Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

Honestly, I gotta be straight with you. This is a pretty grim stretch for Hanamizu River. The whole 16-day window is a total write-off for any decent surf. We’re looking at a solid run of poor surf conditions with no real standout days. The first surfable moment pops up on Monday afternoon, July 13th, but it’s nothing to get excited about.

Monday afternoon, July 13th, we get a tiny pulse of 3ft swell from the SSW, with a period of 12 seconds (groundswell). The water is a bit colder than normal at 76°. The combined energy is moderate (216). The wind is glassy though, so it’ll be clean. But the waves are just too small and ordinary to call it a session. The score is a 1 out of 10 – it’s just not worth paddling out for.

After that, it’s a long, dry spell. From Tuesday morning, July 14th, all the way through to Sunday, July 26th, the forecast is basically a sea of zeros. The swell drops to 2ft or less, the wind is mostly cross-onshore or onshore, and the combined energy is weak – often under 100. It’s a long run of poor surf conditions, with some days showing choppy or messy wind. There’s a bit of a bump on Wednesday afternoon, July 15th, with 3ft from the S and energy hitting 117, but the cross-onshore wind ruins it.

The only real flicker of something interesting is way out on Monday, July 27th, more than a week away. The afternoon shows a 3ft swell from the S with a long period of 13 seconds, and the combined energy jumps up to strong (448). But the wind is moderate cross-onshore, and the wave comment is still “poor surf conditions.” Tuesday, July 28th, is cleaner with a cross-offshore wind, but the swell is still only 3ft from the S.

So, the bottom line is, there’s nothing here. No standouts, no good windows. If you’re a beginner, the swell never gets above 3ft, so it’s not too big, but the quality is so bad it doesn’t matter. With the wind and small size, this setup might actually be more interesting for a kite surfer than a paddle surfer. It’s a blank run, plain and simple. Forecasts can change, but for now, I’d hang the board up and wait for a better call.

Rusty.

Information about the Hanamizu River Surf forecast

The above surf forecast table for Hanamizu River provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hanamizu River can be found by selecting the local surf guide option on the grey menu. Our Hanamizu River surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Hanamizu River) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Hanamizu River may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
