The Lowdown
Alright, this is Rusty, and I’m looking at Zepotonengo. The water here is a touch warmer than normal for this time of year, sitting at 31°.
We’ve got a long stretch of surf ahead, but it’s not all good. The first few days are small and messy, with a weak 2ft, 15-second period swell on Wednesday afternoon and the combined energy is pretty low (259). That’s not worth paddling out for.
The first real standout comes Thursday morning, the 27th of August. Swell height is still modest at 2ft, but the period jumps to 18 seconds, giving it a long-range groundswell feel. The combined energy climbs to moderate (441). What makes it special is the glassy conditions – dead calm, no wind. That’s a clean, low-key session for the beginner-friendly waves here.
But the real highlight is Saturday morning, the 29th of August. The swell builds to 5ft from the SW, with a 16-second period and strong energy (1544). The wind is glassy, and it’s delivering excellent surf for experienced surfers. That’s your best window.
Friday morning, the 28th, is also a solid option with 3ft, 16-second swell, glassy conditions, and moderate energy (759). It’s a good warm-up for the weekend.
Things get even better on Friday morning, the 4th of September. The swell jumps to 6ft from the SSW – that’s expert territory – with a 17-second period and very strong energy (2075). Glassy conditions again. That’s a strike.
The next morning, Saturday the 5th, is also excellent for experienced surfers, with 6ft, 16-second SSW swell and glassy winds (1474 energy). Two solid days back-to-back.
Wednesday morning, the 9th of September, delivers another excellent session: 5ft, 16-second SW swell, glassy, strong energy (1139). That’s a later standout worth keeping an eye on.
Throughout the run, the mornings are the clear winners – glassy, clean, and the wind is kind. The afternoons mostly get chopped up by a cross-onshore breeze. The break is fairly consistent, so there’s plenty to work with.
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.
