The Lowdown
Alright folks, Rusty here. Let’s break down what’s going on at Takegashima for the next couple of weeks.
The first few days are weak and messy. Monday the 14th is a bust with knee-high, short-period SE junk—barely 1.0m and 8 seconds. The morning’s glassy, which is nice, but the energy is only (148), so it’s more of a paddle than a surf.
Tuesday the 15th is where we see a flicker of hope. Morning glass, dead calm wind, and the swell bumps up to 1.3m from the SE at 9 seconds. Energy jumps to (284) and conditions are labelled glassy. This is the best session in the first week. Takegashima is a consistent advanced reef, and that offshore direction from the SW is what this spot likes—the swell is coming in from SE, which isn’t its absolute optimum, but with zero wind, it’ll be clean and fun for anyone who knows the lineup. Crowds are possible, so get in early.
Wednesday the 16th through Thursday the 17th is a dead zone. Onshore winds and crap waves below 1.0m. Don’t bother.
Friday the 18th gets interesting but not for everyone. Swell jumps to 2.4m from the E, still short period at 8 seconds, but energy ramps up to (1138). Morning onshore wind though, so it’ll be lumpy. This is borderline for beginners—2.4m is getting chunky.
Saturday the 19th sees a serious groundswell pulse: 3.5m from the ESE with a period of 15 seconds. That’s a very long period swell, full of energy (4717). But—and it’s a big but—the wind is onshore, NE at 10-20 km/h, so it’s going to be a bumpy, powerful beast. This is expert-only territory. Swell over 2.5m is for the brave, and that long period will make the reef sectiony and fast. The combined energy is massive (4717–5227). The direction is SE, which is fine for Takegashima, but the onshore wind is a killer for clean faces.
Sunday the 20th stays similar: 3.5m, SE groundswell at 14 seconds, but still onshore NE winds. Energy is (5518). It’s a raw, heavy setup that could be more fun for a kite surfer than a paddle surfer.
Monday the 21st and Tuesday the 22nd are a write-off. Swell hits 5.0m with winds up to 75 km/h, and the energy is (10359) to (14279). That’s a storm. Stay dry.
After that, the swell drops quickly. Wednesday the 23rd through Saturday the 28th features a mix of small, short-period dribble and some onshore chop. Nothing to write home about.
The standout is Tuesday morning, September 15th. 1.3m SE swell at 9 seconds, glassy conditions, light energy (284), and clean surf. Not huge, but quality. Takegashima is a consistent advanced reef, so if you’re experienced, this is the one to circle. Crowds are possible, so go early.
If you’re a pro and want a battle with the ocean, Saturday the 19th has the size and energy, but the onshore wind will wreck the face. Keep that in mind.
Water temp is about average for this time of year—nothing unusual.
Stay safe out there.
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.
