The Lowdown
Alright, Rusty here. Let’s break down the coming swell.
We’ve got a consistent run of small, clean mornings, with a few that really stand out. Let’s start with Tuesday, 25th August. Morning at Zepotonengo has 2ft SW groundswell, 16-second period, and a cross-offshore breeze at 6 mph. Water temp is 87°. It’s glassy and sweet. Afternoon turns rougher with a cross-onshore.
Wednesday (26th) is dead calm in the a.m. – 2ft SW, 16 seconds, no wind. Clean as a whistle. Thursday (27th) repeats the glassy 2ft SW, but check the period – 18 seconds (440 energy). That’s a long, powerful groundswell even at small size.
Here’s the big one: Friday, 28th August, glass-off morning at 3ft SSW, 16 seconds (784). Then Saturday, 29th August, we hit 5ft SW with 16-second period (1559) and zero wind. That is the pick of the whole forecast. Solid, clean, and powerful enough for experienced surfers. Beginners should stay in.
Sunday, 30th August, still has glassy 5ft SW from 14 seconds (910). Lovely.
Mornings stay good through Wednesday, 2nd September – 3ft SW, 16 seconds (723), glass. Thursday, 3rd September, same size, 18 seconds (843). Still small but beautifully clean.
From Friday, 4th September, we get a bigger bump: 6ft to 6ft SW/SSW, but the wind turns light cross-shore. That’s still surfable but less perfect. The size means it’s expert-only territory.
The best bet is Saturday 29th August morning – 5ft SW, long 16-second groundswell, dead calm. That’s the one to circle on the calendar.

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.
