Mundaka Surf Forecast and Surf Report

Alright, Rusty here. Let’s take a look at what’s cookin’ over the next couple weeks. This outlook covers only the Mundaka region.

Right off the bat, it’s a pretty slow start. We’ve got a long dry spell with basically nothing worth paddling out for from the beginning of the period all the way through to the morning of Sunday, 6th September. That’s nearly four days of flat or poor conditions. The first real sign of life shows up on Sunday morning.

Sunday, 6th September morning is the standout of the whole run. The swell is coming from the NW at 5ft, period of 12 seconds – that’s a solid groundswell with real energy behind it. The combined energy is up at 522 (moderate to strong), and the real kicker is the wind: glassy, dead calm. At Mundaka, a river mouth setup, that 12-second period is gonna produce some beautiful, well-shaped lines. This is the session to aim for. The water temp anomaly is about average for this time of year.

Monday, 7th September morning is a bit of a letdown. Swell drops to 2ft from the NW but the period is a very long 15 seconds. That’s groundswell with lots of energy between sets, but the size is tiny. Combined energy is 349 (moderate), and the cross-shore wind is light. The long period might make it tricky at the beach break, but at Mundaka’s river mouth it could wrap in okay. Still, it’s marginal – just a maybe.

Wednesday, 10th September morning brings another window. Swell is back up to 4ft from the NW, period 10 seconds, and the wind is light and cross-offshore, so the wave faces should be clean. Combined energy is 337 (moderate). It’s not the big show, but it’s surfable and clean.

Friday, 11th September morning is glassy again, but the swell is only 3ft from the NW, period 10 seconds. Combined energy is 173 (weak to moderate). It’s ordinary but clean.

Saturday, 12th September morning sees a light cross-offshore breeze again, with 3ft NW swell at 10 seconds. Combined energy 173. Same story: clean but nothing special.

Sunday, 13th September morning – swell drops to 3ft NW, period down to 8 seconds, so it’s a shorter-period windswell. Combined energy is 105 (weak). Wind is cross-offshore, so it’ll be clean but weak.

Monday, 14th September morning offers a tiny 1ft NW swell with offshore wind – clean but basically flat.

Tuesday, 15th September morning has a glassy start with 3ft WNW swell, 10-second period, combined energy 126 (weak). Ordinary.

The final notable window is Wednesday, 16th September morning. Swell jumps to 5ft from the NW, period 12 seconds, combined energy 667 (strong). That’s a proper sized groundswell. But the wind is light cross-onshore, which will put a bit of texture on the face. The period is long enough that Mundaka’s river mouth setup might still produce good shape, but the wind is not ideal. It’s marginal but could be worth a look if the wind backs off.

Overall, Sunday morning 6th September is the clear winner. Glassy conditions, solid 5ft groundswell from the NW. That’s your session.

Rusty.
