The Lowdown
Alright folks, Rusty here with a look at the waves on the line-up for Matosinhos.
Well, right out of the gate, it’s a bit of a slow start. The forecast is pretty flat for the first bit with nothing worth paddling out for. We’ve got a bit of a wait on our hands.
The first real flicker of hope arrives Wednesday morning, August 12th. The ocean decides to give a little. We're looking at a small, clean 3ft swell coming out of the West, with a long period of 9 seconds. The moderate wave energy is there (124) but the real story is the glassy conditions. With a WSW light breeze at just 3 mph, it’ll be smooth as a mirror. It’s surfable, but it’s very ordinary—a gutless little wave that’s more about getting the board wet than getting a barrel.
The window widens slightly Friday morning, August 14th. We get a similar setup: another glassy morning with a WSW wind at 3 mph. The swell bumps up just a hair to 3ft out of the WNW, with a moderate energy reading of (193). The water temperature is sitting at a balmy 70°F, which is a full 4°F warmer than normal for this time of year—a real treat for a morning session.
The most promising, yet still only marginal, moment looks to be Saturday morning, August 15th. The swell pushes up to 5ft from the NW, and the energy jumps to a moderate 221. But that's where the good news ends. The wind is light and cross-onshore, not ideal, and the period is a short 8 seconds. There's more push, but it's not going to be the cleanest.
Honestly, after that, the next two weeks are a write-off. We get a nasty run of strong cross-onshore winds, mostly from the NNW, that just tear the surface apart. It gets lumpy, messy, and generally unpleasant for a paddler. The swell sticks around at waist to chest high but the wind just kills it. The biggest glimpse of size comes Saturday afternoon, August 15th, with a 8ft NW swell and a wave energy of (746), but it's paired with a 22 mph cross-onshore wind. That’s a raw, blown-out mess.
On Thursday morning, August 20th, you might see a bit of something with a 5ft NW swell, but it’s heavy with a cross-shore breeze. The energy is there (346), but the quality isn't. For the whole second week, it's largely a case of wind and chop ruling the roost. If you are desperate for a paddle Thursday morning, August 20th is the only thing that might be worth a check, but don't hold your breath.
The standout, if you can even call it that, is Saturday morning, August 15th for having the most size, but it’s a raw, imperfect wall of water. For the cleaner stuff, hit Wednesday morning, August 12th or Friday morning, August 14th for the glassy windows, even if the waves are small. It’s a tough run for Matosinhos.
Stay stoked, or at least, stay patient.

Information about the Matosinhos Surf forecast
The above surf forecast table for Matosinhos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Matosinhos can be found by selecting the local surf guide option on the grey menu. Our Matosinhos 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 (Matosinhos) 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 Matosinhos 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.
