The Lowdown
Alright folks, Rusty here. Let’s take a long, hard look at what Leca’s got cooking for us over the next couple of weeks.
First up, the water temp is sitting at 64°, which is a bit colder than normal for this time of year – about a degree off the average, so you’ll feel that slight chill.
To be brutally honest, the 16-day window is a tough one. There’s no standout session that’s going to have you calling in sick. The pattern is pretty grim for the most part, with a lot of onshore and cross-onshore winds messing up what little swell we get. The best we can hope for are a few small windows of clean-ish conditions, but you’ll have to pick your moments.
The best chance in the whole outlook is a brief window on Friday, the 28th of August. It’s not going to be world-class, but it’s the best of a bad lot. The morning has a solid 7 ft swell from the west, with a period of 10 seconds, swinging to a 7 ft WNW swell by the afternoon. The combined energy is moderate (834 in the morning, 872 in the afternoon). The wind swings onshore from the west in the afternoon, but the morning has a light cross-shore from the south (5 km/h). That’s the cleanest option we get. It’s a marginal call, but it’s the only size with a chance of a few workable ones. Expect a bit of a lumpy ride, but it’s the closest thing to a surfable wave we’ll see.
After that, the window goes quiet again. We get a few small, glassy mornings on Saturday the 29th and Wednesday the 2nd of September, but the swell is tiny (4 ft) and weak (133 to 169 combined energy). The waves will be there, but they’ll be soft and ordinary. The glassy conditions are a tease, but there’s just not enough push.
The rest of the first week and into the second is a write-off. You’ve got a lot of days with wind from the NNW, NW, and SW, all blowing cross-on or onshore, chopping up any small swell that shows up. The combined energy stays low, mostly under 300, and the swell heights hover around 3 ft to 5 ft with period under 8 seconds. That’s windswell, and it won’t be any fun.
We do have a little pulse arriving on Thursday, the 10th of September. The morning shows a 5 ft NW swell with a 9-second period and moderate energy (412). The wind is a light cross-shore from the north, so it’s actually clean. That’s the second-best option in the whole period. But again, the afternoon turns to onshore winds and it’s over. It’s a narrow window, and it’s far out – so don’t bank on it.
In summary, don’t get your hopes up. The best you’ll do is a scrap on Friday the 28th morning, and maybe a look at Thursday the 10th morning. For the rest, it’s small, weak, and messy. When the swell is that small and the wind’s all over the shop, it’s more of a kite surfing setup than a paddle surfing one. Sometimes it’s just like this around here, and the forecasts can change, but right now, it’s not looking flash.
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.
