Prainha Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what we’ve got coming down the line for this stretch of coast.

Alright, let’s be honest right off the bat: the first week is a grind. We’re starting on Monday the 31st of August, and while there is small wave energy around, it’s nothing to write home about. The first few days are made up of little ankle-to-knee high dribblers, mostly from the east, with periods that are on the shorter side. It’s going to be a slow start.

We do get a bit of a pulse building into Wednesday the 3rd of September, and that morning is the first real standout. Prainha sees a clean, glassy start to the day with that wind going calm. The swell is 3 ft from the ESE, but the period bumps up to 11 seconds – so you get a bit more push and shape to the waves. It’s a moderate wave energy session (combined energy of 224), and the water temperature is sitting at 69°, which is a touch warmer than normal for this time of year. For the advanced surfer needing a fix, that Thursday morning window is the best on offer for the first week.

Things then go pretty average again until we hit a promising window around the 10th of September – that’s a Thursday again. The morning of the 10th flips the script. Swell picks up to 5 ft from the east, period at 8 seconds, and the wind is glassy with a "W" breeze. The combined energy jumps to 248 – moderate energy but very surfable. That is another cracker of a morning session.

After that, the swell size really starts to muscle up. On Thursday afternoon the 10th, the swell jumps to 7 ft from the east (combined energy of 941) – but the wind gets ugly, pushing cross-onshore and blowing it out. That one is for experts only, and even then, only if you’re willing to battle the chop.

The standout of the whole outlook? It has to be Monday the 14th of September. Early morning glass: zero wind, the water is like a mirror. Swell is a clean 3 ft from the SE, period at 11 seconds, and the combined energy is the highest we see – 268. The waves will have proper shape and the clean conditions make it the pick of the entire run. That is the session to book in for.

After that, we move into Tuesday the 15th with some longer period groundswell (12 seconds) from the SE and swell around 4 ft to 4 ft, but wind is light cross-shore, so it’s still rideable. The energy stays solid (336 in the morning). It just won’t be as flawless as the day before.

Overall, there’s surf spread across the fortnight, but the real gems are that Thursday morning the 10th and the Monday the 14th glass-off. The first few days are a fade, but don’t write off the second week – it brings the goods.

Stay frothing,
Rusty
