Matinhos Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.

The pattern starts off pretty quiet. Monday morning the 31st of August is glassy with a 2ft easterly swell, but it’s tiny and weak (83 combined energy). It’s surfable but nothing to write home about. The water is sitting at 70°, which is about 5° warmer than usual for this time of year – that’s notable, the ocean is unusually warm.

Tuesday the 1st of September shows a bit more life. The morning is glassy again, with a 4ft swell from ESE, period a short 7 seconds, so it’s a bit weak and crumbly. Still, the clean conditions make it worth a look for a longboard or a fun session. The afternoon gets choppy with a cross-onshore wind, so get out early.

Thursday the 3rd of September is the first real standout. The morning is clear, with a light cross-offshore NNW breeze. The swell holds at 4ft from the SE, but the period jumps to 11 seconds – that’s proper groundswell energy. The combined energy reads 272 (moderate) and the conditions are clean. Matinhos is a point break, and this longer period SE swell will set up nicely, drawing out the lines. It’s intermediate plus, very consistent, and you’ll have company – crowds are likely.

The following Friday morning the 4th is another glassy window, though the swell drops back to 2ft. It’s still got a nice 11-second period, so the energy is there (208 combined), just small. Fine for a cruise.

After that, we hit a rough patch. From the 5th through to the 10th, it’s a mix of poor-to-marginal conditions. Gusty winds, choppy seas, and a lot of short period junk. The swell bumps up on the 9th and 10th, with a 8ft easterly on Wednesday afternoon (1340 combined energy – strong!) and a 8ft easterly on Thursday afternoon (1634 combined energy – very strong). But both times the wind is a messy cross-shore, and the period is short (8-10 seconds). That’s a lot of power with no shape – looks more interesting for kite surfing than paddle surfing.

The next real highlight comes on Friday the 11th of September. Morning is clear, glassy, with a 5ft E swell at a 10-second period. Combined energy of 361 (moderate). Clean waves, no wind. That’s a solid session for intermediates. Afternoon gets a bit onshore, so aim for the early.

Saturday the 12th of September morning is also glassy, with a 3ft ESE swell. It’s small but clean, perfect for a relaxed paddle.

Heads up: Tuesday the 15th of September morning shows another small clean window – 4ft easterly swell, cross-offshore wind. It’s ordinary but rideable.

Overall, the best bet is Thursday the 3rd of September morning. Glassy conditions with a proper 11-second groundswell, clean lines at Matinhos point. Friday the 11th of September morning is the other standout – a bit bigger, also glassy. Everything else is either small, or blown out, or too lumpy.
