The Lowdown
Alright folks, Rusty here. Let’s break down what’s cooking for Zepotonengo over the next couple of weeks.
Right off the bat, we’ve got a solid run of clean, rideable waves coming through. The water is sitting at a warm 88°, which is a touch warmer than normal for this time of year, so you’ll be comfortable in boardshorts or a spring suit.
The first real standout kicks off on Sunday, August 23rd in the morning. We’re looking at a clean 2ft south-west groundswell, with a very long 18-second period. The wind is glassy out of the ESE at just 3 mph, making for perfect conditions. The combined wave energy is a solid moderate 757, and this is a beginner-friendly break that’s fairly consistent. Expect some company though, as crowds are sometimes a thing here. This is a top pick for the early part of the window.
The pattern continues nicely through the week. Monday morning the 24th is flat calm with zero wind and the same 2ft SW groundswell, keeping things clean and fun. By Tuesday morning the 25th, the swell drops a touch to 2ft, but it’s still a clean 16-second SW groundswell with a light cross-off breeze, making for good conditions.
Now, the real fire starts to build toward the end of the month. Saturday morning, August 29th is a standout for the more experienced crew. The swell has bumped up to 5ft from the SW, still with a 16-second period. The wind is a clean cross-off out of the WNW at 3 mph, and the combined wave energy jumps to a strong 1803. This is excellent surf for experienced surfers, and the break is consistent. Remember, over 5ft can be a bit much for beginners.
Then, on Sunday morning, August 30th, we’ve got another excellent session for experienced surfers. The swell is a solid 5ft from the SW, with a 14-second period, and a cross-off wind from the NNW at 6 mph. The energy is still strong at 1085. There’s a risk of thunderstorms, but the conditions are clean.
Looking further out, the swell keeps pulsing. Thursday morning, September 3rd, sees a 5ft SW groundswell with a very long 19-second period, and the combined energy is a powerful 1962. The wind is a light cross-shore, which is okay, but this one is more of a promising look for the second week.
The absolute highlight of the entire 16-day window, though, is Friday morning, September 4th. The swell is pumping at 6ft from the SW with a 17-second period, and the wind is glassy out of the ENE at just 3 mph. The wave energy is a massive 2481. This is excellent surf for experienced surfers, and it will be clean and powerful. Keep in mind, at over 8ft it’s expert-only, but at 6ft, it’s a big, clean, groundswell that will be best on a point or reef setup.
There’s a bit of a gap with no standout recommendations after the 7th of September, but the pattern is consistent enough that it tends not to stay flat for long.
The only real caveat on these long-period, 18-second swells is that at beach breaks, they can sometimes break too straight, so keep an eye on the tide and find a bank that works. For now, get ready for a great run of waves.
Rusty.

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.
