Sargassum Seaweed In Cabo San Lucas in September

Sargassum seaweed is a concern for beachgoers, even in some of Mexico’s most popular beach towns. Large quantities of this seaweed show up on many Caribbean coast beaches in the country, especially in the summer.

Luckily, it’s not a problem on the Pacific Ocean side and the Sea of Cortez side of Mexico, so the beaches in Cabo San Lucas are completely free of seaweed.

Mexican Independence Day is a big national holiday, so it’s no surprise that the celebration is huge in Cabo San Lucas as well.

You will find lots of crowds gathering in the streets on the 15th day of the month, who continue the celebration with live mariachi music, dancing, fireworks, and beers until the cry for independence (grito) near 11.

Cons of Visiting Cabo San Lucas in September

👎 September is still a couple of months too early if you want to encounter some whale sharks and humpback whales, as these majestic creatures only start showing up at the Los Cabos shores when winter is around the corner.

On the other hand, instead of whale watching, you can still go snorkeling with the sea turtles, blue marlins, yellowfish tunas, and other marine creatures that are here all around the year.

👎 The weather during September is characterized by higher temperatures and humidity, so you will find the outdoors uncomfortable some hours of the day.
