Prainha Surf Forecast and Surf Report

Alright, Rusty here. Let’s break down what’s brewing for Prainha over the next couple weeks. The water’s running about 68°, which is a degree warmer than average for this time—so it’s a bit of a bonus.

Thursday morning the 27th starts off with a clean 3 ft swell out of the southeast, light crosswind, and glassy water. The combined energy is moderate at 293, with a long 14-second period. That’ll bring some push, but at a beach break, that long period can make it a bit closeout. It’s marginal, not a standout.

Friday morning the 28th is a bit better. Glassy conditions with a light offshore breeze from the southwest, and 3 ft from the east. The period is short at 7 seconds, so it’s a wind swell—more frequent but less grunt. Energy is moderate at 157. Surfable and clean, but ordinary.

Saturday morning the 29th is similar: glassy, 4 ft from the east, short period of 8 seconds, moderate energy at 142. Clean, but nothing special.

The pattern holds through the start of the next week. Monday morning the 31st has 3 ft from the east, light offshore wind, 9-second period, moderate energy at 130. Clean. Tuesday morning the 1st of September is the same deal, 3 ft, clean, but small.

The real standout appears in the second week. Thursday morning the 10th of September shows a jump: 5 ft from the south-southeast, 6-second period, with a light offshore from the west-southwest. The combined energy hits 294—moderate to strong—and the report says “expect good surf conditions.” This is the best window of the whole outlook. That size is good for advanced surfers, but will be a handful for beginners. The direction is off the SSE, not the ideal S, but it’ll work.

Then Friday morning the 11th of September is the other highlight: 5 ft from the east-southeast, glassy, light wind from the west. Energy is moderate at 274, and again “expect good surf conditions.” That morning will be clean, with a bit more shape. The period is short at 6 seconds, so it’ll be a little crumbly, but glassy offshore is a huge plus for clean faces. That’s the morning to aim for, if you can handle it.

Crowds at Prainha are sometimes an issue, so don’t expect solitude.

First week is small and average, with a few clean windows. Second week brings the real action, especially Thursday and Friday mornings. After that, the wind turns and the swell drops.
