The Lowdown
Alright, grab your board and let's look at what's coming up for Matinhos over the next couple of weeks. It's a bit of a mixed bag, but there are a few windows that should get a grin out of you.
First up, the water is sitting at 70°F which is much warmer than normal for this time of year. That's a nice surprise.
We've got a bit of a slow start, but there's some clean potential on the horizon. The weekend of the 15th and 16th is looking pretty average, with small, short-period swell and iffy winds. Don't get your hopes up for those days.
The first real standout comes on Monday morning, 17 August. There's a glassy, cross-offshore NW wind blowing at 3 mph, which is a proper winner for clean conditions. The wave energy is light, with a combined energy of only 337. Swell is 5 ft from the E with a 9-second period. It's not huge, but that clean, glassy surface will make it feel better than the numbers suggest. The break is a point, so it should handle that small east swell okay. With the break being very consistent, it's a good option for the intermediate plus crew.
The next one to circle is Monday morning, 24 August. The swell is up to 6 ft from the SSE, but the period is a short 7 seconds with a combined energy of 306. That's a bit of a messy, weak-feeling swell. The wind is a light cross-shore from the SSW at 3 mph, which is okay. Expect marginal conditions here, but it’s the biggest swell of the early run.
The best of the bunch, and the real standout, comes on Monday afternoon, 24 August. The swell drops a touch to 6 ft from the SSE, but the period jumps to 12 seconds, and the combined energy hits 921. That's a solid, moderate groundswell. The wind is a light cross-shore from the SW at 3 mph, which will keep it clean. A 12-second period groundswell of this size and direction, with light cross-shore winds, is a proper recipe for Matinhos. This is the one to plan for.
After that, conditions become more marginal and choppy through the rest of the week, with building onshore winds. There's a glimpse of clean surf on the morning of Friday, 28 August, with a glassy WSW wind, but the swell is only 3 ft from the ESE. It's a small, surfable option but nothing to write home about.
So, the clear winner is Monday afternoon, the 24th. Get it in the diary.

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.
