The Lowdown
Alright folks, Rusty here. Let’s break down what we’ve got coming up over the next couple of weeks.
This forecast is a real slow starter. The first week is pretty much a desert. The real action, if you can call it that, is buried in the second week. The standout window is around the 25th and 26th of August, and then again on the 27th, but even that comes with a major caveat.
Right now, through to the end of this week, it’s a total write-off. The swell is tiny, the periods are short, and the energy is weak. The combined energy for most of these days is under 100 (as low as 37), which is just a total lack of push. By Friday the 21st, we see a tiny bump in the afternoon with a 3ft east swell, but it’s still ordinary. The wind is cross-offshore though, so it’s clean, but you’ll be scratching for anything rideable.
Saturday the 22nd morning is interesting. We get a glassy start with a 3ft SSE swell and a better combined energy of 193 (moderate). The period is only 9 seconds, so it’s a bit soft, but if you’re desperate, paddle out at the crack of dawn. It goes onshore by the afternoon.
Sunday the 23rd is similar – glassy morning with a 3ft SSE swell, but the energy is only 100. It’s just not enough power to get excited about.
Now, here’s where it gets a little juicy. The real highlight is Monday the 25th morning. This is the best on offer. We’ve got a 3ft SSE groundswell rolling in with a long 14-second period and a combined energy of 416 (strong). The wind is glassy. That’s a clean, long-period swell. Because it’s a point break at Matinhos, that long period is actually a blessing – it’ll wrap in nicely and line up. The water is running about 69°, which is much warmer than normal for this time of year, so you’ll be comfortable.
Tuesday the 25th afternoon is also solid, with a 3ft SSE swell at 13 seconds and a cross-offshore breeze. Clean waves, but not as much juice as the morning.
Wednesday the 26th morning is the other standout. A tiny 2ft SE swell, but the period is a massive 19 seconds. That’s very long period groundswell. The combined energy is 430 (strong). This is a classic case where the size is small, but the energy is there. It’ll be glassy, so you’ll get long, clean lines. Don’t be fooled by the height – the power is real. This is a point break, so it’ll handle the long period beautifully.
Thursday the 27th morning is also worth a shout. A 3ft SE swell at 14 seconds, glassy, with a combined energy of 389 (strong). Another clean, solid session.
After that, the swell drops away fast. The 28th and 29th are back to small, weak, and poor. Then on the 1st of September, we get a jump in size – 7ft to 8ft – but it’s a short period easterly swell with strong onshore winds. The combined energy is high (over 1000 on the 2nd), but the conditions are poor. The wind will ruin it, and that size with a short period will be a messy close-out. That’s more for the kite surfers than anyone else.
To sum it up: the first week is a bust. The second week has a few clear windows of quality, clean surf. The best window is the 25th and 26th of August, with Thursday the 27th as a close second. After that, it’s sketchy again.
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.
