The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Zepotonengo over the next couple of weeks.
We've got a bit of a slow start, but don't write it off. The water is sitting at 87° right now, which is a touch warmer than normal for this time of year, so the boardies are definitely the go.
The first real window of opportunity is Wednesday morning, the 12th of August. It's not huge, with a 3ft swell coming from the SW, but the wind is glassy. Absolutely dead calm. That's a major positive, meaning the surface will be like a mirror. It's a solid option for a beginner-friendly wave, and it's fairly consistent here.
The standout period, though, is the end of the week. Friday morning, the 14th of August, is where it gets interesting. The swell bumps up to 4ft from the SW, but the energy is ramping up significantly (1165). That's a solid kick in the guts of energy. The wind is glassy again, and it's looking excellent for more experienced surfers.
But the real pick of the whole forecast is Saturday morning, the 15th of August. The swell holds at 5ft from the SW, with a combined energy of 1192. The wind is a perfect glassy calm. This is the kind of morning you set your alarm for. It's getting a bit sizey for the beginners, but for anyone with a bit of experience, this is the one to circle. The 16-second period is a proper groundswell, so expect some nice lines.
We get a few more clean mornings after that, like Sunday the 16th and Monday the 17th with glassy conditions and 4ft to 4ft swell, but the energy drops off a bit. The pattern then settles into a mix of clean mornings and choppy afternoons, with the swell hovering around the 3ft to 4ft mark.
Keep an eye on Wednesday the 26th of August. It's a long way out, but the models are hinting at another strong pulse of SW swell (4ft, 1283 energy) with glassy conditions. It's a promising outlook, but we'll have to see how it firms up.
There’s a few afternoons where the cross-onshore wind messes things up, but the mornings are consistently the best bet. For a spot that's fairly consistent, the wait for clean waves isn't too long.
Stay stoked.
Rusty.

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.
