The Lowdown
Alright, grab your board and wax, I'll give you the rundown for Plentzia over the next couple of weeks.
First thing’s first, the water’s running a touch warmer than normal for this time of year, sitting at 73°, about 4° above what you’d expect. That’s a nice little bonus, but the surf itself? It’s a mixed bag with a long, quiet spell coming up. The next few days are pretty ordinary, with a bit of a swell due to show early next week, but the real standout is shaping up for the second week.
We kick off on Monday the 31st of August with a bit of a windswell from the NW, coming in at around 6 ft. The combined swell energy is moderate, sitting at 639, but the wind is a cross-onshore breeze, so it’s choppy and not really worth getting excited about – a poor session in the making.
The first three days of September are flat and grim. Tuesday the 1st has a glassy morning with 4 ft NW swell (energy 334), but the sets are weak and it’s just ordinary, small stuff. Wednesday and Thursday drop off even more, with swell barely hitting 2 ft. We’re basically looking at a complete lull from the 2nd through to the 4th of September. You could skip those days without missing a thing.
Friday the 5th of September sees a bit of life come back. The Saturday morning (5th) brings a clean offshore wind from the E and a 3 ft NW groundswell with a decent 12-second period. The energy jumps to 359, but the size is still marginal – it’s a surfable wave, but nothing special. Saturday afternoon picks up to 5 ft with a 13-second period, energy hitting 792, making it a moderate to strong push. The wind is cross-offshore, so it’s clean, but the forecast notes marginal tide conditions, so you’ll have to pick your moment.
Sunday the 6th of September is the pick of the first week. A lovely glassy morning with a 4 ft NW groundswell (12-second period) and a combined energy of 448. The conditions are solid, clean, and glassy – this is the session you want to aim for. But just a heads-up, the afternoon switches onshore and goes bad.
Then from Monday the 7th through to Thursday the 10th, we’re back to small and poor surf. It’s a real slog with most days offering less than 3 ft and messy winds. The energy drops into the double digits much of the time.
Friday the 11th of September shows a slight uptick, with a glassy morning and 5 ft NW swell (307 energy). Still ordinary, but at least it’s not flat. Saturday the 12th is similar – glassy morning, 4 ft, very average.
The real standout is the morning of Tuesday the 15th of September. This is the one to circle. A solid 5 ft NW swell rolls in with a very long 13-second period, pumping combined energy of 810. The wind is glassy – dead calm – which will make for absolutely perfect, clean conditions. With that long period, the waves will have proper shape and power, and the gaps between sets will make paddle-outs that much easier. This is expert territory though; with 5 ft and that period, it’ll be powerful and not for beginners. Plentzia is a sheltered spot and prefers WNW swell, but this NW swell will still deliver.
The best bet by far is the morning of Tuesday the 15th. Glassy, solid swell, and very long period – that’s the one to get excited about.

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.
