The Lowdown

Alright, let’s break down this stretch at the rivermouth. The first few days are a bit of a letdown—nothing’s clean, and the swell’s weak. Thursday the 10th is a write-off with bumpy, cross-onshore junk, and Friday and Saturday are just too small. You’re looking at waist-high dribble with a few clean windows but zero power. Not worth paddling out.

But things finally click into gear on Sunday the 13th. Morning’s glassy, and there’s a solid 4ft of NW groundswell moving in—the energy jumps, and the period stretches out to 13 seconds. This is the kind of swell that makes the point start rifling. Monday the 14th is even better—still glassy, 4ft on a 12-second period. Those mornings are proper, well-shaped, and offshore enough to keep them clean. The afternoons both days turn to junk when the sea breeze kicks in.

Now, from Tuesday the 15th to the 20th, it’s a wild mess. The wind goes crazy, and we’ve even got a thunderstorm risk. The swell is up there, but it’s lumpy and crossed-up—just a battle, not a pleasure. You can have it.

The real gem in this window is Monday the 21st of September. The forecast for Monday morning is absurd. We’re talking about a solid 8ft of NW swell with a 14-second period. That’s a serious, powerful groundswell. The energy reading is huge (2528), and the wind is dead flat—glassy as a lake. That’s the day for the experts, a truly heavy, clean, world-class session at Mundaka. It’s well over 2.5m, so it’s too big for most, but for those who know the place, that’s the day you talk about for years.

The morning before, on Saturday the 20th, is a decent, smaller 4ft, glassy warm-up. And the Tuesday after the big one still has some fun 5ft sets early on. But by Wednesday and Thursday, it’s gone, fading to small and weak.

The water’s about average for this time of year. Early on, you don’t need much of a wetsuit. But for the first several days, the surf’s simply not worth the drive. That Monday the 21st, though—that’s the pulse. It’s nearly two weeks out, so don’t bet the farm on it, but if that glassy morning wind holds, it will be all-time and packed. That’s the one to chase.

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.
