The Lowdown
Alright, mate, Rusty here. Let’s get into it.
We’re looking at a pretty slow spell for Matinhos. The forecast is dominated by small, weak swell and a lot of onshore wind, so you’ll be waiting a while for anything decent. The water temperature is sitting at 69°F, which is much warmer than normal for this time of year.
For the first week, from Wednesday the 19th to the 23rd, it’s pretty grim. Swell is tiny, mostly under 3 ft, and the wind is all over the place – mostly cross-onshore, which is going to mess up the surface. The combined swell energy is low, in the range of 33 to 316, so there’s just not much power in the water. There’s a window on Friday morning, the 21st, with a light cross-offshore wind from the WSW, but the swell is only 3 ft from the S with a short period of 5 seconds, so it’s not going to be anything special.
The real standout, the one you’ve been waiting for, arrives on Monday afternoon, the 24th of August. The swell pumps up to 5 ft from the SSE, with a very long period of 16 seconds. That’s proper groundswell. The combined energy jumps to 1364, which is strong. The wind is glassy, and the conditions are described as excellent for experienced surfers. This is the pick of the forecast. The only caveat is that a long-period swell like this can break a bit straight at beach breaks, but at Matinhos, a point break, it’ll be lining up nicely. Crowds are often here, so expect company.
After that, the following days are a mixed bag. Tuesday morning the 25th has a clean 3 ft from the SSE with a 14-second period, but the energy is lower at 403. After that, it’s back to small, weak, and often onshore through the rest of the week and into September. There’s a moment on Saturday morning the 29th with a 5 ft S swell and glassy conditions, but the period is a short 6 seconds, so it’ll be a bit choppy and weak.
The long-range window from the 24th is the standout. If you’re an experienced surfer, that’s your window. Beginners might find the 5 ft swell a bit much, but the 3 ft on the 25th could be manageable.

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.
