Updates in hr min s Forecast update imminent
Hey, Rusty here. Hanamizu River’s got a bit of a mixed bag over the next 16 days. The first week’s mostly marginal — onshore breezes and small to moderate swell, nothing that’ll get your heart racing. But there’s a real bright spot way out on July 22nd that’s worth circling.
Let’s start with this week. Tuesday morning (July 7th) brings a 2.3ft SSE groundswell at 15 seconds, but the NE cross-offshore wind keeps things clean — still, the water temp is about average at 74.8°, and the overall energy’s weak (287). The afternoon goes onshore with SE wind, making it messy. Wednesday morning (July 8th) sees a 4.6ft SSE swell, 16-second period, but wind is onshore from the ESE, so not clean. Afternoon gets cross-onshore and choppy. Thursday (July 9th) morning has 4.9ft S swell at 14 seconds, again onshore from SSE — marginal. Friday (July 10th) morning jumps to 6.2ft S swell, 15 seconds, with light cross-onshore wind, so some shape but still textured. Saturday (July 11th) morning hits 6.6
Short Range ForecastMostly dry. Warm (max 26°C on Tue afternoon, min 22°C on Tue night). Wind will be generally light. | Days 4-6 Weather SummaryLight rain (total 4mm), mostly falling on Sat night. Warm (max 28°C on Sun afternoon, min 23°C on Fri night). Wind will be generally light. | ||||||||||||||||||||

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.
