The Lowdown
Alright, Rusty here. Let’s break down the surf at Matinhos.
You’ve got some smaller clean windows early on, but the first couple of days are a grind. Monday the 10th is blown out with a 5ft S swell and cross-onshore wind – not worth the paddle. Tuesday and Wednesday morning still look messy.
Wednesday morning, the 12th is the first real bright spot. Glassy flat water, 4ft SE swell with a 12-second period. Clean, fun, and rideable for the intermediate crowd. Water is running about 70° – almost 5° warmer than normal, real unusual.
Thursday morning the 13th is another glassy morning – 3ft SSE swell with a 15-second period. That’s proper groundswell energy (414) that will wrap nicely down the point. Long waits between sets, but the waves will have power and shape.
Friday and Saturday mornings (14th and 15th) stay clean but drop to 3ft – good for a longboard or a fish.
The standout to circle is Tuesday morning, the 18th. A solid 6ft SSE swell, short 8-second period but strong energy (653). Glassy first thing. That’s pushing into intermediate territory – fine for solid surfers, but a bit much for beginners. The afternoon wind ruins it, so be out early. Over a week away, but worth watching.
The absolute best bet is Tuesday afternoon, the 25th. Long-range, but looks special. 3ft SSE groundswell with a 16-second period – that’s a super long period for the point. Energy is massive (1162) and the wind is glassy. Excellent conditions for experienced surfers. If that sticks, Matinhos point will have long, powerful lines. Circle that date.
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.
