Table - best surf conditions forecast for Cogumelo over the next 16 days.
Alright, so we’re talking Cogumelo, and the first week is a bit of a write-off. You’re looking at a dry spell from Thursday the 9th until Sunday the 12th, with virtually nothing to ride. The wind’s all wrong and the waves are tiny and messy.
The first real chance comes on the morning of Sunday July 12th. The wind goes dead calm, glassy conditions, and we see a small 3ft swell from the WNW with a combined energy of 181 (moderate). It’s not going to blow your mind, but it’s clean enough to get wet.
Then it’s back to poor conditions for over a week. Cross-onshore wind, choppy water, and heights between 2ft and 5ft – none of it worth chasing. The period is short, mostly 6-7 seconds, so the waves are weak.
Now, here’s the big one. On Thursday July 24th, the morning is an absolute standout. Glassy conditions with a clean 5ft groundswell from the NW, and the energy is a strong 387. The water’s about 68°F, which is normal for this time of year. This is the best wave of the whole forecast.
Cogumelo is exposed to SW swell for its best direction, so the NW is not ideal, but with no wind and that kind of power, it’s going to be the most fun you’ll have in this 16-day window. Keep an eye out for crowds – they show up often here. For the intermediate surfer, that 5ft is a solid session.
After that morning, it drops back into onshore junk, so make sure you’re on it early on the 24th.

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.
