The Lowdown
G’day, Rusty here. Look, straight up, the next few days are pretty flat and ordinary for Takegashima. There’s a bit of tiny, weak swell around but nothing worth paddling out for until later in the week.
We’ve got a real gap here. From Tuesday morning the 18th right through to Thursday the 20th, the waves are tiny—under 3 feet—with short periods and not enough energy (combined energy values of just 66 to 84). Winds are light cross or cross-offshore, but it’s just not doing anything. You’d be wasting your time.
Friday the 21st is where things start to get interesting. The morning is glassy (ESE 3 mph) with a 3-foot swell from the south at 9 seconds, and energy jumps to 178 (moderate). It’s surfable but still ordinary. The real spark comes Friday afternoon: a 3-foot south swell at 10 seconds, combined energy of 234, with clean cross-offshore winds (SSE 6 mph). That’s your first proper session of the week—small but clean.
Saturday the 22nd and Sunday the 23rd drop right back off. Tiny waves under 2 feet, even with glassy mornings, the energy is pathetic (25 to 61). Not worth suiting up.
Now, Monday the 24th is where we start to see something special building. The morning is glassy (SE 3 mph) with a 3-foot south-east swell at a very long 16 seconds—that’s proper groundswell energy. The combined energy is 697 (moderate-to-strong). It’s clean and building. Then Monday afternoon it kicks: 5 feet from the SE, same 16-second period, and the energy rockets to 1343 (strong). Clean cross-offshore winds (SSE 6 mph). This is the first standout—good for experienced surfers, clean, and that long period will wrap nicely into this reef setup.
Tuesday the 25th is the big one. Morning session: glassy (NE 3 mph), 8-foot SE swell at 16 seconds, and the combined energy is 3737 (very strong). This is excellent for experienced surfers—big, clean, long-period groundswell. The afternoon gets bigger (10 feet) but the wind goes cross-shore (ESE 6 mph), and the forecast flags questionable tide conditions. Still, the morning is your standout session of the whole outlook.
Wednesday the 26th sees the swell getting huge—10 to 13 feet from the SSE at 16-17 seconds. Energy is massive (5315 to 8004). But the wind turns onshore and cross-onshore (NE to ENE 9 mph), making it choppy and marginal. This is expert-only territory, and honestly, it looks more interesting for kite surfing than paddle surfing with that wind and size.
Thursday the 27th is a write-off. 13 to 15-foot SSE swell but howling cross-onshore winds (NNE 12-16 mph) and choppy. Poor conditions.
Friday the 28th, the wind swings around to a glassy NW 3 mph in the morning, then NE 3 mph in the afternoon. The swell drops a touch to 13 then 12 feet from the SSE at 14 seconds, but the energy is still massive (5854 to 5434). This is exceptional for experts—clean, glassy, huge groundswell. If you’ve got the skill, this is another standout.
From Saturday the 29th into September, the swell slowly backs off from 10 feet down to 5 feet, but the winds turn more cross-shore to onshore, and conditions become marginal. The energy remains strong early on (over 4000) but drops to moderate by Wednesday the 2nd (703 to 486). Nothing clean or exceptional after the 28th.
For the standout, I’m calling Tuesday morning the 25th as the best on offer—glassy, 8-foot SE groundswell at 16 seconds, very strong energy, and clean. Monday afternoon the 24th and Friday the 28th are also top-tier sessions. Keep in mind, Takegashima is a consistent reef break exposed to swell, and crowds are sometimes an issue, so get in early.
Water temp is 83°, which is about normal for this time of year (anomaly 1°).

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.
