Mundaka Surf Forecast and Surf Report

Alright, I’m Rusty, and I’ve been staring at the charts for this stretch. Let’s break it down.

Right now, the surf is flat and messy. We’ve got a long run of small, weak, and choppy conditions from Monday the 17th all the way through to Wednesday the 19th. Swell heights are barely pushing 2 ft and the period is short, like 6 seconds. The wind is mostly cross-onshore or onshore, so don’t even bother waxing up. The water’s sitting at 76°, which is much warmer than normal for this time of year, so that’s nice if you’re just floating around.

Thursday the 20th morning is the first glimmer of hope. The swell picks up to 4 ft from the NW, period jumps to 11 seconds, and the wind goes glassy. That’s clean. The wave energy is moderate (294). You’ll want to be at Mundaka (river mouth) for that one. The swell direction is NW, which is right in the sweet spot for this break. It’s a short window though—by afternoon it’s back to onshore and messy.

The rest of that week and into the next is pretty grim. Friday the 21st through Sunday the 23rd is all cross-onshore wind, lumpy, and small. The swell stays under 5 ft but the wind just ruins it. There’s a bit of a bump on Saturday the 22nd morning with a 3 ft NW swell, but it’s cross-shore wind and the energy is weak (157).

Then we hit a real gap. Monday the 24th through Thursday the 27th is a write-off. Swell drops to 1 ft to 4 ft, all short period, and the wind is never clean. You’re looking at 4 days of nothing.

But hold on—Friday the 28th gets interesting. The swell jumps to 6 ft from the NW in the morning, and the energy is strong (513). The wind is light cross-shore, so it’s not perfect, but it’s surfable. By Friday afternoon, the swell is 10 ft from the NW, period 9 seconds, and the energy is very strong (1351). That’s big, but it’s onshore wind, so expect some chop. This is expert-only territory.

Now, the standout. Saturday the 29th morning is the real deal. We’ve got a 15 ft NW swell with a 14-second period—that’s a long-period groundswell. The wind is glassy, WSW at 3 mph. The energy is through the roof (7198). This is exceptional surf, but only for experts. Mundaka is a river mouth, so that long-period swell will wrap in nicely, but it’s going to be big and powerful. If you’re not an expert, stay out of the water. The water temp is still warm, but we don’t have the anomaly for that date.

Sunday the 30th morning drops to 7 ft from the NW, period 10 seconds, with light cross-shore wind. The energy is still strong (1048), but it’s not as clean. Monday the 31st is a write-off with fresh cross-shore wind and rain.

So, the best bet is Saturday the 29th morning at Mundaka. It’s the only real standout. Get there early, and don’t forget your big-wave board.
