The Lowdown
Alright, this is Rusty, and I’m looking at what’s cooking for us here in the Takegashima zone. It’s a reef, and it’s an advanced-level setup, so if you’re not confident in the water, maybe sit this one out. The water’s sitting at a warm 84°, which is a touch warmer than normal for this time of year, so you can leave the thick rubber at home.
We’ve got a decent run of clean conditions kicking off this Tuesday afternoon (25th August). The swell is a solid 8 ft from the SSE, with a period of 13 seconds. That’s a proper groundswell, and the combined energy is strong at 3331. The wind is a light S at 6 mph, so it’s cross-off, keeping things nice and clean. This is the standout for the whole outlook – excellent surf for experienced surfers, but it’s a lot of water moving, so only for the crew who know what they’re doing.
Wednesday morning (26th) still has some punch, with 7 ft from the S and a moderate 11-second period. The energy is still strong at 1145, and light SSW winds keep it clean. The afternoon drops off to 5 ft, still clean, but the energy is fading and the wind picks up to 12 mph, so it’s less exciting.
Moving into Thursday (27th), the swell drops right down to 4 ft in the morning, with a short 9-second period, and the energy is weak at 227. The wind goes offshore though, so it’s glassy and clean. Thursday afternoon is similar, with a gentle offshore breeze, but the swell is still small. After that, we hit a dry spell. Friday (28th) morning is tiny – 3 ft with a short 8-second period, and the energy is barely there at 95. It’s glassy, but very ordinary. From Friday afternoon right through to the end of August, it’s all poor surf. Saturday and Sunday (29th-30th) are especially grim, with waves barely breaking 1 ft. The energy is in the teens and low 40s. There’s a gap of about five days of just poor to ordinary conditions.
Then on Monday (31st) morning, we get a tiny ripple of 2 ft, and the afternoon picks up a little to 3 ft from the SSE with some energy at 207, but it’s still pretty small. Then we get a bump in size from the 1st of September, but the wind turns against us. Tuesday (1st September) has 5 ft to 5 ft with strong energy 1064-1217, but it’s a cross-onshore wind at 12 mph, so it’s going to be choppy and messy. This pattern of bigger but messy swell continues right through the next week. The energy is strong, often over 1000, with waves from 6 ft to 8 ft, but the wind is almost always cross-onshore, keeping it rough and marginal. The best of this later period is on the 9th of September (Wednesday morning) – a clean, glassy 10 ft from the E, but again, that’s 10 ft of swell on a reef, so it’s for experts only. The afternoon is still big at 8 ft, but the wind goes cross-shore, so it’s not as clean.
So, the real standout is this Tuesday afternoon (25th August) – it’s the best balance of size, period, and clean wind. The rest of the first week is small or poor, and the second week is bigger but messy. If you’re a confident surfer and you’re free this Tuesday, that’s your window.
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.
