Hanamizu River Surf Forecast and Surf Report

G’day, Rusty here. Let’s talk about Hanamizu River.

We’ve got a bit of a mixed bag over the next couple of weeks. The first few days kick off with some solid, clean surf, but then it really drops off into a long, flat spell. The real standout is Monday the 7th – that’s your best bet by a long shot. Water temp is sitting at 82°, which is a touch warmer than normal for this time of year, so you’ll be comfortable in a spring suit or just boardies.

Monday, 7th September – This is the one to circle. Morning starts with heavy rain, but the wind is a light WNW cross-off at 6 mph, keeping the 7ft S swell (9-second period) super clean. The combined energy is moderate at 739, and the waves are packing a punch. It’s a beginner-friendly setup, so it’s great for everyone. By the afternoon, the swell jumps to 10ft from the S with the same 9-second period, and the energy rockets up to 2076 – that’s strong wave energy. The wind stays light and cross-off. This is big, powerful surf, and it’s excellent for experienced surfers only. Beginners, stay out of the water in the afternoon – it’s going to be a heavy one.

Tuesday, 8th September – Still decent. Morning brings cloudy skies and glassy conditions with a 3 mph ENE wind. The swell drops to 5ft from the S, period 9 seconds, and the energy is moderate at 527. It’s clean, fun, and easy. Afternoon sees heavy rain but it stays glassy with a 4ft SSE swell. Still good, but nothing like Monday.

Wednesday, 9th September – It starts to get ordinary. Morning is a cross-shore wind from the SW at 9 mph, with a 5ft SSW swell. It’s a bit choppy and marginal. Afternoon has a risk of thunderstorms, and the swell bumps up to 7ft from the S, but the wind is light and cross-shore, creating some ripples. Not great.

Thursday, 10th September – This is where it fades. The swell drops to under 3ft, and the wind picks up from the NNE at 9 mph. The waves are small, weak, and ordinary. The energy is just 117 in the morning and 84 in the afternoon. It’s surfable but not worth getting excited about.

Friday, 11th September through to Saturday, 19th September – This is a big gap. From Friday the 11th all the way through to Saturday the 19th, the surf is poor. Swell heights are barely 2ft or less, period is short, and the combined energy rarely gets above 100. It’s flat, weak, and messy. Honestly, there’s nothing to recommend here for a paddle surfer. The setup is more interesting for kite surfing than anything else during this stretch.

Sunday, 20th September to Monday, 21st September – We start to see a new pulse, but it’s still not good. The swell is from the ESE with a very long period of 16 to 19 seconds, but it’s small – under 3ft. The energy is moderate (341 to 540), but the wind is cross or cross-on, ruining the shape. The long period will make these waves break too straight for the beach setup, so it’s not a winner.

Tuesday, 22nd September – The final day of the forecast shows a bit more size with 4ft from the ESE, period 18 seconds, and the energy is strong at 764. But the wind is a moderate NNE breeze at 16 mph, creating a cross-off but still messy. It’s marginal, and with the long period, it’s not ideal for the beach break.

So, to wrap it up: Monday the 7th is your standout. The morning is perfect for everyone, and the afternoon is for the pros. After that, you’ve got a long, flat run until the 22nd, and even then it’s not great. Keep an eye on the forecasts, but for now, make the most of that Monday.

Rusty.
