The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Hakashita over the next couple of weeks. It’s a bit of a mixed bag, so I’ll walk you through it day by day.
First up, a quick note on the water: it’s sitting at a warm 84°, which is pretty much spot on for this time of year, so don’t expect any surprises when you jump in.
The real action for surfers is tucked away towards the back end of the forecast, but we gotta get through some ordinary days first. The opening Sunday (30th August) has a small, weak 3-foot SSE swell with a combined energy of just 156. It’s surfable but nothing to write home about. The period is short at 7 seconds, so the waves will be a bit fat and weak. Monday (31st August) sees the swell drop right off to 1 feet, with a long 11-second period from the east. That’s a groundswell, but there’s just no size, and energy is down at 114. Not worth paddling for.
We get a lifeline on Tuesday (1st September) with a bump in size to 4 feet and 4 feet from the SSE, and the energy creeps up to 283 in the afternoon. But the wind is cross-onshore, both the morning and the afternoon are only marginal, and there’s a risk of thunderstorms. It’s not great. Wednesday (2nd) and Thursday (3rd) are similar: a bit more size (5 to 6 feet), but the cross-onshore breeze and risk of storms keep things messy. The energy climbs, hitting 663 on Thursday afternoon, which is moderate, but the wind just won’t let it shape up clean.
Now, here’s the first real glimmer of hope. Saturday morning, 5th September. The wind turns glassy, straight offshore from the south, and the swell is a solid 5 feet from the S with 334 combined energy. That’s a clean, offshore window. The waves might be a bit short period at 7 seconds, so it’s not a deep groundswell, but that glassy face is going to be fun for an intermediate surfer. The crowd factor is listed as “sometimes”, so you might have a few others out, but it won’t be a zoo. This is your best bet in the first week – a proper little Saturday morning session.
Then we hit a quiet patch. Saturday afternoon (5th) turns onshore and choppy, and Sunday morning (6th) brings a tiny 4-foot SSE swell with a super long 13-second period. The energy jumps to 1051, which is strong, but the wind is cross-shore. That long period from the SSE at a reef break like Hakashita should actually line up pretty well. It’s a groundswell, and the direction is good, but the size is small and the wind is only okay. It might surprise, but it’s a gamble.
After that, we get a lull in quality for several days. From Monday 7th right through to Saturday the 12th of September, the swell is pumping – we’re talking 8 to 13 feet from the SE and SSE. The combined energy goes through the roof, peaking at a massive 6028 on Tuesday the 8th morning. That’s very strong wave energy. But here’s the catch: the winds are mostly cross or cross-onshore, and there’s a big risk of thunderstorms every single day. The surf will be big, powerful, and period is long (12-14 seconds), but it’s going to be lumpy, choppy, and a real battle. This is only for expert surfers – the swell is well over 8 feet for days on end. For the average punter, it’s a look-and-stay-out day.
The standout in the entire 16-day window, and the one I’d circle on the calendar, is Monday, 7th September morning. The swell is 8 feet from the SE, period 14 seconds (so a solid groundswell), and the combined energy is 3232. The wind is a light cross-onshore from the east at about 6 mph. That’s not perfect, but it’s workable, and the reef will handle that direction well. The size is at the upper end for strong intermediates, but experts will be in heaven. The crowd factor is “sometimes”, so you won’t be alone, but on a big Monday like that, you won’t be fighting for every wave. Just watch out for those thunderstorms.
From the 13th of September onward, the whole thing falls apart. Strong southeasterly winds (22-25 mph), rain, and dropping swell. By the 14th, the energy is back down to 376, and conditions are just poor. Not worth it.
So to wrap it up: if you want clean, smaller waves, hit Saturday morning, 5th September. If you’re an expert looking for the biggest, most powerful standouts, Monday morning, 7th September is your best shot, but be ready for a lumpy, thunderstorm-ridden session.
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.
