The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Honestly, it’s a pretty grim stretch ahead at Cogumelo. We’ve got a long, dry spell of poor conditions before anything worth paddling out for shows up. From the start of the outlook on the 27th of July, right through until the 10th of August, it’s mostly just small, weak, and messy. The wind is a constant problem – mostly onshore or cross-onshore from the west and northwest, chopping everything up. The combined swell energy is low, often under 100 (weak), and the swell heights mostly hang around 1ft to 3ft with short, weak periods. There’s a tiny window on the 29th of July Wednesday morning with glassy conditions and a 2ft NW swell, but with a period of 9 seconds and combined energy of just 94 (weak), it’s barely a ripple. The water is sitting at 67°, which is a bit colder than normal for this time of year.
The real story, if you can call it that, arrives on the 11th of August, Tuesday morning. After a solid week and a half of nothing, we finally get a glimmer of hope. The wind swings around to a light ESE at just 3 mph, turning the ocean glassy. That’s the big win here. The swell is 6ft from the NW with an 8-second period, and the combined energy jumps to 390 (moderate). That’s a decent pulse, but it’s a short-period swell, so it’ll be a bit crumbly and won’t have that groundswell punch. Still, the glassy conditions will make it look a million times better than anything else in the forecast. This is really the only standout, and it’s a long way out, so keep your fingers crossed the forecast holds. If you’re a beginner, that 6ft might be a bit much, but for the rest of you, it’s the best we’ve got.
The afternoon of the 11th goes back to onshore junk, so you’d want to be out there early. That takes us right up to the end of the 16-day window. It’s a tough run, but it only takes one good glassy morning to make it all worth it. Keep an eye on that 11th of August.
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.
