The Lowdown
Alright, let’s switch it over to feet and Fahrenheit for the imperial heads.
First up, Hakashita. This reef’s been pretty quiet to start. We’ve got small, weak east swell rolling in, around 2 to 3 feet, with periods between 8 and 10 seconds. The combined energy is weak to moderate (229 to 148), and the wind’s mostly onshore or cross-on, so it’s choppy. Not much to get excited about the first few days – just a couple glassy windows on Monday and Tuesday mornings where you might find a waist-high dribbler if you’re keen. It’s inconsistent here, so that’s normal.
Then things shift around Thursday the 20th. The swell direction swings south, and the energy bumps to 266 on Thursday morning, but the wind’s still cross or onshore. Not clean.
Friday the 21st is where we get a pulse. A 6 foot south swell with a 10-second period rolls in, and the energy jumps to 670 – moderate-to-strong. The wind goes glassy early. That’s the first proper window. Expect very good surf, but it’s a reef, so watch the low tide. Crowds are sometimes.
Saturday the 22nd morning stays clean – another glassy session with a 4-foot south swell (322 energy). Good surf. Afternoon gets blown onshore.
After that, the south swells fade. Sunday the 23rd and Monday the 24th are mostly poor or tiny, under 2 feet.
Now the real standout builds through the second week. Tuesday the 25th of August – this is a beauty. A 4-foot southeast groundswell, period stretching to 14 seconds, and the energy hits 643. Glassy early. That’s the best quality we’ve seen. The long period will wrap nicely into this reef.
But the swell keeps building. Wednesday the 26th and Thursday the 27th bring 5 to 10 feet of southeast swell, periods around 15 to 16 seconds, and the energy goes from strong (1594) to very strong (3465). The wind on Thursday is cross-offshore – clean faces – but these waves are for experts only, especially the 8 to 10 foot sets. It’s powerful.
Then the wind destroys it. Friday the 28th has 30 to 35 km/h winds, choppy and lumpy. Saturday the 29th is a washout – heavy rain, severe gale winds at 75 km/h, and a huge 13-foot swell blown sideways. Energy over 7268 but totally unsurfable. That’s kite-surf territory.
Sunday the 30th stays blown with 16-foot+ swells.
The final standout lands on Monday the 31st of August. The wind goes glassy early, the swell drops to a still-big 13 feet from the east, with a 15-second period. Energy is 7322 – very strong, but the conditions are exceptional. That’s for experts only. Heavy, powerful, and clean. If you’re good enough, circle that date.
Water temp is 83°F, about average for this time of year.

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.
