The Lowdown
Alright, Rusty here. Let’s talk about what’s on the menu for Mundaka over the next couple of weeks.
We’ve got a pretty classic pattern shaping up: a few mornings of real hope this first weekend, then the surf drops off into a long, quiet stretch, before a pulse of longer-period energy tries to show up in the second week. It’s not going to be a non-stop show, so you need to pick your windows.
The best of the whole outlook is hands down Sunday, August 30th, in the morning. We’ve got a clean 5 ft of NW swell, with a period of 10 seconds, and the winds are dead calm—glassy, perfect conditions. The combined energy is 478 (moderate) and the water’s sitting at 75°, which is much warmer than normal for the time of year, so you can ditch the thick winter suit.
Saturday morning, August 29th, is also a strong contender. Similar story: 5 ft from the NW, glassy offshore from the ESE, and a combined energy of 397 (moderate). That’s a solid session.
After Sunday afternoon, the onshores creep in, and the surf fades fast. From Wednesday morning, September 2nd, all the way through to Friday, September 4th, the swell drops to ankle-to-knee high—under 2 ft. That’s a three-day gap of pretty much no surf.
Things get interesting again around Saturday morning, September 5th. Swell jumps back to 4 ft from the NW, but with a very long period of 12 seconds, driving the combined energy up to 674 (strong). Winds are light offshore from the east in the morning, making for glassy conditions. That’s a promising call for a point break like Mundaka, but keep in mind, that long period energy can make things a little walled up. It’s still the standout of the second week.
Sunday morning, September 6th, offers a similar setup: 5 ft NW at 12 seconds with light offshore winds—another solid option, though slightly less energy at 578 (moderate).
The rest of the second week is a mixed bag of smaller swells and onshore winds, nothing worth setting the alarm for.
So for the best of the best: Sunday, August 30th morning. The next best is Saturday morning, August 29th. After that, keep your eye on Saturday morning, September 5th for a late-season groundswell treat.
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.
