The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming down the line for Bakio.
Okay, so the next couple of days are pretty flat and messy. Honestly, nothing to get excited about. Saturday the 12th is a write-off with weak, short-period leftovers and not a breath of decent wind. You’re looking at a bit of a drought until Sunday morning.
Sunday the 13th is where things start to wake up. That morning, the wind goes glassy out of the ESE, and we’ve got a proper groundswell filling in from the NW at 4ft. The period is a solid 13 seconds, and the combined energy is moderate at 546. That’s a good sign. The water temp is about average for this time of year. Bakio is an exposed beach setup, so that long period swell – anything over 11 seconds really gets it going. Expect clean, lined-up waves. The offshore wind will have it looking pretty. Crowds are possible here. This is one of the better windows in the whole run.
The surf hangs in there through Monday and Tuesday the 14th and 15th, but winds turn cross-shore and then onshore, chopping things up. Not worth paddling out unless you’re desperate.
We get another chance on Friday the 18th. The morning starts off clean with a light SW cross-offshore breeze and a 3ft NW swell on a 10-second period. Combined energy is moderate at 282. It’s small but clean, a good one for the logs.
Now, hold onto your board. The real standout is a week and a half out, on Friday, the 25th of September. The morning is looking absolutely pumping. We’ve got a 8ft NW groundswell with a 14-second period – that’s very long period. The combined energy is massive at 2397, so that’s strong. The wind is glassy and offshore from the SE. This is expert territory. That size and that power at a beach break like Bakio... the long period will make it wall up, but it might break a bit straight. It is going to be powerful, clean, and for experienced surfers only. This is the one to circle on the calendar. Crowds will be inevitable.
The following Sunday the 27th cleans back up with a glassy morning and a 3ft NNW groundswell at a very long 15-second period. Combined energy 560. A nice little clean-up set to finish the run.
So bottom line: the first few days are a bust. Sunday the 13th is your early call for clean, fun waves. But the big dog is definitely Friday the 25th – that’s the one for the crew who can handle it.
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.
