The Lowdown
Alright folks, Rusty here with the skinny on Leca in feet and degrees.
The next couple of weeks are a bit of a mixed bag, to be honest. We’ve got some swell on the way, but the wind is going to be a real pain for most of the run. There’s a promising little window right at the start, but it’s a grind until we get towards the end of the first week and into the second.
Right now, for Saturday the 29th and Sunday the 30th, we’re looking at small, weak chest-high waves around 4 ft from the WNW. The wind is a problem – it’s either onshore or cross-onshore, so the surf is pretty poor and choppy. Not much to get excited about. The combined energy is weak, sitting around 138 to 196 on the scale.
Monday the 31st sees the swell nudge up to 4 ft to 5 ft, and the combined energy jumps to moderate 241, peaking at 406 that afternoon. But again, the wind is cross or cross-onshore, and by the afternoon a fresh breeze is making it lumpy. The water temp is sitting at 65°F, which is about 1°F cooler than average for this time of year, so pretty normal.
Tuesday the 1st and Wednesday the 2nd of September are a write-off. The swell drops back under 3 ft, and the wind stays messy. Thursday morning the 3rd is a tease – we get a glassy morning with 3 ft from the NW, but the period is a short 7 seconds, so it’s surfable but pretty ordinary. Friday morning the 4th is the same story: glassy, 3 ft, but short period. The energy is weak at 85.
Now, Saturday the 5th of September is our first real standout. The morning brings a 5 ft swell from the NW with a much longer period of 12 seconds – that’s proper groundswell. The combined energy jumps to a strong 521! The wind is a light cross from the south, so it’s a bit side-shore but manageable. This is the best looking session of the first week. The longer period will mean better shape, but it can be a bit straight at the beach break, so keep an eye on the tide.
We then hit a dry spell from Sunday the 6th through to Wednesday the 9th. Swell drops to 2 ft to 3 ft, and the wind is back on it. A few mornings are glassy or clean, but the swell is too small to do much with.
Thursday the 10th of September is a weird one. The swell is tiny at 2 ft, but the period is a massive 15 seconds from the W. That’s very long-period groundswell, and the energy is moderate to strong at 323. It’s a cross-shore wind, so it’s side-shore. At this size, it’s a challenge, but if you’ve got a longboard, there might be a sneaky long ride.
Friday the 11th of September is the other standout. The morning sees a 5 ft swell from the WNW, with a 12-second period and a very strong combined energy of 683. That’s a lot of power. The wind is a light cross from the north, so it’s on the side. This is a big swell for the area, and at 5 ft, it’s pushing into intermediate territory. The quality is still marginal on the scorecard, but the energy is there.
Finally, that Sunday morning on the 13th of September looks like a big clean-up set. A 6 ft swell from the WNW with a 14-second period and a massive combined energy of 1623. The wind is a clean cross-offshore from the NNE. That’s going to be a powerful, clean swell, but at 6 ft, it’s definitely for experienced surfers only. The afternoon gets blown out again.
So, if you’re picking your days, Saturday the 5th of September morning and Friday the 11th of September morning are your best bets for the best balance of size and conditions. The Sunday the 13th morning is the biggest and cleanest, but it’s a big one.
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.
