The Lowdown
G’day, Rusty here. Let’s get straight into it for Guarda do Embau – this river mouth setup has a bit of everything over the next couple of weeks, and the best windows are definitely worth your time.
We kick off on Thursday the 10th and Friday the 11th with waves around 3 ft to 4 ft, but the wind’s either cross or cross-off, and the periods are short or mixed. It’s small and average – nothing to write home about. The water temp feels about what you’d expect for this time of year. Saturday the 12th sees a real spike with swell hitting 7 ft from the south, period 9 seconds, and a combined energy of 1234 – that’s properly chunky. But the wind is a moderate 25 km/h cross-off in the morning. The afternoon turns to dog food with onshores.
Now, the standout arrives on Tuesday the 15th. Early morning is pure gold: glassy-clean vibes with a light WSW 5 km/h cross-off breeze, wave heights around 6 ft from the east with a 9-second period, and combined energy of 767. That’s a solid, clean, fun wave for intermediate and experienced surfers. The river mouth setup will handle that east swell well. Crowds are possible here sometimes, but early bird gets it. This is your best call in the first week.
Wednesday the 16th is big again with 7 ft to 7 ft south swells and moderate cross-shore wind – a bit raw, better for stronger paddlers. Not the cleanest but plenty of push.
Thursday the 17th morning bounces back nicely: 5 ft from the SSE, period 12 seconds (long period groundswell), light N 10 km/h cross-off, combined energy of 701 – clean and lined up. The long period means it’ll wrap into the river mouth nicely. Another top session.
Friday the 18th morning is the other real standout: clear sky, light N 10 km/h cross-off, 5 ft from the NE, period 8 seconds, and combined energy of 888. That’s a punchy, clean little wave that’ll have banks working. Again – crowds are a possibility, but it’ll be worth sharing the lineup.
After that, the second week calms down. Saturday 19th and Sunday 20th see smaller stuff around 3 ft to 5 ft, mostly with side or cross-on wind – not bad but nothing special. Monday 21st morning is glassy with N 0 km/h and 3 ft from the south, period 13 seconds – that long period groundswell will roll in clean but small. It’ll be a cruiser session for logs or mid-lengths.
Tuesday 22nd to Thursday 24th are mostly average: small waves, moderate to fresh cross-shore winds, and low energy. Friday 25th morning finishes the window with a bang: 7 ft from the east, period 9 seconds, combined energy of 803, and a light NNW 10 km/h cross-off breeze. Clean and chunky – a great way to end the run.
Overall, the best sessions are Tuesday 15th morning, Thursday 17th morning, and Friday 18th morning – these are your standouts. Get on it.
Rusty out.
