The Lowdown
G’day, this is Rusty. Gotta be honest with you – the next week and a half is pretty ordinary, but there’s a real nice window of clean, building swell late next week that looks like the pick of the bunch.
We kick things off with a tiny pulse. Tuesday morning at Matinhos (point) is clean with glassy conditions and a little 3ft east swell pushing through, period a short 8 seconds, combined wave energy reading moderate (142). It’s surfable but very ordinary. That’s about the best we see for a while. The water temp is about average for this time of year.
Then things go flat and messy. Wednesday through to the end of the week we’ve got tiny swell under 3ft, mostly poor winds – cross-onshore, choppy – and weak energy dropping to 45-79. Not worth paddling for. A real dry spell.
Saturday the 22nd shows a little glimmer: a 3ft south-southeast groundswell, period 10 seconds, clean off the north wind in the morning, energy moderate (194). Still small, still ordinary, but at least you’ll get a clean crumbly wave.
Sunday the 23rd gets a slight bump – 4ft from the SSE, period 9 seconds – but it’s onshore and light rain. Marginal at best.
Now here’s where it gets interesting. Monday the 24th is the standout. The swell builds to 4ft from the SSE, period jumps to 13 seconds – proper groundswell – and it’s glassy in the morning. Combined wave energy hits strong (466). This is a clean, chunky point wave with good shape. The longer period means it’ll line up nicely at Matinhos, but it’s already over 5ft so keep it in mind for intermediate-plus surfers. Crowds are often here, so expect company.
Tuesday the 25th keeps the quality: 4ft SE groundswell, period 14 seconds, glassy again in the morning with calm winds. Energy still strong (473). Another excellent morning for groomed, peeling waves.
After that the swell slowly fades through Wednesday and Thursday – 2ft with clean cross-off winds – surfable but dropping.
The very end of the forecast, around Tuesday 1st September, ramps up to 6ft from the SSE short period (7 seconds) but it’s cross-onshore and light rain. That’s a messy, blown-out mess – better left alone, or maybe kite surfers could have a look.
All in all, target Monday 24th and Tuesday 25th mornings for the cleanest, most powerful surf of the period. Don’t get excited for the rest.
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.
