The Lowdown
Right, folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Honestly, it's a bit of a grim start. We're looking at a long stretch of pretty poor conditions here at Matosinhos. For the first few days, from Sunday afternoon through to Thursday morning next week, it's a write-off. The wind is all over the shop, mostly cross-onshore, and the swell is weak and messy. The water is a touch cold for this time of year, sitting at 65°, which is a bit colder than normal.
Things start to get a bit more interesting on Friday, August 28th. The morning brings a proper pulse of swell from the WNW rocking in at 8ft with a long 11-second period. The combined energy is a massive 1143, which is very strong. However, that's just too big for this spot – the forecast says it's too big for the break. If you're a seasoned charger, you might have a look, but for most of us, it's a no-go. The wind is light cross-onshore, so it's not completely blown out, but the size is the issue.
The following Saturday morning, August 29th, offers a little window. The swell drops back to 4ft from the WNW, with a 9-second period. The wind is a light, clean cross-off from the NNE, so the surf will be clean. The energy is a moderate 186. It's not going to be anything to write home about, but it's surfable.
Then we hit another dry spell. Monday, August 31st, the morning has a 4ft WNW swell, but the wind is cross-shore, making it ordinary. The days just slide by with poor conditions.
The one true standout is much further out. On the morning of Sunday, September 6th, over a week away, we've got a small but clean option. The swell is 3ft from the WNW with a very long 11-second period, giving it a moderate energy of 305. The absolute key here is the wind: it's glassy. Dead flat, no wind. That is a rare treat for a beach and reef setup. The swell direction is a touch west of the optimum, but it could still offer some clean, lined-up waves for a longboard or a funboard. It's a promising one, but it's a long way out, so keep an eye on the charts.
That's the long and short of it. A tough start, one big day for the brave, and a glassy whisper of hope right at the end.
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.

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.
