Prainha Surf Forecast and Surf Report

Alright, let’s get stuck into it. The next couple of weeks are looking pretty quiet for the most part, so we’ll have to bide our time. There are a few pulses of energy, but we’ve got to be smart about when to paddle out. We're looking at a long dry spell to start, then a couple of windows where it might just come together.

To kick things off, we’re looking at the next few days with pretty small surf. Come Thursday the 6th of August, it’s tiny—around 2ft with an 8-second period and weak energy (64). There’s a bit of offshore wind in the morning, which is nice, and the water is sitting at 68°, a touch warmer than normal for this time of year, but honestly, it’s not worth getting wet for. That kind of small, short-period stuff is messy and weak.

Those weak conditions drag on through Friday and into the weekend. Waves stay below 3ft, energy is weak to moderate at best. Saturday the 8th sees a bit of a longer period start to roll in, but it’s coming from the SE, which is cross to cross-on at Prainha. It’s not going to be any good.

Then it goes pretty flat again. From Sunday the 9th through to Tuesday the 11th, we’ve got a lot of nothing – the swell drops away and it’s just small, weak leftovers. Sunday morning has a bit of period, but it’s cross-shore and blown out. There’s a gap there of a few days where you’d be wasting your time.

We finally get a proper window on Wednesday the 12th of August. The morning stays glassy with light offshore SW winds. The swell only nudges up to 3ft, but the period has stretched out to 12 seconds, and it’s from the SE, which is a better angle. The energy (150) is pushing into moderate territory. It’s surfable. By the afternoon it’s a bit cleaner with an offshore breeze, and the swell bumps to 3ft with a 13-second period and the energy (203) is building. This is the first real sign of life.

Thursday the 13th is a bit of a letdown – it backs off again. It’s clean, but small. The real standout, though, is Friday the 14th of August. We wake up to offshore WSW winds and a clean 2ft SE groundswell with a long 15-second period, and the energy is really starting to move (241). This is the kind of long-period groundswell that Prainha can handle, and with offshore wind, it’s going to have some shape. The afternoon picks up a bit of size to 4ft, but the period drops and the wind swings more SSW and strengthens, making it a bit messier. The morning is your window.

Now, that swell runs out of puff pretty quickly into Sunday the 16th. The morning of the 16th sees a push of 7ft, but it’s short-period E swell (8 seconds) and cross-shore. That’s a step up in size, but it’s going to be a jumbled mess – not a surfer’s friend. There’s too much short-period energy to be good. The swell stays overhead for a couple of days, into the 17th and 18th, but it’s all east windswell, cross-on and choppy. Not good.

We see the last little flutter of hope midweek. On Wednesday the 19th, it’s glassy again in the morning with a clean 3ft E swell, but the period is a short 9 seconds. It’s surfable but not special. After that, it just kind of fades out and gets messy again through the end of the forecast period.

So, to be honest, if I were you, I’d be circling Friday morning on the 14th of August. That’s the standout – clean, offshore, and with that long-period groundswell pushing through. The weekday morning on the 12th could be a fun little pre-game, but Friday is the one. Everything else is either too small or too messy. It’s a long wait for the good stuff, so keep the board waxed and be ready to go when the windows open.
