The Lowdown
Alright, this is Rusty, and I've gotta be straight with you. The outlook for Cogumelo over the next couple of weeks is a tough one. We're looking at a long, frustrating stretch of onshore and cross-onshore winds that are just going to chop things up. The good news is, there's a light at the very, very end of the tunnel, but you're going to need some patience.
For the first week, from Friday the 17th right through to about Sunday the 26th of July, it's a write-off. The wind is howling out of the NW and NNW, keeping the surf small and messy. Swell heights are hovering around 1 to 5 ft, but with a short, weak period of only 4 to 6 seconds and a moderate cross-onshore breeze, the wave energy is low. It's not just poor; it's choppy, lumpy, and not worth paddling out for.
There's a slight glimmer on the 27th of July, but it's mostly flat. Then, the late July transition kicks in. The 28th of July shows a pulse of 6 ft NW swell with a more respectable 8-second period. But the wind is still cross-onshore from the SSW, so the forecast is marginal at best.
Now, hold onto your boards, because the real standout finally arrives. On the morning of Thursday, the 30th of July, things come together. We get a solid 7 ft groundswell from the NW with a 9-second period, and the energy is pumping. But the key here is the wind: it's glassy. That's right – dead calm, slight air from the SSW. That's a major positive, meaning perfectly clean, peeling waves. This is a punchy size, so it's going to be an intermediate to expert session. It's a rare, promising window.
After that, it looks like the window slams shut again for Friday and Saturday.
So, when we zoom out, there’s one clear highlight: the morning of Thursday the 30th at Cogumelo. That’s your session if you can make it. For everything else, save your energy, because a blank run like this is pretty normal for the area. Forecasts can always shift, but right now, be ready to wait.

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.
