The Lowdown
G’day, Rusty here. Let’s break down what’s on offer for Takegashima.
The first week and a bit is pretty flat and messy. Water temp is about 84°F, which is normal for this time of year.
Starting Tuesday August 11th, we’ve got 2ft easterly swell, 11-second period, with a northeasterly breeze – poor conditions. That theme sticks through the week: swell stays under 2ft, and winds are often cross or cross-onshore. Thursday the 13th afternoon has clean cross-offshore wind, but the swell is only 1ft – barely a ripple.
Friday the 14th afternoon shows a slight improvement: 2ft southerly, 9 seconds, clean with light cross-offshore breeze – surfable but nothing exciting.
The real action is at the tail end. Tuesday August 25th morning: glassy, 6ft southeast swell with a very long 13-second period, combined energy at 1027 (strong). That’s excellent for experts only. Afternoon hits 7ft, still long-period and clean. Wednesday the 26th morning: 10ft from the south-southeast, 14-second period, offshore southwesterly, energy at 3044 (very strong). This is big, powerful, and clean – strictly for experienced surfers. The afternoon stays similar in size with clean offshore wind but a gusty 16 mph breeze.
The 25th and 26th are the only windows worth chasing. Long-period groundswell will wrap well into the reef at Takegashima. Expect longer lulls but heavy sets. Crowds are possible. The rest of the 16 days? Mostly small and ordinary.
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.
