The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for us over the next couple of weeks.

Right off the bat, we’ve got a bit of a slow start. The first couple of days are a write-off, with tiny, weak, and messy conditions. Nothing worth paddling out for just yet. Hang tight, because it’s the mornings that are going to be our saving grace.

The first real glimmer of hope shows up on Thursday, September 10th. The morning session is looking clean with a light cross-offshore breeze from the SW, and we’ll see some waist-high swell from the NW. The energy is picking up (270), and while it’s not a world-beater, it’s the first window where the stars align for a smooth, uncrowded paddle. The water is sitting at 73°, which is a touch warmer than usual for this time of year.

Honestly, that Thursday morning is the standout for the first week. The rest of the week is a mix of onshore wind and chop, or just too small to get excited about.

Now, looking further out, we have a real contender. On Wednesday, September 16th, the morning is looking like the pick of the entire forecast. We’ve got a clean, glassy start with a 5ft swell from the NW, and the energy is solid (508). That’s a proper long-period groundswell, and it’ll be pushing through with some real power. This is a setup for the experts, as it’s going to be a bit too big and punchy for beginners. The wind is off the land, so Mundaka should be offering up some of its best, most lined-up waves. Keep in mind, this is a week and a half out, so it’s promising but not set in stone. Crowds are likely at a spot this famous, so get there early.

The following weekend and into the next week, the size drops off. We get some glassy, clean mornings on the 17th, 18th, and 19th, but the swell is fading back to under 3ft. Those are great for a longboard or a funboard, but the magic of the 16th will be hard to beat.

So, if you’re picking a session, the Thursday the 10th morning is a solid bet for a clean, fun session. But the real standout, the one you want to circle on the calendar, is the morning of Wednesday, September 16th. That’s your best chance for some proper, powerful Mundaka waves.

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.
