The Lowdown
Alright, Rusty here. Let’s talk about what’s happening at San Juan.
Look, I gotta be straight with you. The next 16 days are pretty grim. It’s a long stretch of poor surf, with only a whisper of a chance right at the tail end, and even that is a tough sell. For the most part, the wind is howling onshore from the north-northeast, blowing out what little swell there is. The energy is weak, mostly in the range of 120 to 575 (moderate at best), and the swell is short-period wind chop—nothing with any real grunt.
For the first week, from Wednesday the 2nd right through to about Sunday the 13th, it’s a write-off. Onshore winds, 9 to 22 mph, and messy, short-period swell. The water temp is a touch warmer than normal at 75°, but you won’t be in the water long enough to enjoy it. There’s a small window around Monday the 14th morning where the period jumps to 14 seconds and the energy hits 262, but the swell is tiny, only 2 ft from the northwest, and the wind is still cross-onshore. It’s a marginal call at best.
Then, into the second week, things get interesting but not for paddle surfing. On Tuesday the 15th, we see a big spike in energy from a long-period groundswell—772 in the morning, 846 in the afternoon, with a period of 15 seconds from the NNW. The swell is 4 ft to 5 ft, which is solid. But, the wind is still cross-onshore or onshore, and up to 16 mph. This is a beach setup, and with that much wind and a long-period swell breaking straight, it’s going to be a mess for a surfboard. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
The best you can say is that on Saturday the 12th morning, the wind drops to a light breeze from the north-northeast (6 mph) and the swell is 4 ft from the north with 8 seconds. Still, the wave comment says "poor surf conditions" and the energy is low at 202. It’s flat, but clean. Not worth paddling out for.
So, there’s nothing here worth highlighting. A long, blank run like this is normal for the area when the trade winds lock in. Forecasts can change, but right now, I’d leave the boards at home.

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.
