The Lowdown
Alright, this is Rusty, and I'm lookin' at what we've got for Takegashima. It's a reef setup that needs the right direction and a bit of patience.
Right now, the water is sitting at a warm 84°F, which is about 2°F above average, so it's a touch warmer than usual for this time of year. That's always nice.
The next week and a half is a real slow burn. You've got a long stretch of days where the waves are just too small or the conditions aren't quite right. There's a bit of energy showing up on Wednesday the 14th with a 2ft south swell, and that glassy morning session is your best bet for a clean but small wave.
The highlight really only starts to build around Sunday the 16th. Afternoon sees a shift, with the combined energy kicking up to 218 and the wind going cross-offshore. That's a solid sign. A 2ft easterly swell with a bit more push.
But the real standout? That's looking like Thursday, August 27th. Late in the afternoon, the swell jumps to 5ft from the southeast, and the energy rockets up to 543 – that's a serious step up in power. The wind swings straight offshore from the SSW at 12 mph, which is going to groom that reef perfectly. This one's for the advanced crew, though. At that size and with that kind of energy, it's going to be a peaky, powerful wave that's not messing around. It's far out, so keep your fingers crossed, but the signs are all pointing to a ripper.
For the middle of the second week, there's a period around Wednesday the 26th with a 3ft south-east swell and clean conditions, but nothing that matches the energy of that final Thursday.
For the first part of this forecast, honestly, it's more interesting for a kite surfer than a paddle surfer given the light winds and small swell.
So in short: lots of flat or marginal days, but hold out for that Thursday the 27th. That's the one to circle on your calendar.
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.
