The Lowdown
Alright folks, Rusty here. Let’s break down what’s coming at Takegashima over the next couple of weeks.
Right now we’re in a flat spell, so don’t bother paddling out until the 24th. The first real swell arrives Monday the 24th, and that’s where we should all be focusing. The water temp is around 83°F, which is pretty standard for this time of year, nothing unusual.
The standout window is Monday the 24th. In the morning, we’re looking at a 4ft swell from the SE with a period of 16 seconds. That’s a very long period groundswell, full of energy – combined energy is 804. But the big news is the glassy conditions, which is a massive plus. This is top-tier quality for Takegashima, clean and inviting. For the experienced crew, Monday afternoon gets even better: the swell bumps up to 6ft from the SE, still with that super long 16-second period and combined energy hitting 1911. There’s a risk of a thunderstorm, but the wind is light and cross-off, keeping it clean. This is the best on offer in the whole period.
Tuesday the 25th brings a big size jump to 12ft, but it’s not as clean. The wind is cross or cross-on, and the period drops to 15 seconds. The combined energy is massive at over 5400, so there’s plenty of power. This is strictly for experts at that size, and the conditions are more marginal. Wednesday the 26th stays big, around 8ft to 12ft, but the wind stays a problem with cross-onshore and cross conditions.
We get a bit of a reprieve on Friday the 28th. The swell is still a solid 8ft from the S with a 10-second period, and finally we get offshore winds. It’s still a big, powerful wave – combined energy is 1171 – and it’s clean. Good for experienced surfers again. Saturday the 29th morning offers a 5ft SSE swell with glassy conditions, which is a nice, clean smaller option to wrap up the first week.
After that, the first week of September sees a drop in quality. There’s a few glimmers – Tuesday the 1st of September morning has a 3ft SSE swell and glass, and the afternoon brings a nice-looking 5ft S swell with 14-second period and glassy conditions again (combined energy 930). That afternoon could be a real score if it lines up.
The second week looks pretty average overall. Winds get messy, and swells are either too big with bad wind or too small. The period from the 3rd of September onwards is a write-off for clean quality surfing, with onshore winds and choppy conditions ruling the roost. A couple of days have big swell (10ft on the 4th and 5th), but the wind is all wrong. It’s a stretch of waiting and watching.
So to put it straight: clear your calendar for Monday the 24th. That’s the real standout – clean, powerful, and beautiful. Friday the 28th is your backup for some clean bigger waves among the chaos. The rest is mostly a battle with the wind or waiting for the next good window.
Stay safe out there.

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.
