The Lowdown
G'day, Rusty here. Looking at the 16-day window for Guarda do Embau, it's a bit of a slow burn, but patience will pay off.
The first few days are pretty grim. From Wednesday the 19th through to Friday the 21st, it's all small, messy, weak energy and the conditions are just not worth paddling out for. You'll have to sit through a few days of nothing much.
Then, Saturday the 22nd morning is where things start to wake up. We've got a clean 6ft swell from the SSW, with a light offshore breeze making it look clean. The combined energy is a solid moderate 763. It's a river break, so it handles swell well, but be aware that this spot can get crowded sometimes. The water temp is about average for the time of year.
That Saturday arvo, the wind turns onshore and it chops up quickly, so get your session in early.
Sunday the 23rd morning is a bit of a mixed bag. There's a 5ft S swell with a long 11-second period, which is a groundswell, and the combined energy is 521. The wind is light cross-shore, so it could be workable, but it's described as marginal. The longer period might make it a bit tricky at the river mouth, but it's worth a look.
The standout window is that Monday the 24th. The morning shows a solid 8ft SSE swell with a very long 13-second period and massive combined energy of 2359, which is strong. That's expert territory for sure, and with a cross-shore light breeze, it'll be a big, powerful wave. The afternoon keeps it up with 8ft and a 14-second period, still massive energy at 2085. This is the best on offer, but it's a serious wave, not for the faint-hearted.
After that, the middle of the week from Tuesday the 25th to Wednesday the 26th sees the swell drop back to 5ft to 6ft, mostly clean but with some cross-offshore winds. It's surfable but not as clean or powerful as Monday.
Thursday the 27th afternoon offers a surprise with a clean 4ft wave from the ENE and offshore winds – that's a real glassy session for the more experienced.
The end of the run into the first week of September looks small again, with mostly poor conditions and weak energy. There's a glimmer on Monday the 31st of August with a clean 3ft SSE swell, but it's a small wave.
So, to sum it up: the best of the window is without a doubt Monday the 24th of August for the big swell hunters, but for a cleaner, more manageable session, Saturday the 22nd morning is your best bet. Keep the weekend free.
Rusty.
