The Lowdown
Right, let’s break it down in feet, ‘cause that’s how some of you measure.
At Bakio, it starts flat and poor. Thursday 27 August is a total dud: 1ft to 2ft, choppy, no go. The first real chance comes Friday 28 August morning with a clean 4ft swell from the WNW, period around 7 seconds, light cross-off wind from the SW. Small, but clean and rideable.
The standout window is Saturday 29 August morning. Glassy flat calm, 6ft of NW swell, 9-second period. Smooth, offshore, and the break is exposed to that direction. Combined energy is 470 – solid moderate juice. That’s too big for total beginners but prime for intermediates. Afternoon gets a bit bumpy and drops to 5ft – still okay but not as nice.
Sunday 30 August morning is another good shout: glassy, 4ft NW swell, 8-second period, energy 360. Clean and fun. Afternoon turns choppy with a cross-on breeze.
From Monday 31 August into early September, things go average: 4ft to 5ft waves but with cross-on winds and marginal conditions. Not terrible, not great.
There’s a dry spell from Wednesday 2 September to Friday 4 September – waves under 3ft and mostly poor. Not worth the effort.
Mark Saturday 5 September: morning brings 4ft NW swell with a long 11-second period – groundswell, energy 420, cross winds. By afternoon, it jumps to 5ft with a 13-second period and energy 878 – strong power. Wind is cross-on though, so it’s not perfect. That’s expert territory as it pushes toward 8ft.
Sunday 6 September holds 5ft NW swell, 11-second period, energy over 600 – again with cross-on breezes. Big and powerful, but not clean.
Water temp is 75°F, which is about 5°F warmer than normal for this time of year – a notable anomaly, so you’ll be comfy in a spring suit.
Best call: Saturday 29 August morning, glassy, 6ft, clean. If that slips, Sunday 30 August morning is your backup. For the big-wave crew, Saturday 5 September holds serious power, just mind the cross-on wind and expect company – Bakio gets busy when it’s good.

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.
