The Lowdown
Alright, let me tell you how things are shaping up here. This stretch of coast is a bit of a mixed bag. We’re looking at Plentzia, and frankly, the next week and a half is a bit of a slow-burner. The water is 75.2°F, which is much warmer than usual for this time of year, so it’ll feel nice when you get in, but the waves need a bit of patience.
We start off with some swell Friday morning, a 5.2ft NW groundswell (10 second period), but that heavy WNW wind at 16 mph is just ruining it – messy onshore chop. That energy reading of 518 is moderate, but it’s not surfable. Friday afternoon is the same story with a bigger swell. We don’t see any real opportunity until Saturday morning the 22nd. That’s a 3.6ft NW swell with a clean offshore easterly breeze at 9 mph. The energy drops to 203, but the wind is good, and it’ll be glassy. Still, it’s only a small wave, not a standout.
There’s a long gap after that. The days roll by with tiny, weak swell – often under 1.5ft – and poor conditions. The energy readings are all below 100. This area isn’t known for delivering when it's flat, and this is one of those spells. We’re looking at over four days of very little to no real surf.
Things start looking up towards the end of the month. Friday morning the 28th has a more solid 7.9ft NW swell (9 seconds), giving us a strong 926 energy reading. The wind is a light cross-onshore from the SW at only 3 mph, so it’s nearly glassy. It’s a bit of a lumpy swell, and with that size it’s getting into intermediate territory, not for beginners. But the combined energy is strong, and it’s the best wave of the first week.
The real standout, the one to circle on your calendar, is Saturday morning the 29th. We get a clean 5.2ft NW swell (10 seconds) with a light, cross-offshore breeze from the SE at 6 mph. The energy is a solid 489, and conditions are clean. It’s not a giant day, but the quality is there. It’s the best balance of size and clean conditions in the whole outlook.
After that, we drift again. Sunday the 30th has a glassy 4.3ft wave, but it drops off. Going into the first week of September, there’s more energy on Thursday the 3rd with a 5.9ft NW swell from a 12-second period – that’s a long period groundswell, giving a strong 1025 energy reading. But it’s cross-onshore and chopped up. And again, the afternoon gets hammered by a fresh 19 mph onshore wind.
Finally, for those looking way ahead, Saturday morning the 5th of September offers another promising looking window. A 7.2ft NW swell (9 seconds) with glassy conditions and a 732 energy reading. It's a big wave for the area, so only for those with experience. But it’s still a long way out, so don’t bank on it yet.
Bottom line: This is a period of waiting for the right window. Saturday the 29th is your best bet for a clean, fun session. Don’t expect much else for the rest of the fortnight.

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.
