The Lowdown
Alright folks, Rusty here. Let’s get into it.
Right off the bat, I gotta be honest with you – the next week and a half is a bit of a grind. The swell is small and the wind is messy. We’ve got to wait until Sunday the 13th of September for the real deal.
For the first few days, starting Thursday the 3rd, we’re looking at tiny surf. Thursday morning has a weak 2ft swell from the NW with a short period of 8 seconds and a cross-onshore wind, so it’s choppy and pretty poor. The combined energy is weak (53). Friday the 4th is a near washout – the swell is still tiny (2ft) and the wind is onshore or cross. Saturday the 5th shows a little pulse, with the swell picking up to 3ft, but the period jumps to 11 seconds which is a bit better. The wind is cross-shore and the wave energy is moderate (281), but it’s still a marginal call. Sunday and Monday are similar – small, cross-shore winds, nothing to get excited about.
We then hit a real dry spell from Monday the 7th through to Saturday the 12th. The swell drops, the wind is mostly onshore or cross-onshore, and the energy is low. There’s a brief moment on Wednesday morning the 9th – the wind goes glassy, and the swell is 4ft, but the period is a short 8 seconds, and the energy is only moderate (176). It’s surfable, but it’s very ordinary. Honestly, this stretch is a write-off for a proper paddle.
Now, the standout. The real action is locked in for Sunday morning, the 13th of September. This is the one to circle. The swell jumps to 6ft from the NNW with a long period of 14 seconds – that’s proper groundswell energy. The combined energy is a strong 1020, so there’s plenty of power. The wind is glassy, zero, dead calm. The forecast says excellent surf conditions for experienced surfers. At 6ft, this is a solid size, so it’s best for those with some experience, not for learners. The long period (14 seconds) will mean long lines and good shape, but it’s an exposed beach break, so expect it to be a bit thumping and straight. This is your best window of the whole outlook.
The week after that has some cleaner windows. Monday the 14th morning has a 4ft swell from the NW with a period of 11 seconds and glassy conditions. The energy is moderate (297) – it’s a good, clean option, but not as powerful as the Sunday. Tuesday the 15th is smaller, and Wednesday the 16th morning has a small 3ft swell with a light cross-offshore wind, making for clean conditions. Thursday the 17th and Friday the 18th are back to small, choppy, and poor.
So to sum it up: you’ve got a long wait through a flat, windy week. The big day is Sunday the 13th of September – that’s your best bet for a proper session. After that, Monday the 14th and Wednesday the 16th have some clean, smaller windows. The rest is just a waiting game.
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.
