The Lowdown
Alright, let's talk conditions in the water at Zepotonengo in the units you might be more used to. The water is sitting at a warm 88°, feeling a touch warmer than normal for this time of year. We've got a long run of waves coming, with just a few afternoons that'll get chopped up.
Wednesday morning (August 12th) is a great starter. Glassy conditions, clean lines, and a 3ft SW groundswell running at a long 16 seconds. The combined energy is moderate at 555, and with the wind dead calm, it's a perfect session for the beginners. The afternoon turns onshore, so get in early.
Thursday morning (13th) is much the same – 3ft from the SW, glassy wind, and a clean surface. The swell period is still a solid 15 seconds, keeping the waves tidy.
The real standout is Friday morning (August 14th). The swell bumps up to 4ft, but the period goes to a very long 18 seconds, giving it a lot of power. The combined energy is strong at 1123, and with the wind calm and glassy... this is top-tier for the experienced crew. That long period means the sets will be spaced out, making the paddle out easier, and the shape at this exposed spot should be smooth. Saturday morning (15th) is a close second, with 5ft of SW swell and glassy conditions, also an excellent choice for experts.
From Sunday morning (16th) through Wednesday morning (19th), you got a consistent run of waist to chest-high swell around 4ft, with clean, glassy conditions each morning. The energy stays moderate, and the crowds are *sometimes* a factor, so you might see a few others, but it's a solid stretch.
The second week gets a bit more mixed. Thursday morning (20th) brings a shift to a shorter period SSE windswell, but it's still 4ft and glassy. Then we hit a few days of smaller, wind-affected surf. The next glimpse of something good is Monday morning (August 24th) – a small 2ft swell, but coming from a very long 18 seconds again, and it's glassy. Perfect for a longboard if you've got the patience. It's a long way out, so less certain, but the potential is there.
So, the cream of the crop is Friday morning (14th August) for the powerful, clean groundswell, with Saturday morning (15th August) as a fantastic backup. Get out there and get some.

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.

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.
