The Lowdown
Alright folks, Rusty here. Let's have a look at what's cooking for the San Juan zone. I'm not gonna lie to ya, this is a tough stretch of forecasts. We're looking at a solid 16-day window, but the ocean just isn't playing ball for most of it. There's a good 12 days of straight-up no-go conditions on the cards, with constant onshore winds making a mess of things.
The only real glimmer comes right at the tail end. But first, you gotta earn it. The first week is pretty much all crossed off. 25 mph winds on the 1st, 22 mph on the 7th and 8th... The water's sitting at 74.7°F, which is a touch warmer than normal for this time of year, but you won't want to be out there to feel it. The combined swell energy is moderate, peaking at the start around 662, and then again around the 7th at 562, but with the wind state being "on" or "cross-on" from the North, the quality is completely shot. This is a reef break, but with those conditions, it's not even worth paddling out.
The real standout, the only one that gets even a whisper of excitement, is Sunday the 13th. The morning of the 13th the wind drops off to a glassy 3 mph. That's a major positive – we're talking clean, open faces. The swell is small, just over 4ft from the NNE with a period of 7 seconds, and the combined energy is a moderate 276, so it's weak. But for a few hours there, it's the only time you'll find a smooth surface. It's an expert-level reef, and it's consistent, so on that Sunday morning, the lineup should be clean. It's a consolation prize, but it's the only prize on offer. The period is short, so the waves will be a bit fat and sectiony, but at least they'll be clean.
After that, the 14th through the 16th slides back into messy onshore slop. The 16th morning does see a long period 14-second swell from the NNW with energy in the moderate range at 464, but the onshore wind from the NNE ruins the party. For this zone, that's another blank day.
So, be patient. That Sunday the 13th, early morning, is your one short window for a paddle. Go get it while it's glassy.

Information about the San Juan Surf forecast
The above surf forecast table for San Juan provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at San Juan can be found by selecting the local surf guide option on the grey menu. Our San Juan surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (San Juan) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for San Juan may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
San Juan is 8 km (5 miles) from Teguise. If you plan a holiday in Lanzarote, look for hotels and other accommodation in Teguise. Teguise has rooms for a wide range of budgets as well as car hire and transport links.
