The Lowdown
Alright, let’s get into it, surfers. Rusty here.
First up, we’ve got a solid run of clean surf rolling in this week at Zepotonengo. The water is sitting at 88°F, which is a touch warmer than normal for this time of year – nothing crazy, but nice if you’re used to cooler water.
The standout moment is hands down Sunday morning, August 16. We’re looking at a clean 4ft SSW groundswell, pushing in at a long 15 seconds. The energy coming through is moderate at 762, and the wind is absolutely glassy – dead calm. That’s the kind of session you wait for. The break is exposed to the swell, and with the optimum direction matching the swell direction, it’s going to line up beautifully for a beginner-friendly ride. Just be aware that crowds are sometimes an issue here, so get in early for a peak.
Monday morning, August 17, keeps the good times going – 4ft SW swell, glassy again, and very clean conditions. Energy is still moderate at 603. After the mornings, the afternoons turn a bit messy with a cross-on breeze, so you’ll want to be out early.
Tuesday morning, August 18 serves up another glassy 4ft SW swell – same formula, clean lines. Wednesday morning, August 19, the swell drops just a touch to 3ft from the SSW, but it’s clean with a cross-off breeze (577 energy). These mornings are all solid, consistent options.
Thursday morning, August 20, the swell dips to 3ft, but it’s glassy and clean – worth a paddle for the long, gentle rides. Friday morning, August 21 offers a smaller 3ft S swell with a shorter 10-second period, but again glassy conditions. Not the biggest, but still fun.
Now, from Saturday afternoon, August 22, through to the end of the month, the pattern gets inconsistent. The mornings on Sunday, August 23, and Saturday, August 29, still show glassy conditions with a nice 2ft (August 23) and 5ft (August 29) SW swell, the latter having very strong energy at 962. That Saturday morning is another true standout – a bigger, clean, glassy swell at Zepotonengo. It’s an expert-sized wave at 5ft, so if you’ve got the skills, that’s your window. That’s the closest thing to a second best of the forecast, though the end of August also has a glassy Sunday morning on the 30th with 4ft swell.
There’s a gap with no real recommendations midweek around August 25-28, but the mornings on the 25th and 26th offer small, clean waves if you’re desperate for a fix. The risk of thunderstorms shows up on a few afternoons later in the month, so keep an eye on the sky.
Overall, the first week (starting from August 16) has the most reliable, clean, and consistent surf. After that, it’s about picking the glassy mornings, especially the standout Saturday the 29th.
Stay stoked.

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.
