The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for Matosinhos over the next couple of weeks.
Honestly, it's a bit of a flat spell to kick things off. We've got a few tiny, weak pulses but nothing worth paddling out for until Thursday morning. The waiting game is on. The first real chance you’ve got is on Thursday 20th, with a little bump of 2ft from the WNW, but what makes it interesting is the glassy wind. Dead calm. That combined swell energy is weak at just 94, so you won't be pulling into anything heavy, but for a small board or a foamie, it'll be clean and cruisy. The water temp is sitting at 68°, which is pretty normal for this time of year.
After that, the energy picks up a bit, but the wind turns ugly. Friday 21st morning has 4ft from the NW, with light cross-shore wind, but it's only rated as marginal. The afternoon gets blown out by a brisk NNW breeze at 22 mph pushing the swell up to 5ft with a combined energy of 513 – that's moderate to strong energy, but it'll be a lumpy, choppy mess. Not for the faint of heart or the shortboard.
Saturday 22nd morning gives us another brief moment of glass, with 3ft from the NW. It's weak energy (160) but clean. The afternoon turns onshore and messy.
We hit another rough patch from Sunday 23rd all the way through Monday 31st. Lots of onshore wind, cross-onshore chop, and generally poor surf conditions. There's a glimmer on Thursday 27th morning with 4ft from the WNW and a light cross-shore, but the period is short (8 seconds) and the conditions are still considered poor.
Now, if you've got patience, the second week shows a bit more promise but it remains uncertain. Monday 31st morning brings 5ft from the WNW with a period of 10 seconds and a decent combined energy of 464. The wind is a cross-offshore from the SSE at 12 mph, so it could actually be clean. That one has marginal potential.
Then on Wednesday 2nd of September, we finally get a standout window. The morning shows 4ft from the WNW with glassy conditions. That's the only window in the entire 16-day run that gets a solid rating. The wind is light from the SSE, the surf will be clean, and the energy is moderate (214). It's a real chance for some fun, lined-up waves at Matosinhos. Just be aware, this spot is listed as "fairly consistent" and crowds are "often" around, especially when it's clean.
The last few days of the forecast see the size drop back down and the wind swing onshore again, so that Wednesday 2nd is your best bet. Keep an eye on it.
Rusty, signing off.

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.
