Guarda do Embau Surf Forecast and Surf Report

Alright, Rusty here, let's talk about what's on offer at Guarda do Embau. It's a river mouth setup, beginner-friendly, and it's exposed to the south-east. This stretch usually fires off that direction.

The water temp is running about average for this time of year, so nothing wild there. Wetsuit-wise, you'll know what to wear.

We've got a bit of a slow start, but things kick off on Wednesday, September 9th. First light is glassy, with a clean 3ft SSE swell pushing in. The energy is moderate (429). It's small but clean and that's a nice way to start the day. That afternoon, the wind swings cross-onshore and the vibe gets a bit messy, so make the morning session.

Thursday, September 10th is where it starts to get interesting. Morning brings a crisp 3ft S swell with a clean cross-off breeze. Then, the afternoon is the standout of the first week: 3ft from the SSE, period stretching out to 15 seconds, and a cross-off wind keeping it clean. The energy jumps to moderate (593). That's a long-period groundswell, so expect some proper shaped waves with long lulls between sets. It'll be a joy on this river mouth.

Friday, September 11th stays clean but the swell gets short period and jumbled. The morning has 4ft from the NE with a period of only 8 seconds, so it'll be a bit fat and weak, best left for the longboarders.

Then we get a spike. Saturday, September 12th ramps up. The morning is 8ft from the S with strong energy (1048). It's clean but at that size, it's getting into expert territory for a river mouth. The afternoon though, the swell hits 10ft from the S with a massive energy reading of 2803. That's powerful stuff, and the note says it's predicted to be too big for the break. This setup looks more interesting for kite surfing than paddle surfing at that size. Only the bravest and most experienced should even look at it.

Sunday, September 13th drops back to a still-chunky 6ft from the SE, but the wind is onshore and rain is around. Not a good look.

Monday, September 14th starts flat and rainy, but the afternoon saves the week. Glassy conditions return with a clean 3ft S swell, 11-second period, and moderate energy (513). For a Monday session, that is a treat.

Tuesday the 15th and Wednesday the 16th are average, with the wind adding chop.

The next real highlight is Thursday, September 17th. Morning session has a clean 5ft from the SSE with a 13-second period, giving strong energy (913). That's a solid, clean groundswell with a nice cross-off breeze. The shape will be there, but expect some crowd if the locals smell it.

Friday, September 18th finishes the week nicely. The afternoon goes glassy again, with a 3ft SSE swell on 11-second period, energy at 356. Small, clean, perfect for a relaxed session on the river mouth.

Saturday the 19th and Sunday the 20th are small and weak, but Monday, September 21st offers a glassy morning with 4ft from the east, 8-second period. It's weak period, but the glass makes it surfable.

The final run kicks off on Wednesday, September 23rd. Morning is clean with a 6ft ENE swell, 7-second period, and energy at 577. It's short period, so not the best shape, but the size and clean wind make it worthwhile for a quick paddle.

There's a six-day gap at the end with nothing better than ordinary conditions. So, the standout pick? Thursday afternoon, September 10th and Thursday morning, September 17th. The first one for the long-period perfection, the second for the solid, clean power. Get out there and make the most of it.
