The Lowdown
Alright folks, Rusty here. Let’s get into it.
Right off the bat, things are looking pretty quiet for Hakashita. This is a reef break that’s known for being inconsistent, and that’s exactly what we’re seeing. We’ve got a few days of small, sloppy surf before a massive pulse of energy arrives later in the week, but it comes with some serious caveats.
The best of the bunch, and the real standout in this forecast, is the morning of Tuesday the 25th of August. We’ve got a solid 15ft swell out of the ESE, with a very long period of 16 seconds. That’s groundswell with serious power, and combined swell energy is enormous at 10672. The wind is a clean cross-offshore from the NNE, which should keep the surface nice and clean for the experts. This is a big, powerful setup for Hakashita, but the swell is over 8ft, so this is strictly for experienced surfers only. The long period will also mean the waves might be a bit too straight for this reef, but the quality of the energy is undeniable.
Before that, we have a slow start. Thursday morning the 20th of August is offering a tiny 2ft east swell with a short 8-second period and cross-shore wind. Combined energy is a weak 77. It’s poor. Friday morning the 21st of August is the first real glimmer of hope with a 3ft south swell and glassy conditions. The combined energy is a moderate 215, and the wind is glassy, making it a clean, small wave option. That’s the best early window.
The huge swell on the 25th is followed by some messy conditions. By Wednesday the 26th, we’re looking at 18ft of ESE swell, but the wind is a near gale at 34 mph. That’s dangerous and not worth paddling out for. It’s more of a kite day.
After that, we get a drop in size. The morning of Thursday the 27th of August has a 5ft ESE swell, very clean with glassy wind from the west. Combined energy is moderate at 522. That’s a nice, clean option for intermediate surfers. Then Friday morning the 28th of August is another clean, small day with a 4ft swell and calm wind.
The second week drops off significantly. Into late August and early September, we’re back to small, weak swells between 3ft and 5ft, mostly from the east or southeast, with periods around 8-10 seconds. The winds are mostly light cross or cross-off, but the energy is well under 500. The morning of Monday the 31st of August has a 6ft ESE swell with a short 7-second period and clean cross-offshore wind, but the period is too short for any real power.
Water temperature at Hakashita is a warm 84°, about average for this time of year. Nothing strange there.
So, to wrap it up: the standout is Tuesday morning the 25th of August for experts only. If you’re an intermediate, look at Friday morning the 21st of August or Thursday morning the 27th of August. The rest of the window is mostly small and average.
Stay safe out there.
Rusty.

Information about the Hakashita Surf forecast
The above surf forecast table for Hakashita provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hakashita can be found by selecting the local surf guide option on the grey menu. Our Hakashita 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 (Hakashita) 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 Hakashita 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.
Hakashita is 14 km (9 miles) from Takanabe. If you plan a holiday in Kyu Shu, look for hotels and other accommodation in Takanabe. Takanabe has rooms for a wide range of budgets as well as car hire and transport links.
