The Lowdown
G’day, I’m Rusty. Let’s talk about what’s on the cards for Mundaka over the next couple of weeks.
Right off the bat, I’ll be straight with you – the first week or so is pretty grim. We’re looking at a long, dry spell with no real standouts. From Saturday the 25th right through to about Friday the 7th of August, it’s mostly a write-off. There’s a few mornings where the ocean might be glassy, but the swell is tiny, or the wind is all wrong, and the energy is just not there. You’ll see some poor surf conditions and scores are flat. That’s a solid two-week gap of nothing worth paddling out for, with only a couple of faint glimmers in the mix.
Now, hold onto your leash because things finally turn around on Sunday the 9th of August. That morning at Mundaka we get a proper shot. A glassy dawn with the wind swinging light from the west-northwest, and a clean 5ft swell rolling in from the west-northwest. Combined wave energy is a solid 268, which is moderate – enough to get the river mouth working. The swell period is a touch short at 8 seconds, so it’s not a deep-water groundswell, but for a river break like Mundaka that likes a bit of push, this is the best we’ve seen in a while. The wind is glassy – absolutely perfect for a smooth, lined-up left. Keep in mind, this spot can get crowded, and it’s a consistent break, so expect company on the peak. The water temperature is sitting at 76°F, which is much warmer than normal for the time of year – that’s over 5°F above average, so it’s properly unusual. That’ll feel like a bath compared to what you’d expect.
Later that same Sunday afternoon, the swell jumps up to 8ft from the west-northwest, pushing combined energy to 777 – that’s strong, bordering on burly. But it comes with a light cross-onshore breeze and a drop in quality, so it’s one for the experts only. Anything over 8ft is big here, so keep that in mind.
Bottom line: nothing happening until the 9th of August, but that Sunday morning is your window. Get on it while it’s clean.
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.
