The Lowdown
Alright folks, Rusty here. Let's get straight into it.
The next couple of weeks are a bit of a mixed bag. We’ve got a solid start to the forecast, but there’s a real flat spell in the middle that will test your patience. The real magic is bookended at the start and way out at the end, but you'll have to be willing to wait for that last one. And when it’s on, it’s *on*, but this isn’t a spot for the faint of heart.
Tuesday (25th) is where we kick things off, and Takegashima (Japan) is the only game in town. The water temp is about average for this time of year, so a springsuit is still the go-to. We’re looking at a clean 9.8ft of SSE groundswell with a 14-second period. The energy is strong, reading at 4834 in the combined energy. That’s a lot of water moving. The wind is a slight cross-off at 3 mph, so it should be glassy and lined up. This is serious, powerful surf for experts only – over 8.2ft means it’s not for messing around. The morning is the pick, with the afternoon dropping slightly to 8.2ft but still holding that excellent quality.
Wednesday (26th) keeps the fun alive. The swell eases to a still-chunky 6.6ft from the S with a 13-second period. The energy is moderate at 1501. Winds stay light and offshore, so it’ll be clean and rippable. Quality remains excellent for those who can handle it. The afternoon sees the size drop to 5.6ft and the period to 12 seconds, making it a bit more manageable. The energy backs off to 1059, but it’s still a worthwhile session, though the tide might be a factor.
Then we hit the lull. From Thursday (27th) through Monday (31st), the swell just falls out of bed. We're talking ankle to knee-high slop. The energy readings are in the low hundreds or even double digits – weak stuff. The wind might be glassy or offshore at times, which will be teasing, but there’s just no power. There’s a small bump Thursday afternoon with a 3.6ft S swell and a moderate offshore wind, but it’s still not worth getting wet for. This is a stretch of several days where you’re better off tuning the board or working on your pop-up on land.
Tuesday (1st September) brings a change, but not a good one. The swell builds back up to 5.6ft from the S, but the wind swings onshore from the ESE. This brings lumpy, choppy conditions, and the quality drops to marginal. The energy is back up to 748, but it’s messy. This is more of a battle than a pleasure.
Wednesday (2nd) and Thursday (3rd) see the size jump up significantly, with 8.2ft and then 9.8ft S swells. But the wind is howling from the S and SSE at 16-22 mph. While it’s cross-off, which keeps it clean-ish, the power is there but the conditions are challenging. The energy is strong at 1843 and 1545, but for a spot like this, with that much wind, it starts to look like a kite-surfing session more than a paddle-surfing one. Still, it's big and clean, for the experts who want a challenge.
Friday (4th) is a bit more promising. We’re down to 5.6ft S swell, but the wind is a lighter cross-off, making for cleaner conditions. The energy has dropped back to 393, but it should be more organized. It’s not huge, but the quality should be there.
Saturday (5th) is a little better again. Swell builds slightly to 5.6-6.2ft from the SSE/SE, with light winds keeping it clean. The energy is moderate at 423-486. It's a workable day, with good conditions for the size, but still not the standout.
Sunday (6th) is the big one, the main event if you can wait. The swell jumps to 11.5ft in the morning and 13.1ft in the afternoon, from the SSE with a long 14-second period. The energy is massive – over 5000. This is a huge, powerful swell. The morning has a slight cross-on wind that could add some texture, but the afternoon sees a moderate cross-off breeze, which should hold it open. This is a code red, experts-only day. The period is long, and at a reef break like this, it should be absolutely firing. This is the standout of the entire forecast, but it is more than a week away, so treat it as promising but not locked in.
Monday (7th) is still solid as the swell eases to 9.8ft and then 8.2ft. The wind is light and cross-off in the afternoon, creating what the data calls “excellent surf conditions for experienced surfers.” The energy is still strong at 1948 and 1838.

Information about the Takegashima Surf forecast
The above surf forecast table for Takegashima provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Takegashima can be found by selecting the local surf guide option on the grey menu. Our Takegashima 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 (Takegashima) 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 Takegashima 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.
Takegashima is 33 km (20 miles) from Muroto. If you plan a holiday in Shikoku, look for hotels and other accommodation in Muroto. Muroto has rooms for a wide range of budgets as well as car hire and transport links.
