Prainha Surf Forecast and Surf Report

Alright, let’s talk about Prainha. This is an advanced wave, super consistent, and it loves a southerly swell to really get going. Water temp is about 68°F, which is a touch warmer than normal for this time of year – not a big deal, but a nice little bonus if you’re in a spring suit.

This forecast has a slow start, with nothing worth paddling out for until Monday the 24th. The weekend is a total write-off, so don’t even think about it on Sunday the 23rd. Just wait it out.

Monday the 24th morning is our first decent look. We’ve got a clean 3ft SE swell, period of 14 seconds, with a light cross-off breeze. Combined energy is at 258 (moderate) – nothing huge, but it’s clean, and for an advanced spot like Prainha, that’s going to be fun. The afternoon has more energy (327) and a longer period (15 seconds), but the wind goes a little cross-onshore, so it won’t be as perfect.

Tuesday the 25th is a bit of a mixed bag. The morning is glassy with a 2ft SE swell, period of 13 seconds, but the energy is weak (141) and the conditions are just ordinary. The afternoon is the same story (106 energy). Surfable, but not a standout.

Now, Wednesday the 26th is where we get the best of the early run. Morning has a 3ft SE swell from the south-east, period of 16 seconds (that’s a nice long groundswell), and clean offshore wind (SW 6 mph). The energy jumps up to 339 – that’s solid. The afternoon is even stronger, with 3ft and 410 energy, but the wind is cross-offshore. Still good.

Thursday the 27th carries on the clean theme. Morning has 3ft SE swell, 14-second period, with clean conditions and 316 energy. Afternoon is similar with 2ft and 219 energy. Both are good, solid surfing days for the experienced crew.

Then we hit a real rough patch. From Friday the 28th all the way through to Sunday the 7th of September, it’s mostly poor conditions. There are a few moments where the wind is clean, like Thursday the 2nd of September morning (glassy, 3ft SE, 12-second period, 231 energy) – that’s a hidden gem if you can wait that long. But overall, this period is plagued by short-period windswell (6 to 8 seconds), onshore winds, and choppy surf. The energy values spike up to 1043 on Wednesday the 2nd afternoon, but that’s a 6ft SSE swell with cross-onshore wind and a period of just 11 seconds – that’s going to be a bumpy, messy mess, likely more interesting for a kite surfer than a paddle surfer. Over 5ft, it’s already getting too big for beginners, and with that wind, it’s only for experts who like a challenge.

The real standout in the whole 16-day window is hands down Wednesday the 26th morning. You’ve got a clean 3ft SE groundswell (16-second period), offshore wind, and solid 339 energy. It’s not a huge swell, but at Prainha, with that long period and clean conditions, it’s going to line up beautifully. The second best is Thursday the 27th morning. Both are in the early part of the forecast, so they’re more reliable. The long-range look (September 2nd morning) is promising but less certain – glassy, small, but it could be a fun little session if the weather plays ball.

Don’t forget, Prainha can get crowded sometimes, so get in early for that Wednesday morning session.

The gap from Friday the 28th to Sunday the 7th is about 11 days of mostly poor to marginal surf. That’s a long stretch. This area can be fickle, but it tends not to stay poor forever – forecasts can change.

Rusty.
