The Lowdown
Alright, Rusty here, lookin’ at the charts for the next couple of weeks. Let’s be straight with you – it’s a slow, frustrating stretch for most of it. We’ve got one real standout, but you’re gonna have to be patient and wait for it.
The first week and a half is a real grind. We’re lookin’ at a lot of choppy, onshore junk. From Saturday the 25th right through the end of July, the wind is mostly on it or cross-onshore, messin’ up any chance of clean waves. There’s a few moments of glass on the 27th and 28th, but the swell is tiny – 3 ft and 1.0 ft – with weak energy. Just not worth paddling out for those scraps.
The real kicker, the one that’s got my heart beatin’ a little faster, is the morning of Saturday, August 1st. That’s the one. Cogumelo is gonna be the spot. The swell’s comin’ from the WNW at 5 ft, with a period of 10 seconds – that’s got some decent shape to it. The combined energy is a solid 411, which is proper, and the wind? Dead glass. Offshore from the WNW at just 3 mph. It’s gonna be a stunning morning. The swell direction is a good match for the spot’s preferred SW window, so it’ll be hitting it nicely. That’s your best window, no question. It’s intermediate-friendly at that size, so just about everyone can get a piece of it. Just be aware that crowds are often here, so get in early.
After that high, it’s back to the struggle. The rest of the first week of August is a mess of cross-onshore winds and choppy conditions. The swell hangs around but the wind just kills it. There’s a bit of a gap with no real recommendation from the 2nd to the 9th. It’s a lot of poor surf with sideways wind. The swell bumps up to 6 ft on the 6th, but with a 6-second period and strong onshore wind, that’s just a washing machine. Probably more fun for a kite than a paddle.
So, keep your eyes on that Saturday morning, August 1st. It’s the only true standout. The rest of the run is a write-off.
Rusty.

A general guide to surfing at Cogumelo can be found by selecting the local surf guide option on the grey menu. Our Cogumelo 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.

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 Cogumelo 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.
