The Lowdown
Alright, surfers, let’s get into it. This is Rusty, and I’m looking at the 16-day stretch for our local spot.
First off, I gotta be straight with you – the next week and a half is a tough one for Mundaka. We’re looking at a whole lot of flat, weak, and messy conditions. The first real pulse of energy doesn't show up until Monday, July 20th, but it’s still a bit of a dog with a northerly swell that’s only 4ft and a short period of 7 seconds. The wind is cross-onshore, so it’s not going to be clean. The combined energy is only moderate at 135, so it’s not exactly packing a punch.
The next few days, from the 21st to the 24th, are more of the same – small, short-period NW and N swells, with the wind mostly onshore or cross-onshore. The water temp is a massive 75°, which is 6° warmer than normal, very unusual for this time of year. The water is a lot warmer than you’d expect, so you might want a thinner suit.
The real standout window finally starts to open up on the morning of Monday, July 28th. We’ve got a solid NW swell at 6ft with a period of 8 seconds, pushing the combined energy up to a strong 433. The wind is light and cross-onshore, so it’s a bit textured, but it’s the first real surf of the week. The afternoon stays clean-ish with a 5ft NW swell.
The best of the best, though, is the morning of Thursday, July 30th. The swell drops to 3ft from the NW, but the period stretches to 10 seconds, giving it some real groundswell feel. The combined energy is still a healthy 198. But the clincher is the wind: it’s glassy. That’s a major positive. The river mouth will be clean and lined up. This is the one to circle. The morning of Friday, July 31st, is also glassy, with a 2ft NW swell, but it’s a bit smaller. For a long-ranger, the morning of Saturday, August 1st, looks promising, with a clean ESE cross-offshore wind and a 2ft NW swell, but that’s a while away and less certain.
Keep in mind, Mundaka is an expert river mouth wave and it’s consistent, but it’s often crowded. With the better windows coming up, you’ll have to fight for your 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.
