The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Leca. We’re in for a bit of a mixed bag over the next couple of weeks, so patience is going to be key. There’s no surf to speak of right at the start, so we’ll be waiting a few days before things get interesting.
The first real chance to get wet comes on Monday, the 31st of August. The morning session is the one to aim for. We’ll have a 4ft swell out of the WNW, with a period of 10 seconds, and the wind is a light cross-offshore. That’s going to keep things pretty clean. The combined energy is moderate at 284, so there’s a bit of push behind it. It’s not the biggest swell, but it’ll be manageable for the beginner crew out there.
Tuesday the 1st of September is a bit of a letdown. The morning is cross-shore and lumpy, and the afternoon just gets chopped up. Not worth paddling out for.
Now, Wednesday the 2nd of September, the early morning is a real gem. The wind goes glassy, and even though the swell is only 3ft from the NW with a period of 8 seconds, the glassy conditions make it rideable. The energy is weak at 91, so it’s small, but it’s clean. For a beginner-friendly spot, this is a nice little window.
Things go quiet again until the 5th of September, Saturday morning. That’s our standout. A 4ft groundswell from the WNW, rolling in with a very long period of 13 seconds. The combined energy jumps to 486, which is strong. The wind is a clean cross-offshore from the NNE. This is the pick of the forecast. The longer period means better shaped waves, more energy, and longer lulls. Keep in mind that with a period over 15 seconds (which this isn’t quite), it can break straight at beach breaks, but at 13 seconds, it should be fun. The crowds are mentioned as “often” here, so expect some company.
After that, we hit a dry spell. From the 7th through to the 12th of September, it’s mostly poor conditions with small, weak swell and onshore winds. Not much to work with.
The next notable window is Sunday the 13th of September. The morning session is glassy, with a 4ft swell from the NW at 8 seconds. The energy is moderate at 236. It’s clean, but the period is a bit short, so the waves will be a bit weaker and more crumbly. A decent session for a Sunday morning.
The very last call is Monday the 14th of September. The wind is dead calm, glassy, with a 3ft groundswell from the NW at 11 seconds. The energy is moderate at 217. It’s small but pristine. A nice way to wrap up the outlook.
So, to sum it up: the standout is the Saturday morning of the 5th of September. That’s the one with the most size, clean wind, and long-period energy. The Wednesday morning of the 2nd of September is a close second for the glassy, small conditions. The rest of the time, you’ll be waiting.
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.
