The Lowdown

Alright folks, Rusty here. Let’s get into it.

We’re looking at a pretty flat and quiet run ahead for the Basque Country. The first real surf we can talk about doesn’t show up until the morning of Saturday, the 15th of August, so there’s a solid gap of several days with nothing worth paddling out for. The overall pattern is weak, with tiny swell and poor conditions dominating the forecast.

That first real chance comes on Saturday the 15th in the morning. We’ve got a modest little bump of 3 ft from the northwest, but it’s a short-period affair at 6 seconds, so it’ll be weak and a bit lumpy. The wind is glassy, which is a small mercy, but the combined energy is only 111 (moderate wave energy), and the conditions are described as “surfable but very ordinary.” It’s not a standout, but it’s the first thing that’s actually rideable.

The next morning of note is Tuesday the 18th of August. Again, we’re looking at 2 ft from the northwest, but the period has bumped up to 9 seconds, which gives a little more shape. The wind is glassy, and the combined energy is 97 (weak), so it’s still not going to get the heart racing. It’s surfable, but very ordinary.

Then we get a slightly better window on Thursday the 20th of August in the morning. Swell is 3 ft from the northwest, period 9 seconds, with glassy conditions. Combined energy is 146 (moderate). This is about as good as it gets for the whole run, but again, it’s just “surfable with very ordinary conditions.” Not a standout by any stretch.

The best of the bunch, and the only thing I’d really call a highlight, comes on Saturday the 22nd of August. Both the morning and afternoon have glassy conditions, with a 4 ft northwest swell at 9 seconds. Combined energy is 187 (moderate) in the morning and 166 (moderate) in the afternoon. It’s still not big, but with glassy wind and a clean surface, the river mouth at Mundaka might offer a few fun ones. The swell direction is northwest, which matches the optimum swell direction for this spot. Just keep in mind this is a long-range call, so it’s promising but less certain.

Overall, nothing here is going to blow your mind. The water temperature is about average for this time of year, so no strange surprises there. If you’re desperate, the 22nd is your best bet, but don’t expect pumping Mundaka. This is a stretch for the patient crew.

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.
