The Lowdown
Alright, let’s break it down for Mundaka. The first few days are dead flat, not worth a second look. Tiny swell, short period, wind is all over the place. Don’t waste your time.
It starts to get going on the morning of Friday, August 28th. We’ve got a swell of 5ft from the NW, with a 10-second period. The combined energy is moderate at 527, and the wind is a gentle offshore from the SSW. That’s the ticket – clean, offshore conditions. This is the first real chance for a wave, and it’s going to be a good one. The water temp is about average for the time of year.
The real standout is the morning of Saturday, August 29th. There’s a solid 7ft swell from the NW, with a 10-second period. The combined energy is strong at 904, and the wind is a light cross-offshore from the WSW. The wave comment says “expect very good surf conditions.” This is the best of the 16-day window. The wave is going to be powerful and lined up. It’s a cut above the rest. The crowds here are often around, so get there early.
Sunday the 30th is still rideable, with 4ft from the NW and glassy conditions in the morning, but the energy is lower at 244. It’s a good backup if you miss the Saturday peak.
After that, the swell drops off. The rest of the week into early September is mostly small, weak, and lacking any real punch. The morning of Monday, September 7th, shows a glimmer of hope with 4ft from the NW and a longer period of 12 seconds. The combined energy is back up to 463, and the wind is a light cross-offshore from the east. This could be a solid final session, but it’s a long way out and the confidence is lower.
So, to sum it up: the best surf is on the morning of Saturday, August 29th. The Friday morning on the 28th is a close second. Don’t expect much else in between.

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.
