The Lowdown
Alright, let's talk in feet and knots. It's been a slow one, and it's gonna stay that way for a while.
For the first week or so, we're looking at a big fat zero. From the 10th through the 22nd of August, the surf is pretty much done. Save your wax. A whole lot of flat, weak, and messy days. The 10th had a tiny 3-4ft south swell, but that was a washout.
The 22nd and 23rd start to show a little life, with some waist-high waves, but nothing to get excited about.
The moment you've been waiting for is Monday the 24th of August at Takegashima. That's the one. The morning kicks off with clean 2-3ft waves from the south-east, glassy smooth, and the energy is building (moderate at 348). But the afternoon is the real deal. The swell jumps to 6ft with a long 13-second period, and the energy is pumping at 1137 (strong). This is a proper groundswell for a reef. The waves will have real shape and power. This is for advanced surfers only. The wind is a light cross-shore, so it's not perfect, but it's the best we've got.
Tuesday the 25th still has some serious energy in the water, with 6ft of south-east swell and a 12-second period, energy at 953 (strong), but the wind looks a bit more onshore, so it'll be a bit messier. A solid leftover from the day before.
So, here's the plan: wait it out for two weeks, then hit Takegashima on the 24th. That's the call.

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.
