The Lowdown
Alright, Rusty here. Gotta be straight with you – it’s a lean stretch ahead for Leca. The whole 16-day window is a tough one, with nothing really getting the blood pumping. We’ve got a long, drawn-out run of small, weak, and often messy surf, so you’ll want to keep your expectations in check.
The water temp is sitting right around average for the time of year at 66°, so no surprises there. The problem is, for the first few days, we’re looking at tiny 1 ft to 2 ft swells with cross-onshore winds messing up the surface. The combined energy is weak, barely cracking 30-79 (moderate wave energy), and the wave comment is just "poor surf conditions" – not a lot to get excited about. This vibe sticks around through the end of July and into the start of August.
The first real glimmer comes on the morning of Tuesday, August 4th. It’s still small, only 3 ft from the west with an 8-second period, but the wind goes glassy. That means the surface will be clean, and the combined energy bumps up to 100 (moderate wave energy). The wave comment shifts to "surfable waves but very ordinary conditions." It’s not a standout by any stretch, but it’s the best we’ve seen so far. You’ll be on a longboard or a funboard, just enjoying being out there.
After that, we slide back into a pattern of small, weak swells. The morning of Wednesday, August 5th offers another glassy window with 2 ft from the west, but the energy drops back to 70. It’s clean, but tiny. Then we get a few days of slightly bigger, but choppier, surf. The morning of Saturday, August 8th sees 3 ft from the west, but the wind is cross-onshore, spoiling it.
The most interesting morning is Sunday, August 9th, with another glassy morning. The swell is back down to 2 ft from the west with a 6-second period, so it’s really small, but the energy is only 42. It’s another session for the log, if you’re desperate.
The second week looks even more grim. The morning of Tuesday, August 12th has 3 ft from the west with a 9-second period, and the energy hits 100 (moderate wave energy), but the wind is light cross-onshore, leaving those little ripples on the surface. The wave comment is again "poor surf conditions." There’s no real standout to chase.
Honestly, the best you’re going to get here is the glassy mornings on August 4th, 5th, and 9th. The swell is tiny, but it’s clean, and that’s the best we can say. If you’re a beginner, those are the days to go. For anyone else, it’s a frustrating wait.
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.
