The Lowdown

Alright, let’s get into it. Leca’s got a bit of a slow start here, but there are a few windows worth paddling out for.

First up, the early part of the outlook is pretty quiet. Friday the 11th is a write-off – small, messy, and the wind’s all wrong. The first real glimmer comes Saturday morning the 12th: tiny 0.5ft from the west with a light offshore breeze out of the east. It’s small and ordinary, but clean enough for a beginner to get a few soft ones. Not much to write home about.

Sunday the 13th morning is where it starts getting interesting. Swell bumps up to 3ft from the west-northwest, period stretching to 12 seconds – that’s groundswell energy starting to push through. Winds are light and cross-off from the east-southeast, so the surface is nice and clean. Combined energy sits at 273 (moderate). For Leca, that’s decent – better shaped waves with a bit more punch. The afternoon gets chopped out by a cross-on breeze, so get in early.

Monday the 14th morning is okay – 2ft, clean, but nothing special. The real standout stretch kicks in mid-week. Thursday the 17th morning: 4ft from the northwest, 10-second period, light northeast cross-off breeze, clean conditions, and combined energy at 355 (solid moderate). That’s the first proper session of the window.

But the real gem is Friday the 18th morning. Glassy. Dead calm wind from the south-southwest, 4ft from the northwest, 9-second period, combined energy at 240. The wave comment says expect good conditions, and I’m feeling it. That’s clean, fun-size surf with no bumps. Get on it.

Saturday the 19th morning is another glassy morning – 3ft from the west-northwest, 11-second period, combined energy 227. Clean again, though smaller.

Then we’ve got a long-range standout that’s worth marking on your calendar. Sunday the 20th morning is glassy again, with a 3ft swell but look at that period – 16 seconds, very long groundswell, and combined energy at 476 (strong). That’s a lot of grunt for a small wave. For a reef or point, that’d be magic; at Leca, being exposed to the west-northwest, it might be a bit too straight for the beach, but still clean and with proper push.

Monday the 21st morning: 5ft from the northwest, 13-second period, light offshore from the east-northeast, clean. Combined energy at 757 (very strong). That’s the biggest, best-shaped swell of the run, and the wind is your friend. This is the top pick for experienced surfers – it’s solid and lined up. The afternoon will get messy with cross-on wind, so it’s a morning mission.

Tuesday the 22nd morning is very similar: 5ft from the northwest, 13-second period, gentle offshore from the east, combined energy 761. Another morning of good, clean northwest groundswell. The swell direction matches the optimum for Leca (west), so expect it to wrap in nicely.

From there, it fades. Wednesday the 23rd morning is still clean with 4ft from the northwest, but the energy drops to 229. Thursday the 24th is flat and glassy but only 3ft with short period – barely worth it. The end of the run on the 25th and 26th is messy or marginal.

For the whole window, the standout sessions are Sunday the 13th morning for a clean, fun little session, and the big one: Monday the 21st morning – 5ft northwest groundswell, offshore wind, very strong energy – that’s the pick of the lot. If you’re a beginner, stick to the clean, smaller mornings like the 12th or 19th. The 21st is pushing into expert territory at over 5ft, but not too big.

Water temp is running about average for this time of year at Leca – no major anomaly to report.

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.
