The Lowdown
G'day, I'm Rusty. Let's have a look at what's on offer at Zepotonengo.
We've got a solid run of Southern Ocean groundswell lining up over the next couple of weeks. The water temperature is sitting at 88°, which is a touch warmer than normal for this time of year. The first surf worth paddling out for kicks off on Wednesday the 9th of September.
Wednesday morning is a beauty to start. Clean, glassy conditions on offer with a 3ft swell out of the SW, with a very long period of 16 seconds. The whole ocean's got moderate energy pushing in (577). It's a great beginner-friendly size, and with that offshore wind from the W and calm water, the waves will be peeling nicely. Thursday the 10th morning is the standout. The swell jumps up to 5ft from the SW (1063 combined energy – strong), and it's glassy calm. The period’s still a long 16 seconds. This puts it in the sweet spot: plenty of push but not too big for most. The afternoon gets a bit lumpy with a cross-onshore breeze, so hit the dawn session.
Friday the 11th morning keeps the clean theme with 4ft SW swell (761 combined energy) and glassy conditions. It's a seriously fun run of mornings. Saturday the 12th morning is smaller at 3ft (458) but still clean and glassy. Sunday the 13th morning has dropped to 2ft (251) – still glassy, but lower energy for a lazy session.
There's a brief slump Monday the 14th and Tuesday the 15th with onshore winds chopping things up Tuesday afternoon, but the early sessions still have some clean windows. Wednesday the 16th morning is another glassy gem with 4ft SSW swell (967 combined energy). Thursday the 17th morning has 4ft SSW swell, glassy and clean (843). Friday the 18th morning keeps the good form going with 3ft SW swell and very long period of 20 seconds (788). That long period will see longer waits between sets, but the wave shape will be proper at a point or reef.
The following week stays active. Saturday the 19th and Sunday the 20th both have clean, glassy mornings with SW swell around 3–3ft. The energy is moderate but surfable. Then Monday the 21st morning brings a bigger pulse: 4ft SW swell (1149 combined energy – strong) with glassy conditions and clear skies. This one's for the experienced crew as that size with a 17-second period will have some grunt. The rest of the week settles into a pattern of glassy mornings and scrappy afternoons. Overall, the first week's mornings are the real standouts, especially Thursday the 10th morning. There's no shortage of clean options. Conditions look a bit more variable further out, and the afternoons consistently get chopped by a cross-onshore breeze. If you can, paddle out early and enjoy the glass.
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.

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.
