The Lowdown
Alright, Rusty here, let's have a good look at what's cookin' down at Cantinho. This is a really consistent point break, and it's good for beginners, but we got a bit of a dry spell to start things off.
So, for the next little while, we got a lot of wind messing things up. That fresh cross-onshore breeze is just gonna make it lumpy and choppy, and we're not seeing much of a window for clean waves despite some decent swell size popping up.
The first real glimmer of hope comes on Thursday morning, August 20th. It's not big, just a tiny 2ft swell out of the WNW, but the key here is it's glassy. That's a rare treat. The combined swell energy is weak (94), but with zero wind and that little groundswell (9-second period), it's going to be super clean and easy paddling. It's surfable, but nothing to get too excited about.
Then we hit a big gap. From Thursday afternoon all the way until the end of the month, it's pretty much all onshore wind and messy conditions. There's some proper size in there – we see a solid 6ft to 8ft swell from the NNW on and off, with combined energy hitting the 800s and even 900s (moderate to very strong), but the wind is just ruining it. An 8ft swell with a 22-mph cross-onshore is just a washing machine for anybody but a kiter, to be honest. That's expert territory with a side of frustration.
Now, if you're patient and you like a bit of a gamble, keep your eye on Saturday morning, August 29th. The swell is a decent 5ft from the NW, and it's got a nice 10-second period on it. The wind is light from the WSW, just a slight air making a light cross-onshore. It's only rated marginal, but it's the best looking setup in the whole outlook. Could be that sweet spot where the point starts to work. A 5ft NW swell with light wind at a point that loves NW swell... that's the one to watch.
After that, there's another spell of lumpy, choppy junk, with the swell getting big again (8ft) but still mostly cross-on wind. The whole second week is just a story of waiting for that one morning.
So, overall, if you're a beginner, the Thursday the 20th glassy session is your safest bet for a paddle. For everyone else, the standout is that Saturday the 29th. It's far out, so don't book the day off, but that's the one with the most potential for a clean shoulder at Cantinho.
Stay salty,
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.
