The Lowdown
Alright, surfers, Rusty here. Let's have a look at what's on the menu for Bakio over the next couple of weeks.
To be straight with you, the immediate outlook is a bit of a slow cooker. We’re looking at a few days of weak, short-period energy with some pretty ordinary conditions. The water temperature is sitting at 75°, which is a solid 5° warmer than usual for this time of year – practically a bath, so you can leave the wetsuit at home if you're brave.
The first real glimpse of something decent comes on the morning of Thursday the 27th. It's not going to blow your mind, with a 2ft NW swell at 8 seconds, but that light offshore breeze from the SSE will clean things up. The combined energy is still weak at 63, so you’re looking at small, crumbly waves.
Things start to get interesting on Friday morning, the 28th. The swell pushes up to 5ft from the NW, with a period of 8 seconds. The wind is light offshore from the SSW, and the combined energy bumps up to a moderate 291. This is the first time the setup looks genuinely fun, with clean, punchy waves for the experienced crew. The afternoon will get chopped up by a NW cross-onshore, so make the most of the morning.
The stand-out session of the whole forecast, without a doubt, is Saturday morning, the 29th of August. Get up early. We’re looking at a solid 5ft of NW swell, and the wind is going to be dead glassy from the east. The water will be like a mirror. The combined energy sits at a nice 311. This is the pick of the run – clean, lined-up waves with a bit of power. It’s a classic Bakio morning.
The good news keeps coming for the first week of September. Tuesday morning, the 1st, is another glassy one with a 4ft NW swell. The wind is a light northerly, and the combined energy is 235. It’s a great option for a quieter session.
Looking further out to the second week, the outlook is a bit more mixed. The swell sticks around in the 4ft to 5ft range from the NW, but the wind starts to get a bit more fickle. The morning of Monday the 7th of September looks promising – a 5ft NW swell with a clean offshore from the WSW and combined energy of 354. It’s a promising call, but it’s a long way out, so keep an eye on it.
For the most part, the afternoon winds are a problem, making the surf choppy. The best bet is to keep your sessions to the mornings, especially when there’s an offshore or glassy wind. The 2nd of September morning has a 4ft NW swell with a longer 10-second period and a combined energy of 461, but the cross-shore wind will make it a bit jumbled. Still, that's some serious energy for the reefs.
So, the short version: Saturday morning the 29th is the absolute stand-out. If you’re looking for a clean, glassy session with a bit of size, that’s your window. The mornings around the 28th, 1st, and 7th are also solid runners. Don't waste your time on the afternoons unless you like wrestling with chop.
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.
