The Lowdown
Alright folks, Rusty here. Let’s get into it.
Alright, we’re looking at a pretty quiet spell ahead for Hanamizu River. The first week or so is mostly flat or just tiny, with a lot of messy wind and poor conditions. There’s a real gap here with nothing worth paddling out for until we get into early August. The first real glimmer of hope shows up around Monday the 3rd of August, but even then, it’s a slow build.
The best of what we’ve got lands on Thursday the 6th of August. Thursday morning is your standout. The swell is tiny, only 2ft, but it’s coming from the ESE with a period of 15 seconds – that’s proper groundswell energy. That long period means the waves will have some shape to them, even at that size. The wind is glassy offshore from the SE, so the surface will be clean as a whistle. The combined energy is moderate (190), so it’s not a powerhouse, but for a little sandbar wave, it’ll be fun. Just keep in mind it’s a beach setup, so that long period might make the waves a bit straight, but with those conditions, you’ll get some fun little runners.
The water temperature is about average for the time of year, so no surprises there.
The rest of the fortnight is a write-off, with onshore winds and tiny, weak energy. The swell tries to pick up a little on the 9th and 10th, hitting 4ft, but the period is short (5-6 seconds) and the wind is cross-onshore, so it’ll be a choppy, bumpy mess. That’s more kite-surfing territory than anything for a paddle board.
So, if you’re keen, circle Thursday morning the 6th of August for a chance at a few clean, small waves. Otherwise, it’s a long wait.
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.
