The Lowdown
Alright folks, Rusty here with the long-range look at Mundaka. We've got a bit of a slow start, but there's some serious magic brewing if you can wait it out.
The first real window of opportunity doesn't arrive until Sunday the 19th. Before that, the wind is just all wrong, with cross-shore and cross-onshore breezes messing up what little swell there is. From the 13th through the 18th, it's a write-off – a mix of poor conditions and marginal surf that just isn't worth the paddle out.
Now, let's talk about the standouts. The absolute best session of the entire 16-day run is going to be Saturday morning, September 19th at Mundaka (Spain) . That's the one to circle on the calendar. We've got a solid 7ft NW swell rolling in, and with a period of 13 seconds, that's a proper groundswell full of energy – the combined energy reading is a massive 1648 (strong to very strong wave energy). The wind? Dead calm, glassy, from the SSE at just 3 mph. That means perfection for a river-mouth wave like this. The water's sitting around 73°F, which is much warmer than normal for this time of year, so you'll be comfortable out there. Keep in mind, this is an expert-only wave that's consistent, and crowds are often an issue here. With this forecast, you can bet it'll be packed. If you can get a peak, you're in for a session of a lifetime.
The other big shout is for Monday morning, September 21st. Another glassy morning with a light SW breeze at 3 mph. Swell's a touch smaller at 6ft, still from the NW with that same 13-second period, and the energy is still powerful at 1044 (strong wave energy). It's going to be very good surf, just a notch below the Saturday session. The afternoons on both these days get chopped up by a cross-onshore wind, so make sure you're on it first thing.
After that, things start to fade. There are a few mornings with marginal surf and iffy winds, but nothing that'll get the heart pumping like that weekend. By the time we hit the 25th, the swell has dropped right off to 2ft, and the 27th is pretty much flat. There's a long gap of poor conditions from the 22nd onwards, so don't expect much in the second week.
So, to sum it up: the first week is a wash, but the second week has a couple of absolute belters. The 19th is the king, and the 21st is the loyal prince. Get on it.
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.
Mundaka is 2 km (1 miles) from Bermeo. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Bermeo. Bermeo has rooms for a wide range of budgets as well as car hire and transport links.
