The Lowdown
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.

Information about the Matinhos Surf forecast
The above surf forecast table for Matinhos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Matinhos can be found by selecting the local surf guide option on the grey menu. Our Matinhos surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Matinhos) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Matinhos may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Matinhos is 15 km (9 miles) from Paranagua. If you plan a holiday in Paraná, look for hotels and other accommodation in Paranagua. Paranagua has rooms for a wide range of budgets as well as car hire and transport links.
