The Lowdown

Alright folks, Rusty here. We’ve got a look at the Bakio region coming up, and it’s a bit of a slow burner to start. The water is sitting at 72° right now, which is much warmer than normal for this time of year, so that’s a nice little bonus.

The first few days are grim. Wednesday the 16th and Thursday the 17th are total write-offs with poor surf conditions and onshore winds making a mess of things. The swell coming in is a weak to moderate 256 combined energy, jumping up to 595 by Thursday morning, but the wind just kills it. You can leave the board in the car.

Friday the 18th morning shows some life. We’ve got a clean 4ft swell from the NW (9 seconds) with light cross-offshore breezes. The combined energy is 287, still weak, but it’s clean. Not a standout, but the first real sign of hope. The afternoon jumps up to 7ft with a very strong 1799 combined energy, but that onshore wind makes it a messy proposition.

Saturday the 19th is a frustrating one. The morning has a cleanish 7ft NW swell (13 seconds) and light cross winds, but the combined energy is a strong 1380. The rating is there, but it’s not quite firing on all cylinders. The afternoon flips to onshore again.

Now, here’s the highlight of the outlook. Mark your calendars for the morning of Sunday, September 20th. That’s the best of the bunch. Glassy conditions, zero wind, and a solid 5ft NW swell with an 11-second period. The combined energy is a moderate 576. The wind is calm, so it’ll be clean and lined up. This is the one to aim for. The crowd profile at Bakio often has people, so don’t expect to have it to yourself, but the conditions will be worth sharing.

Monday the 21st morning is also glassy with a similar 5ft NW swell (12 seconds) and 559 combined energy. Another excellent morning if you can sneak out.

Tuesday the 22nd offers another glassy morning, but the swell dips to 4ft. It’s clean, but smaller.

The next real standout is Wednesday morning, September 23rd. This one is for the experienced crew. We get a clean, 5ft NW swell with a very long 15-second period and a strong 1017 combined energy. The light offshore wind will groom it beautifully. This is a groundswell, and at 15 seconds, it’ll have plenty of punch, but it might ask a bit more of you at a beach break. For the better surfers, this is a proper session.

From there, the surf drops off through the end of the month. The morning of Saturday the 26th has a 4ft NW swell (15 seconds) and 738 combined energy, but it’s cross-shore winds. Not terrible, but not a standout.

By the end of the period, around the 30th of September and the 1st of October, we see a big pulse of swell – 8ft to 10ft – but it’s all onshore and messy. Total write-off for paddling, might be more interesting for the kite crew if you’re into that.

To sum it up: If you can get out Sunday the 20th or Monday the 21st in the morning, that’s your best bet for clean, fun waves. For the more experienced crew, Wednesday the 23rd morning is the bigger, more powerful session. The rest of the window is a mix of small clean days and blown-out swells.

Rusty out.

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.
