The Lowdown

Alright folks, Rusty here. Gotta be straight with you – the next week and a half is a bit of a write-off for Mundaka. We're staring at a real flat spell, so don't even bother checking the cam for the first several days. The good news is there's a proper pulse lining up for the back half of the window, but it's a long wait.

The first real glimmer of something half-decent shows up on the morning of Monday, 12th August. Even then, it's a tiny 3ft from the WNW with a short 5-second period, and the energy is weak (90). It's glassy though, which is a plus, but you're really just scratching around for a knee-high dribbler. Don't get your hopes up.

Then we hit a proper dead zone from the 13th through the 15th. Tiny, weak, and messy. Not worth a second look.

The first sign of life comes on the morning of Sunday, 16th August. The swell starts to show its teeth – 4ft from the NW, a 10-second period, and the energy jumps to 368. It's still a "marginal" call, but with a light cross-shore breeze, it's the first time the river mouth might actually have a pulse. Still, it's not the main event.

Monday, 17th August is another tease. Glassy in the morning with 2ft and 97 energy, but it's just too small to get excited about. The real deal is brewing.

Now, mark your calendars for Tuesday, 18th August. This is the standout. The morning session is where it's at. We're looking at a solid 8ft swell from the NW, with a 9-second period. The combined energy is a massive 1034 – that's a lot of power heading into the point. And the wind? Glassy. Absolutely dead flat. This is a proper, clean Mundaka wave. The kind that makes you forget about the flat spell. The afternoon gets a cross-onshore wind that'll chop it up, so hit the dawn patrol.

Wednesday, 19th August is still holding onto that energy. The morning shows 7ft from the NW, with 954 energy. The wind is cross-shore, so it'll be a little lumpy, but there's still a heap of water moving. The vibe is "marginal" for the conditions, but don't be surprised if it's still fun. Afternoon gets messy again.

For the crowd situation – Mundaka is "often" crowded, so when that 8ft glassy morning hits on the 18th, expect a lineup. It's a world-class wave, everyone knows it. And remember, this is an expert-only wave, especially when it's over 8ft as it will be on the 18th and 19th. That kind of power on a river mouth is no joke for beginners.

So, the long and short of it: suffer through a long, flat, boring first week, and then get ready for a proper mid-August session on the Tuesday morning. It's a long-range call, so it's promising but not locked in.

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.
