The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cooking for Mundaka over the next couple of weeks.
Right off the bat, it’s a bit of a slow start. The first few days are a write-off. We’re looking at a stretch of poor conditions from the 7th to the 9th, with small, choppy, and cross-onshore winds ruining any chance of a decent wave. It’s a frustrating wait, but it’ll be worth it for those who are patient.
The real action starts to sniff around on Thursday morning, 10th September. The wind goes glassy, and the swell picks up to a clean 4ft from the NW with a decent 10-second period. The water is sitting at 73°, which is a touch warmer than normal for this time of year. The combined energy is moderate at 286. This is the first real window to get a wave.
Then we get a dry spell again until Sunday morning, 13th September. This is the standout. The wind is glassy, and we’ve got a solid 5ft swell from the NNW with a long 13-second period. The combined energy is strong at 796. This is a proper groundswell, and at Mundaka, that long period will set up some beautiful, long lines. The only catch is that this spot is for experts only, and crowds are often an issue here. For the experienced surfer, this is the session to circle.
After that, the week ahead has a few more promising moments. Wednesday morning, 16th September sees glassy conditions with a 4ft NW swell, period 11 seconds, and good energy at 429. Thursday morning, 17th September looks similar with glassy winds and 4ft waves. Then Friday morning, 18th September brings a slightly bigger 5ft NW swell with a 9-second period, also glassy, with moderate energy at 437. Saturday morning, 19th September, you’ll find 5ft waves from the NNW with a short 7-second period, but the glassy wind will keep it clean.
The end of the run, around the 21st and 22nd, looks like it gets blown out by strong winds again, so the first week of the second week is the real window of opportunity.
Overall, the best option is the Sunday morning, 13th September session. The long period groundswell from the NNW with glassy conditions is the best combination of size and quality on offer. Don’t sleep on the 16th, 17th, or 18th either, as they offer clean, manageable waves with lighter winds.
Rusty out.

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.
