The Lowdown
Alright folks, Rusty here. Let’s talk about what’s happening in the water.
Right now, it’s dead calm. We’re looking at a long stretch of tiny, weak swell with dodgy winds through the start of the period. Wednesday the 2nd and Thursday the 3rd have barely a ripple – waves under 2 feet, poor conditions, combined energy is weak (91 at best, then dropping to 28). The water temp is about 68°, which is normal for this time of year, so no surprises there.
Friday the 4th afternoon shows a little bump – about 2 feet from the WNW at a short 8 seconds. The wind finally goes light offshore from the NE, making it clean, but it’s still “ordinary.” Not worth getting wet for.
Saturday the 5th is a write-off – onshore wind, risk of storms, only 3 feet of messy stuff. Sunday the 6th is a bit cleaner with NNW cross-off winds and 4 feet of NW swell at 9 seconds. Combined energy climbs to 184, but it’s still just ordinary. You might snag a couple, but don’t expect much.
Now, Monday the 7th morning is the first real standout. Swell hits 5 feet from the NW with a 12-second period – that’s groundswell. Combined energy jumps to 689 (moderate-strong). Wind is cross-off from the north at 18 mph. For Supertubos, this is the call. The crowd can be a problem sometimes, so plan accordingly. Swell direction matches the optimum SW, and the reef should be working. This one is for the advanced crew – 5 feet is getting big for beginners.
After that, it’s a desert. From Tuesday the 8th through Saturday the 12th, we’ve got almost nothing – flat or tiny 0.3-foot leftovers. That’s a 6-day gap. Winds are strong from the north (18–22 mph), so kite surfers might have a blast, but for paddle surfing, it’s a bust.
Sunday the 13th stays small – 2 feet – glassy in the morning, but not enough. The real return is Monday the 14th morning. We get 2 feet of NW swell at a long 13 seconds, combined energy of 277 (moderate), and calm, glassy winds. The comment says “expect good surf conditions” – that’s a solid 2 out of 10 in this drought. This is your second standout. Small, but the long period and glass will make the lines clean. The afternoon gets bigger at 4 feet with a 12-second period but a cross-shore wind, so stick to the morning.
Tuesday the 15th morning keeps it going – 4 feet from the NW at 11 seconds, light offshore from the NNE, clean, with 276 energy. Wednesday the 16th morning is similar – 4 feet, 11 seconds, light offshore, 331 energy, good conditions. That whole stretch from the 14th to the 16th mornings is your best window. By Thursday the 17th, it fades to 3 feet.
For the long-range, the 14th to 16th is promising but not locked in – forecasts can flip. If it holds, it’s worth the trip.
So here’s the bottom line: the standout is Monday the 7th morning (5 feet, NW, 12s, cross-off). The second best is Monday the 14th morning (2 feet, NW, 13s, glassy). Everything else is flat or marginal. Keep an eye on the 14th.
Rusty.

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