The Lowdown

Alright, this is Rusty checking in on the Mundaka river mouth, and I’m not gonna sugarcoat it: the first part of this stretch is a tough watch. A lot of junk out there for several days. But you hang around, and there’s a proper session waiting way down the line that could fire. The water is sitting around 75°, which is way warmer than usual for this time of year, so at least you won't be cold while you're waiting.

Things start off Tuesday the 25th and Wednesday the 26th of August with nothing worth paddling for. Tiny, weak, poor-quality surf. Honestly, leave the board in the truck.

Thursday the 27th is a total washout. By Friday the 28th, it gets a little more interesting. The morning shows a clean 5ft NW swell rolling in with a moderate cross-off breeze, but the energy is still a bit messy. The afternoon gets bigger to 6ft NW, but that wind swings onshore at 19 mph and trashes it. Not the day.

Now, Saturday the 29th of August is where we get our first real glimmer. The morning is a beaut: a clean 5ft NW swell, glassy conditions with a slight offshore touch from the ESE at only 3 mph. That’s the kind of morning that gets the pulse going. The wave energy is solid for a proper work-out. This is the best session in the first week, and the cleanest conditions you’ll see for a while.

Sunday the 30th holds some OK waves in the morning – 4ft NW and dead calm – but it’s a bit ordinary and weak. Monday the 31st and Tuesday the 1st of September are marginal, with the swell bumping up to 5ft NW, but the winds are messy.

Hold on for Wednesday the 2nd of September. This is the other standout. The morning session is glassy, with a clean 5ft NW groundswell pumping in. The offshore wind from the west at just 3 mph will have the lines looking absolutely perfect. That’s a top-shelf Mundaka morning.

The wait gets real after that. The swell drops off hard, with weak, poor conditions lasting through the rest of that week and into the next. We’re talking days of small, onshore dribble. Nothing to write home about.

But then, out of the blue, Tuesday the 8th of September shows up. This is your wildcard. A massive 12ft NW swell is forecast, with insane wave energy. That’s expert territory only – way too big for beginners. The wind is just a light cross-shore, so it could be manageable. For the experienced crew, this is the kind of day that can make the whole outlook legendary. It's a long way out, so keep an eye on it, but it has serious potential.

Wednesday the 9th then drops back to a still-chunky 6ft NW, but the wind shifts cross-on, chopping it up.

So, to wrap it up: the clear winner is Saturday the 29th of August for that perfect glassy 5ft NW right-hander. And the absolute big one to watch is Tuesday the 8th of September, if you’ve got the skills and the nerve for an 12ft NW beast at Mundaka.

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.
