The Lowdown
Alright, Rusty here again, now in feet and Fahrenheit. The next couple of weeks start slow. Small surf, average conditions. Then about nine days out, the energy cranks up. The real standouts are at the end of the run, but you gotta wait for it.
First surfable day is Sunday the 16th of August, early. Matinhos (point) has a glassy 4ft swell from the ESE, period of 8 seconds. Wind is dead calm, so it’s clean. Combined wave energy is moderate (261), nothing huge. Water temp is 69°, which is about 5° warmer than usual, so it’s noticeably warm.
Monday the 17th morning is similar: glassy, 5ft from the east, still 8 seconds. Energy bumps to moderate (302). Still small, still clean. Tuesday the 18th morning is smaller at 4ft, glassy, energy drops to 177. Surfable but not exciting.
Wednesday the 19th morning gets an offshore wind from the NNW, but the swell is only 3ft, energy weak (108). Clean, but tiny. From Thursday the 20th through Friday the 21st, it gets really small and poor. Swell drops to 2ft to 2ft, period down to 7 seconds. Not worth it.
Then there’s a gap of a few days with poor conditions. Saturday the 22nd shows a pulse from the SSE with a 9-second period and energy (150), but onshore wind ruins it. Sunday the 23rd brings a bigger 4ft swell from the SSE with a long 13-second period and strong energy (522), but a moderate cross-onshore breeze makes it choppy. Not for paddle surfing.
The real standout starts Monday the 24th of August. We get a 4ft SSE groundswell with a very long 15-second period and strong energy (601). Wind is light cross-shore, so not perfect, but that period is rare. Tuesday the 25th is the gem: glassy morning and afternoon, 3ft but with a 14-second period, energy (328 to 330). Clean, glassy, and that long period means shape and push. That’s the one.
Wednesday the 26th stays clean with light offshore wind and a 13-second period, though the swell drops to 3ft. Then Thursday the 27th morning sees a solid 5ft from the SE, period 9 seconds, and strong energy (607). Light cross-offshore wind keeps it clean. That’s a big step up.
Friday the 28th is another contender: 6ft in the morning from the east, 6-second period, glassy. Energy moderate (294). The afternoon goes glassy again with 5ft from the east at 8 seconds. Size and perfect wind. This is the biggest, cleanest swell of the whole run.
After that, Saturday the 29th gets messy. But Sunday the 30th finishes strong: glassy morning and afternoon, 3ft from the east, 8-second period, energy moderate (228 to 200). Clean and fun.
Best on offer: the glassy Tuesday the 25th with that long-period groundswell, and the big, clean Friday the 28th morning. Both are worth the wait.
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.
