The Lowdown
Alright, surfers, let's talk about what's cooking for Leca over the next couple of weeks. It's Rusty here, and I gotta be straight with you – this forecast is a bit of a slow burn. We've got a long stretch of pretty ordinary conditions before things finally turn on.
Right now, we're looking at a week of frustrating conditions. From Tuesday the 8th right through to the middle of the following week, it's mostly a story of small, weak swell and messy wind. We get tiny waves around 1ft to 3ft but the wind is coming from the wrong direction, creating cross-onshore chop. The wave energy is low, ranging from around 53 to 205 for the most part. The water temp at Leca is sitting at 68°F which is about average for this time of year.
There's a tease on Saturday the 12th morning, with glassy conditions and a tiny 2ft swell from the WNW at 10 seconds, but it's just not got enough oomph to get excited about – combined energy is only 91. And that's pretty much it until next week.
Then, things finally start looking up on Sunday the 13th of September. That morning is the first real standout of the whole outlook. We've got a clean 3ft swell rolling in from the WNW with a nice long period of 12 seconds. The wind is a clean offshore from the East, and the wave energy is a solid moderate 315. This is the window to get your board wet – it ain't huge, but it'll be fun and clean.
After that, it gets messy again for the next week. We get a few more pulses of energy, like Wednesday the 16th, but the wind stays onshore and ruins it. The Friday the 18th has a clean cross-offshore wind, but the swell drops right off. There's also a 1ft glassy morning on Sunday the 20th, but it's just too small.
Now, hold onto your leash, because the real highlight is a long way off. On Wednesday the 23rd of September, a major pulse arrives. We're looking at a glassy morning with a 3ft swell from the WNW, but get this – that period is a massive 18 seconds! The wave energy is a very strong 514. That afternoon it builds to 4ft at 16 seconds with 767 energy. That's some serious, long-period groundswell. It'll be super clean thanks to the glassy wind, but with that long period, it could be a bit straight at the beach. That's a date to circle on your calendar, but it's a long way out, so keep an eye on the charts – it's promising but not locked in yet.
Overall, there's a massive gap of nothing worth paddling for until Sunday the 13th, and then another quiet spell until the big one on the 23rd. For the smaller days, with the poor quality and onshore wind, your kite might be more fun than your paddle. Keep your eyes glued for that last week of the forecast.
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.
