The Lowdown
Alright, this is Rusty. Let’s talk about Mundaka.
Look, I’ll be straight with you – the next week and a half is a bit of a heartbreaker for this legendary river-mouth wave. The water is sitting at 75° with a 5° anomaly, so it’s much warmer than usual for this time of year, which is a nice touch. But the surf? Honestly, most of the time it’s just poor. There’s a big gap of small, weak, and messy conditions stretching from the start of the forecast right through the first week. You’ll see a few glassy mornings with tiny 1ft to 2ft waves, but the energy is pathetic – we’re talking combined energy readings of 25, 36, 75 – nothing that’ll get you excited. The swell direction is mostly WNW or NNW, which isn’t the optimum NW for the spot, and the periods are short, under 10 seconds. It’s not worth paddling out.
Even on Thursday the 6th, when the swell bumps up to 4ft with a combined energy of 264 (moderate), the wind is a cross-onshore mess and the conditions are poor. That’s a write-off. The same goes for Sunday the 9th: a glassy morning with 2ft NW swell at 10 seconds and energy of 102 – the rally call says “surfable but very ordinary”. It’s not a standout.
The real story, the one that has my heart racing a little, is the Monday morning of the 17th of August. The swell jumps to 7ft from the NW, with a period of 9 seconds and a combined energy of 628 – that’s strong, meaty energy. The wind is glassy, offshore, from the north at only 3 mph. This is the one. For expert surfers only – 7ft is too big for beginners. The direction is NW, which is exactly what Mundaka wants. It’s going to be a long, clean, powerful left-hander. Expect it to be crowded though, because this spot “often” gets busy, and with a swell like that, everyone will be calling in sick. It’s a standout, but keep in mind it’s a long-range call, so the details could shift.
The Monday afternoon of the 17th still has 7ft of NW swell, but the wind swings east and goes cross-shore, making for a more marginal, choppy look. Tuesday the 18th is a washout with strong winds from the WSW and rain showers, dropping the quality fast.
So, to sum it up: the first week is a flop. The 17th of August is the only true gem on the table, and it’s a beast. If you’re an expert and you can wait, that’s your window.

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.
