The Lowdown
G'day, Rusty here, looking at the surf for Guarda do Embau over the next couple of weeks. It's a bit of a mixed bag to be honest, but there are a couple of windows that'll get the heart pumping.
Right now, the water is sitting at 66°, which is pretty much spot on average for this time of year, so no surprises there.
The first few days are a bit of a write-off. Friday the 4th and Saturday the 5th are just small and messy, with onshore winds. Not worth paddling out for. Saturday afternoon does tidy up a little with some clean conditions, but the swell is only 3ft from the south, so it's more of a longboard session if you're desperate.
The first real standout window kicks off on Tuesday the 8th. Tuesday morning we've got a clean 4ft SSE swell (354 energy) with light offshore winds. That's a nice combo. Then Wednesday the 9th morning is even better – 6ft from the ENE, clean conditions, and moderate wave energy (508). That's a solid offering for the river mouth. The direction is a bit off the optimum, but the clean conditions and waist-to-chest high waves will be fun.
Things get a bit more interesting as we head into the second week. We've got a long gap of very ordinary surf from the 11th to the 13th, but then on Monday the 14th, we start to see a pulse. Monday afternoon shows a 6ft S swell with a 10-second period and clean conditions (938 energy). That's a decent groundswell for the river.
The real standout, however, is shaping up for Thursday the 17th of September. We're looking at a solid 7ft SSE swell with a very long 16-second period, and the combined energy is a massive 2763. That's proper groundswell. The wind is cross-shore, not perfect, but at that size and period, it'll be pumping. This is for experienced surfers only – 7ft is too big for beginners, and that long period will make it wall up and run. It's a bit of a gamble that far out, but if it comes together, it'll be the best of the whole forecast.
The following morning on the 18th still has some size – 4ft SSE with a 13-second period (885 energy) – but the winds get a bit more onshore, so it won't be as clean.
Overall, the best bet is Wednesday the 9th for a clean, fun session, and keep an eye on Thursday the 17th for a big, powerful day if you're up for the challenge.
Stay stoked,
Rusty
