Cogumelo Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s on the cards for the coming weeks.

Right off the bat, it’s a slow start for the first few days. Thursday through Sunday, September 4th to 7th, we’re looking at small, weak swell with messy wind pushing in from the west and northwest. The surf is there but it’s pretty ordinary – small 2ft to 3ft stuff from the WNW and NW, with a period around 8 to 9 seconds – nothing to get excited about. The combined energy is low, in the 50 to 136 range, so it’s pretty weak. Winds are cross-off in the mornings but swing cross-on in the afternoons, so the mornings are the only clean window, though the waves are small. Friday the 4th morning is your best bet this weekend, but it’s still a marginal one.

Now, the first real standout comes Monday morning, September 7th. That’s when we get a nice pulse of groundswell. Swell from the WNW at 4ft, period jumping to 12 seconds, and the combined energy hits 532 (moderate to strong). The wind is cross-off from the NNE at 15 km/h, keeping it clean. Cogumelo is the break to be at that morning. The water’s running a bit cooler than normal – 67°F, which is about 3°F colder than average for this time of year, so grab a thicker wetsuit. That 12-second period means longer lines and better shape, and the sets will have a bit of punch. It’s a fairly consistent spot, and with a crowd that’s “often” around, you’ll likely have company, but the quality should be worth it. This is the best session on offer in the whole forecast.

After Monday morning, the wind turns ugly for the rest of the week. Tuesday through Thursday the 8th to 10th morning, the swell hangs in there at 4ft to 6ft from the NW, but the wind is onshore or cross-shore, making a mess of things. The energy is all over the place, but the poor surf quality is the story. The mornings of the 8th and 9th have cross-off or cross-shore winds, so it’s not totally hopeless, but far from the clean Monday morning.

We hit a flat spell from Friday the 11th through the 12th with tiny waves and low energy (12 to 75). Not worth paddling out.

Then we get another glimmer of hope. On Sunday morning, September 13th, a new NW swell of 5ft, 7-second period, rolls in with glassy conditions – wind from the north at 5 km/h. The combined energy is 338 (moderate). The shape will be a bit short-period, but the glassy surface will make it clean and fun. Early birds will get the best of it before the afternoon cross-on wind kills it.

The following Monday morning, September 14th, is also worth a look. A 4ft NW swell with a 9-second period, glassy conditions again, and 335 energy. That’s a solid, clean morning with better shape than Sunday. Again, the afternoon wind ruins it.

From Tuesday the 15th onward, the swell drops off and the wind stays mixed. The mornings of the 15th and 16th are glassy but small – 2ft to 4ft, with low to moderate energy. The 17th and 18th get blown out with fresh NW winds. The last few days of the forecast (18th–19th September) are just poor, with tiny, messy waves.

So, the clear standout is Monday morning, September 7th at Cogumelo – 4ft WNW groundswell at 12 seconds, clean cross-off wind, and solid energy. That’s your best chance for a proper session. The Sunday and Monday mornings the following week (13th–14th) are your backup, with glassy conditions and fun-sized waves.

Rusty.
