The Lowdown
Alright, Rusty here again, this time in feet and miles for the imperial crew. Let’s break down Hakashita. It’s an exposed reef that doesn’t break all that often, so when it’s on, you want to be there. Water temp is around 83°, right on the seasonal average.
First few days are dead. August 21st and 22nd have tiny weak swell with onshore wind—totally flat and ugly. August 23rd is no better with a messy cross-shore. So there’s a gap until things turn around.
Monday August 24th morning is the first real option. Small 2ft swell from the SE, clean with a light cross-offshore breeze. Combined energy is 607, which is moderate, but it’s surfable. The afternoon picks up to 7ft from the SE with a very long 17-second period, energy jumps to 2557, strong. Conditions are a little bumpy though.
Tuesday August 25th is serious. Swell hits 15ft from the SE, 16-second period. Combined energy is huge—9482 in the morning, 11171 in the afternoon. But the wind is cross-shore and moderate, so it’s choppy. Only for experts. Beginners, stay on the sand.
Wednesday August 26th is a beast. Morning swell 18ft from the SSE with a strong cross-onshore wind at 25 mph. Combined energy is 20492—very strong, but completely blown out and way too big for Hakashita. This is kite-surfing territory.
Thursday August 27th is still big (12ft) but onshore, poor conditions.
Best of the bunch is Friday August 28th morning. Swell 12ft from the SSE, 9-second period, combined energy 2080 (strong), but the wind is light and cross-offshore from the NE. Clean conditions. This is excellent for experienced surfers. The reef will be handling it beautifully.
Saturday August 29th drops right back to 5ft with onshore wind—poor.
Sunday August 30th and Monday August 31st mornings are small and clean. Sunday has 3ft from the ESE, glassy, 8-second period, combined energy 273 (weak). Monday similar at 4ft, glassy, 10-second period. Good for logs.
Then into September: Tuesday the 1st and Wednesday the 2nd mornings are clean with light cross-offshore wind, swell around 5ft to 5ft from the E, 11-second period, combined energy moderate (684-724). Fun for everyone. The afternoons get a bit onshore, so mornings are better.
Thursday September 3rd morning is smaller (3ft) but clean.
Friday September 4th afternoon is another standout. Swell 5ft from the SSE, 13-second period, combined energy 1104 (strong), with light cross-offshore wind. Clean and excellent for experienced surfers.
Saturday September 5th gets onshore and messy, so it’s marginal at best.
So if you want the real deal, hit Friday August 28th morning and Friday September 4th afternoon. The September 1st and 2nd mornings are also great fun without the heavy commitment.
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.
