Prainha Surf Forecast and Surf Report

Alright, grab your board and listen up. Rusty here with the outlook for Prainha.

Alright, so this is a strange run, to be honest. The next few days are a mixed bag with some clean windows but nothing that'll get you firing out of bed. The real standout is way down the line, and that’s the one to keep an eye on. There’s a lot of "ordinary" conditions to wade through first.

The Early Days

Wednesday morning (12th August) is surfable but nothing special. We've got small 2ft swell coming from the SE with a 12-second period. The energy is weak (149), but the silver lining is the glassy conditions with a light NW wind. The water is at 68°, which is a touch warmer than usual for this time of year. That’s about it though, because that afternoon turns into a cross-on mess.

Thursday morning (13th August) is your early bright spot, but it’s a short one. The swell is still 2ft from the SE, but the period jumps to a very long 16 seconds. This is proper groundswell energy (239) and with absolutely no wind, it’s going to be glassy perfection. This long period will make for well-shaped lines at Prainha (exposed S-facing reef/beach break), though at this size it will be gentle. This is the best bet in the first week.

After that, the week drops off badly. Friday through Sunday looks poor. The wind is onshore or messy, swell gets shorter period and smaller. We’re looking at a blank run from Friday afternoon right through to Sunday.

Monday morning (17th August) brings another glimmer. We get 4ft from the E with a short 8-second period, but the wind is glassy again. The energy is moderate (246). It’s a short window before the onshores return.

The Second Week & The Standout

The middle of next week is mostly messy with onshore winds and short-period slop.

Now, mark your calendar for Tuesday morning, 25th of August. This is the one to wait for. We’re looking at 2ft from the SE, but with a very long 16-second period again. The combined energy is solid (284). The wind is a clean cross-off from the SSW, so the wave faces will be clean and lined up. It’s a proper morning session, but be aware the crowd factor at Prainha can be a thing – sometimes it gets busy, so get there early.

Then, the real heavyweight pops up on Wednesday morning, 26th of August. The swell bumps up to 7ft from the SSE with a short 9-second period. This is a big pulse of power with energy hitting 1012 – that’s a serious amount of water moving. This is strictly for the experts; 7ft with that period will be a heavy, grinding wall. The wind is a light cross from the SSE, so it’s not going to be clean perfection, but the power is undeniable. This is an experts-only option.

The outlook finishes with Thursday (27th August) back to small glassy 2ft surf.

So, to sum it up: Thursday morning (13th August) for the glassy lines, and Tuesday morning (25th August) for the clean long-period swell are your best bets. The big 7ft pulse on the 26th is for the brave only.

Rusty.
