The Lowdown
Alright, surf is looking pretty grim for a while here, folks. The next week and a half is going to be a real test of patience. The good news is, it’s not looking like a flat spell that’s here to stay. There are a few windows of opportunity if you’re keen and flexible, but you’ll have to pick your moments.
First up, the water at Leca is sitting at 64°, which is a bit colder than usual for this time of year. So, you’ll want the thick suit regardless.
For the weekend and into the start of next week, it’s pretty much a write-off. We’ve got some small, weak swell around, but the wind is just going to chop it all up. Friday the 11th is a no-go with onshore junk. Saturday the 12th sees a tiny pulse but it's too messy in the afternoon. There might be a brief look on Sunday morning the 13th when an ESE offshore wind cleans up a 3ft WNW swell, but the period is a bit short and it’s nothing to get excited about. Monday the 14th has a glassy morning with a weak 2ft swell, but it's really marginal.
Then we hit a proper lull. From Tuesday the 15th through to about Wednesday the 23rd, it's mostly small, messy, and wind-blown. There’s a push of bigger swell on the 16th, but it’s accompanied by strong onshore winds, making it a complete mess. Not worth the drive.
Finally, things start to look interesting on Thursday the 17th. The morning brings a clean 4ft NW groundswell with a 11-second period and a light cross-offshore wind from the ENE. That’s our first real standout. The energy is moderate, and the swell direction is lining up with what Leca likes. It won’t be epic, but it’ll be the best surf we’ve seen in days and should offer some fun, clean lines.
After that, we get another stretch of pretty ordinary conditions until Sunday morning the 20th. It's clean with a light cross-offshore wind and a 3ft NW swell, but it's pretty weak. The next real highlight doesn't show up until Tuesday the 22nd. The morning session looks good with a clean 3ft, 12-second WNW groundswell and a light cross-offshore breeze. The energy is moderate, and conditions should be clean and rideable. It's a promising morning.
But the true standout of this entire forecast is Wednesday morning, the 23rd. We’ve got a bigger pulse of 2ft swell but with a very long 15-second period, and it’s glassy with no wind. The swell energy is strong and the direction is perfect. This is the one to point for. It’s a two-week wait, so take it with a grain of salt, but it has all the makings of a proper glassy, long-period groundswell session. It’s the kind of morning that makes the wait worthwhile.
Everything after that fades back into the small and messy category. The 24th and 25th are not worth your time, and the 26th has a small clean morning but nothing with any push.
So there you have it. A long, dry spell with two brief flashes of hope on the 17th and 22nd, and one real standout to wait for on the morning of the 23rd. Keep your eyes on that one.

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.
