The Lowdown
Alright, grab your board. Rusty here, breaking down the Matinhos forecast for the next couple of weeks.
It starts off a bit slow. The first real go is Monday the 17th, with flat-calm wind and a chest-high (4ft) swell from the east. The water is a warm 21°, a couple of degrees above normal. The combined energy is moderate (253), and with glassy conditions, it’s the cleanest it gets that day. Don't sleep on the morning session, because the wind turns onshore and ruins the afternoon.
After that, it gets thin. Tuesday the 18th starts glassy but the swell drops to a weak 3ft, and then it’s mostly onshore or messy winds right through to Saturday the 22nd. Saturday morning offers flat calm wind again, but the swell is only waist-high (3ft) from the SSE. It's doable, but nothing special.
Sunday the 23rd is a better call. The morning is clean and glassy with a waist-to-chest high SSE swell (3ft) and moderate energy (211). The period is up to 9 seconds, giving it a bit more shape. A solid, clean option.
The real highlight, though, is the last day of the outlook. On Monday the 31st of August, the morning brings a strong 6ft SSE swell with a very long 16-second period, cranking the energy up to strong (1782). That's proper groundswell. For a point break like Matinhos, those long periods mean long, drawing lines and long waits between sets. The wind will be a light cross-onshore, so it won't be perfectly smooth, but the power will be undeniable. For experienced surfers, this is the day. That swell is well over 5ft, so it's expert territory.
Tuesday the 1st of September still has a long-period swell (4ft at 13 seconds) and moderate-to-strong energy (615). Again, a light cross-onshore wind, but there will be waves.
To sum it up: the first week is a write-off for quality. Your best bets are that clean Sunday the 23rd for an easy-going session, or if you've got the skill, the big, long-period swell on Monday the 31st. Just expect crowds, as Matinhos is often busy.

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.
