The Lowdown
Alright, mates, Rusty here. Let’s be straight with you—the next couple of weeks are looking pretty grim for surf around Matosinhos. We’ve got a long stretch of small, messy, wind-blown waves, and there’s not a whole lot to get excited about for a while.
We start off with nothing rideable. The first few days are tiny and chopped up. We’re talking weak energy, with the combined swell energy limping along in the low double digits at times (24, 25, 61). The swell direction is mostly from the WNW, not our optimum from the W, and there’s just no push behind it. It’s all onshore breeze and cross-chop, poor surf conditions across the board. You won’t want to paddle out for these ankle-biters.
There’s a slight bump in size on Friday the 21st, with the swell picking up a touch to 5ft on the afternoon, and the energy finally getting to a moderate 513. But it’s coming from the NW, with a cross-onshore wind at 19 mph, making it lumpy and a bit of a mess. We also start to see on Saturday the 23rd afternoon, another pulse to 5ft, but again with a fresh cross-onshore breeze. These are not clean waves; you’ll be fighting the wind more than riding the swell.
The pattern continues through the second week. There’s more size on offer towards the end of the month—like Saturday the 29th with 4ft and moderate energy of 264—but the wind is howling from the NNW at 28 mph in the afternoon. Honestly, with that kind of wind and a beach-and-reef setup, this looks more like a kitesurfing forecast than a paddle-surfing one. The beachies will be blown out.
The only flicker of promise comes on the very last couple of days. Monday morning, the 31st of August, we get a clean, glassy morning with a 3ft NW swell and an energy of 159, periods around 9 seconds. That’s a surfable wave, but very ordinary. The water temp is running about 0.9°F warmer than average, so it’s normal for this time of year.
Then Tuesday the 1st of September, we see the swell actually push up a bit, with 5ft in the morning and a stronger energy reading of 333. It’s still a bit onshore early, but the wind is light from the WSW. The afternoon picks up to 5ft with more energy (378), but the wind swings onshore from the NW, ruining any chance of it being clean.
So, there you have it. A long, flat, and blustery outlook for Matosinhos. There are no real standouts in this 16-day window. The only times worth even a glance are those final few mornings when the wind drops and we get a clean-ish 3ft to 5ft NW swell. But let’s be real, it’s not worth planning your week around. A blank run like this is more normal for the area, but it tends not to stay poor for long. Forecasts can change, so I’ll be keeping an eye on it. Until then, might be time to work on the pop-up on dry land or check the kite gear.
Stay salty.
Rusty.

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.
