The Lowdown

Alright, let’s break it down for Mundaka. It’s a slow start, but there are a couple of windows worth getting excited about.

The very first session on Sunday the 30th of August is a beauty. Early morning, the water is 75°, which is much warmer than normal for this time of year. You’ve got a clean 5ft NW groundswell with a 10-second period, dead calm wind – glassy. The wave energy is moderate at 365. The swell direction is exactly where you want it from the NW for this river mouth. That’s the kind of morning you live for.

That afternoon the wind swings NW and picks up, turning it cross-on and choppy. The swell holds, but it’s gone.

Monday the 31st sees the swell push up a bit to 6ft, with energy at 524, but the wind is cross-shore in the morning and onshore in the afternoon. It’s messy. From Tuesday the 1st of September right through to Friday the 4th, it’s a proper flat spell. Swell drops off, periods shorten, and the wind never helps. The energy drops into double digits – weak.

We get a pulse of big energy on Saturday the 5th of September, with 6ft NW groundswell and a long 13-second period. The combined energy hits 1334, that’s strong. But the wind is cross-on from the NE, chopping it up. That long period groundswell can make a river mouth like this break a bit too quick and straight, so it’s a tricky, powerful one. Only for the experts.

A few more days of small, poor conditions until the morning of Monday the 7th of September. A little glimmer – clean 3ft NW swell, glassy, with light ENE airs. Energy is low at 141. Surfable, but very ordinary.

The next real standout is the morning of Sunday the 13th of September. Flat calm, clean 4ft NW swell, moderate energy at 493. Solid Sunday session.

And the absolute best is the morning of Monday the 14th of September. We’ve got a solid 7ft NW groundswell with an 11-second period, perfect direction, and it’s glassy. The energy is pumping at 1109. That’s serious Mundaka. That’s over 2m though, so it’s expert territory. The afternoon turns cross-on again, but that morning is the one to chase. It’s two weeks out, so keep an eye on it, but it looks like the crest of the whole forecast.

So, a lot of waiting. The 30th of August morning and the 14th of September morning are your two clear standouts. The rest is small or messy. Be patient for the good ones.

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.
