The Lowdown
Hey, Rusty here. Let's talk about Bakio for the next sixteen days. The forecast window starts flat – nothing worth jumping in for from now through Wednesday, August 26th. Just a lot of nothing and crummy wind.
First real movement appears on Thursday morning, August 27th. Water temp is 76°F, about 5°F warmer than normal – feels like a bath. Swell is tiny, 3 ft from the WNW at 9 seconds, combined energy around 132 (weak). Wind is glassy, calm from the west at 3 mph. It's rideable but nothing to write home about.
Friday morning, August 28th, is the big one. Swell hits 6 ft from the NW, 10 seconds, with moderate energy (550). Light cross-off wind from the WSW at 6 mph – clean, lined-up waves. This is the call of the forecast. Saturday morning, August 29th, comes close: 6 ft NW, 10 seconds, energy 602, with a light offshore breeze from the south at 6 mph. Glassy, chest-to-head high sets. Note that 5–6 ft is on the stout side for a beginner spot – might test your skills. Crowds will be out, so set your alarm.
Sunday the 30th and Monday the 31st still give you clean smaller surf. Sunday morning: 4 ft NW with glassy east wind; Monday morning: 4 ft NW, dead calm, mirror-flat. Energies around 210–263, weak but fun for a log or a learner. Water stays warm.
From Tuesday, September 1st, the window closes. Swell drops under 3 ft, winds get messy, and by early September it's barely breaking. Not worth chasing.
Bottom line: the mornings of Friday the 28th and Saturday the 29th are your best shots – clean NW swell with good wind. Thursday the 27th is a maybe if you're itchy. That's 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.
