The Lowdown
Alright folks, it's Rusty here. Looks like we're in for a pretty flat spell at Hanamizu River. The whole 16-day window is a tough one, with barely a ripple worth getting wet for.
Right off the bat, we've got a long stretch of nothing. From the start of the forecast on Wednesday the 22nd of July, right through to the morning of Sunday the 2nd of August, there's just no real surf to speak of. We're talking tiny swells, all under 3 ft, and mostly riddled with cross-onshore breezes. The water temp is sitting at a pretty normal 80°, so at least the wait won't be cold.
The first tiny glimmer of hope shows up on the morning of Sunday the 2nd of August. The wind swings around to a cross-offshore from the NNE, which should clean things up a bit. The swell comes from the ESE at 2 ft, with a period of 16 seconds. That’s a long period, which means it’s got some energy behind it, but with such a tiny height it'll just be small, clean lines. The combined energy is 156 (moderate) for that morning, but it's still only a 1/10. It's a "surfable waves but very ordinary" kind of day. If you're desperate for a paddle and a few knee-high peelers, it's your only real look.
Monday the 3rd of August sees a similar small bump of ESE swell at 2 ft, with a long 18-second period. Energy picks up a bit to around 185-197 (moderate) but it's all cross-onshore again, so that window closes fast.
Honestly, that's about it. Nothing stands out as a proper session. The whole forecast is just one long, flat gap with a couple of very marginal mornings. It's one of those periods where you're better off doing something else and checking back later. Forecasts can change, but right now, it's a hard pass.
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.
