The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
We’re talking about Guarda do Embau (Brazil) – a river mouth setup that’s consistent and beginner-friendly. The water’s sitting at 66°, which is pretty much right where you’d expect for this time of year, nothing weird going on there.
The first few days are a bit of a write-off, to be honest. Thursday the 3rd kicks off with a 5ft SE swell and a moderate breeze from the north, but it’s cross-off, so the morning is clean. The energy’s moderate (566). Still, the scores are low – it’s a bit marginal. That afternoon and Friday look poor, with cross winds and chop.
Saturday the 5th is a washout. We get a little 4ft S swell, but it’s short period at 8 seconds, and the wind is cross-shore with rain. Not worth paddling out.
Sunday the 6th gets a bit chunky in the afternoon – 7ft from the south – but the wind is a fresh 19 mph from the south, whipping up a lumpy cross-chop. That’s kite-surfing weather, not paddle-surfing weather. The energy is moderate (710).
Now, let’s talk about the good stuff.
Monday morning the 7th is a real standout. The swell drops to a solid 7ft from the SSE, with a 9-second period, and the wind is a light 6 mph from the WSW – that’s cross-off and clean. Combined energy is moderate (686). This is the best on offer in the first week. The size is pushing into the intermediate zone, but it’s clean and the river mouth should handle it well.
Wednesday morning the 9th is another beauty. Clean, clear skies, a light 9 mph north wind blowing cross-off, and a 6ft ENE swell at 7 seconds. That’s a short period, so it’ll be a bit choppy on the face, but the energy is moderate (665) and the conditions are clean. A fun morning surf.
Then there’s a bit of a quiet patch. Things get messy with onshore winds and rain through Thursday and Friday the 10th and 11th. Saturday the 12th is a write-off too.
Monday the 14th has potential. A 6ft S swell, cross-off wind from the north at 6 mph, clean conditions. The energy is moderate (855). Might be a bit lumpy with the 8-second period, but it’s workable.
The real long-range standout is shaping up for Friday the 18th of September. That afternoon, we’ve got a 6ft SSE swell with a 14-second period – that’s a proper groundswell, long period, lots of energy. The wind is a gentle 9 mph from the SW, cross-off, and it’s clean. The combined energy is a strong 1437. This is the best session of the whole outlook. The long period will mean the river mouth will be a bit more lined up and the sets will be wider apart, making it easier to get out. If you can hold out for that, it’s the one to aim for. The morning of the 18th is also good, with a 6ft SSE swell at 15 seconds and clean, cross-off wind.
So, overall, the best windows are Monday morning the 7th for a clean, solid session, and the real prize is Friday the 18th with that long-period groundswell and glassy conditions. It’s a promising outlook, but the first week has a lot of chop to sit through.
Rusty.
