You might expect uniformly hot weather in Tijuana, but this Mexican border city actually enjoys a mild, Mediterranean climate. Much like just north of the border, in southern California, summers are warm and dry, whereas winters are cool and occasionally rainy. You’ll find the warmest weather in August and September, and the coolest in January, which is also the month with the most rain. The temperature in Tijuana rarely dips below 45 degrees F, and most days are sunny, even in winter. Some years the dry Santa Ana winds sweep down from California bringing hot weather in the autumn. In general, the best time to visit is in the spring, though if you’ll be including a visit to the beach, you may prefer to visit in the summertime. If you do, you'll be in good company: summer is the busiest tourist season.

Spring in Tijuana

The weather in Tijuana is agreeable in the springtime, with highs ranging from the high 60s to mid 70s F, with warmer temperatures toward the end of the season as summer approaches. Spring is the second busiest time of year for tourism, and there are several interesting things to do, such as visiting the Tijuana estuary, which is a beautiful nature preserve (located on the U.S. side of the border) that's filled with wildflowers this time of year.

What to pack: Comfortable street clothes such as jeans and a T-shirt are fine for shopping and day-tripping. You’ll likely do a lot of walking, so closed-toe shoes are your best bet. Don’t wear jewelry, and do carry your essentials in a day pack or cross-body bag. Don’t forget your sunglasses and some sunscreen.

Summer in Tijuana

From June to August, the weather in Tijuana is pleasantly warm and dry. The highest temperatures come in late August and early September, though it's not uncomfortably warm, with highs regularly reaching around 84.5 degrees F (29 C) and rarely dropping below 66 degrees F (19 C) at night. It virtually never rains in Tijuana in these months, so you can expect dry weather. Summertime is the busiest season for tourism in Tijuana, so lodging and other tourist services may be a bit more costly than other times of the year, and line-ups at the border tend to be longer. This is also grape harvesting time in nearby Valle de Guadalupe, and there are many special events held to celebrate.

What to pack: Warm weather clothing like shorts and T-shirts are perfect for this weather. You may want to carry a sweater or sweatshirt for air-conditioned indoor spaces. If you’ll be going out in the evening, pack something a little spiffier, though Tijuana is a laid-back destination, and casual clothes are acceptable in most establishments.

Fall in Tijuana

Warm weather continues into the fall, with September seeing high temperatures very similar to August. The Santa Ana winds may bring in hot, dry breezes, and sometimes usher in a heat wave; these winds generally peak in October. Daily highs in the fall months range from the high 60s to low 80s F. Temperatures begin to cool down, and rains start to become more frequent toward the end of the season. This is generally the low season for tourism, so you may find some good deals on hotels and tourist services.

What to pack: It’s a good idea to dress in layers so it'll be easy to adjust to any changes in temperature. Jeans, sweaters, and a light jacket are your best bet, and pack a travel umbrella, just in case you get caught in a drizzle.

Winter in Tijuana

Although far from harsh, the weather in Tijuana is cooler during the winter months, generally too chilly for swimming or water sports, and those hoping for heat are likely to be disappointed. The average highs during this season are between 64 and 71 degrees F. January is the coldest month, and also the month with the most rainfall: there are about six rainy days in the month, with an accumulation of just under two inches of rain. This is low season for tourism, however, it is the time of the gray whale migration, so if you’d like to go on a whale-watching trip, the time to do it is between December and April. 

What to pack: You’ll be most comfortable wearing long sleeves and slacks or jeans, and be sure to pack a fleece or light jacket for when the thermometer dips. Also make sure there's an umbrella or rain jacket in your suitcase for those winter showers.
