The Lowdown

Alright, let’s get into it. This is your local surf reporter, Rusty, and I’m looking at what we’ve got on the cards for Guarda do Embau.

The opening stretch is pretty flat and messy. Thursday and Friday morning start off with weak, short-period slop, nothing worth paddling out for. The first real glimmer of hope shows up on Friday morning, the 21st. It’s small at 4ft on a short 8-second period from the SSW, but the wind is light and cross-offshore out of the SW, which will leave the surface looking clean. It’s not big, but for a bit of fun on a log, it’s doable.

The swell builds through Saturday, with a 8ft southerly swell rolling in on the 22nd. That’s a solid drop, but the wind is a cross-shore mess and the period is still short, making it pretty lumpy. Not ideal.

Now, if you’re an experienced surfer, Monday morning, the 24th, is your standout. We get a solid 8ft swell from the SSE with a very long period of 16 seconds. That’s proper groundswell, the kind that packs a punch and draws power into the river mouth. The combined wave energy is a massive 3374, and the wind is glassy – completely dead. This is big and clean, with some real grunt. The only catch is that at this size and with that long period, the wave will be powerful and best suited for experienced surfers, especially on a river break.

By Tuesday the 25th, the swell drops to 6ft, but it’s still from the SSE. The period is a healthy 13 seconds, and the morning wind is light, cross-offshore out of the north. That means clean, well-shaped lines. The water temperature is sitting about average for this time of year, nothing unusual to note.

As we head towards the end of the month, the energy fades. By the 29th, we’re back to smaller, knee-to-waist high swells from the ENE with a short 8-second period. The winds look cleaner in the mornings, but the surf is just too weak to get excited about.

From the 30th and through the beginning of September, it’s a disappointing run. Strong cross-shore winds and short-period swell mean the water will be choppy and confused. There’s a small pulse around the 1st of September, but the wind is wrong and the quality drops. A real dead spell.

So, overall? The one true standout is Monday morning, the 24th. If you’re an experienced surfer and you can handle a strong 8ft groundswell, that’s your session. Friday the 21st and Tuesday the 25th offer smaller, cleaner windows for a more relaxed paddle.

See you out there.
