Table - best surf conditions forecast for Cogumelo over the next 16 days.
Alright folks, Rusty here. Let’s get real about what’s coming up at Cogumelo. I’ve looked at the charts, and I’m calling it straight: there’s a long, dry stretch ahead. The first decent surfable day won’t pop up until Sunday morning, July 12th, and even then, it’s a pretty grim picture overall.
The pattern for the next two weeks is a flat, blown-out mess. We’ve got a solid 4-day gap right off the bat with no recommendations at all. From Wednesday the 8th through Saturday the 11th, the waves are tiny with weak energy – values hanging around 33 to 72 (km/h energy) – and the wind is a persistent cross-onshore, making everything a choppy, unappealing onshore slop. Water temps are sitting at 68°F, which is pretty much normal for this time of year, so that’s about the only thing not working against us.
The first real chance to get wet comes Sunday morning, the 12th. We’ll see a bump up to 3 ft of swell from the WNW, with a 9-second period, and the energy jumps to 180 (moderate). The wind is actually onshore, which is a big positive – it’ll be clean. The waves will be small, but it should be the best, most ridable session of the entire forecast period. Sunday afternoon stays rideable too, with 3 ft of swell, but the wind swings back onshore and the energy drops to 139.
After that, it’s a slow bleed back into nothing. The rest of the week is poor, with waves under 2 ft, and the wind is either onshore or cross-onshore. The energy stays weak to moderate at best. The only other time the swell even tries to flex is on Friday and Saturday the 17th and 18th, when we see 5 ft of swell from the NW, but the period is a short, weak 6 seconds, and the wind is a strong, messy cross-onshore (25 km/h). The energy hits 152 and 158, but with that wind and short period, it’s just a washing machine. Better suited for a kite than a paddle.
The standout, if you can call it that, is Sunday morning, the 12th of July. It’s the only window with clean, onshore winds and a small, rideable 3 ft swell. If you’re desperate, that’s your session. The long-range stuff from the 20th onward is a total write-off – tiny waves, no energy, and strong winds. Save your energy.
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.
