The Lowdown
Alright folks, Rusty here. Let’s take a look at what Leca has in store for us over the next couple of weeks. I’ll be straight with you – it’s a bit of a mixed bag, with some real gems hidden in the first few days, but then a long stretch of nothing much to write home about.
The best surf on offer is in the early mornings, when the wind goes glassy and the conditions clean right up. The standout period is the first few days, especially Wednesday the 12th and Friday the 14th. Wednesday morning the 12th is the pick of the bunch. You’ve got a clean 3 ft swell from the west with a period of 9 seconds, and the wind is glassy. The water temp is about average for this time of year, so nothing to complain about there. The combined swell energy is moderate at 122, which is enough to get you into a few fun ones. It’s a consistent spot, exposed to the west, which is right where the swell is coming from. Expect crowds to be possible – it’s a popular one when it’s good.
Thursday morning the 13th looks similar, with a 3 ft west swell and offshore wind, but the score is a bit lower. It’s still surfable, but Wednesday just has that little extra magic.
Friday morning the 14th is another solid shout. The swell is 3 ft from the west-northwest, period 9 seconds, and the wind is glassy again. Combined energy is 168, so it’s got a bit more push than Wednesday. It’s a consistent break, so you can bank on a few waves.
After Saturday the 15th, things get messy. The swell picks up, but the wind turns onshore and strong, making it choppy and blown out. Saturday morning might be tempting with the 5 ft swell, but a 12 mph cross wind makes it a no-go. Sunday afternoon the 16th is a write-off. From there, it’s a long dry spell. There’s a gap of several days – from Saturday the 15th all the way through to Sunday the 23rd – where the surf is either too small, too windy, or too messy to be worth paddling out. You’ll see some small glassy waves again on Sunday morning the 23rd, but the period is only 6 seconds, so it’s weak and short. The combined energy is only 78, so it’s not going to get your heart racing.
The last possible chance is Tuesday morning the 25th of August, with a 4 ft west-northwest swell and a 9-second period, but the wind is cross, and it’s described as marginal. The combined energy is 385, which is strong, but the conditions just aren’t there.
So, in short: your best bet is Wednesday morning the 12th or Friday morning the 14th. Get out there early, enjoy the glassy conditions, and make the most of it before the wind turns ugly. After that, it’s a waiting game.
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.
