The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for Leca over the next couple of weeks.
Honestly, the first week and a half is pretty grim. We’re looking at a long stretch of poor conditions starting from Monday the 24th of August, with onshore winds and messy surf. It’s not until Friday the 28th of August that we get a real window of opportunity, and that's really the standout.
That Friday morning is it. For a few hours, the wind swings to a light offshore from the northeast, the sky is clear, and the swell is a solid 6 ft from the west with a 10-second period. That’s clean. The combined wave energy is pretty decent too. The water is a bit colder than normal for this time of year at 64°, so you’ll want a decent spring suit. If you can get out, it looks like the best we’re going to see for a while.
After that, it’s a bit of a mixed bag with onshore winds creeping back in. There’s a promising blip on the 6th of September, a Sunday morning, with a glassy 4 ft swell from the west-northwest at 11 seconds. It’s a long way out, but if the forecasts hold, that’s another one to mark in your calendar.
Right at the very end of the outlook, we’ve got potential groundswell moving in. The 8th of September, a Tuesday, early morning shows a 8 ft swell from the west-northwest with a 14-second period. That’s a lot of power. That is big, long-period groundswell. At this size, it’s one for experienced surfers only at a beach break like Leca, as it might close out, although the light cross-shore wind in the morning could keep it tidy. But, with a 16-day lead time, treat that as a promising possibility, not a certainty.
So, the plan is: wait for Friday 28th morning, and keep an eye on the 6th and 8th of September. It's not a great run overall, but there are a couple of proper windows in there.
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.
