The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Right off the bat, we’ve got a bit of a slow start. The first real chance to get wet comes on Friday the 21st, but honestly, it’s nothing to write home about. The main event for this whole forecast period is shaping up for Monday the 24th. That afternoon, we’ve got a serious pulse of energy from the south-southeast hitting the Matinhos point. We’re looking at 5ft swell with a very long period of 16 seconds, and the wind is going glassy. That’s a recipe for absolute perfection. The combined wave energy is pumping at 941 (moderate to strong energy), and with that long period, expect well-shaped, powerful lines. This is the standout session of the whole window. The water is a much warmer than normal 71°F, which is a bonus.
The Tuesday morning the 25th will still be fun with glassy conditions and a 3ft, 13-second swell (373 energy), but it’s a step down from the peak. After that, things get a bit messy with onshore winds and smaller, less consistent swell through the rest of the week.
Looking further ahead into September, there’s another spike in size on Wednesday the 2nd and Thursday the 3rd. Swell heights jump to 6ft and 7ft from the south-southeast, but the period is a much shorter 8 seconds, and the wind is mostly cross-onshore or onshore. The energy is there (840 on the 3rd morning), but the quality won’t be there for paddle surfing. With that much chop and short-period swell, it’s looking more interesting for the kite surfers than the paddle crew. A better call comes Friday morning the 4th with glassy conditions and a 3ft, 13-second SSE swell (440 energy) – a clean, if smaller, option.
So, to sum it up: the clear winner is Monday afternoon the 24th at Matinhos. That’s your one to circle. Everything else is a mix of okay windows and periods to sit out.
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.
