Cogumelo Surf Forecast and Surf Report

Alright, let’s get into it, this is Rusty.

Alright, listen up. We’ve got a bit of a slow starter on our hands here at Cogumelo. The first couple of days are pretty average, but don’t write it off just yet—there are some serious highlights waiting in the wings if you’re patient. The stars really align for a couple of sessions that’ll make it all worth it.

The water's sitting at 66°, which is a good 4° colder than usual for this time of year. That’s a noticeable chill, so you’ll want a decent suit.

Saturday, September 12th is a write-off. The morning has a tiny 3 ft NW swell with only 7 seconds of period and weak energy (101). The wind is cross-off from the NE, but it’s just not happening with quality. By the afternoon it gets even worse with onshore wind and messy conditions.

Sunday the 13th looks a bit better. The morning has the same 3 ft NW swell, but the period picks up to 10 seconds and there’s moderate energy now (265). Light cross-off wind from the NE will keep things tidy. It’s surfable, but not a standout. The afternoon turns sour as the wind swings onshore.

Monday the 14th is where it starts to get interesting. The morning session is clean and glassy with a NNE breeze at just 3 mph. A 4 ft NW swell with a 10-second period and moderate energy (244) will give you some fun, clean waves. This is a nice, mellow option for intermediates.

Now, here’s the first real standout. Monday, September 21st. The morning is absolutely firing. Glassy conditions, a WSW breeze so light you can barely feel it. A solid 6 ft NW swell with a very long 15-second period is pumping through, and the energy is huge (1471). This is groundswell with serious power, and the long period means it’ll be better shaped, though at a beach break it might stand up a bit straight. For experienced surfers, this is the pick of the whole forecast. The afternoon looks marginal with onshore wind.

Hot on its heels, Tuesday, September 22nd morning is another gem. Again, glassy, this time with a light ENE breeze. Another 6 ft NW swell, this time at 13 seconds, with energy still massive (1218). This is another top-tier session for the experienced crew.

Friday, September 18th morning has a clean, fun 6 ft NW swell (9 sec period, 500 energy) with cross-off NNE wind. It’s a good, clean option for intermediates.

Wednesday, September 23rd morning offers a slightly smaller but glassy rip with a 5 ft NW swell (11 sec period, 471 energy). It’s a solid mid-range option for a clean morning surf.

After Thursday the 24th, things drop off a cliff. The swell fades right out, and the energy flatlines. There’s nothing worth paddling out for from the 25th right through to the end of the period on the 27th. A long, quiet finish to the outlook.

So, to wrap it up: the mornings of Monday the 21st and Tuesday the 22nd are your absolute best bets for clean, powerful, glassy groundswell at Cogumelo. Don’t miss them. Everything else is either average or blown out.

Rusty.
