The Lowdown
Alright folks, Rusty here. Let’s break down what’s coming for the local zone.
Honestly, I’ve gotta lay it out plain – this 16-day window is a real bummer. The only break we’re looking at is Los Tubos, a reef setup that’s fairly consistent, but the wind is just a problem. We’ve got a steady cross-onshore breeze from the ENE, gusting up to 22–25 mph at times, and it’s wrecking the surface. The swell is coming from the wrong direction, too – straight out of the ENE – when this spot really wants it from the NNE. It’s a mismatch from the start.
The whole early period, from Tuesday the 4th through the first week, is flat and choppy. Swell heights are mostly 3 ft to 4 ft, with short periods of 5–8 seconds, and combined wave energy is weak – mostly under 100. The water temp is about average for the time of year, nothing special.
Things do build a bit in the second week. Around Thursday the 13th, the swell starts to push up, and by Friday the 14th we’re looking at 6 ft to 6 ft of ENE swell with 7–8 second periods. The energy jumps into the 300s, so there’s some real power behind it. But that ENE wind is still blowing 22 mph cross-onshore, making it a messy, lumpy mess. This is looking more like a kite-surfing day than a clean paddling session.
If I had to pick one window, it’d be the morning of Saturday the 15th of August. Swell is still solid at 6 ft with 8-second period and energy at 391 – the highest of the whole run. The wind is still cross-onshore but a little lighter at 16 mph. It’s gonna be rough, but for experts who don’t mind the chop, there might be a few workable walls. Beginners, stay away – 6 ft is too big for you, and the conditions are ugly.
No standout session here. The whole 16 days is a stretch of poor quality. The wind just won’t swing, and the swell direction is wrong. It’s a long gap of nothing good. But hang in there – it usually doesn’t stay this poor for long, and forecasts can shift.
Rusty.

Information about the Los Tubos Surf forecast
The above surf forecast table for Los Tubos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Los Tubos can be found by selecting the local surf guide option on the grey menu. Our Los Tubos 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 (Los Tubos) 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 Los Tubos 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.
