The Lowdown
Right then, let's take a look at what's on offer for Leca over the next couple of weeks. Straight up, it’s a pretty lean run, with a lot of ordinary conditions to wade through, but there are a couple of sessions that'll make the wait worthwhile.
We’re looking at a predominantly exposed beach break that needs a good W swell and some decent luck with the wind. The water temp is sitting about average for this time of year, so nothing wild there.
The first real highlight looks to be the Sunday morning, August 23rd. We’ve got a clean 4ft groundswell rolling in from the W at 11 seconds – that long period will bring some nice energy into the waves, with moderate combined energy (385). But the real story is the wind: glassy conditions. That means the ocean will be a mirror, and the waves will be as clean as it gets. For a beginner-friendly spot, this is as good as it gets, just be aware that a long period swell at a beach break can sometimes stand up a bit straight.
Then we jump ahead to a promising long-range call. Saturday morning, August 29th is shaping up nicely. We’re looking at a 4ft W/NW swell with moderate wave energy (272) and, once again, a glassy, flat-calm surface. That is prime stuff for Leca. For a spot that’s exposed, clean conditions like this are the key to a great session. Keep an eye on the forecasts as we get closer, though; it’s a ways out.
Outside of those two windows, there’s a lot to ignore. The rest of the first week is plagued by poor to marginal conditions, mostly onshore or side-shore winds and choppy seas. There’s a couple of mornings with small clean swell, like Sunday August 30th, but at 2ft, the energy is pretty weak (112) and it’s more of a longboard cruise.
For the second week, from the 31st of August onwards, it's even quieter. The combined swell energy drops well below 100, and it’s a constant story of moderate to fresh cross-shore winds and lumpy conditions. There’s no real standout here, just small, average surf with poor quality. It’s a blank run on the horizon.
So, sharpen your fins for Sunday the 23rd and Saturday the 29th if the weather gods play ball. The rest of the time, the surf is just not worth the paddle out.

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.
