Hanamizu River Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s break down what’s coming at Hanamizu River. The next week and a half is a bit hit and miss, but there’s one clear window to get excited about.

The first chance to paddle out is Thursday morning, July 9th. We’ve got a 5ft SSE swell with a long 14-second period, giving us moderate wave energy (937). The water is sitting at 75°, which is a touch colder than normal for this time of year. The SE wind is light and onshore, so it’s not perfect, but it’s a start. The afternoon turns choppy as the wind picks up from the south, so the morning is the move.

Friday, July 10th, brings a bigger pulse, with 6ft to 7ft from the S and SSE, with a very long 15-16 second period. This is proper groundswell, and the energy jumps to strong (1410-2141). The catch is the wind. Friday morning is okay with a light SE breeze, but by afternoon it’s a moderate S cross-onshore messing things up. The weekend looks the same story: solid swell but lumpy conditions.

Now, here’s the standout. Sunday morning, July 12th. The swell holds at 6ft from the SSW with a very long 16-second period, and the energy is still strong (1694). The wind drops to nothing—glass. That’s the magic window. The forecast is excellent for experienced surfers, and with that size and period, it’s going to be a powerful, clean wave. The best we’ve got. Sunday afternoon stays clean with lighter 5ft swell and glassy conditions, but it’s a drop-off in size.

After Sunday, the energy crashes. From Monday, July 13th, right through to Saturday, July 19th, we’re looking at a real dry spell. Swell drops to under 3ft, the period shortens, and the wind is mostly cross-onshore or onshore. The combined energy stays below 300, often in the weak double digits. There’s a little bump on Sunday, July 19th, with 4ft to 5ft SSE swell and a 13-second period, bringing energy up to moderate (481-520), but the wind is onshore and cross-onshore, keeping conditions poor. The following Monday, July 20th, has a similar size but with a moderate SE wind, so don’t expect much.

The tail end of the run, into the third week of July, looks very ordinary. Tuesday, July 21st, has a small 5ft S swell in the morning, but the wind is light cross-onshore, so it’s marginal. Wednesday, July 22nd, the morning is tiny with 2ft and glassy conditions, but it’s barely surfable. After that, we’re back to flat, weak junk until Friday, July 24th, when a 4ft S swell with a 12-second period shows up, but again, the wind is cross-onshore.

So, to sum it up: if you’ve got a window, make it Sunday morning, July 12th. That’s the one. The rest of the 16 days is mostly waiting for the next pulse. It’s a pretty typical run for this spot—the surf just doesn’t stay good for long, so you’ve got to jump on it when it’s there.

Rusty.
