Hanamizu River Surf Forecast and Surf Report

Alright, surfers, Rusty here. Let’s get into it. The long-range models are showing something for the Hanamizu River mouth, but it’s going to take a while to get going. The first week is looking pretty average, but there’s one standout window if you’ve got the patience and the skills. Water temp is running a touch warmer than usual for this time of year, sitting at 82°F, which is nice.

The surf starts out pretty weak. Monday and Tuesday the 3rd and 4th are looking marginal, with small, clean-ish waves in the morning but nothing to get too excited about. The swell energy is still weak to moderate. The wind is cross-off but a bit fresh, so it’s not going to be perfect.

We’ve got a bit of a gap through the middle of the week with no real quality. Wednesday the 5th sees a jump in size to 8ft, but the swell direction is a bit off and the energy is moderate. It’s still pretty cross-shore and choppy, so not the pick. Thursday the 6th is similar size, but the winds get messy – onshore Thursday afternoon – so you’d be fighting it. Honestly, Thursday afternoon is not worth your time.

Now, here’s where it gets interesting. Friday, August 7th is your standout. The morning looks excellent for experienced surfers. We’re looking at a solid 8ft of south swell, with a long 16-second period. That’s proper groundswell, and it’ll be wrapping into the river mouth. The wind is light, cross-off from the NNE, which should keep it glassy and clean. The energy is strong. This is the best combination of size, period, and wind we see in this whole outlook. Because it’s over 8ft, this is only for the experts out there – the beginners need to give this one a miss. This break is a beach/sandbar setup, so the long-period swell might make it a bit straight, but with that offshore wind, it could be worth the paddle.

The weekend is a step down. Saturday the 8th is still rideable with 6ft of south swell, but the wind turns more cross-on, making it a bit lumpy. It’s not terrible, but it’s a clear drop-off from Friday.

After that, the surf fades fast. From Sunday the 9th onwards, we’re looking at a real dry spell. Swell drops below 3ft pretty quickly and the energy just dies. For the rest of the 16-day window, the river mouth will be pretty flat and not worth the drive. The forecast looks poor for over a week, from the 9th through the 18th. It’s the kind of run that happens sometimes, but the good news is that this spot is generally fairly consistent, so a blank run like this doesn’t usually last forever.

So, in short: mark your calendar for the morning of Friday, August 7th. That’s the one. Get out there if you’re experienced and enjoy the clean 8ft groundswell. Otherwise, keep the board in the car for a while.

Rusty.
