The Lowdown
Alright folks, Rusty here. Let’s have a look at what Leca has in store for us over the next couple of weeks.
It’s a quiet start, but don’t write it off just yet. The first few days are flat and messy, with a cross-onshore breeze messing up any hope of clean waves. Wednesday the 2nd and Thursday the 3rd have tiny, weak swell, but the wind is all over the place. Thursday morning on the 3rd does go glassy for a moment, with a tiny 2ft WNW swell, but it’s barely enough to get excited about – more of a longboard paddle than a proper surf.
The real action doesn’t wake up until Sunday the 6th. That morning, the wind drops to nothing – glassy as a mirror – and a 3ft WNW swell rolls in with a solid 11-second period. The energy is moderate (264), and the wave comment says "expect good surf conditions." It’s clean, it’s got some push, and the period is long enough to give you proper groundswell lines. This is the standout of the whole forecast. Leca is exposed to the west, and the swell is coming from the WNW, which is a good match. The water is sitting at 69°, which is a touch warmer than normal for this time of year – a nice little bonus.
Monday the 7th and Tuesday the 8th see the swell build, with the 7th morning hitting 4ft at 12 seconds and strong energy (581), but the wind is cross-onshore and choppy, ruining the shape. For bigger-wave hunters, that’s frustrating. The 8th is similar – 4ft to 5ft NW swell, but the wind stays cross-onshore. It’s not clean enough for a recommendation.
The middle of the week, from the 9th to the 14th, is a mixed bag. There are a few moments of glassy conditions on the 11th and 15th, but the swell is small and weak. The morning of the 15th is glassy again with a 4ft WNW swell and moderate energy (259), giving you "expect good surf conditions." It’s a solid option if you’re patient, but it’s not the size of the earlier window.
The real gem for the experts is the morning of the 16th. Wednesday the 16th – that’s more than a week out, so treat it as promising but not locked in – the forecast shows glassy conditions, a 5ft WNW swell, a 12-second period, and very strong energy (560). The wave comment says "expect very good surf conditions." That’s the kind of morning that gets the heart pumping. The wind is light from the NNW, offshore enough for Leca, and the swell is solid. If you’re an experienced surfer, mark that date.
For beginners, the 5ft on the 16th might be a bit too much, but the 3ft to 4ft glassy mornings on the 6th and 15th are perfect for learning. Crowds are often at Leca, so expect some company, especially on the good days.
Overall, the first week is a bit of a slow burn, but the second week has two clear standouts – the morning of the 6th and the morning of the 16th. The 16th is the biggest and best on paper, but the 6th is closer and more reliable. Keep your eyes on the long-range forecasts for the 16th.
Rusty.

Information about the Leca Surf forecast
The above surf forecast table for Leca provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Leca can be found by selecting the local surf guide option on the grey menu. Our Leca 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 (Leca) 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 Leca 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.
Leca is 1 km (1 miles) from Matosinhos. If you plan a holiday in Douro and Minho, look for hotels and other accommodation in Matosinhos. Matosinhos has rooms for a wide range of budgets as well as car hire and transport links.
