The Lowdown
Alright, Rusty here. Let’s take a look at what’s coming up.
The main spot is Zepotonengo. It’s a beginner-friendly, fairly consistent break that’s exposed to the swell, with the best direction coming from the SSW. Water temp is about average for this time of year.
Wednesday morning the 19th kicks it off with a glassy, clean 4ft SW swell, a long period of 15 seconds, and combined energy of 599 (moderate). That’s a solid start – light offshore wind from the ESE at 3 mph, glassy conditions, very good surf. The afternoon goes onshore, so get out early.
Thursday the 20th is a bit of a dud with cross and cross-on winds and small surf around 3ft. Friday morning the 21st is fun again – glassy, calm, with a 3ft S swell, short period of 10 seconds, and combined energy of 273 (weak). Small but clean. Saturday morning the 22nd is similar: glassy, 4ft S swell, 10-second period, 396 (weak) energy. Good for a longboard.
Sunday morning the 23rd is a standout. The swell is only 2ft but it’s a long-period SW groundswell at 18 seconds, with combined energy of 781 (moderate). The wind is light WNW at 3 mph, cross-off, and the conditions are clean. That’s a beautiful lined-up wave for a point or reef – the long period might make the beach breaks a bit fat, but it’s a gem. Monday morning the 24th is similar, with 2ft at 18 seconds and 548 (moderate) energy, clean and cross-off. Tuesday, Wednesday, and Thursday mornings all offer clean, glassy or cross-off conditions with small SW swell, solid period around 16-18 seconds, and moderate energy.
The big highlight is Friday morning the 28th of August. We’ve got a 4ft SW swell with a 16-second period, combined energy of 805 (moderate), and glassy conditions with a light WNW wind. That’s very good surf. The afternoon gets messy with a risk of thunderstorms and onshore wind, and the swell bumps to 5ft, but the morning is the one.
Saturday the 29th sees the swell build to 5ft, with a 16-second period and combined energy of 1430 (strong to very strong). The wind is cross-shore from the east at 12-18 mph, so it’s going to be lumpy and choppy. That’s a big, powerful swell – better for experienced surfers or maybe kite surfers, given the wind and the beach/reef setup. Sunday the 30th is similar, with 5ft SW swell and cross-onshore winds, so not great.
Monday morning the 31st of August is another clean, cross-off morning with 4ft SSW swell, 14-second period, and combined energy of 746 (moderate). That’s very good. Tuesday morning the 1st of September is glassy with 4ft SSW swell, 13-second period, and 842 (moderate) energy – another winner. Wednesday the 2nd of September offers clean conditions both morning and afternoon, with 3ft SW swell, long period of 16-17 seconds, and combined energy in the 736-934 range. The morning is particularly good.
Thursday the 3rd of September morning has a bigger 5ft SW swell, 16-second period, and combined energy of 1214 (strong), but the wind is cross-on from the ESE, so the surf will be a little lumpy. Still, there’s a lot of energy in the water.
The best standouts are Wednesday morning the 19th, Sunday morning the 23rd, Friday morning the 28th, and Tuesday morning the 1st of September. Get on those windows.

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.
