The Lowdown

Alright, I’m looking at the 16-day window for Mundaka, and to be honest, it’s a pretty grim stretch for most of it. We’ve got a long, quiet run with only very brief moments where it might be worth paddling out. The best chance you’ll get is on Sunday, the 6th of September, but even that’s a one-session window.

The water temperature is about average for the time of year, so nothing wild there.

Let’s start with the first real glimmer. Tuesday the 1st has a little 4ft NW swell rolling in the morning, but with a cross-shore wind and marginal tide conditions, it’s not going to be anything special. The combined energy is moderate at 334, but the wind keeps it from being clean. That afternoon, the wind goes onshore and it’s poor.

Wednesday the 2nd morning is interesting – glassy conditions with a small 3ft NW swell, but the period is only 8 seconds and the energy is weak at 86. It’s surfable, but very ordinary. The rest of that week is mostly flat or tiny, with poor conditions, until we hit Saturday the 5th. That morning sees a 3ft NW swell with a 11-second period, which has some moderate energy (200), but the wind is light cross-shore and the rating is still poor. It’s just not coming together.

Now, Sunday the 6th of September is the standout. The morning session has a 4ft NW swell, with a nice 11-second period, and a light cross-offshore wind from the SE. The combined energy is moderate at 322 and the conditions are clean. This is the best you’ll see in the whole forecast. It’s a classic Mundaka setup – the river mouth, fairly exposed to the NW, and the direction is right on. But keep in mind, this spot is for experts only, and it’s often crowded. Expect company.

After that, it’s a long, dry spell. Monday the 7th gets a 4ft NW swell but the wind is a strong cross-shore, and it’s choppy. The rest of the week is tiny, with poor conditions and onshore winds. The middle of the month, from the 10th to the 16th, is almost all poor, with swell heights under 5ft and mostly cross-on or onshore wind. There’s a brief moment on Saturday the 12th morning with a clean cross-offshore wind and a tiny 2ft NW swell, but the energy is weak at 90 and the waves are very ordinary.

So, to sum it up: if you’re an expert looking for a clean session, aim for the morning of Sunday the 6th of September. Everything else is a write-off for the next couple of weeks. The breaks are inconsistent, and it looks like a long blank run for the area.

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.
