The Lowdown
Alright, Rusty here with a look at the next couple weeks. And I gotta tell you, it’s a rough go. We’re talking about Cogumelo, and the forecast has a big fat zero on it for a long time.
There’s a big gap at the start with nothing to recommend. From Thursday, July 23rd, all the way through to the morning of Thursday, July 30th, it’s a total loss. The wind is mostly cross-onshore, and the swell is tiny, weak, and short-period. The combined energy readings are low, in the 40s and 60s.
We finally get a slight glimmer on the morning of Thursday, July 30th. The wind turns light from the north-northeast, going cross-offshore and making it clean. We’re looking at a tiny 3ft NW swell at 7 seconds, with weak energy (90). It’s surfable, but only just. If you’ve got a log or a foil, you might scratch out a few grovelers. This is your best shot, and it’s not saying much.
After that, it’s back to the same old story. The wind goes onshore again, and even when the swell bumps up to 5ft from the NW with moderate energy (405) on Sunday, August 2nd, it’s too chopped up by the fresh cross-onshore breeze to be any good. The whole run stays in that "poor" category.
Honestly, this is a tough one. It’s a long, flat, windy spell. For such a consistent spot, a run this poor is rough, but it’s what we’ve got. Forecasts can change, but right now, it looks like one for checking the wind apps rather than the surf.

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.
