Frequently Asked Questions

What kind of wave is San Juan?

San Juan is a reef break in Lanzarote, Spain, that mostly breaks left.

What swell works best at San Juan?

San Juan picks up swell from the WNW round to the NNW, and it's best when it's coming straight out of the NW. It starts working at around 1m and handles up to about 2.5m, with the sweet spot around 1.7 to 2.1m. Period matters too: aim for 14s or longer, as anything under 11s 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 San Juan?

A SE wind is dead offshore at San Juan, and anything from the E round to the S 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 San Juan?

San Juan is at its best around the low to mid tide, roughly 0.3m to 1.5m on the local chart.

When is the best time of year to surf San Juan?

The most reliable run of swell at San Juan comes Oct to Mar. Consistent hollow left near La Santa.

How cold is the water at San Juan?

The water at San Juan averages around 20°C, so you'll want a 3/2mm fullsuit. It shifts a few degrees through the year, so check the season before you pack.

Is San Juan good for beginners?

Not really. It's rated 7/10 for difficulty and suits experienced surfers. Expect a moderate crowd (5/10) when it's on. Shallow reef sections.
