Hanamizu River Surf Forecast and Surf Report

Alright, weather looks a bit small and messy to start, but things are shaping up for some big clean action in the second week. Let’s get into it.

First up, straight from the start of the period on Sunday the 30th of August, we’ve got flat to tiny waves at the Hanamizu River (beach/sandbar). The water temp is running about 1.0° warmer than normal for this time of year, coming in at 28°, so a degree or two toastier. Not much surf to get excited about though. From Sunday afternoon through to the middle of the first week, swell is hanging between 1ft and 2ft, and it’s mostly from the SSW, which is not the optimum direction (SE is) for this spot. Winds are often cross or onshore, and the energy is weak. We’re looking at combined swell energy values in the 21 to 68 range. Basically, for the first six days, everything’s a no-go.

The poor run drags on through to the 6th of September, Sunday morning, when we finally see a pulse of energy hit – still only 3ft from SSE, but the period jumps to 13 seconds. The combined energy leaps to 395, and there’s a cross-off wind from the NNE with clean conditions. That’s the first hint of something decent, but combined swell energy is only moderate, so it’s more of a hopeful sign than a standout. The wind cleans it up though. You’ll get some smaller clean lines, but not a day to clear the diary.

Now, hold on – the real standout is coming. On Wednesday the 9th of September, the Hanamizu River sees a proper pulse. Morning session gets an 8ft SSE swell at 13 seconds, with clean cross-off wind from the NNE at 15 km/h. Combined swell energy hits 2215 – that’s strong wave energy. The swell direction is SSE, which works for the optimum SE direction. Water temp is going to be similar, around 28°, and winds are light and offshore. That’s the best call of the whole run. But at 8ft, this is for experienced surfers only – beginners stay out of the water. The river mouth should handle this well, with that long period groundswell. Thursday the 10th also has size – 8ft morning, 6ft afternoon – with clean cross-off wind again, but the morning has strong winds at 25 km/h, so Wednesday morning is the winner.

After that, it drops back from Friday the 11th onward into smaller stuff, below 4ft through the 14th, and the conditions turn questionable again with onshore light rain on the final days.

So if you’re picking one window, it’s the morning of Wednesday 9th September. That’s your moment.
