, and the animals will be pretty active.

Best Time to Visit SeaWorld San Diego

Is October a good time to visit San Diego

The best time to visit SeaWorld San Diego is in the spring, with May being the top month to visit. The weather is pleasant, the crowds are light, and baby animals are born during this time.

In the spring, the flowers around the park are also in full bloom. The rule of thumb with this attraction is to avoid major holidays and school breaks.

Since SeaWorld is a major attraction in Southern California, try to avoid visiting throughout the summer when kids are out of school. The park is extremely crowded, and the weather is often overcast in June.

Weekdays are quieter at SeaWorld San Diego, but more special events occur during the weekend. These can often be worth braving the crowds for and will add more fun and excitement to your visit. During the peak visitor times, you’ll find more shows are offered each day. It’s up to you to decide whether you would rather enjoy more attractions or a quieter park touring experience.

As with most major attractions and theme parks, you’ll want to arrive at park opening time each day. The first shows of the day attract fewer crowds, making it easier to find a good seat in the stadium. The first hour or two after the park opens is the best time to enjoy the most popular attractions and animal exhibitions without crowds.

Best Time to Surf

Is October a good time to visit San Diego

The best time to surf in San Diego is between August and November. During this time, the swells and winds create fantastic barrels and offshore walls.

Avoid March to May, as the waves are inconsistent during this time. June and July see an improvement in surfing conditions, but August is when the peak surfing season commences. The winter is another good time to surf, although you will experience colder water temperatures.

You’ll enjoy clean water surfaces during the early morning hours each day. If you are looking to enjoy the quietest time in the ocean, visit at around midday on a weekday. Staying near the beach on your trip to San Diego will allow you to enjoy more time in the ocean and catch the waves when they are at their best.

Best Time for Tide Pooling

Is October a good time to visit San Diego

Winter is the best time to enjoy tide pooling in San Diego. The season for tide pooling begins in November and ends in March. The low tides during this time offer the chance to observe more sea life.

Times for the tides change daily, so you’ll want to check the tide table before heading to the beach for this activity. It’s recommended to visit the tide pools around two hours before the low tide recedes until two hours before the water comes back in.

Best Time for Swimming

Is October a good time to visit San Diego

For warm waters, the best time for swimming in San Diego is between July and October. Between November and February, bring a wetsuit if you are planning to swim in the ocean.

Water temperatures are in the low 50s in the winter months and reach the low 70s during the peak of summer. San Diego experiences bigger waves during the fall, so you’ll want to swim with caution during this time.

After a few days of bad rain, you will want to avoid the ocean. The street gutters drain onto the beach, making it very unpleasant to swim. Also, never enter the water when red flags are showing.

For the quietest swimming experience, head to the beach first thing in the morning or around midday on weekdays. Naturally, the weekdays are much quieter throughout the year than weekends for swimming.

Best Time to Visit Balboa Park

Is October a good time to visit San Diego

The best time to visit Balboa Park is during its December Nights. The park is busiest in the summer months, especially during weekends. Visiting on a weekday is your best option to enjoy fewer crowds, and the earlier you visit, the more you can see in the day.

December Nights take place over a few weekends in the month, and you’ll enjoy special events and light displays. While many locals visit during this time, it’s one of the most spectacular times to visit the site. Many visitors spend two to three days enjoying everything the site offers, so arrive early to pack as much into your visit as possible.

Best Time to Watch the Grunion Run

Grunions – San Diego by eric wittman, CC BY

The best time to witness the Grunion Run in San Diego is in spring, between April and June. It can only be witnessed during this season, and fishing is off-limits in April and May.

After high tide and during a full moon, you have the best chance of viewing the fish in large numbers. The largest number of fish usually appears an hour after the Grunion Run commences. Check online for the schedule before heading out, as there is usually a two-hour period each evening where the most activity is expected.

Best Time for a Wedding

Is October a good time to visit San Diego

San Diego experiences minimal rain in the summer, making it the best time for a wedding. Avoid June gloom near the coast by opting for a wedding between July and September.

If budget is a concern, opt for the fall or winter months. In the fall, you’ll escape the heat and find some great deals on venues and hotels. Avoid Thanksgiving and Christmas, as prices increase again during this time.

If you are planning a summer wedding, book at least one year in advance. For quieter months, you’ll find you can book six months or so in advance and still have good options to choose from.

Best Time to Visit Legoland in Carlsbad

Is October a good time to visit San Diego

The best time to visit Legoland in Carlsbad is between August and February, when the kids are back at school. The summer and holiday seasons are the busiest, with high crowd levels and wait times.

An off-peak visit on a weekday will give you the best chance to enjoy all the park’s attractions. Weekends are busy throughout the year but are particularly unpleasant during the summer months.

Arrive at the park thirty minutes before opening, as the turnstiles and a few attractions may open early. This will minimize your time waiting in line for the most popular attractions.

If you are planning to visit the water park, arrive before 11 am or after 3 pm. The water park is best experienced in the summer months and is closed during the week in the winter.
