The Lowdown
Right, grab a coffee and listen up. Rusty here, looking over the next couple of weeks for our patch.
First up, the water is properly warm at 69°F, which is much warmer than normal for this time of year – a real treat to start with.
We’ve got a bit of a slow burn to start. No real standout surf until Saturday morning the 15th, but that first session is a beauty. Matinhos will be the place. It’s a consistent point break, exposed to the south-east, and we’ve got a clean 4ft swell rolling in from the SE. The wind is glassy – dead calm – so expect clean, lined-up walls. The energy is moderate (357), and with that offshore wind, it’s going to be a great morning for intermediate surfers. Crowds are likely, but on a Saturday morning with decent waves, that’s just part of the deal.
Saturday afternoon the 15th gets a bit messy with a cross-on breeze, so the morning is the clear winner.
Sunday morning the 16th is another cracker. Glassy conditions again, with a 5ft swell from the ESE. It’ll be a fraction bigger and still clean. Another solid morning for a paddle.
Monday the 17th starts with zero wind and a glassy 4ft easterly groundswell. The period hits 9 seconds, so there’s a bit more push and shape to the waves. A calm, clean start to the week.
After that, the next few days drop off hard. From Monday afternoon through to Friday the 21st, the swell drops and the winds get messy. It’s a real flat spell, with wave energy dropping into the double digits (54-85). You’d be struggling to get a ride.
Now, here’s where it gets interesting again. Look at Sunday the 23rd. We get a big pulse of swell – 6ft from the SSE with strong to very strong energy (488). But, the wind is a cross-on breeze. It’s going to be powerful and fat, not clean. This one is for the experienced crew only, as it’s over 5ft and the chop will make it tricky.
The long-range stuff is a bit of a mixed bag but has potential. The standout in the second week is Monday 26th August. It’s not big, only 2ft, but it’s a long-period 12-second swell from the SSE with a clean, cross-off wind. That’s a proper groundswell for the point, and the conditions will be clean. The energy is still moderate (217), but the quality of the waves will be there.
Then, Saturday 29th August afternoon looks promising. A 4ft easterly swell with a cross-off breeze and clean conditions (218). That’s a solid afternoon session to close the window.
So, the biggest call is Saturday morning the 15th for the combo of clean, glassy waves. The long-range hope is Monday 26th August for clean, long-period lines on the point, but you’ll need your log out for that one.
Stay stoked.
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.
