Asakawa Surf Forecast and Surf Report

Alright, this is Rusty.

Let’s check the pulses up at Asakawa. We’ve got a quiet start, but the back end of this run has some serious muscle building. The water is sitting right around 76°, which is a bit cooler than usual for this time of year, so don’t get caught without a little extra rubber for that first dip.

The first couple of days are a total dud. Sunday the 5th is tiny, weak, and blown out with rain. Monday the 6th is hardly better with a cross-onshore breeze and no energy to work with. You’re looking at a solid gap of a few days where you can leave the board in the car.

We finally get a pulse on Tuesday morning the 7th. Swell bumps to about 4ft, but it’s cross-shore and has a very long period of 12 seconds. That’s classic groundswell, and on a point like Asakawa, that long-period juice can really draw some nice lines. The energy is moderate, but it’s still just a marginal call.

Now, hold tight. From Wednesday morning the 8th, the ocean wakes up. The swell jumps to 7ft with a 16-second interval, and the energy gets strong. It’s onshore, but the power is there. By Wednesday afternoon it’s 10ft and the energy is very strong. That’s getting into expert-only territory, as 10ft at Asakawa with that period will have some serious grunt.

Thursday the 9th holds that 10ft to 12ft range with a consistent 16-second period, but the wind turns cross-onshore, chopping the faces up a little. Still a major swell. Friday the 10th is the peak for raw size, with the swell hitting 13ft and the energy going completely bonkers. This is a massive, powerful groundswell. If you aren’t a hardcore expert, stay on dry sand.

The standout window, and the one I’d lock in, is Saturday morning, July 11th. The swell is still a solid 13ft, but the wind goes glassy – absolute perfection. The energy is still enormous. For the experts, this is going to be an all-timer session. Asakawa with a 13ft, 17-second groundswell and zero wind? That is the definition of a beast. It will be clean, terrifying, and incredible.

After Saturday, the swell fades quickly. Sunday the 12th is still a solid 8ft, but the wind turns and the energy drops. By Monday the 13th, it’s back down to a glassy 4ft in the morning, which could be a fun, easy session to finish the run. The rest of the second week falls apart into smaller, weaker swells and short periods; nothing worth chasing. The last few days are tiny and flat.

The one to go for: Saturday morning, July 11th. It’s the big wave call of the run. Clean, glassy, and massive.

Rusty.
