The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at Zepotonengo.
Right off the bat, this is a solid run. The water is sitting at 87°, which is a touch warmer than normal for this time of year – you won’t need a thick suit, that’s for sure. We’ve got a consistent SSW to SW groundswell lining up perfectly with the exposed setup here, and for a beginner-friendly break that’s fairly consistent, this is a real treat.
The action kicks off Saturday morning, August 8th. The swell is a clean 4ft from the SSW with a long 16-second period, giving it some real punch. What makes it a standout is the absolute glass – zero wind, not a breath. It’s going to be smooth as silk. The combined wave energy is solid at 776, so there’s plenty of push without it being too much for a beginner. You’ll want to get out early though; by Saturday afternoon the wind swings cross-on and it gets messy.
Sunday morning, August 9th, is another beauty. Similar size, 4ft from the SSW, 14-second period, and glassy again. This is a pattern worth setting an alarm for. The mornings are where it’s at. By afternoon, the onshore wind kills it.
Monday morning, August 10th, is more of the same good stuff: 4ft, SSW, glassy, and 13-second period. The energy is even a bit higher at 650. Very clean.
Now, here’s where it gets interesting. Tuesday morning, August 11th, the swell direction ticks a little more SW and the period jumps to 18 seconds – that’s a proper groundswell. It’s only 3ft, but with that long period, the waves will have a lot more shape and power behind them (combined energy 882). At Zepotonengo, being exposed, this long period might make it a bit straight at times, but with glassy conditions, it’ll still be a joy.
The real highlight of the whole 16-day window looks like the mornings of Friday, August 14th and Saturday, August 15th. On Friday morning, we get 4ft of SW swell with an 18-second period and zero wind – glass. The energy jumps way up to 1110, which is a strong pulse. This is excellent for experienced surfers, but if you’re a confident beginner, it’s still manageable. Saturday morning, August 15th, is even bigger at 5ft from the SW, 16-second period, and the combined energy is 1218. Again, glassy conditions. This is the best on offer for the stronger surfer. It’s right at that 5ft mark, so it might be a bit much for absolute beginners, but the quality is undeniable.
After that, the run continues with solid mornings through to the end of the period. Sunday August 16th through Wednesday August 19th all have clean, glassy mornings with 4ft to 4ft of SW swell and periods in the 14-15 second range. It drops off a little after the 19th, with smaller 3ft days, but still clean in the mornings. Even the afternoons around August 22nd and 23rd stay clean with cross-off winds, which is a nice bonus.
The only real gap is that the afternoons are consistently blown out with cross-on wind. Stick to the mornings and you’ll score every time. The crowds are marked as "sometimes" here, so you might see a few others out during these prime sessions, but with this much consistent quality on offer, it’s well worth sharing the water.
Overall, the standout is that Friday, August 14th and Saturday, August 15th mornings. Bigger groundswell, glassy, and plenty of energy. Don’t sleep on the earlier mornings either – they’re all good. The later part of the second week is smaller but still clean, so it stays worth a look.
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.
