The Lowdown
Alright, Rusty here. Let’s have a look at the 16-day window for Mundaka.
First thing you need to know – the next week and a half is pretty grim. The surf is small, weak, and the wind is all wrong. We’re looking at a real flat spell until the end of the month. From Saturday the 18th all the way through to Monday the 27th, the wave energy stays low, often under 100 (6 to 266), and the swell is tiny, mostly under 3 feet. The wind is blowing onshore or cross-onshore almost the whole time, chopping up what little bump there is. The water temperature is about average for the time of year, nothing unusual there.
The best chance of a wave comes right at the end of the run. Starting Tuesday the 28th, the swell picks up a bit. The standout is Wednesday morning, 29th July. We’ve got a 6 feet swell from the NNW, with a period of 11 seconds – that’s a proper groundswell, with some real energy behind it. The combined energy hits 634 (strong). The wind is light from the NE, just a cross-onshore breeze, so it won’t be glassy but it’ll be rideable. This is a heavy wave at Mundaka, a river mouth, and with that longer period it’ll line up nicely. But listen, this is an expert-only wave on a good day, and with 6 feet swell it’s pushing into the big range. It’s a consistent spot, so it’ll be breaking, but expect crowds to be often there. The swell direction is NNW, which is not quite the optimum NW, but it’s close enough to get the bank working. The water temp is still about average.
Before that, there’s a glimmer on Tuesday the 28th morning – 5 feet from the NW, period 9 seconds, energy 370 (moderate), with a light cross-onshore. It’s a marginal forecast, but it’s the best of the early stuff. Still, the wind is a bit off, and the period is shorter, so the waves won’t have the same punch as Wednesday.
The rest of the window after that drops off again. Thursday the 30th and Friday the 31st see the swell fading back under 3 feet, and the wind is back onshore. The first week of August looks flat and weak.
So, if you’re looking for a paddle, you’ve got to wait until the 29th of July. That Wednesday morning is the call, but it’s for experienced surfers only. The rest of the forecast is a write-off for good surf.
Rusty.

Information about the Mundaka Surf forecast
The above surf forecast table for Mundaka provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mundaka can be found by selecting the local surf guide option on the grey menu. Our Mundaka 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 (Mundaka) 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 Mundaka 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.
Mundaka is 2 km (1 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.
