Matinhos Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into this forecast for Matinhos.

First up, the water temp is sitting at 69°, which is about 5° warmer than usual for this time of year. That’s a notable little bonus, making it feel a treat.

Right now, we’re looking at a quiet start. The early part of the week is pretty flat and messy with onshore breezes and weak swell. It's a waiting game. The first real window of opportunity opens up on the morning of Saturday, the 22nd. We've got a building SSE swell pushing 4ft and the wind goes glassy - dead calm. The combined swell energy hits 269 (moderate), so there’s some push there. It’s only a short period at 10 seconds, but with clean, glassy conditions, that morning at Matinhos point looks like the first decent chance to get wet. The afternoon sees the wind shift cross-onshore and chop things up, so Saturday morning is the clear early standout.

The most promising swell of the whole run shows up on Monday, the 24th. We’re looking at a solid 5ft swell from the SE, with a long period of 14 seconds pushing through. The combined energy is reading 847 (strong). That’s proper groundswell energy. The catch is the light rain and onshore wind, which makes it a “questionable tide” session. If you can work the tide right, there’ll be some powerful lines, but you’ll be dealing with a bit of bump on the face.

Tuesday the 25th then offers a real gem. The swell drops back to 3ft, but it’s still from the SSE with a juicy 13-second period. The combined energy is still a healthy 304. The kicker? A dead calm, glassy morning. That’s about as clean as it gets. For a point break like Matinhos, a clean, long-period SSE swell lining up perfectly from the S optimum direction is about as good as it looks on paper. If you can get out Tuesday morning, that's likely your best session of the outlook. The afternoon holds glassy conditions too with a light breeze.

After that, things get a bit more ordinary with smaller wave heights and some cross-onshore winds creeping back in during the final days of August. There’s a gap in quality surf, but right at the very end of the run, on Monday the 31st of August, we see another pulse. The morning has a 5ft easterly swell with clean, cross-off winds. That combined energy gets up to 294 again, so another solid option to finish the period.

One to watch: The Monday the 31st morning session with that 5ft E swell and clean cross-off wind looks like a solid end-of-run option.

Crowds at Matinhos can get busy, and you can bet the locals will be out for those clean glassy mornings. It’s a very consistent spot, so it tends to hold up better than most.

Rusty.
