The Lowdown
Alright folks, Rusty here. Let's take a proper look at what's cookin' at Guarda do Embau over the next couple of weeks. This spot's a classic river mouth setup, and it's known for being a friendly wave for the beginners out there.
Right off the bat, we've got a bit of a slow start. The first few days are a mixed bag, with only small windows of decent surf. The water temp is sittin' pretty much where you'd expect for this time of year, nothing wild to report there.
On Thursday, September 19th, things are a bit lackluster. The morning offers some clean, 3ft cross-off swell from the south, but the energy is on the weaker side (250). It's surfable, but not gonna set the world on fire. The afternoon gets blown out real quick with a strong cross-on shore.
Then we've got a real standout: Sunday, September 20th. Get your gear ready. The morning is looking excellent for experienced surfers. We've got a solid 8ft swell pumping in from the northeast, packing a ton of punch - we're talkin' strong wave energy (1333). The wind is light and clean off the land, making for some proper, clean waves. This one's a little meaty, so if you're still finding your feet, maybe give this one a miss. The afternoon gets messy with a building cross-shore chop.
After that, the surf backs off for a few days. Monday, September 22nd is a nice little rebound. The morning is glassy, dead calm with a clean 5ft ENE swell (292). Perfect conditions for a long, fun session on the longboard or a fish. The afternoon stays clean with glassy conditions, too.
The week ahead looks pretty unsurfable from Tuesday, September 23rd through to the end of that week, with onshore winds and small, choppy waves. The combined energy drops right off, so it's a good time to wax the quiver and wait.
Now, keep your eyes peeled for Thursday, September 25th. The morning brings a very long-period groundswell from the SSE, hitting 5ft. The energy is significant (834), and with a period of 14 seconds, these waves are gonna have some real push. The wind is offshore and light, keepin' the faces clean. This long-period stuff can be a bit tricky on a beach break, but a river mouth like Guarda do Embau can handle it beautifully. This is a seriously promising session.
There's another small, clean window on Saturday, September 27th, with a small 2ft SSE swell (238) and light offshore winds, but the energy is minimal.
The big question mark is at the very end. Tuesday, September 30th shows a wet morning, but the afternoon of Wednesday, October 1st goes glassy with a solid 8ft south swell (869). Could be an absolute ripper for the big-wave crew.
And finally, on Thursday, October 2nd, the forecast hints at a 10ft south swell (2694). That's a massive amount of energy, but the file is crystal clear: it's predicted to be too big for this break. That one's for the mad dogs and kites, not for a standard paddle session.
Keep an eye on that Sunday the 20th and Thursday the 25th. Those are your best bets for a good time.
Rusty out.
