Las Islitas (Matanchen Bay)

San Blas, Mexico
🌀Strong rips🚶Difficult access

Las Islitas in Matanchen Bay holds the Guinness World Record for the world's longest rideable wave at 5,700 feet. When conditions align—typically needing a large, long-period south swell—the wave can connect through multiple points for rides lasting several minutes. While jetty construction has altered the wave somewhat, it still offers the potential for extraordinarily long rides on the right day. The wave is mellow and forgiving, making those marathon rides accessible to surfers of various skill levels.

Frequently Asked Questions

What kind of wave is Las Islitas (Matanchen Bay)?

Las Islitas is a point break in San Blas, Mexico, that mostly breaks right.

What swell works best at Las Islitas (Matanchen Bay)?

Las Islitas picks up swell from the S, and it's best when it's coming straight out of the S. That's a tight window, so it needs the swell direction to line up. It starts working at around 1.2m and handles up to about 2.4m, with the sweet spot around 1.7 to 2.1m. Period matters too: aim for 17s or longer, as anything under 14s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.

What wind is offshore at Las Islitas (Matanchen Bay)?

A NE wind is dead offshore at Las Islitas, and anything from the NNE round to the ENE keeps it clean. The morning is typically the best window, roughly 6am to 11am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.

What tide is best at Las Islitas (Matanchen Bay)?

Las Islitas is at its best around the mid to high tide.

When is the best time of year to surf Las Islitas (Matanchen Bay)?

The most reliable run of swell at Las Islitas comes Jun to Sep. There's a second window in May and Oct too. Needs specific long-period south swell. Rare but epic.

How cold is the water at Las Islitas (Matanchen Bay)?

The water at Las Islitas averages around 28°C, so boardshorts or a rashguard will do. It shifts a few degrees through the year, so check the season before you pack.

Is Las Islitas (Matanchen Bay) good for beginners?
