The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Mundaka over the next couple of weeks.
Right off the bat, I’ll be straight with you – this is a tough one. The forecast is showing a long, dry spell with hardly any surf to get excited about. For the first ten days, from the 15th right through to the 24th of August, it’s pretty much a write-off. The swell is tiny, the wind is a mess, and the wave comment is “poor surf conditions” the whole way through. You’re looking at a solid ten-day gap with nothing worth paddling out for.
The only real glimmer of hope comes much later, and it’s a bit of a long-range promise. On the morning of Thursday, the 27th of August, we finally get a bit of life. The swell picks up to 4ft from the NW, with a period of 11 seconds – that’s a proper groundswell, nice and clean. The wind is a light cross-off shore from the WSW, which is a major positive for Mundaka, cleaning the wave right up. The combined energy is moderate at 287, and the forecast is calling for “expect good surf conditions”. This is the standout session of the entire outlook. It’s not huge, but for this spot, with that glassy feel and the right direction, it’s the best on offer. The water temp is a very warm 76°F and the anomaly is 5°F warmer than usual, so it’s much warmer than normal for this time of year.
But don’t get too carried away. The afternoon of the 27th gets blown out by a strong cross-shore from the WNW. The morning of Friday the 28th also looks clean with glassy conditions, but the swell drops back to 3ft and the energy is weak at 100. It’s surfable, but nothing special.
So, to sum it up: the first ten days are a bust. The only real session to aim for is the morning of Thursday the 27th. It’s a long way off, so keep an eye on the forecast, but that’s your best bet for a clean wave 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.
