The Lowdown
Alright, Rusty here. Let's have a look at what the next couple of weeks have in store for us.
Honestly, mate, it’s a bit of a tough stretch. The forecast is showing a long gap of flat, messy, and frankly pretty ordinary conditions. I’m not seeing much to get excited about for a good while. The first real chance of anything decent doesn’t pop up until the morning of Thursday, August 27th, and even then it’s nothing to write home about.
So, from now until the 27th, you’re looking at a lot of small, weak, and wind-affected surf. There’s a pulse of bigger energy on Thursday afternoon the 20th, with a combined swell energy of 292, but it comes with a fresh cross-onshore wind at 19 mph, making a mess of things. The water temp is about average for the time of year, nothing unusual there.
The one true standout in this entire 16-day window is Friday morning, August 28th at Matosinhos. The stars finally align: a glassy, offshore breeze from the NE at just 3 mph, and a clean 4ft groundswell from the WNW with a period of 9 seconds. The combined energy is a solid 216, so there’s a bit of punch behind it. This is your best shot. The wind will be perfect, the waves will have some shape to them, and it’ll feel like a proper surf. I’d be glued to the forecast for that one, because it’s the only solid window. The rest of the 28th gets messy again by the afternoon.
After that, the following Sunday morning the 30th also starts glassy but with less size and energy at 4ft and 192. For the rest of the forecast, it’s mostly blown-out, choppy, and small.
So, keep the spirits up for that Friday morning the 28th. The rest of the time, you might be better off checking the wind forecast or just giving it a miss.
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.
