Mundaka Surf Forecast and Surf Report

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.
