Alright folks, Rusty here. Let's have a look at what the next couple of weeks are serving up for us.
Right off the bat, it's a slow start. The first real glimmer of something surfable doesn't show up until Tuesday morning the 7th, and even then it’s a bit of a tease. We’re dealing with a pulsing, long-period groundswell from the SSE, but it’s wrapped in some less-than-ideal conditions at Hanamizu River.
Tuesday morning the 7th sees a small 2ft SSE swell, but the period is a solid 15 seconds. That's proper groundswell energy. However, it's coming in with a cross-shore NE wind at 9 mph, so it’ll have a bit of chop on it. The combined energy is a modest 289, hinting at just weak to moderate push. Not much to write home about, but it’s something.
The real interest starts to build on Wednesday morning the 8th. The swell picks up to 5ft from the SSE, still with that lovely 16-second period. The combined energy jumps to a much healthier 1094, which is solid moderate to strong energy. The wind is light out of the ESE at 3 mph, light cross-onshore but with just small wind ripples. It’s still going to be a bit lumpy but that's about as good as it gets for the window. Thursday morning the 9th is another option with a clean onshore wind from the SSE at 6 mph, swell at 5ft and a 14-second period.
Now, if you’re an experienced surfer and can handle some size, Friday morning the 10th is the standout. Swell pushes up to 6ft from the S with that long 16-second period. The combined energy screams through at 1565 – that’s proper power. The wind is light cross-onshore from the SSE at 6 mph, so there’ll be some texture, but the energy is there. It’s a solid size, getting near the top end for a beginner, so keep that in mind. The direction from the S is close to that optimum SE direction the river likes, so it should wrap in okay.
Saturday the 11th holds size but gets windier and uglier. 7ft from the SSW early with a 17-second period is a beast of a swell, but that S wind at 9 mph makes it a choppy mess. By the afternoon, it's over 8ft and with 12 mph winds, it's expert-only and not very inviting.
From Sunday the 12th onwards, it’s a steady fade. The swell drops, the periods shorten, and the winds stay cross-onshore or just messy. We go through a long stretch from Sunday the 12th afternoon right through to Tuesday the 21st where everything is rated as poor. There’s a brief flicker on the morning of Wednesday the 15th with a 3ft SE swell, but it’s still weak. The models show a bit of clean air coming in on Tuesday the 21st and Wednesday the 22nd, with offshore NNW and NNE winds, but the swell is tiny – 1ft and 2ft. That’s barely a ripple.
So, the best bet in this whole outlook is Friday morning the 10th. It’s got the best combo of size, long-period power, and the least offensive wind. Thursday morning the 9th is a solid backup for a cleaner, smaller wave. Everything else is either too small, too windy, or both.
Stay patient, lads. The ocean will give us something soon.

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.
