The Lowdown
Alright, Rusty here. Let’s chew the fat on what’s coming up for Bakio over the next couple of weeks.
Honestly, the first few days are a bit of a bummer. Tuesday the 18th and Wednesday the 19th are flat and messy, with tiny 1ft to 2ft waves and short period swells. You’re better off kicking back on the sand.
The first real chance you get is the morning of Thursday the 20th. The swell picks up to 4ft from the NW with a long 11-second period, giving a moderate combined energy of 263. The wind is light and cross-shore, but it’s only marginal. It’s a start.
Friday the 21st morning is the first true highlight. We’ve got a 5ft NW swell with a clean cross-offshore wind from the WSW. The energy is moderate at 432. The afternoon gets choppy, so the morning is your window.
Then it goes quiet again. Saturday the 22nd and Sunday the 23rd drop off, and the rest of the week is nothing special – small, bumpy, and weak.
The big one, and I mean the one to mark on your calendar, is the morning of Tuesday the 1st of September. The swell hits 5ft from the NW with a long 11-second period, and the combined energy is a strong 606. The wind is clean offshore from the SSW. It’s a long way out, but it’s the best we’ve got.
Wednesday the 2nd of September morning is also a good shout. Another 5ft NW swell, this time with a 12-second period, giving a very strong energy read of 747. Again, offshore wind keeps it clean, but the afternoon could get messy.
The water temp is a warm 76°F, which is much warmer than usual for this time of year – a real bonus.
The 5ft-plus swells are for intermediate and above, but the 4ft days are fine for beginners if the wind plays ball. The key is the clean offshore wind – that’s when Bakio shines.
Stay keen, and I’ll see you out there.

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.
