The Lowdown
Alright, Rusty here. Let's have a look at what's coming down the pipe for Guarda do Embau.
This is a classic setup right here – a river mouth break that's all about consistency, exposed to the swell. We’re looking at a pretty solid run of surf over the next couple of weeks, with the ocean kicking up some proper energy. The water temp is going to be about average for this time of year, so nothing too wild there.
We kick things off this Friday morning, the 21st, with a clean 5ft swell out of the SSW. The light cross-offshore breeze will have it looking tidy, and the wave energy is sitting at a moderate 449. It’s not huge, but it’s a fun, clean start for the beginners. Definitely one to get the board-wax warm.
Saturday the 22nd sees a jump in size. The morning has a 8ft swell from the south, with wave energy blasted up to 1734 – that’s strong. But there’s a cross-shore wind on it, making it a bit lumpy. At that height, it’s getting a bit too much for beginners; you’ll want some experience under your belt. It holds through the afternoon, dropping slightly to 7ft.
Sunday the 23rd is a bit of a letdown. Still plenty of water moving, with a 6ft long-period groundswell at 12 seconds and energy at 789, but the winds are messy, pushing cross-onshore and making it choppy. That long period is better for a point break than a river mouth, but the wind is the main problem here. It looks more like a day for the kite surfers than us paddle guys.
Now, Monday the 24th is where it gets interesting. This is a standout. The morning pumps an 8ft groundswell from the SSE with a massive 4573 energy reading – that’s very strong. The period hits 16 seconds, a seriously long groundswell. The catch is it’s only got a light cross-shore, but that long period will want to jack up and could be tricky on the river mouth. This is expert territory, and big. Keep an eye on the tide.
Tuesday the 25th and Wednesday the 26th are your sweet spot mornings. We’ve got a perfect cross-offshore wind from the north, cleaning up a 6ft SSE swell (1447 energy). The conditions read as excellent for experienced surfers. The wind is light, the wave state is clean. This is the best on offer. If you can get out there those mornings, do it. Crowds are sometimes an issue here, so getting out early will pay off.
The rest of the week into the start of September gets a bit scrappy. There’s a pulse of NE windswell around the 28th with a short period, and plenty of onshore or strong winds. The 31st (Monday) has some heavy rain and a small 5ft clean-up in the afternoon, but it's not a burner.
We inch back up into the 6-8ft range around the 1st and 2nd of September, but the wind is mostly onshore or cross-shore fresh, making for poor surf. The real highlight in the second week is Thursday morning, the 3rd of September. We get another clean, cross-offshore morning with a 6ft SE swell (885 energy) and a nice 11-second period. The forecast says 'very good surf conditions'. That’s likely your best bet in that second week – promising, but it's a long way out so don't hold me to it just yet.
After that, the swell fades right out towards the 5th of September, dropping below 3ft and the runs are done.
So, to keep it simple: the absolute standouts are Tuesday the 25th and Wednesday the 26th mornings. Get on those. Monday the 24th morning is for the big-wave crew only.
Rusty out.
