Gas Chambers

Aguadilla, Puerto Rico
🪸Sharp reef⚠️Shallow😮‍💨Hold-downs

Gas Chambers lives up to its name—a heavy, hollow reef break that produces some of the most intense tubes in the Caribbean. Located on Puerto Rico's northwest coast near Aguadilla, the wave jacks up over shallow reef and throws thick, square barrels. Not for the faint of heart, but when it's on, it's one of Caribbean's most intense experiences.

Frequently Asked Questions

What kind of wave is Gas Chambers?

Gas Chambers is a reef break in Aguadilla, Puerto Rico, with peaks that run both left and right.

What swell works best at Gas Chambers?

Gas Chambers picks up swell from the WNW round to the N, and it's best when it's coming straight out of the NNW. It starts working at around 1.2m and handles up to about 3.7m, with the sweet spot around 2.3 to 3.1m. Period matters too: aim for 14s or longer, as anything under 10s 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 Gas Chambers?

A SE wind is dead offshore at Gas Chambers, and anything from the E round to the S keeps it clean. The morning is typically the best window, roughly 6am to 10am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.

What tide is best at Gas Chambers?

Gas Chambers is at its best around the low to mid tide, roughly 0.3m to 1.2m on the local chart.

When is the best time of year to surf Gas Chambers?

The most reliable run of swell at Gas Chambers comes Nov to Mar. There's a second window in Sep to Oct too. Winter NW swells. Hurricane swells possible.

How cold is the water at Gas Chambers?

The water at Gas Chambers averages around 27°C, so boardshorts or a rashguard will do. It shifts a few degrees through the year, so check the season before you pack.

Is Gas Chambers good for beginners?

Not really. It's rated 8/10 for difficulty and suits experienced surfers. Expect a moderate crowd (6/10) when it's on. Heavy, hollow tubes. Name earned from intense barrels.
