The Lowdown

Alright folks, Rusty here with a look at this Basque stretch of coast for the next couple of weeks. We’ve got some serious potential bubbling up, but we’ve got to earn it through a bit of a bumpy start.

Right out of the gate for the early part of the week, it’s a write-off. Think onshore winds, short-period chop, and flat-looking energy. We’re looking at a real struggle from Monday the 14th through to Thursday the 18th. The wind is just not playing ball, with cross-onshore and onshore flow making a mess of things.

The first genuine glimmer comes in on Friday the 18th afternoon. The swell builds, but the word is *marginal* thanks to a light cross-onshore breeze, so don’t get your hopes up yet.

Now, hold on to your boards, because Saturday morning the 19th is the standout. This is the moment. We’ve got a clean 7ft groundswell grinding in from the northwest. The period is a meaty 13 seconds, meaning real power. The wind? It’s dead glassy with a light SSE breeze. For Mundaka, this is as good as it gets – a river mouth point break that will turn that long-period NW swell into proper, shaping waves. The water is sitting at 73°, which is a good 4° warmer than usual for this time of year, so the wetsuit situation feels a bit more tropical.

Monday morning the 21st is the other absolute gem. We’re looking at 7ft of NW groundswell with a 14-second period. With the wind going dead calm (0 mph) and glassy conditions, it’ll look like a mirror out there. The energy is pumping, which means plenty of push. This one’s strictly for the experts though – that size on a river mouth is powerful and demanding.

After that, the quality drops off. The afternoons get cross-onshore, and the days that follow ease off in size or get messy with wind. The Saturday morning the 26th is worth a mention for the hopefuls: a clean 4ft swell from the NW with a light offshore S wind blowing at 6 mph. It won’t be pumping like the big days, but it’ll be clean and fun for a session.

The very tail end of the window, Monday the 28th, looks nasty with a strong breeze and lumpy cross-chop. The season gives, and the season takes away.

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.
