The Lowdown
Alright folks, Rusty here. Gotta be straight with you on this one. Lookin' at the next 16 days for Mundaka, and it's a bit of a heartbreaker. The first two weeks are a total write-off. We're talking about a solid 14 days of flat, weak, or just plain onshore junk. The swell is tiny, the period is short, and the wind is mostly blowing the wrong way. It's gonna be a long stretch of staring at a lake.
We get a little flicker of hope on the 30th of July, Thursday afternoon, when a bit of a bump shows up. There's a moderate cross-onshore wind, but the swell jumps to 5 ft from the NW, and the period stretches to 13 seconds. The combined energy hits 850 (moderate wave energy), which is the first real sign of life. But the wind is still messy, so it's a "maybe if you're desperate" kind of session.
The true standout, the one that finally gets the blood pumping, is the morning of Friday, the 31st of July. This is the one. The swell is a solid 6 ft from the NW, with a 12-second period, giving it some real power. The combined energy is a solid 928 (moderate wave energy), and the key here is the wind: glassy. Dead calm. That's going to make those famous Mundaka walls as clean as a whistle. The water temp is a toasty 75° which is much warmer than normal for this time of year, so you'll be fine in a shorty. Keep in mind this is an expert wave, and with conditions like that, the crowds are likely to be thick. This is a world-class river mouth setup, and a long-period NW groundswell is exactly what it was built for. Don't sleep on it.
The afternoon of the 31st is still a decent option with 6 ft NW swell, but the wind swings cross-onshore and chops it up, so get on it early.
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.
