Hanamizu River Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a proper look at what’s coming down the pipe for Hanamizu River.

First off, the water’s a touch warmer than normal for this time of year at 82°.

Now for the surf. Starting Monday September 7th, we’ve actually got a bit of a gem to kick things off. That Monday afternoon brings in a 7ft S swell rocking a 9-second period, and combined wave energy is sitting at 679 – moderate stuff. The real kicker? Glassy conditions with a whisper of a north wind at just 3 mph. That’s clean as a whistle. Hanamizu River is a beach/sandbar, fairly exposed, so this S swell will wrap in nicely. The swell direction matches up with what this spot likes. It’s a beginner-friendly wave size, so perfect for a long session without getting hammered. Expect very good surf conditions – this is the standout of the whole outlook.

Tuesday morning the 8th is still worth a paddle, but it’s a step down. Swell drops to 3ft from the SSW at 10 seconds, energy down to 275 – still moderate. Glassy early with ESE winds at 3 mph, so it’ll be clean but small. By Tuesday afternoon the wind swings southerly and goes cross-on at 6 mph, and the quality tanked. Not great.

Wednesday the 9th is a write-off. Swell bumps up to 5ft – 6ft from the S, but with a 16 mph cross breeze and then cross-off winds, it’s messy. Combined energy jumps to 454 – 473, but the wind kills it. Poor conditions.

From Thursday the 10th right through to the end of the first week, it’s a long flat spell. Swell drops under 3ft, energy falls below 200, and by Friday we’re scraping at 2ft with energy in the 30s and 40s. The wind stays mostly clean or glassy, but there’s simply no wave to ride. That gap of several days of no good surf runs from Thursday the 10th all the way through to the end of the 16th.

Now, we do see a flicker of life on Monday the 14th. That afternoon shows a 2ft SE swell with a 10-second period, glassy wind, and energy of 80. Surfable but very ordinary – not worth getting excited about.

Then, another dry spell hits until we get to Tuesday the 22nd of September. This one’s interesting but with a big caveat. Tuesday morning brings a 6ft SE swell at a very long 18-second period. The combined energy is massive – 2302 – this is strong wave energy. The wind is light and cross at 6 mph, so not utterly blown out. But this is a long-period groundswell, and at a beach/sandbar setup like Hanamizu River, those long lines can break too straight and be tricky to manage. The rating’s marginal, and it’s more of an expert wave at that size in a spot like this. Tuesday afternoon the swell pushes to 7ft, energy hits 2960, but the cross-on wind is 12 mph creating a chop. Not clean. So it’s a promising but uncertain call, and far out – over a week away – so don’t bank on it yet.

Bottom line: Monday the 7th afternoon is the real deal. Clean, glassy, fun-size swell, and Hanamizu River will be working. The rest is either flat or compromised. If you’re after something way out there in the long range, Tuesday the 22nd morning could deliver big waves for experts, but it’s a gamble with that beach setup and cross wind.

Stay stoked and keep an eye on the sky.

Rusty.
