The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a bit of a slow start on the table for Hakashita. The first few days are looking pretty flat and messy, so don’t get too excited early on. From Tuesday the 18th through to Thursday the 20th, the swell is small – around 2ft to 3ft – and the wind is mostly onshore or cross, which is just making it a bit of a write-off. The water temperature is sitting at 84°F, which is about average for this time of year, so nothing to worry about there.
The first real sign of life shows up on Friday morning, the 21st of August. The wind goes glassy, and we get a 4ft S swell creeping in. The combined energy is moderate at 334. It’s not huge, but it’s clean. That morning session is the pick of the first week, but it doesn’t last long – the afternoon goes onshore again.
We then hit a bit of a dry spell from Saturday the 22nd through to Monday the 24th. The swell stays small, winds are messy, and the energy is weak to moderate. Not worth paddling out for unless you’re really keen.
Now, things get interesting from Tuesday the 25th of August. A long-period SE groundswell starts to fill in. The period jumps to 16 seconds, and the combined energy is strong at 311. The swell is still only 2ft in the morning, but it builds to 5ft by the afternoon. The wind is light cross-on, so it’s okay but not perfect.
The standout window is Wednesday the 26th of August through to Saturday the 29th. This is the big one. Wednesday morning the 26th sees glassy conditions with an 8ft SE swell at 14 seconds. The energy is very strong at 2775. This is excellent surf, but at 8ft, it’s getting into expert territory. Thursday the 27th is even better – glassy again, 10ft SSE swell, period 15 seconds, and energy at 3996. That’s a serious groundswell. For a reef break like Hakashita, the long period will create some nice, lined-up waves, but it can also make them a bit straight and fast, so keep your wits about you.
Friday the 28th of August is the absolute peak. Glassy conditions, 13ft SSE swell, period 16 seconds, and energy cranking at 7410. This is exceptional surf, but only for expert surfers. Saturday the 29th is still pumping with 13ft swell and glassy morning conditions, though the energy drops a little.
After that, the swell slowly backs off into the first few days of September. Sunday the 30th and Monday the 31st still have solid 7ft to 8ft S and ESE swells, but the wind picks up and becomes cross or cross-on, making it less clean. Tuesday the 1st of September and Wednesday the 2nd see cleaner cross-offshore winds, but the swell drops to around 8ft to 8ft, and the period shortens. The energy is still strong, but it’s not the same quality as that late August run.
If you’re looking for the best, the Thursday the 27th and Friday the 28th of August are the ones to circle. Glassy, big, powerful groundswell, but it’s for experts only. If you’re intermediate, aim for the Wednesday morning the 26th or Saturday the 29th morning when the swell is still big but a bit more manageable.
Rusty, signing off.

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.
