The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s comin’ our way.
Alright, straight up – this is a slow burn. The first few days are pretty ordinary, but there’s a real pulse of groundswell arriving later that’s got some serious potential. The standout is definitely Monday the 21st of September, but we’ve got some nice clean windows before that.
We kick off Thursday morning, the 10th, at Plentzia. It’s small, around 4ft from the NW with a 10 second period. The combined energy is weak (315), and it’s just surfable, nothing to write home about. The wind is light offshore from the ESE, so it’s clean, but there’s no power behind it. The afternoon sees the swell drop to 4ft and the wind swings cross-offshore from the NE, still clean but even less energy (243). It’s a session for the log, if anything.
Friday morning, the 11th, is glassy with the wind flat calm, but the swell has dropped right off to 2ft from the NW, period only 8 seconds and energy down to 83. It’s tiny. Afternoon’s the same size but with a cross-offshore breeze, still clean but small.
Saturday the 12th is a write-off. The swell is down to 2ft and 1ft, energy is in the 40s, and the wind is okay but the waves are just not there. Poor surf.
Now, here’s where it gets interesting. Sunday the 13th, we see a proper groundswell pulse. The morning has 4ft from the NW, but the period jumps to 13 seconds, and the energy hits moderate (546). The wind is a light cross-offshore from the S, so it’s clean. The afternoon is even better: 5ft, 12 seconds, and energy up to 602. This is clean, lined-up, and has some real push. Plentzia is a sheltered spot, so this longer period groundswell should wrap in nicely. This is the first real taste of the good stuff.
Monday the 14th is still solid, with 4ft in the morning, 12-second period, and clean offshore ESE wind (379). The afternoon drops a touch to 4ft, but still clean. Solid, consistent surf.
Tuesday the 15th is a bust. The wind goes onshore from the WNW, the swell is small and messy, and by the afternoon we’ve got 6ft but with a horrible 6-second period and onshore wind at 15 mph. It’s a mess. Wednesday and Thursday the 16th and 17th are straight-up blown out, with strong onshore winds and building swell. The energy is high (473-533), but it’s all wind chop. This is kite-surfing weather, not paddle surfing.
Friday the 18th and Saturday the 19th are still poor, with weak, onshore wind and small, messy waves. We get a bit of glass again on Saturday morning with 4ft, but it’s just ordinary.
Now, here’s the real standout. Sunday the 20th of September. The afternoon sees a monster pulse: 4ft from the NW, but with an incredible 18-second period. The combined energy is a massive 1233 – that’s strong groundswell. The wind is clean cross-offshore from the NE. This is a special, special window. That long period will make for some beautiful, long walls at Plentzia, but it’s also a very long period, so expect the sets to be a bit more spread out. It’ll be worth the wait.
But the absolute best on offer is Monday the 21st of September. The morning is solid 8ft from the NW, 14-second period, with offshore ESE wind at only 3 mph. The energy is a huge 2528. This is excellent surf, but at 8ft, it’s for experienced surfers only. It’s clean, powerful, and consistent. The afternoon is still pumping at 8ft with 13-second period and cross-offshore wind. This is the best session of the forecast, no question.
Tuesday the 22nd is still good, with 5ft in the morning, glassy conditions, and 11-second period (544 energy). A solid leftover swell with clean conditions. Wednesday the 23rd drops right off, and the rest of the forecast into late September is small and weak, back to tiny 1ft to 3ft waves with no real energy.
So, overall: the first few days are small and average. The real action kicks off Sunday the 13th with a nice clean groundswell, but the absolute standouts are Sunday the 20th afternoon and Monday the 21st. That Monday is the big one – big swell, long period, and offshore wind. It’s a day for the experienced crew only.
Stay frothy, catch you out there.

Information about the Plentzia Surf forecast
The above surf forecast table for Plentzia provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Plentzia can be found by selecting the local surf guide option on the grey menu. Our Plentzia 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 (Plentzia) 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 Plentzia 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.
Plentzia is 8 km (5 miles) from the city of Getxo. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Getxo. Getxo has rooms for a wide range of budgets as well as car hire and transport links.
