The Lowdown
Alright, Rusty here again. Let’s break down the Matinhos forecast for the next couple of weeks, in feet and knots.
The first few days are a bit of a dud. Not much to get excited about, just small, weak waves. The water is warm, 69°, which is about 4° warmer than usual – feels like a hot tub out there.
The real show starts on Saturday, August 22nd. The morning is looking mint with 3-4ft swell from the SSE, and the ocean is flat calm – glassy as can be. The energy is moderate (270), and the period is 10 seconds, so the waves will have some push. The wind messes it up by afternoon, so get out early.
Sunday, August 23rd, is another good one. Morning glass again with 3-4ft SSE swell, 9-second period, and solid energy (207). Expect other folks in the water as it’s often crowded, but the conditions are about as good as it gets for the first week.
Now, the big one: Monday, August 24th, in the afternoon. Swell jumps to 4-5ft from the SE, with a really long 14-second period. This is groundswell, carrying some serious punch. The energy is strong (861), and the wind goes glassy. This is the session you’ve been waiting for. That long period will make the waves clean and powerful, absolutely perfect for this point break.
Tuesday the 25th morning is still decent, with 3-4ft from the SSE and glass, but the energy is lower (359). Wednesday the 26th morning has 4-5ft from the NE, but it’s a short-period windswell (6 seconds), so it’ll be a bit soft.
The second week gets a bit blown out. August 31st morning sees a big 7ft swell from the SSE, but the wind is cross-on and the energy is massive (1164). That’s a lot of power, but with messy conditions. Only for the experts.
If you’re picking one session, lock in the afternoon of Monday, August 24th. The Saturday the 22nd and Sunday the 23rd mornings are nearly as good, just a bit smaller. Don’t miss it.
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.
