Matinhos Surf Forecast and Surf Report

Alright, Rusty here, let's look at what's on the table for the coming weeks.

Honestly, right now it's pretty flat. We’re looking at a big gap of surf that just isn't worth paddling out for. The first week and a half or so at Matinhos is a write-off. We've got tiny, weak swell from the east with periods around 7 to 8 seconds, and the wind is all over the place – mostly cross-onshore or just messy. The water is a touch warmer than normal for this time of year, sitting at 68°F, but that's about the only positive.

The first real sign of life shows up on the morning of Wednesday, August 5th. It's still small, with a 2ft swell from the SSE, but the period jumps to 11 seconds and the energy is moderate (119). The wind is glassy calm, which is a major positive. The conditions are still described as "very ordinary," but it's the first hint of something better. The afternoon turns onshore again, so that morning window is the only shot.

We then hit another dry spell until Monday, August 10th. The swell starts to build on the Monday morning, hitting 5ft from the SSE, but the wind is a strong onshore of 12 mph from the SE, making it a complete mess. The energy is ramping up though (328), and by Monday afternoon it's 6ft from the SSE with a moderate energy of 404. The wind is still cross-onshore, so it's going to be choppy and pretty ugly.

The best bet in the whole 16-day window looks like Tuesday, August 11th and Wednesday, August 12th. On Tuesday morning, we have a 5ft swell from the SSE, a period of 10 seconds, and a strong wave energy of 553. The wind is a light cross-shore from the SW, which is better than onshore. The forecast calls it "marginal," but it's the best we've got. The afternoon cleans up a bit more with a 5ft swell and a 13-second period, giving a strong energy of 746. The wind is still light and cross-shore. Wednesday the 12th morning is similar, with a 4ft swell from the SSE and a 14-second period, but the energy is still strong (574). The afternoon sees the energy spike to a massive 1094 with a 5ft swell from the SSE and a 13-second period. Winds are light and cross-shore. These are the standout days.

However, keep in mind that long-period swell (over 11 seconds) at a point break like Matinhos can be a good thing. It should bring some nice, lined-up waves, but the sets will be more spread out, so you'll have to be patient. The swell direction is from the SSE, which is close to the optimum S direction for this spot. It's a point break, so it should handle the long period better than a beach break.

After that, the surf drops off again. By Friday, August 14th, the swell is fading and the wind gets messy with light rain. The energy is still moderate (547 on Friday morning), but the conditions are poor. The rest of the run into August 17th is just small, weak, and mostly onshore. The morning of Monday, August 17th has a 4ft swell from the ESE with a short 8-second period, and it's glassy, but it's only a 1 out of 10. It's just not enough.

So, to wrap it up: don't waste your time for the first 9 days. The real window is Tuesday, August 11th and Wednesday, August 12th. That's where the size and the energy are, and the wind is manageable. The rest is a waiting game.

Rusty.
