Prainha Surf Forecast and Surf Report

Alright, this is Rusty, and I’m looking at the next couple weeks at Prainha. The water temp is sittin' around 65°, which is just a touch cooler than average for early July – nothin’ wild, just the ocean feeling a bit more winter than usual.

Honestly, mate, the outlook is pretty flat for ages. For the first week and a half, we've got tiny, weak swell and a whole lotta "meh." The wave energy is mostly in the doldrums, readings like 175 (moderate) and then dropping off to barely 60s and 30s (weak). It’s frustrating – there’s surfable little lines, but the conditions are ordinary. A few windows pop up, like Saturday the 4th morning with glassy wind and a 2ft swell from the SE, but it’s so small. Sunday the 5th morning, we get a touch of offshore wind from the W, which would clean up that 2ft SE groundswell (period 12 seconds), but it’s still marginal.

There are a few sessions worth a look if you’re desperate. Wednesday the 8th morning, glassy again with a 2ft SE swell, but the period drops to 10 seconds – not much grunt. Thursday the 9th and Friday the 10th (mornings) have glassy or cross-off winds, but those swells are tiny. This stretch is a grind.

Now, hang on. The real buzz starts over a week out. On Friday the 17th of July, we see the energy jump up significantly, with 328 (strong) showing on the combined swell energy, but the wind is howling from the SSE at 19 mph, and the comments are poor. Not the day.

Saturday the 18th of July morning is the standout for the whole period. We’re looking at a 2ft swell from the SSE with a very long period of 16 seconds – that's proper groundswell. The combined energy is a solid 304 (strong). But the clincher: glassy wind from the W. Clean. Smooth. For a break that gets a 3/5 rating for advanced surfers and is "very consistent," this is a quality window. That long period will wrap around the point better than the beach, but it’ll bring groomed, glassy runners. Crowds are "sometimes" a thing here, so it’s not gonna be empty, but with that glass, it’s a target.

Then on Sunday the 19th of July morning, there’s another pulse: 5ft from the E, but a short period of 8 seconds, so it’s windswell. Combined energy is 258 (moderate). Wind is SW cross-off at 9 mph – not perfect, but it’s rideable. That 5ft size is getting into the “not for beginners” zone for a bit more fun.

So to sum it up: the next 12 days are a waiting game with small, ordinary waves. The one true standout to mark on your calendar is Saturday morning, July 18th at Prainha – glassy, clean, and that long-period groundswell. It ain’t huge, but it’ll be quality. Sunday the 19th morning is the runner-up with more size, but less quality.
