Crowds & Costs

It can get a little busier when the school holidays take place in some schools and families visit the coast. Popular beaches and attractions draw more travelers, but it doesn't get nearly as busy as in the winter months. 

Where to Go

A great place to visit in August is the uninhabited Guadalupe Island, which attracts a lot of Great White Sharks, following the colder waters. August to October is Guadalupe liveaboard season. It is about 70 °F in the sea, making it one of the coldest temperatures in Guadalupe. However, you will enjoy visiting the island in August because of the ideal diving opportunities and shark encounters.

The ocean is also at its calmest, which is another reason diving is so good here this time of year. If you want to dive here, you can take a boat tour and have it arranged for you. Since you can only access the island by liveaboard, it is wise to book this in advance if you want to dive. You usually go on a several-day tour, so there is enough time for a lot of fun and many, many shark encounters. 

This is also the month to enjoy liveaboard diving in the Sea of Cortez. The waters here are much warmer than Guadalupe with approximately 80 °F. In August-November, you have the best chance to encounter hammerheads in this region. In the city of La Paz, there are a lot of lovely beaches to choose from.

Surrounded by mountains, there are ancient ruins all over the place with some great views of the valleys below.
