The Lowdown
Alright folks, Rusty here. Let’s get into it for the next couple of weeks at Matinhos. Clean conditions are the name of the game early on, so you’ll want to be sharp for those windows, because there are big gaps of nothing special in between.
The first real chance to get wet is Wednesday morning, the 12th. It’s not massive, but the wave energy is moderate (342), with a 4ft swell coming from the SSE, and the combo of a 12-second period and glassy wind is a beauty. That’s a solid point-break morning – clean, lined-up, and all yours if you’re an intermediate.
Friday morning, the 14th is another glassy morning, though the swell has dropped to 2ft from the SE with moderate energy (211). It’s a little weak but super clean.
The standout of the whole run? It’s Saturday morning, the 15th. Offshore wind from the NNW, 3ft of SSE swell with a 12-second period, moderate energy (265), and clean conditions. That’s the session to circle on your calendar – proper shape, no chop, and the point will be running nicely.
Sunday morning, the 16th offers glass again, but it’s only 3ft of short-period (8s) SE swell with weak energy (120). You could get a few soft ones if you’re desperate.
We then hit a rough patch from the 17th through the 24th. There’s barely anything rideable – mostly poor conditions, onshore wind, weak swell, or straight-up choppy. A few mornings have clean-ish wind, but the swell is tiny (1ft to 2ft) and the energy is low (47 to 178). This stretch looks more like a kite-surfing setup if you’re into that, but for a paddle surfer, it’s basically a write-off.
Then, way out in the forecast for Tuesday morning, the 25th of August, there’s a promising one. A glassy calm morning with a 2ft groundswell from the SE and a very long 15-second period. The energy is moderate (334) and the conditions will be glassy – that’s a real point-break treat, but it’s two weeks away, so keep your fingers crossed it holds.
And the Wednesday morning, the 26th has a bigger 6ft swell from the SE, but with a short 7-second period and weak-to-moderate energy (490). The glassy wind will make it look good, but that short period will be a bit lumpy on the face – okay for experienced surfers who can work with it.
Stay sharp, keep an eye on the wind shifts, and don’t waste the good windows.
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.
