Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Hanamizu River over the next couple of weeks. It’s a bit of a slow burn, so let’s get into it.
The water’s sittin’ at 75°F right now, which is just a touch cooler than average for this time of year – nothin’ to write home about, but you’ll notice it.
The opening days are pretty marginal, to be honest. We’ve got a long-period groundswell from the SSE rollin’ in on Tuesday afternoon, July 7th, with waves around 3ft. Problem is, the wind is light onshore, and the combined energy is only moderate at 447. Not exactly pumpin’. Wednesday the 8th sees the swell bump up a bit – 5ft in the morning, with a 16-second period from the SSE. The energy climbs to 1094, which is solidly moderate, but the wind is still onshore. It gets a little messy in the arvo as the wind swings S and picks up. Thursday and Friday are more of the same – onshore flow and that cross-on breeze messin’ up what could be a clean wave.
Now, into the weekend, we see the swell start to push up a little more. Saturday morning, July 11th, we’re lookin’ at 7ft from the SSW with a 17-second period. That’s a proper groundswell, energy is at 2485 – that’s strong energy, you’ll feel it. But here’s the rub: it’s still cross-on with a moderate breeze. For a sandbar setup like this, that long period swell and onshore wind is gonna make for some tricky, bumpy waves. This is more in the expert zone too – over 8ft is a big ask for the average punter. The afternoon gets worse.
The best chance for a half-decent session looks like Sunday morning, July 12th. The swell drops back to a more manageable 5ft from the SSW, still a solid 16-second period, and the wind backs off to a light cross-on breeze. The energy is still moderate at 1211. It won’t be perfect, but it’ll be the cleanest of a rough bunch. Don’t expect a crowd – it’s inconsistent here and the conditions aren’t gonna bring out the masses.
By Monday the 13th, the surf drops off a cliff. We’re looking at a week of tiny, weak waves with poor conditions. There’s a brief pulse of 5ft from the SSE on Wednesday, July 15th, but the wind is already on it, choppin’ things up. After that, it’s flat city – consistent energy readings in the teens and twenties, with nothing but onshore breeze and garbage surf until we run out of forecast. That’s a solid 7 to 8 day gap of nothin’ to ride.
So, for the entire 16-day window, the only real standouts are Saturday the 11th if you’re a masochist and Sunday the 12th if you’re patient. The swell’s there, the direction’s okay for the SE optimum, but the wind is the villain in this story. It’s a beach break with onshore flow, and for the bigger days, it’ll be more interesting for the kite crew than paddle surfers.
Stay tuned, though – forecasts change, and it doesn’t stay this quiet forever.
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.
Hanamizu River is 1 km (1 miles) from Ninomiya. If you plan a holiday in Kanagawa, look for hotels and other accommodation in Ninomiya. Ninomiya has rooms for a wide range of budgets as well as car hire and transport links.
