The Lowdown

Alright, let’s get stuck into the outlook for Cogumelo. It’s a fairly consistent spot that’s exposed to the swell, and it works best with a good SW direction. The water temperature is sitting at 68°, which is about average for this time of year, so no surprises with the wetsuit choice.

Honestly, the next week and a half is pretty grim. We’ve got a long stretch of poor surf conditions from now right through to the 12th of August. There’s a little bit of energy in the water, but the wind is mostly cross or cross-on, and the swell is tiny, never really getting above 1 ft to 3 ft, with short periods around 6-9 seconds. It’s just not doing anything worthwhile. The combined energy stays weak, mostly under 100 (48-99 range), so it’s a flat spell. You’d be better off taking a break or doing some maintenance on your board.

The first sign of something surfable is on the morning of Thursday, the 13th of August. The wind turns light and cross-off, giving us some clean conditions, and the swell bumps up to 3 ft from the WNW with a 9-second period. The combined energy is moderate at 143, but it’s only described as “surfable waves but very ordinary conditions.” It’s not a standout, but it’s an option if you’re desperate.

The 14th and 15th stay marginal. The swell is around 3 ft to 5 ft, but the wind is off or onshore, and the conditions are messy. The morning of Sunday, the 16th of August, is the best of the first two weeks. The wind is light and offshore from the ENE, the swell is 3 ft from the NW with a 9-second period, and the combined energy reads 172. The report says “clean,” and that’s a proper window. It’s only 3 ft, so it’s not going to pump, but it will be clean and rideable. After that, it drops off again into flatness.

Now, the real standout is Friday, the 21st of August. The morning session has a solid 7 ft swell from the NW, with a 9-second period and a combined energy of 735, which is strong. That’s a proper push. The wind is gentle cross-shore from the NNW, so there’s only a slight chop. This is a big day, but 7 ft is getting into expert territory, so it’s not for the groms or beginners. The swell direction is NW, which is a bit off the optimum SW, but with that much energy and cleanish wind, it’s the best on offer by far. The afternoon gets choppy again, so hit the dawn patrol.

To sum it up: the first 12 days are mostly a write-off. The 16th is a clean, small window. The 21st is the one to circle on the calendar for the experienced crew.

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.
