The Lowdown
Alright, Rusty here. Let’s talk about what’s happening.
The outlook at Cantinho is a long, quiet slog. For a break that’s normally very consistent, this 16-day window is filled with more poor calls than good ones.
We start on Friday morning, August 28th, with a 7ft swell from the WNW, a 11-second period groundswell, and a lot of power in the water – combined energy of 1121. But the cross-shore wind messes it up. By the afternoon, it’s even worse. From Saturday the 29th all the way through Monday, September 7th, it’s a rough run. Moderate to fresh cross-onshore winds, lumpy, choppy, and just not inviting. The swell hangs between 1ft and 6ft, but the wind is always wrong.
The first tiny break in the clouds comes Thursday morning, September 3rd. We get a light cross-offshore breeze from the ENE and the report says “clean.” The swell is only 4ft from the NNW with a short 7-second period and a weak energy of 185, but it’s ridable. Then Friday morning, September 4th, is glassy – dead calm – but the swell is tiny, just 1ft from the WNW, energy down at 66. You’d need a longboard.
The one session that truly stands out is Thursday morning, September 10th. The swell jumps back up to 8ft from the NNW, still a short 8-second period, and the combined energy is 591. The wind is a light cross-on from the NW, which isn’t perfect, but it’s the biggest swell of the entire run. For a point break, that size might offer a few corners if the tide plays ball. The afternoon goes onshore, so it’s a dawn-patrol-only deal.
Water temp is about 67°, which is normal for the time of year. Overall, there are long stretches of days with nothing worth paddling out for. The cleanest window is the 3rd morning, and the biggest gamble that might pay off is the 10th morning.
Rusty.

Information about the Cantinho Surf forecast
The above surf forecast table for Cantinho provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cantinho can be found by selecting the local surf guide option on the grey menu. Our Cantinho 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 (Cantinho) 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 Cantinho 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.
