Prainha Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming our way for the next couple of weeks.

Right off the bat, it’s going to be a tough slog. For the first week and a half, we’ve got swell on the cards, but the conditions are just plain ugly more often than not. The water’s sitting at a touch warmer than normal for this time of year, about 69°F, but that’s the only easy thing about this stretch.

We kick things off at Prainha. This is an advanced break, very consistent, and exposed to swell from the south, so it grabs plenty of energy. On Saturday the 29th, we’re seeing a mix of small east swell around 4 ft with a short period of only 8 seconds. The combined swell energy is a moderate 146, but the wind is a cross-off southerly at 12 mph and the surf is poor. It’s not worth paddling out.

Sunday the 30th and Monday the 1st are tiny, with waves dropping to 2 ft to 3 ft. The energy drops into the double digits (71 to 94), which is weak. Monday afternoon, the wind goes glassy with zero wind, and the energy jumps to 144, but it’s still just small, ordinary surf. You could get a few but it’s nothing to get excited about.

Tuesday the 1st of September morning sees a bit of a change – a light 6 mph west wind turning offshore and a small 2 ft swell from the southeast. The period is still short at 8 seconds, and the energy is moderate at 121. It’s surfable, but ordinary. That pattern of small, ordinary surf drags on with variable winds through the 2nd and 3rd. Wednesday the 2nd afternoon brings a 3 ft southeast swell with period stretching to 10 seconds and energy hitting 204, a solid boost in power, but the wind is a light cross-onshore, which hurts the surface.

Thursday the 3rd morning looks interesting. It’s glassy with a 3 ft southeast swell, period of 9 seconds, and energy of 176. Clean conditions. If you’re itching, that might be your moment. The glassy conditions continue into Friday the 4th morning with a 3 ft east-southeast swell and a 10-second period, energy of 156. Still small but clean.

From there, we hit a real lull. Saturday the 5th and Sunday the 6th offer tiny waves with poor quality. The 6th has fresh 19 mph southwesterlies making it look more like a kite day than a surf day.

The first real standout comes on Thursday the 10th of September. The morning is glassy with the wind calm from the north. We get a 4 ft east swell with a 9-second period and the combined energy is a solid 241. The report says "expect good surf conditions." This is the pick of the whole forecast – clean lines, enough size and push for the advanced crowd at Prainha. It’s not huge, but it’s the most promising window by far.

After that, the surf fades back to small and ordinary for the rest of the run into the second week. Saturday the 12th afternoon brings another glassy window with a 3 ft east-southeast swell and energy of 203, which could give a few fun ones if you’re local.

Overall, if you’re surfing Prainha, you’ve got a long wait. Thursday the 10th is your best bet – clean, glassy, with moderate energy. The rest is a patience game. Don’t hold your breath for the long-range stuff; it stays small and inconsistent.

Rusty.
