The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a fun run of small, clean swell coming up at Zepotonengo, with a real standout peak later in the window that’s got my heart pumping a little faster.
The water is sitting at 88°—a touch warmer than normal for this time of year, so you can leave the thick rubber at home.
The next couple of weeks start off with some real nice, rideable conditions. Monday the 17th has clean 4ft swell from the southwest with a 14-second period, and the wind is glassy in the morning. That’s going to be a joy, with moderate wave energy (603). The afternoon turns cross-on and a bit choppy, so get it early. Tuesday the 18th repeats the pattern: glassy morning, light air, clean 4ft SW swell. Solid for a beginner-friendly wave.
Wednesday the 19th is a standout within the first week. Morning is dead calm, glassy, with 4ft SW groundswell at 15 seconds. The energy is moderate (582) and the conditions are about as clean as it gets. This is a morning to call in sick for. The afternoon drops off.
Thursday the 20th through Saturday the 22nd keep the trend going with smaller pulses around 3ft to 4ft, mostly glassy mornings. Saturday the 22nd morning has a clean 4ft from the south at 10 seconds, energy moderate (528), and dead calm wind. That’s a fun little window.
Now, there’s a solid gap from Sunday the 23rd through Friday the 28th where things get messy. Winds are onshore or cross, and the swell is hanging around 2ft to 3ft. It’s not a write-off entirely—there are a few glassy pockets like Monday the 24th and Thursday the 27th mornings—but the quality is inconsistent. The 23rd has a risk of thunderstorms and a light cross-shore, so it’s a gamble.
Here’s the real standout. Saturday the 29th morning. The swell jumps to 5ft from the SSW with a 16-second period, and the wind is light and cross-offshore. The energy is strong at 1279. This is an excellent swell for experienced surfers—clean, powerful, and long-period groundswell. That size is getting into the “experts only” zone, but if you’ve got the skill, this is the best on offer. Sunday the 30th morning is also solid at 6ft (energy 1680) but with a cross-shore wind, so it’s not as clean.
Monday the 31st morning has another clean, cross-offshore window with 5ft SSW swell, 14-second period, and energy at 1001. That’s another excellent session for experienced surfers. The week then fades into smaller, clean 4ft on Tuesday the 1st of September morning.
So, the best of the best: Saturday the 29th morning for the big, clean groundswell, and Monday the 31st morning for a slightly smaller but still excellent follow-up.
Crowds are possible at Zepotonengo, so get there early for the glassy windows.
Rusty.

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