Table - best surf conditions forecast for Bakio over the next 16 days.
The Lowdown
Right, let’s talk feet and Fahrenheit.
First decent window at Bakio is Thursday morning the 28th. Clean cross-off wind, chest-high waves around 5ft out of the NW, period short at 8 seconds – that’s windswell energy. Water temp’s 75°, which is 5° warmer than normal for late August. That’s notable – really warm. Combined energy sits at 298 – moderate.
Friday 29th morning goes glassy, S wind, 5ft NW swell, period up to 9 seconds, energy jumps to 397. Clean.
Saturday 30th August – that’s your first standout. Glassy, dead calm wind. Waves 5ft from the NW, period 10 seconds, combined energy 433. That’s a solid, clean session. Not huge but quality. Crowds often, so get in early.
Then it flatlines from Sunday 31st through Thursday 4th September. Knee-high junk, onshore winds, combined energy falling to double digits. That’s five days of nothing.
Don’t sleep on Saturday 5th September though – that’s the big one, but it’s over a week away so treat it like a rumor right now. Glassy offshore-SW breeze, swell 6ft from NW, period stretching to 13 seconds – proper groundswell. Combined energy rockets to 1002 – strong. That’s expert territory, maybe a bit big for beginners. The long period might make the beachie a little straight, but with zero wind, it’ll be memorable.
After that, it’s all downhill. Weak waist-high dribble for the rest of the run. Tuesday 8th morning shows glass but only 2ft – session for the hardcore. 12th September is a 1ft ghost swell at 16-plus seconds – just ocean breathing.
So, mark your calendar for August 30th and *maybe* September 5th. Everything else is a skip.
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.
