The Lowdown
Alright folks, Rusty here. Let’s get into this forecast for Matinhos.
First up, the water temp is sitting at 69°, which is about 5° warmer than usual for this time of year. That’s a notable little bonus, making it feel a treat.
Right now, we’re looking at a quiet start. The early part of the week is pretty flat and messy with onshore breezes and weak swell. It's a waiting game. The first real window of opportunity opens up on the morning of Saturday, the 22nd. We've got a building SSE swell pushing 4ft and the wind goes glassy - dead calm. The combined swell energy hits 269 (moderate), so there’s some push there. It’s only a short period at 10 seconds, but with clean, glassy conditions, that morning at Matinhos point looks like the first decent chance to get wet. The afternoon sees the wind shift cross-onshore and chop things up, so Saturday morning is the clear early standout.
The most promising swell of the whole run shows up on Monday, the 24th. We’re looking at a solid 5ft swell from the SE, with a long period of 14 seconds pushing through. The combined energy is reading 847 (strong). That’s proper groundswell energy. The catch is the light rain and onshore wind, which makes it a “questionable tide” session. If you can work the tide right, there’ll be some powerful lines, but you’ll be dealing with a bit of bump on the face.
Tuesday the 25th then offers a real gem. The swell drops back to 3ft, but it’s still from the SSE with a juicy 13-second period. The combined energy is still a healthy 304. The kicker? A dead calm, glassy morning. That’s about as clean as it gets. For a point break like Matinhos, a clean, long-period SSE swell lining up perfectly from the S optimum direction is about as good as it looks on paper. If you can get out Tuesday morning, that's likely your best session of the outlook. The afternoon holds glassy conditions too with a light breeze.
After that, things get a bit more ordinary with smaller wave heights and some cross-onshore winds creeping back in during the final days of August. There’s a gap in quality surf, but right at the very end of the run, on Monday the 31st of August, we see another pulse. The morning has a 5ft easterly swell with clean, cross-off winds. That combined energy gets up to 294 again, so another solid option to finish the period.
One to watch: The Monday the 31st morning session with that 5ft E swell and clean cross-off wind looks like a solid end-of-run option.
Crowds at Matinhos can get busy, and you can bet the locals will be out for those clean glassy mornings. It’s a very consistent spot, so it tends to hold up better than most.
Rusty.

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.
