Matinhos Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it for Matinhos. We’ve got a bit of a slow cooker of a forecast, with a real standout window that’s worth holding out for.

The overall pattern is a bit of a mixed bag. We start with small, disorganised E swell at 3 ft, and the early part of the outlook is pretty ordinary. The good news is, the wind is often glassy or light, especially on the Sunday morning, but the wave energy is weak (111). The water is a touch warmer than normal at 69°, which is a nice little bonus for this time of year.

The first real flash of hope comes on Tuesday, September 1st. The morning sees a clean, cross-off wind with a 3 ft ESE swell, and the energy picks up a notch (117). But the real beauty is the Tuesday afternoon session: glassy conditions with a 4 ft SE swell, energy at 146. That’s the kind of clean, fun-sized wave you can surf all afternoon without a crowd. It’s a great little session for the intermediate surfer.

The swell builds through the week, but the wind gets messy. On Wednesday, September 2nd, the swell pushes 5 ft (energy 333), but it’s cross-on and windy. That’s more of a kite-surfing setup than a clean paddle session. The following Thursday morning, September 3rd, is a different story: clean cross-off wind, a 4 ft SE swell with a nice 10-second period, and solid energy (242). That’s another good window.

After a few more days of messy cross-onshore wind and building swell, we hit the real standout. Monday, September 14th, is the one to circle on the calendar. The morning wave is 6 ft from the SE, with a long 9-second period and energy blowing up to 539. The wind is light cross-shore, keeping things fairly clean. The afternoon is even bigger: 7 ft from the ESE, with a massive energy reading of 1405. The wind is onshore, but it’s light. This is big, powerful groundswell. For Matinhos, a point break, that long period and solid size will produce some excellent, lined-up waves. It’s definitely expert territory at 7 ft, but for the experienced crew, this is the best on offer in the whole 16-day window. The Friday morning, September 11th, with glassy conditions and a 3 ft SSE swell (216 energy) is a solid, smaller option too.

The last couple of days of the forecast look a bit tricky again, with cross-onshore wind and moderate energy. So, to sum it up: the early week is small and fun, the middle is a battle with the wind, but the second week, specifically Monday the 14th, is the big, powerful, and promising standout. Get your big-wave board ready.

Rusty.
