The Lowdown
G’day, Rusty here.
The outlook for Zepotonengo is starting a bit quiet, but we’ve got a really solid run of surf on the way. The water’s sitting at 87°, a touch warmer than normal for this time of year, so you won’t be needing the thick rubber just yet.
The first real action kicks off Friday afternoon (August 28), but it’s marginal – 5 ft of SW swell at 18 seconds with a cross-on breeze. That’s a groundswell with some serious legs, but the wind’s messing it up. Saturday morning (August 29) is where it gets interesting: glassy conditions, 6 ft SW swell at 16 seconds, and combined energy at 1656 – that’s strong, meaty surf. It’s big enough to be too much for beginners (over 5 ft), but experienced surfers will be loving that clean, lined-up groundswell. That 16-second period means longer waits between sets, but the shape will be excellent on the reef or points. Sunday morning (August 30) keeps it clean and glassy again with 5 ft of SW swell.
The standout session is hands-down Saturday morning (August 29). Glassy winds, 6 ft SW swell, and that high combined energy (1656) – it’s a ripper. The swell is a bit big for learners, but for anyone who’s comfortable in that size, it’s going to be firing with clean, groomed faces.
Monday morning (August 31) stays glassy with a lighter 4 ft SW swell, and then we hit a bit of a lull through Tuesday and Wednesday afternoons, with smaller surf and onshore winds. But it picks back up: Wednesday morning (September 2) is glassy with 3 ft SW swell and good shape, and Thursday morning (September 3) has 3 ft of that long-period SW groundswell (18 seconds) and glass – it looks super clean but a bit small.
The real second standout is Friday morning (September 4): glassy again, 5 ft SW swell, 17-second period, and combined energy of 1803 – that’s strong. Another one for experienced surfers, with long, powerful lines. Saturday morning (September 5) is also solid: clean cross-off wind, 6 ft SSW swell, and energy of 1586.
After that, the following week (September 6 onward) keeps pumping but with a mix of smaller days and morning glass. Sunday morning (September 6) is worth a paddle with 5 ft SSW swell and glass, and then we see a couple more clean mornings around September 10 and 11, though the swell drops to around 4-5 ft. Crowds are possible here, so Sunday morning might be the time to get a few peaceful ones.
No real blank runs here – even the smaller days offer clean morning windows. The long-period groundswells are best at the point or reef, not the beach break.
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.
