The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking in the water.
Right off the bat, we’ve got a solid window of surf coming up, but it’s not a straight run of perfection. The best of the bunch is sitting right there on Monday the 27th of July. We’re looking at a clean, glassy morning with a 5ft NW swell rolling in at a nice 10-second period. The energy is solid, with a combined total of 540 (moderate to strong), and that north-west direction is exactly what Mundaka wants to see. This is a classic setup for the river mouth, and with the glassy conditions, it’s going to be a real treat. The water temp is about average for the time of year, nothing wild.
Monday afternoon, the wind swings around to a cross-on NE breeze at 9 mph, and the quality drops off a cliff. The swell backs off a touch to 5ft, but the wind chop makes it messy. Not worth it.
Tuesday the 28th starts clean again. The morning has a cross-off E wind at 9 mph, with 4ft of NNW swell and a 10-second period. The energy is still decent (340), and it’ll be a much cleaner, more lined-up wave than the afternoon. The afternoon gets choppy again with a cross-on breeze.
From Wednesday the 29th through to the 9th of August, the surf gets pretty small and weak. Most days are under 3ft, with short periods (6-9 seconds) and the combined energy drops well below 100 most of the time. The wind is often cross-on or onshore, so the quality is poor. There’s a glimmer of hope on the morning of the 10th of August – a glassy start with 3ft of NNW swell and an 8-second period, giving us a combined energy of 171 (moderate). It’s surfable, but it’s ordinary. The afternoon goes back to choppy.
So, the standout is that Monday morning the 27th. It’s the only time the stars really align with a decent swell, proper direction, and glassy wind. The rest of the 16-day window is mostly a write-off for high-quality waves at Mundaka. If you’re a beginner, the 5ft might be a bit of a push. For the experts, it’s perfect. The crowds are often there, so expect company.
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.
