The Lowdown
Alright, let's talk about Takegashima. This is a reef setup, so only for the advanced crew.
The start is slow. Sunday the 23rd has tiny 1ft waves from the ESE, a long 11-second period, but the energy is weak (41). Water temp is a warm 82°, pretty normal for this time of year.
Monday the 24th morning is where it kicks off. We've got a 4ft SE swell, a massive 19-second period – that's proper groundswell – and glassy conditions. The combined energy hits 1275 (moderate). This is a standout, but being a reef, that long period will make for some lined-up, powerful waves. Experts only.
Tuesday the 25th is the big one. The morning brings a solid 12ft SSE swell, period of 15 seconds, and cross-off winds. The energy is a strong 4671. This is the best of the lot. The afternoon holds 10ft too. This is strictly for experts – the size is serious.
Wednesday the 26th morning is still chunky with an 8ft S swell and glassy conditions, energy at 2766. It drops off in the afternoon. There's a lull until Friday the 28th morning, which offers a clean 5ft S swell with glassy conditions and energy of 518. Good window.
From the 1st of September, the swell is there, but the wind turns onshore and messy. The 5th of September afternoon looks like a good comeback with a 8ft S swell and clean offshore winds. It's promising but less certain this far out.
The standout is Tuesday the 25th – big, powerful, and clean. Monday the 24th is a close second for that long-period groundswell.

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.
