The Lowdown

Alright folks, Rusty here. Let’s get into it.

Well, I’ve gotta be straight with you – this outlook is a tough one for the Basque Country. The entire 16-day window is a near-blank slate for quality surf, with no real standouts that get the heart pumping. We’re looking at a long stretch of "poor surf conditions" dominating the charts, with only a couple of fleeting moments that are barely worth a mention.

The first bit of hope pops up on the morning of Tuesday, 28 July. The wind goes glassy at Mundaka, with a 4ft swell out of the NW and a period of 9 seconds. The combined energy is moderate (249), and the glassy conditions will make it clean. But the report says it’s "surfable waves but very ordinary conditions" – so it’s not the classic Mundaka magic. This is a session for the patient local who doesn’t mind a slower day.

Then, on Thursday, 30 July morning, we get a brief window of clean surf with cross-offshore winds from the SE. The swell drops to 3ft from the NW, still with a 9-second period. The energy is weak (108) and the conditions are described as "surfable but very ordinary" again. It’s a small, clean wave for a longboard or a fish, but nothing to get excited about.

The Sunday, 2 August morning offers another glassy spell, with a 4ft NW swell and a 6-second period (short period, so less grunt). The energy is moderate (145), but again, it’s just "ordinary". The wind is off, but the swell lacks the power and direction to really fire up the river mouth.

For the rest of the period, it’s a mix of onshore and cross-shore winds, small chop, and weak energy. The combined energy values are mostly in the double digits or low triple digits, indicating weak to moderate wave energy at best. The only real spike in energy comes on the 27th and 1st of August, hitting 496 and 341 respectively, but those days are plagued by cross-on winds and lumpy conditions, making it a messy, blown-out affair. Honestly, that setup looks more interesting for kite surfing than paddle surfing, with strong wind and decent swell size but poor quality.

So, what’s the call? The best on offer is the glassy morning of the 28th of July, but it’s a low bar. The entire forecast is a write-off for any serious surfing. That’s a blank run, and for this area, it happens. The forecasts can change, but right now, I’d keep the boards in the bag and wait for the next pulse.

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.
