Hanamizu River Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what Hanamizu River has in store for us over the next couple of weeks.

Right off the bat, I gotta be straight with you – this is a tough run of swell. We’re looking at a long stretch of small, weak energy and conditions that just aren’t playing ball. The first several days are a write-off for any proper surfing. From Sunday the 9th right through most of the following week, we’ve got tiny waves and mostly messy or poor conditions. The energy is way down, barely registering triple digits in the combined swell department, and the wind isn’t giving us a break for the most part.

The first real glimmer of something worth paddling out for shows up on the morning of Monday the 10th of August. It’s not a classic, but the glassy conditions late in the day are a nice change. We’re talking about 2 ft of SSW groundswell at 11 seconds. The combined energy is still low at 111, but that glassy surface is a major positive for a wave this small. For a beginner-friendly sandbar spot like this, that afternoon window is your best bet for a fun, easy paddle without the wind ruining it.

We then drop back into the doldrums for a solid week and a half. Clean cross-off winds pop up from the 13th and 14th, but the swell just isn't there – we’re down to 1 ft. Even with good wind, you can’t make waves out of nothing.

The standout event, and the only time this forecast gets interesting, arrives on Saturday the 22nd of August in the afternoon. A pulse of S swell pushes in at 4 ft with a 12-second period. The combined energy jumps to 351 – that’s a solid, moderate pulse of energy for this river mouth. The wind is light and cross-onshore, which is manageable. It’s not perfect, but after two weeks of nothing, this is the one window that offers a real, rideable wave. If you’ve been jonesing for a surf, mark that afternoon. It’s still a beginner-friendly setup, so the 4 ft is doable, just keep an eye on the tide.

Then it fades again into the final days of the window. It’s a long, flat run for Hanamizu. We’ll have to hope the forecasts change. That Saturday afternoon is your only real shot. Rusty out.
