The Lowdown
Alright, let's get stuck into it. Rusty here, lookin' at the charts for the next couple of weeks, and I gotta be straight with ya – it's a bit of a slow start for our stretch of coast.
The first week or so is pretty much a write-off for any decent paddle-surfing. We're looking at a bunch of days with small, weak swell and cross to cross-onshore winds that are just gonna chop everything up. The combined wave energy is mostly below 100 (79, 88, 49, 55 etc.), which is weak stuff. The swell is comin' from the NW mostly, around 1ft to 3ft, with short periods of 5 to 8 seconds. Not a whole lot of push or shape. It's the kind of window where you'd be better off with a kite if the wind's consistent enough for you.
We finally get a little pulse of energy rollin' in on the 25th (Saturday) with the swell bumpin' up to 4ft in the morning, and the combined energy hittin' 144 (moderate). But the wind is still a crummy cross-onshore, so it's not going to be clean. By Saturday afternoon, we're seein' 5ft of swell with 276 energy, but the wind picks up to 25 km/h from the NW, so it's gonna be a lumpy, choppy mess.
Sunday the 26th actually shows some promise in the morning with 6ft of NW swell and 378 energy (moderate). The wind is a pure cross-shore from the N at 15 km/h, which is a step in the right direction. The forecast calls it "marginal," but a cross-shore with that much energy could be okay for a few corners if you're not picky. The afternoon gets ruined again by a 30 km/h cross-onshore, so the morning window is the only shot.
The real standout, the one that's got me a little excited, is the morning of Tuesday the 28th. The wind drops right out, going glassy from the WNW at just 5 km/h. The swell is a solid 5ft from the NW with a period of 9 seconds, and the combined energy is a healthy 328 (moderate). The forecast says "expect good surf conditions." This is our window. Get down to Cogumelo for a Tuesday morning session. The swell direction (NW) is not the optimum SW direction the guidance likes, but with glassy conditions and a decent pulse, it'll be clean and fun. Keep in mind, this spot is fairly consistent and exposed, but it can get crowded, so get in early.
After that, it's back to the doldrums for a bit. We get a few days of tiny, weak swell again with onshore wind. Then there's a little spike on the 3rd of August (Monday) with 4ft of NW swell and 334 energy, but the wind is a cross-shore from the NNW at 20 km/h, which should keep it from being too choppy, at least. The morning of the 4th (Tuesday) has 5ft of NW swell and 257 energy, with a light cross-shore, but it's only rated as "marginal." The afternoon of the 4th gets messy again.
And then, for the long-range – lookin' out to Wednesday, the 5th of August, we have another promising glassy morning. The wind is 5 km/h from the WSW, glassy, with a 5ft NW swell. The period is a short 7 seconds, but the energy is 236 (moderate). It's a bit of a gamble this far out, but if it holds, it could be a very clean, fun morning. The swell is over 5ft, so it might be too much for beginners, but the glassy conditions will make it smooth.
So, to sum it up: the best on offer is Tuesday morning the 28th of July for the glassy conditions and solid pulse. The second promising window is the morning of Wednesday the 5th of August, but that's a long way off, so keep an eye on it. The rest of the time, the wind is just too messy for the swell we've got.
Rusty.

Information about the Cogumelo Surf forecast
The above surf forecast table for Cogumelo provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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. If you surf the same spot (Cogumelo) 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 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. 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.
