The Lowdown

Alright, Rusty here with the look ahead. Let's be honest, these first few days are a write-off. The surf is small, the winds are messy, and there's just nothing to get excited about. We've got a bit of a gap here until real swell shows up.

Alright, let's get into the week, starting now.

That Tuesday morning is no good. Tiny 3 ft WNW swell with a 6 mph westerly cross-breeze. The water's sitting at 73°, which is a touch warmer than normal for this time of year, but it doesn't help the surf. Tuesday afternoon and Wednesday are just more of the same – onshore winds and poor conditions. You'd be wasting your time.

Thursday morning, the 10th of September, is where we almost get a look in. The swell is a modest 4 ft from the NW, but the real hero is that SSE wind at just 3 mph, giving us glassy conditions. The combined energy is moderate (286). It's not a massive day, but that clean surface will make it fun on the right board. It's a shame the afternoon chops it up again.

Friday and Saturday are tiny again, so don't bother.

Now, this is the standout. Sunday morning, the 13th of September. Get ready. We've got a 5 ft NW groundswell pumping in with a long 13-second period and glassy WSW winds. That's the kind of combo that makes Mundaka (Basque Country) absolutely sing. The combined energy is strong at 841. This is a proper wave for experts only, the kind that will have those long, rifling left-handers. It's a river mouth, so that long period groundswell will wrap in perfectly. And with it being "often" crowded, you can bet there will be a crew out, but for a wave this good, it's worth it. The afternoon on Sunday gets a bit of a cross-breeze, so get your session in the morning.

Monday the 14th sees the swell easing a little to 4 ft from the NW, period still a solid 12 seconds. The wind is a light cross-shore from the east. It's a step down from Sunday but still a very good wave. After that, it's a slow fade out with smaller swell and increasingly onshore winds through the middle of the week, with a few ordinary mornings.

Looking further out, there's a spark of hope on the 19th (Saturday morning) – a clean 3 ft NW swell with an 11-second period and a light cross-offshore breeze. And again on the 20th (Sunday morning), we see a similar setup with a bit more size (4 ft) and a 12-second period. Both are worth keeping an eye on. The very end of the outlook, around the 22nd and 23rd of September, shows a strong NW swell (up to 6 ft, period 14 seconds) but it's getting smashed by strong onshore winds, making it a messy, blown-out affair that would be more interesting for kite surfers than paddle surfers.

All in all, your best bet is Sunday morning the 13th. That’s the one to circle on the calendar.

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.
