Hanamizu River Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it.

The next 16 days look like a real mixed bag for Hanamizu River. The best surf is definitely going to be cramped into the first few days, with a solid pulse of groundswell rolling in. After that, things drop right off, and we’re looking at a long stretch of small, tired waves pretty much from the 10th of August onwards.

We kick off Monday the 3rd with some cross-off wind from the NNE at 25 km/h, but the swell is a tiny 2ft to 3ft. That’s not doing much, even with a super long 16-second period. The energy is weak to moderate (277-449). Not worth paddling out for.

Tuesday the 4th is where it starts to get interesting. The swell jumps to 5ft in the morning, then 6ft in the afternoon, still from the SE with that long 16-17 second period. Combined energy is strong (1059-1694). The wind is cross-off in the morning, turning cross-shore in the afternoon. These are groundswell waves, so the river mouth setup should be handling them better than a beach break, but the tide conditions are questionable. It’s surfable, but not a standout.

Wednesday the 5th is the real deal. Morning sees 8ft of SSE swell at 16 seconds, with clean cross-off wind from the NNE at 25 km/h. The energy is already very strong (3731). The swell jumps to 10ft by afternoon, SSE at 16 seconds, with a moderate cross-shore breeze. That’s a big, powerful swell. For a beginner spot, this is now too big – only for experienced surfers. The morning window is the cleanest, but by afternoon there’s a cross-chop. This is the best on offer, but it’s not perfect.

Thursday the 6th holds solid, with 10ft of S swell in the morning, clean cross-off wind, and very strong energy (4061). The afternoon brings a risk of thunderstorms and a cross-onshore wind, so the morning is the only real window.

By Friday the 7th, the swell drops to 8ft, still S, but the wind is messy. The best session is the morning with a cross-shore wind, but it’s not clean. Saturday the 8th sees the swell drop further to 6ft, and the wind is cross-shore or cross-onshore, so it’s choppy. Sunday the 9th is back to some clean cross-off wind, but the swell is down to 5ft.

From Monday the 10th onwards, it’s a long, slow decline. The swell drops below 3ft, and the energy is weak (under 600). There are a few windows with clean offshore wind, like the 14th of August afternoon with a solid 20 km/h offshore breeze from the NNW, but it’s only 2ft of swell. The energy is weak (125). It’s a long, quiet period for Hanamizu River.

The standout for the entire forecast is the morning of Wednesday the 5th of August. That 8ft SSE swell with clean cross-off wind is the biggest and cleanest you’ll see. The morning of the 6th is also a solid option, but the 5th is the pick of the 16 days. After that, the magic is gone.

Rusty.
