The Lowdown
Record: 16 September – 01 October
Alright, listen up. We’ve got a solid run of surf to work with here, but it’s all about timing. The first few days are your best bet, and the pick of the whole lot is the 20th and 21st. The windows are clean, the swell is on, and it’s proper fun.
Wednesday, 16 September morning: 1.3m of SSW groundswell, 16-second period, glassy winds. The energy is moderate at 969. It’s clean, it’s pushy, and it’s perfect for a beginner spot like this. Afternoon goes cross-on, but the morning is gold.
Thursday, 17 September morning: similar story—1.2m, 14 seconds, zero wind. Glassy as. The energy’s a touch lower (832), but it’s still fun. Morning only, though; afternoon gets ripply.
Friday, 18 September morning: smaller at 0.8m, but that 20-second SW groundswell has some serious push for the size. Clean, calm, and super glassy. It’s a smaller wave, but the quality is high.
Saturday, 19 September morning: 0.8m, clean, but the afternoon turns to chop. Not your window.
Sunday, 20 September morning: here it is. The swell bumps back up to 1.1m, SW, 19 seconds, and it’s glass. The energy jumps to 1144—that’s proper, solid, and consistent. This is the best day of the whole run. The water temp is about normal for this time of year, so no surprises there.
Monday, 21 September morning: nearly as good—1.3m SW at 17 seconds, light offshore, energy over 1000. Another cracker. The consistency is there, and it’s clean.
From the 22nd onwards, it fades. The mornings are still glassy, but the swell drops to 1.1m, then 1.0m, then 0.7m by the end of the month. The afternoons turn onshore or cross, so it’s a morning-only spot for the rest of the run.
Sunday, 27 September morning: the biggest of the whole period at 1.6m, but it’s a short-period 13-second SW, so it’s messier and less powerful. Still clean, but it’s for the better surfers. Not a standout.
Monday, 28 and Tuesday, 29 September are average. Small, weak, and the wind is onshore. Not worth the effort.
Tuesday, 29 and Wednesday, 30 September are pretty poor—small and weak. The 1 October morning finally gives a decent, clean, small wave—0.7m at 18 seconds, glassy, and super fun for the size.
So, the standout is the 20th and 21st. If you only get one session, make it the morning of the 20th. Clean, solid energy, and the optimum direction is right. The long period means it might straighten out a bit at this beach, but it’s still super fun.
After that, it just runs out of gas. No big epic swells in the second week, so don’t hold out for something huge. Get on it early.
Rusty out.

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.
