The Lowdown
Alright, let's get into it. Rusty here, looking at what Bakio has in store for us over the next couple of weeks.
Right off the bat, Thursday the 10th is a write-off with messy, crummy conditions and not much energy in the water. We’ll see a bit of a pulse fade through Friday and Saturday mornings, giving us tiny, glassy waves on Friday morning and some clean knee-high dribble on Saturday morning if you’re desperate – nothing to write home about though. Then there’s a real dry spell from Saturday afternoon right through until the following Sunday morning. A gap of almost a week where the wind just ruins everything, blowing onshore or cross-shore and making a mess of things.
Now, Sunday the 13th morning is where it finally starts to look interesting. Bakio picks up a solid NW groundswell, with a long 13-second period pushing 4ft, and the combined energy reading is a solid 546. That’s a proper bump. The wind is glassy out of the SSW, so the waves will be clean. Expect some good, lined-up sets. Conditions hold up for Monday morning the 14th too: 4ft of NW swell at a long 12 seconds, glassy conditions, and an energy reading of 379. It’s a solid stretch of clean surf.
The mid-week gets messy again with strong cross-shore winds, so we sit through Tuesday to Friday with poor conditions. But then it cleans up nicely. Saturday the 19th morning sees a glassy dawn with 4ft of NW swell at 11 seconds and decent energy (287). Sunday the 20th morning is also glassy, 4ft of NW swell at 9 seconds, and the energy reading is 288.
But the real standout, and I mean the absolute highlight of this whole outlook, is Monday the 21st of September. This one is for the experienced crew only. We’re looking at a serious 8ft NW swell with a very long 14-second period, and the combined energy is a massive 2528 – that’s a lot of power. The wind is glassy out of the ESE. This is a proper groundswell, so at a beach break like Bakio it might break a bit straight and close out on the sets, but for experienced surfers on the right bank, it could be a session to remember.
It tapers off towards the end of the month, with Tuesday the 22nd still offering a solid 5ft NW swell (11 seconds) and glassy morning conditions. After that, it fades into small, ordinary waves for the final days.
Best bet: Sunday the 13th through Monday the 14th for the first good pulse, but the one to really circle is Monday the 21st of September – big, powerful, and clean, but for experts only.
Rusty.

Information about the Bakio Surf forecast
The above surf forecast table for Bakio provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bakio can be found by selecting the local surf guide option on the grey menu. Our Bakio 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 (Bakio) 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 Bakio 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.
Bakio is 7 km (4 miles) from Bermeo. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Bermeo. Bermeo has rooms for a wide range of budgets as well as car hire and transport links.
