The Lowdown
Alright, grab your wettie, check your leash, 'cause we're lookin' at a long and lean stretch here at Plentzia. Honestly, this is one of those outlooks where patience is gonna be the name of the game. The next two weeks are mostly a write-off for anything you'd call a proper session. There's a solid week-plus gap of nothing but fluff and poor conditions before we get a real glimmer of hope right at the very end.
Right now and for most of this week and the next, the swell is tiny—we're talking 2 ft to maybe just over 3 ft—with weak, short-period windswell. The energy just isn't there, and when there is a little bump, the wind usually has its grubby mitts all over it. For the next several days, you’re looking at cross-on breezes, choppy surfaces, and that frustrating lack of push. It's basically a flat spell. The only real standout of the whole run comes much later.
Things start to stir on Thursday the 20th of August, but don't get excited yet. That afternoon sees the swell jump to 5 ft from the NNW with a 12-second period, giving us a solid energy reading of (509), but it's hammered by a crisp, 15 km/h cross-on wind from the NNW. It's going to be a choppy, messy mess.
Friday the 21st of August morning is still marginal, but keep an eye on the afternoon. We get a clean 5 ft swell from the NW (period 10 seconds) and the wind goes glass. That's a proper window—clean faces and some push. A score of 2 out of 10 here feels like a win considering the rest of it. It's a classic, short-lived call.
There’s another blip on Sunday the 30th of August. The morning looks promising: 6 ft of NW swell (10-second period, energy (510)) with a light cross-off from the SSE. The wind is just a slight air, so the surf should be clean. But by the afternoon, the wind swings onshore and it's game over.
After that, we roll right into September with onshore winds and a bumpy sea state. The water's sitting about average for the time of year, so no surprises there.
Alright, listen. If you had to pick a moment, it’s Friday 21st August afternoon at Plentzia. That glassy window with a clean 5 ft NW swell is the only real, clean opportunity in the whole sixteen days. It’s a rare treat in an otherwise barren forecast. The surf direction (NW) isn't the absolute optimum for this break (which prefers WNW), but the clean conditions and solid 5 ft waves make it the best on offer. Just don't expect a crowd-free zone; it's likely to get attention.
Other than that, this spot is a desert until the very end. It's a rare blank run, but for a sheltered spot like Plentzia, it happens.

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.
