The Lowdown
Alright, this is Rusty, and I’m lookin’ at a tricky outlook for Hakashita. It’s a reef break, exposed to the swell, and it’s an inconsistent spot which means we need to be patient. The water temp is sittin’ right around 83°F, which is just about what you’d expect for this time of year, so nothin’ unusual there.
The first week is a bit of a write-off, to be honest. We’ve got a run of poor surf conditions from Monday the 17th right through to Wednesday the 19th. The waves are small, around 2ft to 3ft from the east, with a short period of 8 to 9 seconds. The wind is all wrong too – cross-onshore and occasionally cross-shore – makin’ for some choppy, bumpy faces. The combined energy is weak, sittin’ between 115 and 197 (weak energy). There’s really nothin’ to get excited about.
Thursday the 20th morning shows a glimmer of hope. The swell picks up a bit to 3ft from the SSE with a 10-second period, and the wind goes light cross-offshore, which is a treat. The energy jumps to 289 (moderate energy). It’s clean, but it’s just a small wave and the spot is inconsistent, so it’s a gamble. The Thursday afternoon turns into a bit of a mess with onshore wind and questionable conditions.
Friday the 21st morning has a pulse of 5ft from the south, but the wind is cross-on and the conditions are marginal. The afternoon, however, is a standout for this first week. The wind goes glassy, absolutely dead calm, and the swell is 4ft from the south. It’s goin’ to be clean, but with the combined energy at 381 (moderate energy), it’s not a powerhouse. For a glassy session at an inconsistent reef, that’s the best on offer early on.
The weekend, from the 22nd to the 23rd, is a write-off again. Strong winds, choppy conditions, and poor surf. The 24th Monday morning has a glassy window with 3ft from the SSW, but again, it’s small and inconsistent.
Now, from the 25th of August, the real story starts to build. A long-period groundswell from the SE begins to arrive, with periods of 14 to 15 seconds. The size climbs from 4ft to 6ft by the 26th, and the energy is gettin’ serious, hittin’ 446 on the 25th and rocketing to 1524 (strong energy) on the 26th morning. The wind is light cross-shore, so it’s not perfect, but it’s manageable.
The true standout, the one you’ve been waitin’ for, is Thursday the 27th of August. The morning shows a solid 10ft swell from the SE with a 17-second period, and the wind is light cross-offshore from the NNE. The conditions are clean and the energy is massive at 4407 (very strong energy). This is a big, powerful groundswell, and for a reef like Hakashita, that long period will really wrap in and produce some excellent, powerful waves. This is for experienced surfers only – 10ft is too big for beginners.
The following Friday the 28th morning is even bigger, with 12ft from the ESE and glassy conditions. The energy is off the charts at 5781 (very strong energy). This is expert territory.
Saturday the 29th of August morning is the absolute peak of the swell. We’re lookin’ at a massive 15ft from the ESE, glassy wind from the NNW, and an incredible energy of 11232 (very strong energy). This is a once-in-a-while sort of event. It’s a monster, and only for the most experienced, heaviest of surfers.
The swell stays huge through the end of August and into the first of September, with 16ft to 20ft waves, but the wind becomes more cross-on, makin’ it less clean. The period stays long, between 13 and 14 seconds, so there’s plenty of power. The morning of the 1st of September has a 7ft swell from the south with a 14-second period and glassy conditions, which is a nice, slightly smaller option for experienced surfers after the big stuff.
So, to sum it up: the first week is mostly a bust, with a brief glassy window on Friday the 21st afternoon bein’ the only real highlight. The second week, however, is a proper swell event. The standout is the morning of Thursday the 27th of August – 10ft, long period, clean cross-offshore wind, and incredible energy. After that, the 28th and 29th mornings are massive, but only for the experts. The 1st of September morning is a good, cleaner option if the big stuff is too much.

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.
