The Lowdown

Alright, let’s get into it. This is Rusty, and I’m looking at the next couple of weeks here at Mundaka. Honestly, it’s a bit of a mixed bag, and you’ll need to be patient. The first proper chance of anything decent isn’t until the 10th of September, so there’s a bit of a dry spell to sit through.

Right now, into the weekend, forget it. We’ve got a weak, jumbled sea with a lot of cross-shore wind. The energy is just not there, and the conditions are messy. You’d be wasting your time paddling out. That continues through the start of the week, with the swell dropping off and the wind playing games. It’s a real nothing period.

The standout window, and the only real one to get excited about, is the morning of Thursday, the 10th of September. That’s when the stars align briefly. We’ve got a clean 5ft northwest groundswell rolling in, with a period of 11 seconds. The wind is glassy, dead calm, which is a major win for a spot like this. The wave energy is moderate (476), and the swell direction is straight out of the northwest, which is exactly what this river mouth wants. The tide will be a factor, but if you get the push right, Mundaka will be offering up some of those long, bowling lefts. This is expert territory at the best of times, and with that 5ft of clean NW swell, it’s going to be a proper session for the crew who know what they’re doing. It’s the best on offer, no question.

After that, it’s back to the waiting game. The wind swings onshore again, and the swell gets thrown around by strong northerly breezes. There’s a bit of a long-period pulse (16 seconds) on the 15th, but it’s blown out by a fresh 15-18 mph cross-onshore wind, making it a lumpy, choppy mess. That’s not a paddle session; that’s more for the kite crew if anything.

Even into the final week of the forecast, the 18th and 19th of September, you get a little bit of clean glass again, but the swell is tiny, just 2ft. It’s surfable, but very ordinary. Not worth the hype.

So, bottom line: save your energy for the 10th of September morning. That’s the one. The rest of the run is a lot of waiting, with a lot of poor conditions. Keep an eye on it, but don’t hold your breath.

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.
