The Lowdown
Alright, let’s talk surf. It’s been a bit up and down, but there are some good windows if you play it smart.
Water’s sitting about 87°F, which is a touch warmer than normal for this time of year, so it’s boardies weather.
The first real standout is Tuesday morning, September 15 at Zepotonengo. Clean 4ft of SW swell, glassy conditions with a light offshore breeze. The energy’s building, sitting around 940 – solid moderate. It’s not huge, but it’s clean and fun. That’s your best bet early on.
Wednesday 16 and Thursday 17 mornings are similar – clean 4ft SW swells, glassy with light offshore winds. Consistent and clean, perfect for this break. Get out early; the afternoons get chopped up with cross-onshore breezes.
Then Friday 18 and Saturday 19 drop off – under 3ft and weaker. Still surfable, but you’ll be scratching for waves.
Now, the standout of the first week is Sunday morning, September 20. We’ve got 4ft of SW groundswell with a 19-second period – that’s serious juice. Clean conditions with a light cross-offshore breeze. The energy is 1166, which is strong. This is the pick of the bunch. The long period will give it real shape and push.
The second week starts to see more size, but the conditions get messy. Saturday 26 morning is glassy with 4ft of WSW swell, energy at 968. That’s a good one.
Then Sunday 27 things pick up. Swell jumps to 5-6ft with a 12-second period, and the energy is pumping – 1475 to 1671. That’s strong, but the wind is onshore and there’s a thunderstorm risk. This is getting into expert territory, and with the chop, it’s not going to be clean. Probably too much for this break, and it’s going to be lumpy.
Monday 28 gets blown out. Strong onshore winds at 35 km/h plus thunderstorms equals poor conditions. That’s a kite-surfing day for sure, not a paddle day. The swell is there, but the surface is going to be rough.
So, overall: the first week has the cleaner, more fun waves, especially the mornings from the 15th through the 17th, and that standout Sunday on the 20th. The second week gets bigger, but it’s messy and less certain. For clean conditions, stick to the early sessions.
Keep your eye on the forecast, and get out there when it’s glassy.

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.
