The Lowdown
Alright, Rusty here. Let’s talk about what we’ve got on the cards for the next couple of weeks.
The outlook is pretty flat and uninspiring. We’re looking at a long, drawn-out period of small, weak swell, with only brief moments where it’s even worth thinking about a paddle. Most of the time, the onshore wind messes things up. This isn’t going to be a classic run.
For the next few days, there are a few windows. The best early call is Sunday morning, August 9th at Leca. The swell is only 3 ft from the west, with a short period of 7 seconds, so the energy is weak (86). But the real story is the wind – it’s glassy, dead calm. That’s a major positive for a small wave. It’s a consistent beginner break that’s exposed to the west, which is the right direction. The water temp is about average for this time of year. You can get a few little ones, but you won't be missing much if you sleep in. The afternoon goes straight to junk with a 12 mph cross-onshore.
The mornings on Wednesday, August 12th, Thursday, August 13th, and Monday, August 17th also show glassy conditions with a clean surface. On the Wednesday and Thursday mornings, we see 3 ft from the west, with the period stretching to 9–10 seconds, which adds a touch more shape. The combined energy climbs into moderate territory – 128 and 177 respectively – meaning it has a little more push, but it’s still small. Then on Monday the 17th, there’s 4 ft swell from the northwest at 8 seconds coming in under a dead calm wind (143). These are your best bets overall, but even then, the wave quality is only described as “ordinary.” They’re not standouts by any stretch, just the least bad options.
Crowds are reported as “often” at Leca, so expect company, especially on those nicer mornings.
After the 17th, it really drops off. From the 18th through the 24th, the swell fades to almost nothing – mostly 1 ft to 2 ft – and the wind patterns are rubbish or the swell is tiny. There’s a brief, very small glassy moment on Sunday morning, August 23rd, with only 1 ft from the northwest at 9 seconds (52). That’s barely a ripple. It’s a long, flat end to the forecast period.
So, no true standouts. The pick of a very weak bunch is the glassy, clean mornings of August 12th, 13th, and 17th at Leca. If you’re desperate, grab a grovel board. Otherwise, save your energy.
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.
