The Lowdown
Alright folks, Rusty here. Let’s take a long, hard look at what’s coming down the line for Takegashima. It’s a bit of a slow burner this one, but there’s a serious pulse of energy on the horizon if you’ve got the patience for it.
The first few days are pretty flat. We’re talking about a stretch from Wednesday the 19th right through to Sunday the 23rd of August where the surf is barely a whisper. The swell is tiny, mostly under 3 ft, and the energy is weak (48 to 196). The water is a warm 83° which is about average for this time of year, but the lack of any real push means you’re not missing much. You’ll be bobbing around on a lot of nothing.
Things finally start to tick over on Monday the 24th of August. The morning shows a clean 3 ft swell from the SE with a long period of 13 seconds, and the energy picks up to a moderate 293. The wind is a light cross-offshore, keeping things tidy. The afternoon is where it gets better: the swell bumps up to 4 ft from the SE, the period stretches out to a very long 15 seconds, and the energy jumps to 591. The conditions are clean and the waves will have some real shape to them. This is the first window of decent surf.
The standout period, however, kicks off on Monday the 31st of August. That morning, the swell is 7 ft from the SE, but it’s a bit onshore. The real magic happens in the afternoon. The wind goes glassy, dead calm, and the swell is a solid 8 ft from the SE with a period of 13 seconds and a strong energy reading of 3336. This is excellent surf for experienced surfers. The combination of that size, long period, and glassy conditions will make for some epic, clean lines at the reef.
The quality holds into Tuesday the 1st of September. The morning is a stunner: 12 ft of groundswell from the SE, a period of 13 seconds, and a massive energy of 3975. It’s glassy again. That’s big, powerful, and clean – expert territory only. The glassy conditions continue into Wednesday the 2nd of September morning with another 12 ft pulse from the SSE, period at 14 seconds, and energy of 4130. This is the absolute peak of the run. If you can handle the size, these few days are the best on offer.
After that, the swell starts to back off. By Thursday the 3rd of September, it’s down to 6 ft with a shorter period of 8 seconds, and the energy drops to 339. The winds are glassy again, but it’s a lower quality, more ordinary wave. The afternoon of the 3rd and Friday the 4th of September see it dropping further to 5 ft and 5 ft, still glassy, but the real juice is gone.
So to wrap it up: the first week is a write-off. The real action is tightly packed into the end of August and the very start of September. The absolute best window for experienced surfers is the afternoon of August 31st through to the morning of September 2nd, with that big, clean, glassy groundswell. The morning of September 1st and the morning of September 2nd are the true standouts. Just be aware, with that kind of quality and size, the crowds at Takegashima are likely to be a factor.
Rusty.

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.
