The Lowdown
Alright folks, Rusty here. Let’s be straight with you: the next couple of weeks around here are going to test your patience. The main window of proper surf is a long way off, and until then, we’re looking at a lot of small, messy, or wind-affected conditions. Don’t get too excited about the early days, but there is a light at the end of the tunnel if you’re willing to wait.
The story starts with a whole lot of nothing. From now through the 23rd, we’ve got a run of tiny waves and poor quality. It’s a big gap, more than a week of mostly onshore slop and ankle-biters. The combo energy is weak, with readings mostly in the double digits, and the swell direction is all over the place. You’d be wasting your time and fuel checking it.
Now, the first real glimmer of hope arrives on Sunday the 24th. That morning, the swell finally shows up, with a solid 8ft of west-northwest groundswell. The energy jumps way up to 811 in the morning, which is a big kick of power. The catch? The wind is cross-onshore, which is going to put some chop on it. It’s a different story in the afternoon, though. The swell pushes to 8ft, and the energy reading climbs to a hefty 1131. This is serious, powerful surf, but the wind is going to be howling onshore from the northwest at 16 mph, making it a full-on mess. For Mundaka, this is heavy, expert-only territory. The wave size is over that 8ft mark, so it's not for the faint of heart, and the wind is going to make it a battle. This is the day for the big dogs only, and honestly, the conditions look more like a kite-surfing session than a clean paddle-out.
But then, the real standout comes on Monday the 25th. This is the one you circle on the calendar. That morning, the wind drops dead, glassy, with a calm 0 mph breeze, and the swell is still solid at 5ft from the northwest. The period is a healthy 9 seconds, bringing in some proper energy at 304. The water is glassy clean. This is the day for Mundaka to shine. That size, clean conditions, and the right direction – it all lines up. This is the pick of the whole window. The only downside is that with conditions like that, you can expect Sunday morning crowds to be likely, so get there early. After that, the swell fades fast back into the small and messy stuff for the second week, with nothing else worth chasing.
One last thing: the water temp is sitting at 75°, which is 4° warmer than normal for this time of year. That's a significant jump, so you can ditch the booties and enjoy the warm water on that standout day.
So, hang tight. It’s a long, flat stretch, but that Monday the 25th looks like it could be worth the wait. It’s a promising long-range call, but forecasts can change, so keep your fingers crossed.
Stay stoked.
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.
