The Lowdown
Alright, Rusty here with a look at what we've got cookin' over the next few weeks.
First up, Friday the 21st is just a tease. Takegashima is showing some tiny little 3ft swell from the south, period around 9 seconds, and the morning is glassy. It's surfable, but honestly, it's very ordinary. The water's sitting at a warm 83°, which is pretty average for the time of year.
Then we hit a real flat patch. Saturday the 22nd right through to Sunday the 23rd is essentially a write-off – tiny wobbly stuff under 2ft, no energy to speak of. Don't bother paddling out.
Things start to get interesting Monday the 24th. The morning bumps up to 5ft from the southeast, but it's a bit messy with some cross-shore breeze. The real story is Monday afternoon: the swell jumps to 8ft from the southeast, period a solid 16 seconds, and the wind goes cross-offshore making it clean. This is for experienced surfers only – that's a powerful wave with moderate to strong energy. This is one of the standout sessions.
Tuesday the 25th sees the swell peak. We're looking at 13 to 15ft from the south-southeast, with a long 16-second period. The energy is huge. But, and it's a big but, the wind is cross-onshore both morning and afternoon. The wave size is massive, but the quality is marginal because of the wind. This is for the hardcore crew only.
Wednesday the 26th and Thursday the 27th remain big, with swell holding around 12ft, but cross-onshore and cross winds keep things choppy and messy. Not your classic day, but there's raw power there for the brave.
We get a bit of a reprieve Friday the 28th. The swell drops to a more manageable 7 to 8ft from the south-southeast, period around 9 seconds. The morning is completely glassy, and the afternoon is cross-offshore. The wave energy is still moderate. This is another strong contender for the best of the run – clean and powerful for those who know what they're doing.
After that, it fades out. From Saturday the 29th all the way through to Saturday the 5th of September, we're looking at small, weak, and mostly onshore or cross-onshore conditions. There's a flicker on Thursday the 3rd of September with an 8 to 12ft long-period groundswell from the east (period 19-20 seconds, energy shooting up), but the wind is cross-onshore/cross, and that long-period stuff breaks straight at a reef. That's a more promising but uncertain prospect this far out.
So to wrap it up: for the cleanest, most powerful, and most manageable swell, hammer it on Monday the 24th afternoon or Friday the 28th morning. Those are your standout windows.

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.
