The Lowdown
Alright, Rusty here, and I’ve got the lowdown on the next couple of weeks at Matinhos.
This is a classic point break setup, very consistent, and it’s exposed to the south swell window. The water is sitting at 70°, which is much warmer than normal for this time of year – you’ll be in boardshorts and maybe a spring suit, no need for anything thick.
The week kicks off slowly. The first real window is Wednesday afternoon the 12th, with a small 4 ft SE swell, but the wind is glassy from the ESE at just 3 mph. That’s a beautiful start, with clean conditions and moderate wave energy (341). For Thursday morning the 13th, the swell drops to 3 ft from the SSE, but the period stretches to 15 seconds, giving it a lovely groundswell feel. The wind is dead calm – glassy perfection – and the energy jumps to 422. That’s a standout session for the early birds, but it’s a short window because Thursday afternoon turns messy with a cross-onshore wind.
Friday the 14th offers a couple of glassy windows, but the swell is small (2 ft to 2 ft) and there’s light rain around. Saturday morning the 15th looks promising again: 4 ft SE swell with an 8-second period, glassy wind from the north, and moderate energy (309). That’s a fun little window for a point break that handles short-period stuff well. Sunday morning the 16th is similar – 4 ft ESE swell, glassy, clean – but the period is short, so it’ll be a bit mushy.
There’s a real lull from Monday the 17th through to Saturday the 22nd. The swell stays small, under 3 ft, and the wind is mostly cross or onshore. The energy drops into the double digits (as low as 84), and the waves are poor to ordinary. It’s a flat spell where you’d be better off waxing your board and waiting.
Then, Sunday the 23rd is where it gets interesting. That morning, we see a 6 ft SSE swell with a 10-second period, glassy conditions from the WNW, and energy at 696 – that’s strong. This is the standout of the whole run. The wind is zero, the waves have size and power, and the point will be lining up beautifully. But heads up: 6 ft is pushing into intermediate territory, so it’s not for total beginners. The afternoon is a little more marginal with a cross-onshore wind, but the morning is the session to lock in.
Monday the 24th and Tuesday the 25th still have solid energy (535 to 568) with 4 ft SSE swell and periods of 13 to 14 seconds, but the winds are cross or cross-onshore, so it’s a bit messed up. The quality drops off. Wednesday the 26th and Thursday the 27th see the swell fading and the wind turning questionable, with light rain and cross-shore breezes.
Overall, the best call is Sunday morning the 23rd – that’s the one to circle. The early windows on Thursday the 13th and Saturday the 15th are also worth a paddle, but the real standout is that 23rd morning session. Everything else is a waiting game.
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.
