The Lowdown
Alright folks, Rusty here. Let’s get into what’s on the menu for Matinhos.
The next 16 days start off a bit rough. We’ve got a decent swell arriving, but the wind is a pain. Sunday the 9th and Monday the 10th are a write-off with onshore and cross-onshore winds messing up the waves. It’s not until Tuesday the 11th that things start to look a little better, but even then it’s a bit marginal.
The real standout of the forecast period is going to be Wednesday the 12th afternoon. The wind goes glassy, and we’ve got a 4ft swell from the SE with a period of 12 seconds. It’s not a monster, but the energy is moderate (340) and the conditions are clean. With the wind glassy, the waves will be smooth and fun, perfect for an intermediate surfer. The water is a warm 70°, which is much warmer than usual for this time of year, so you’ll be in for a treat.
Thursday the 13th morning is also a gem with calm winds and a glassy surface, but the swell drops to 2ft from the SE, so it’s a smaller option. The best wave on offer is still Wednesday afternoon.
If you can wait, Friday the 21st of August is a big one. The morning shows a solid 7ft swell from the SSE with a 9-second period, and glassy wind. The combined energy jumps to 659, which is a strong pulse. This is for the more experienced surfers, as anything over 5ft can get a bit much for beginners. The waves will have some punch, and with zero wind, the lineup will be clean. It’s a long-range call, so it’s promising but not locked in yet.
The rest of the second week is a mix of small to moderate swells, with some clean windows on the 22nd and 24th, but nothing that beats that 21st morning.
Overall, for the best surf, aim for Wednesday the 12th afternoon for the fun, clean waves, or book your schedule for Friday the 21st morning for the bigger, more powerful stuff.
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.
