The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
It’s a slow start, I won’t lie to ya. The first few days are a write-off, with nothing but tiny, weak little waves and poor conditions gumming things up. We’re looking at a gap of almost a week before anything really starts to get interesting. The better news is that the second half of the forecast period looks like it could be a real corker, especially for the crew who can handle some size.
Hakashita (a reef setup) is the only spot on the cards. The water's sitting at a pretty normal 83°F for this time of year, so no surprises there.
The first real glimmer of hope comes on Thursday, August 21 morning. The swell is still small, only about 4ft from the South, but it's got a bit more period behind it (10 seconds) and the wind is glassy. The wave energy is moderate (257). It’s not going to blow your mind, but it’s the first session that’s actually worth paddling out for.
Things take a big step up on Monday, August 24 morning. A clean 3ft swell from the SE with a long 14-second period, and glassy conditions. The energy is ramping up (485) and it’s a proper groundswell. That’s a nice, clean day for a longboard or a funboard.
Then, hold onto your board shorts. The real standout is shaping up for Thursday, August 27 morning. We’ve got a powerful 15ft swell from the SE with a very long 16-second period. The wind is glassy and cross-offshore, and the combined energy is massive (10266). This is an exceptional day for expert surfers only. That size and period on a reef break is a serious proposition, not for the faint of heart. The waves are going to be lined up, but the power is immense. The morning of Friday, August 28 is also a standout candidate with a 13ft SE swell, glassy conditions, and a 15-second period (6635 energy). Crystal clear, no wind, just pure, powerful ocean.
A couple of days later, on Monday, August 31 morning, is another one to circle: 12ft from the SSE with a 13-second period, glassy conditions, and a solid energy of 5829. Another excellent session for the experienced crew.
To be honest, the whole last week from the 24th onwards is pumping with solid, long-period groundswell, but the wind is a little tricky on the afternoons, tending to get a cross-onshore kick. The mornings are where it’s at, especially the 27th, 28th, and 31st.
Rusty out.

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.
