The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for Matinhos over the next couple of weeks.
Alright folks, for the Matinhos area, we're looking at a pretty slow start. The water is a beautiful 71°F, which is much warmer than usual for this time of year – a real treat if you can get in. But the waves? Nothing to write home about for a while. We've got a bit of a dry spell from now until the weekend of the 22nd and 23rd, with mostly tiny, weak swells and messy wind. The wave energy is feeble (52 on Thursday morning, dropping to 31 by Friday afternoon), so the board's staying dry unless you just want a float.
The first real flicker of hope comes on Saturday the 22nd. A little pulse from the SSE rolls in, around 4ft, with a moderate 10-second period. The energy picks up a bit (318), but the onshore wind from the ESE is gonna mess with it, making it messy. It’s a marginal call at best. Sunday the 23rd doesn't look much better, with the winds staying on it.
Now, keep your eyes on Monday the 24th and Tuesday the 25th. This is where it gets interesting. Monday the 24th afternoon sees a proper groundswell from the SE, building to 5ft with a long 16-second period. The energy jumps to 1054 – solid, moderate to strong stuff. The wind is a bit of a cross-on shore from the south, so it'll have some texture, but that's the price of a bigger, longer-period swell. Then Tuesday the 25th morning is where the magic might happen. The swell drops a little to 3ft from the SSE, but that 14-second period is still juicy, with 413 in energy. And best of all, the wind goes glassy from the SW. Matinhos itself will be clean and organized, with those long lines wrapping in. It's a smaller day, but the quality will be miles better than anything else we've seen. That Tuesday morning is the standout for a clean, fun session.
The good conditions stretch into Wednesday the 26th and Thursday the 27th mornings with glassy winds and clean 3ft swell, though the swell direction shifts a bit to the SE. These are solid, reliable mornings for a longboard or a funboard.
Then we hit a bit of a lull again towards the end of the month and into the start of September. Lots of onshore wind and messy, weak surf. The energy drops right back down below 200 most days. The wind is from the south and southeast, just chopping everything up.
Hold onto your hats for the very end of the forecast period, on Friday the 4th of September. This is a long-range call, but it looks promising. We’ve got a bigger pulse coming in from the SSE, hitting 8ft with a 10-second period and over 1000 in energy. The wind is off-shore from the west, cleaning it right up. Now, 8ft is expert territory. This is not for the faint-hearted. It’s going to be a powerful, hollow day at Matinhos for the experienced crew only. For the rest of us, it's a spectator sport.
So, to sum it up: grab the Tuesday the 25th morning for the cleanest, most user-friendly session. Circle Friday the 4th of September on the calendar for the bigger, more powerful stuff, but only if you've got the skills for it.
Rusty out.

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.
