The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Zepotonengo over the next couple of weeks.
We’ve got a solid run of surf on the cards, but it’s a bit of a mixed bag with the wind. The standout morning is definitely Saturday, August 15th. The swell is pushing 5ft from the SW with a long 16-second period, and with glassy conditions, it’s going to be firing. The energy is strong at 1200, so there’s plenty of grunt in the water. It’s a good one for experienced surfers, as 5ft can be a bit much for beginners. The water temp is about average for this time of year, so no wetsuit worries there.
The morning of Sunday, August 16th is also a real treat. The swell drops to 4ft from the SW, but it’s still got a long 15-second period and the wind is dead calm. The energy is moderate at 728, but the glassy conditions will make for some clean, peeling lines. This is a great option for intermediate surfers, too.
The first few days are a bit of a slow burn. Thursday morning, August 13th, has a small 3ft SW swell with a 15-second period, and it’s glassy, but the wave energy is weak at 392. It’s a gentle start. Friday morning, August 14th, is a little bigger at 4ft, but the cross-onshore wind will mess up the surface a bit. The energy is moderate at 1203, but the wind is the issue.
The afternoons are generally a write-off due to the persistent cross-onshore wind, so don’t bother with those. The mornings are where it’s at.
The second week sees the swell start to fade. The morning of Sunday, August 23rd is worth a mention: glassy conditions with a 2ft SW swell, but the period is a very long 18 seconds. The energy is moderate at 648, and that long period means the waves will have some shape, but it’s small. The morning of Monday, August 25th is also glassy with a 2ft SW swell, but it’s a weak 414 energy. The very end of the window, on Friday, August 28th, looks promising with a glassy morning, a 3ft SW swell, and a 16-second period, with energy at 686. It’s a long way off, but it has potential.
Overall, the best bet is the Saturday morning, August 15th. It’s a proper session with size, power, and clean conditions. The Sunday morning, August 16th, is a close second for cleaner, more manageable waves.
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.
