The Lowdown
G'day, I'm Rusty, and here's the surf outlook for our region.
We're looking at a pretty average start to the forecast period. The first few days are a bit of a write-off, with small, weak swell and poor conditions. The real action starts to build from the end of the first week and into the second, with a couple of standout windows.
The water temperature at Guarda do Embau is sitting at 66°F, which is spot on for this time of year, no surprises there.
The first real glimmer of hope comes on Sunday, August 23rd in the morning. It's a glassy morning with a moderate south swell at 5ft, a period of 11 seconds, and a combined wave energy of 610. The wind is dead calm, making for some very clean surf. It's a solid option for a weekend paddle.
Monday, August 24th in the morning is a standout for the more experienced crew. The swell is a solid 8ft from the south with an 11-second period and a massive combined energy of 2623. That's a lot of power. The wind is a clean cross-offshore from the southwest, so the conditions will be clean. This is a proper session, but at that size, it's definitely for the experienced surfer.
Tuesday, August 25th in the morning is another beauty. The swell drops a touch to 6ft from the south-southeast, but the period extends to 12 seconds, giving it plenty of punch. The combined energy is 978. With a light north wind giving a clean cross-offshore, this is prime conditions for that river mouth.
Looking further out, the second week has a few more promising windows. Monday, August 31st in the afternoon is a real highlight. The swell is 7ft from the south-southeast with a 13-second period and a combined energy of 1607. The wind is a light westerly, almost glassy, creating excellent conditions for experienced surfers. It's a long-range call, but it looks like a ripper.
The rest of the days in the second week are a mix of clean morning sessions with smaller, less powerful swell, so keep an eye on the daily forecasts.
