Prainha Surf Forecast and Surf Report

Alright, surfers, Rusty here. Let's look at what Prainha has cookin' for us over the next couple of weeks. It's a bit of a mixed bag, but there are a few windows of opportunity if you're patient and picky.

The water is runnin' a touch warmer than usual for this time of year, sittin' around 68°, which is a nice bonus to start with.

We kick things off Wednesday, August 12th, with a tiny pulse of 2ft SE swell. The energy is pretty weak (145), but the wind is dead glassy. It will be surfable, but really, it's just a warm-up.

Things get a whole lot more interesting on the morning of Thursday, August 13th. That same 2ft from the SE is carrying some serious grunt, with a very long 16-second period and moderate energy (240). The wind is a clean cross-offshore from the south, so expect some clean, lined-up waves. This is a standout window for the good surfer on a longer board. The long-period groundswell means it’ll be a bit more peaky at a beach break like this, but the quality looks great.

Friday, August 14th, sees the swell drop off, but we get glassy conditions both morning and afternoon. It’s small, but clean.

Now, brace yourselves. From Saturday, August 15th, through to the morning of Tuesday, August 19th, we’re in a rough patch. The wind turns onshore and cross-onshore, and the swell gets a short, weak period with combined energies that just look messy. It’s a no-go for paddle surfing; frankly, with those winds, the setup looks more interesting for kite surfing than a paddle session.

The morning of Wednesday, August 19th brings another glassy calm, but with only 3ft of weak E swell. Clean, but small.

We then go into another long, dull run from the afternoon of the 19th through the 22nd. Small, onshore, and forgettable.

But hold on to your boards, because a real standout is brewing for later on. Sunday, August 23rd, is our top call. The morning is showing a solid 4ft of SE swell with a nice 12-second period. The combined energy is a solid 442, a big jump. And the best part? Glassy conditions from a light WSW wind. This is the real deal – clean, strong, and with some push. It’s still fine for most experienced surfers, but if you’re a beginner, that 4ft might be a bit of a handful.

Following that, Monday morning, August 24th, and Tuesday morning, August 25th, also offer up clean conditions with light offshore or cross-offshore winds and decent 3ft SE groundswell. Good follow-up sessions, but the 23rd is the one to circle.

The outlook fades again after Tuesday afternoon as the wind picks back up. So, keep your eyes on that Sunday the 23rd for the best chance of some memorable waves with no fuss.

Rusty.
