The Lowdown
Alright, Rusty here, and I’ve given Hakashita’s forecasts the once-over. Here’s how it shakes out in feet and degrees.
Water temp is 83°, right where it should be for this time of year. This is a reef break that doesn’t fire all that often, so when it lines up, you take notice.
Thursday 13th is a bust – knee-high south swell and crummy cross-onshore wind. Friday 14th morning goes flat and glassy, but it’s tiny. Saturday 15th morning is the first real sign of life – glassy conditions with a 2-3ft east swell, energy picking up. Sunday 16th morning and afternoon keep that glassy, clean vibe with the east swell holding.
Monday 17th morning is the first winner: glassy, 4ft of ESE swell at 10 seconds. Clean, lined-up waves and zero wind.
Then it gets messy for a couple of days.
Now here’s the big news. Sunday 23rd August morning: a proper groundswell hits – 5-6ft from the SE at 16 seconds. That’s a ton of energy (1528), and with a light offshore wind, it’s clean and powerful. The afternoon doubles down at 7-8ft and glassy.
Monday 24th August morning is the one: 11-12ft of SE swell at 17 seconds, glassy conditions, and energy readings over six thousand. That’s for experts only. Tuesday 25th morning is even bigger – 13ft-plus (6810 energy), still glassy. Wednesday 26th morning is another 11-12ft morning of pure glass.
That long period (15-17 seconds) means the reef will handle it beautifully, but it’ll be a handful.
It tails off from Thursday 27th morning (8ft and glassy) down to nothing by Friday 28th.
The undeniable standout is Monday 24th August morning – 11-12ft, glassy, screaming SE groundswell. Pure power for the brave. For a more normal-size session, Monday 17th August morning at 4ft and glassy is the pick. The crowds could turn up for the big days, but that’s the price of a perfect reef.

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.
