The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for Matosinhos over the next couple of weeks. I gotta be straight with you, it's a pretty bleak run ahead for the most part. We're looking at a lot of small, weak, and messy conditions with very few windows of clean surf.
The water temp here is sitting right around 68°, which is pretty much normal for this time of year, so the wetsuit choice stays the same.
Looking at the immediate forecast, we kick off Saturday the 15th of August with a bumpy and choppy 5ft NW windswell. That's a no-go with a strong 15 mph cross-onshore wind. We get a brief moment of hope on the morning of Sunday the 16th of August. The wind goes glassy, dropping to 3 mph from the NNE, and we've got some tiny 3ft NW swell. The energy is weak at only 95, but it's the cleanest the waves will be for a while. Monday the 17th of August morning also sees glassy conditions with a light SSW breeze and that same 3ft NW swell, so if you're desperate for a longboard, those are your only real options. After those mornings, it's back to small, onshore junk.
We then hit a long, dry spell. From Tuesday the 18th right through to Friday the 21st, the swell is tiny, the winds are mostly onshore or cross, and the scores are zero. Just a whole lot of nothing happening. The energy levels are pathetic, mostly below 100. On Friday the 21st, we see a little bump in energy to 188 with a 3ft NW swell, but a 18 mph cross-onshore in the afternoon will ruin any chance of a wave.
The next real standout doesn't show up until the very end of the forecast period, and it's a big one. On Saturday the 29th of August, the morning is looking *very* interesting. We've got a solid 7ft NW swell rolling in, with a strong energy reading of 965. But the real kicker is the wind: it's glassy, coming from the WNW at just 3 mph. That's the kind of morning you wake up early for. Now, that size is going to be way too much for beginners, this is strictly for the experienced crew. The period is a short 8 seconds, so it's windswell, not a clean groundswell, but with those perfect winds, it'll still be a ton of fun at Matosinhos. The forecast says the swell might be too big for this break, so expect it to be a bit of a washing machine, but with clean conditions, the better surfers will find some wedges. This is the best option in the whole 16-day outlook. After that, the swell drops off again.
So, the summary? You have two tiny windows of clean, small waves on the 16th and 17th of August mornings, and then one epic, expert-only morning on the 29th of August. The rest is pretty much a write-off for a paddle.
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.
