The Lowdown
Alright, let me tell you how it’s looking for your next couple of weeks. Honestly, it’s a bit of a quiet stretch for Mundaka. We’re looking at a solid gap right from the start with nothing worth paddling out for until we get well into the second week. There’s just no energy in the water for most of this run.
The first real chance of anything rideable comes around Monday the 18th of August. Even then, it’s not screaming, but you’ll see a bit of a pulse from the NW, pushing waist to maybe chest high waves. The wind is light and cross-shore on the Tuesday morning the 18th, so it might clean up a touch, but the swell energy (163) is only moderate. It’s not the classic Mundaka power.
The standout of this whole outlook, and I mean the only day that gets me a little excited, is Thursday the 20th of August. It’s still a way off so don’t bank on it, but the models are showing a solid NW groundswell, around 3ft to 4ft, with a long 11 to 12 second period. That combined energy reading (279) tells you there’s some proper push behind it. The direction is exactly what this river mouth loves – solid NW. The morning is looking glassy with a light offshore easterly. If that lines up, Mundaka could have some nice, clean, lined-up waves peeling down the bank. The water is warm, sitting at 75°F which is *much* warmer than normal for this time of year, so you’ll be comfy in a spring suit.
For the rest of that week, everything else is small and messy, with cross-onshore winds and poor conditions. The Friday the 21st morning might have a little bump of NW swell but the winds aren’t great.
So, to be straight with you: it’s a long, quiet wait until that Thursday the 20th. If you’re itching for a wave, that’s your target. Just remember, we’re talking 14 days out – keep an eye on the forecast, but don’t hold your breath yet.

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.
