Matinhos Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s going on in the water at Matinhos over the next couple of weeks.

Right off the bat, we’ve got a bit of a slow start, but the first real window of clean surf shows up on the morning of Thursday, the 3rd. The water is running at 70°F, which is a solid 4°F warmer than usual for this time of year – that’s a proper gift, makes the early sessions a lot more inviting.

Thursday, September 3rd morning is the standout for the whole outlook. It’s not big, but it’s beautiful. We’re looking at a 4ft SE groundswell with a solid 11-second period, sliding into Matinhos. The combined energy is a solid mid-range 367, so there’s some push behind it. But the real kicker is the wind – a light 3 mph northerly, which is cross-offshore. That’s going to keep the faces clean and lined up. Expect some proper, well-shaped waves rolling through the point. This is the session to circle. The water is warm, the wind is sweet, and the swell is consistent. Perfect for the intermediate-plus crew.

The afternoon of the 3rd sees the wind swing easterly at 6 mph, bringing a bit of cross-on chop. The swell drops slightly to 4ft, and the energy eases to 273. It’s still surfable, but the morning was the magic hour.

Friday the 4th is a write-off. The wind picks up from the south at 9 mph, cross-on and bumpy, dropping the swell to 2ft. The energy drops to 159. It’s messy.

Saturday the 5th is more of the same – south wind, cross-on, small 2ft E swell. The period is short, only 8 seconds, so the waves will be weak and lumpy. Not worth the paddle.

Sunday the 6th is a cross-shore wind with a short-period SSE swell at 4ft, but the period is a tiny 6 seconds. The energy is low (137). It’s going to be a bumpy, short-interval mess.

Monday the 7th starts to look a little more interesting, but it’s marginal. The morning swell hits 5ft from the SSE with an 8-second period, pushing energy up to 317. That’s a decent amount of water moving, but with a 9 mph cross-shore wind, it’ll be a bit of a wrestling match. Not clean, but there’s some size for the keen.

Tuesday the 8th is a bit of a tease. The swell drops to 3ft but the period stretches back to 11 seconds from the SSE. The energy is still a moderate 277. The morning has a light cross-shore, but the afternoon turns glassy and onshore with a 3 mph wind. That glassy afternoon could offer some clean little lines if you’re on a log.

Wednesday the 9th is another solid morning. The swell is 5ft from the east, with a short 7-second period, but the energy is 265. The wind? Dead flat, glassy, from the north at 3 mph. That’s a morning for the early bird. The waves will be a little crumbly with that short period, but perfectly clean.

Thursday the 10th morning is similar to the 3rd – 4ft east swell, 8-second period, but with a light 6 mph north cross-offshore wind. Clean waves, energy at 240. Good morning.

Friday the 11th morning is another glassy dawn patrol with a 4ft east swell, 9-second period, and a 3 mph north-west wind. The energy is 212. It’s a smaller version of the 9th, but still a clean start to the day.

After that, it gets patchy. The 12th has a clean afternoon with a 3ft east swell, but the 13th and 14th are blown out by south winds. The swell holds around 3ft to 3ft, but it’s choppy and cross-on.

The rest of the week into the 18th is small, weak, and mostly messy. The swell drops to 2ft or 1.0ft with energy falling to 21 on the 17th afternoon. There’s simply nothing worth chasing in the second week. The best bet is to nail those first few days of September.

So, to wrap it up: Thursday morning, September 3rd is the clear winner. It’s the cleanest, most consistent, and most enjoyable session in the whole 16-day window. The water is warm, the wind is perfect, and the point is going to be working. The Wednesday 9th and Thursday 10th mornings are your back-up plans for a clean, smaller wave.

Stay stoked, and I’ll see you out there.
