Hanamizu River Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s break down Hanamizu River for the next couple of weeks. Gonna be honest—there’s a big lull at the start, and we’re waiting a while before anything decent shows up.

Overall, it’s a tale of two halves: the first week is mostly weak and messy, then we get a couple of days with proper size and clean conditions before it all fades again. The water temp is about 75°F, which is just under a degree cooler than usual for this time of year—nothing wild, just a little crisp.

Here’s the day-by-day.

Monday 6th July – Tiny waves, barely 3ft from the SE, period a short 7 seconds. Energy is low at 176. Light rain and a light breeze, but Monday afternoon turns glassy with 3ft and energy up to 199. It’s surfable but real ordinary. Not worth suiting up.

Tuesday 7th July – Swell drops to 2ft Tuesday morning, period jumps to 15 seconds—longer period groundswell. Combined energy hits 289, but wind is cross-shore from the NE at 15 mph. Not clean. Afternoon has 3ft with a 15-second period (energy 454) and light offshore SE wind at 5 mph, but the waves are still marginal. Nope.

Wednesday 8th July – Now we’re cooking. Wednesday morning brings 5ft swell from the SSE with a very long 17-second period. Combined energy jumps to 1549—moderate energy now. Wind is glassy offshore from the ESE at 5 mph. This is the first real standout. The swell direction is a touch off the optimum SE, but with that period and clean wind, the waves should have some punch. That’s 5ft at 17 seconds—powerful, not for beginners. The long period can make beach breaks a bit straight, but still a solid option.

Thursday 9th July – Swell holds around 6ft to 6ft from the S, still long period (15 seconds). Combined energy 1300–1441, moderate. Morning has offshore SE wind at 5 mph, but conditions are unclear. Afternoon gets cross-onshore from the S at 15 mph, choppy. Marginal.

Friday 10th July – Size bumps to 7ft Friday morning, with a 16-second period from the S. Combined energy 2207—strong. Wind is offshore from the SSE at 10 mph, light breeze. This is the other standout. 7ft is significant—only for strong surfers. The long period means powerful waves, and at a beach break, sets will be thick. Afternoon gets messy with S wind at 20 mph, cross-onshore. Get out early.

Saturday 11th July – Swell holds 7–7ft from the SSW, period 16–17 seconds. Energy peaks at 2574 in the morning, but wind is cross-onshore from the SSE at 15 mph. Afternoon is worse with 25 mph winds. Blown out.

Sunday 12th July to Tuesday 21st July – After Saturday, it’s a steep drop. Sunday has 4ft, but cross-onshore. By Monday the 13th, we’re down to 2ft. From Sunday 12th through to Monday 20th, it’s mostly poor surf—small waves, cross-onshore winds, energy dropping below 100 at times. There’s a glassy moment on Tuesday 14th with 2ft and 11 seconds, but the swell is tiny. Not worth it. On Saturday 18th afternoon, a slight bump to 4ft with 12-second period and 602 energy, but it’s still poor conditions.

Beginners should sit out Wednesday 8th and Friday 10th—5ft and 7ft are too big. Experts, Friday 10th morning is the best of the whole forecast: 7ft, long period, clean offshore wind. Wednesday 8th morning is also a good call. Crowds are marked as “sometimes,” so expect a few heads out, but nothing too crowded.

That’s the run. First week is a dud, but Wednesday 8th and Friday 10th are your windows. Keep an eye on the forecasts—things can change.

Stay stoked,
Rusty
