The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for the Matinhos stretch.
We've got the first real surfable window kickin' off on the morning of Thursday, the 13th. It's not gonna be a monster, but it'll be a damn sight better than flat. The combo swell energy is respectable, sitting at 422 (moderate), with a clean 3ft groundswell rolling in from the SSE. That 15-second period is a good sign for shape. And the wind? Glassy. No, really, glassy – a 3 mph southerly and "glass" in the notes. That makes for a sweet, clean start to the day.
The standout in this whole run is the morning of the 13th at Matinhos. It's a point break, very consistent, and it loves a south swell. You get that 3ft, 15-second SSE groundswell with absolutely no wind to chop it up. The water temp? No big anomaly flagged, so it's about what you'd expect for this time of year.
The rest of that first week has some moments. Friday the 14th offers a bit of a repeat with a glassy morning and a 2ft to 3ft SE swell, but the real gem is that Thursday morning. Saturday and Sunday look ordinary with short-period, onshore wind slop. By the 17th, Monday morning, we get a cleanskin again: 4.6ft from the ESE with a 9-second period and dead calm winds. That's a solid intermediate wave, though the period is a bit short for a point break to really line up perfectly.
Then it goes a bit quiet. There's a stretch from mid-week where the wind turns naughty, and the swell drops off. We get a little pulse on the 23rd, Sunday afternoon, with a glassy 4.3ft SSE swell and a 9-second period – that's worth a paddle. And then again on Tuesday the 25th morning, a sneaky 2.3ft SSE swell shows up, but the period stretches to 11 seconds, and it's glassy. That's a good, clean, if small, day.
After that it's mostly small, ordinary surf until the end of the run. The biggest call is for the morning of the 13th. That's the one you don't miss.

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.
