The Lowdown
Alright, surfers, Rusty here. Let’s get straight into it for Takegashima. The next couple of weeks are a real mixed bag, and honestly, the first week is pretty grim. We’re looking at a whole lot of small, weak surf and cross-shore winds that'll have things looking a bit of a mess. For a spot like this that needs a decent swell, the first stretch is a write-off for the most part.
The opening days, through the 20th, are mostly poor with just ankle to knee-high slop. The energy's all weak, and with winds sitting cross or cross-onshore, you aren't missing much. The best you'll get is a couple of afternoons where the wind swings cross-off and cleans it up, but we're still talking about tiny, weak waves that aren't worth paddling out for.
We finally get a pulse of energy on the 21st, with the swell picking up to a modest 5ft. It’s still a marginal call with onshore winds, so keep your expectations low. That’s it for round one, though. The surf then drops right back off again into the 22nd and 23rd. More knee-high dribble and practically no energy, so keep the board in the car and don't bother.
Now, the good stuff. Mark your calendars for the 24th of August. This is where it starts to get seriously interesting. The swell builds to 6ft, then 7ft, and the energy just explodes into the very strong range. The period is a proper 16 seconds, and with a light cross-offshore breeze predicted, the waves are going to have some serious power and shape. This is a solid, clean groundswell that will have Takegashima looking like a different spot. It won’t be for beginners, but for the advanced crew, this is the standout window of the whole period. The light winds are a huge plus here.
The following day, the 25th, the swell holds at 8ft with the same long 16-second period, and the energy is massive. Tuesday afternoon looks the pick, with the wind dropping to glassy. This is heavy, powerful surf, the kind that will have your heart pumping. This is expert territory for sure. The period is very long, so the sets will be fat and organized, perfect for a clean reef like this.
From the 26th, it's still big, with 8ft to 10ft surf and a 15-second period. But the winds start turning onshore and the quality drops off. The 27th sees the swell push to 12ft, but with a proper onshore breeze, it’s going to be a washing machine. We’re in the realm where it’s just too big and messy to be any fun unless you’re a total charger. Then the 28th comes with 13-15ft of swell and a strong 30 km/h cross-onshore wind. That’s a full-blown, lumpy, blown-out mess.
The 29th is a monster. We're talking 25ft of swell. That's just colossal, way too big for this break and actually dangerous. The good news is the wind is cross-offshore, so it will be clean, but for kite surfers, this will be a dream. For the paddle surfer, it’s a hard pass.
We then see it start to fade out. The 30th and 31st have big leftover swell, but the periods drop off and the winds are onshore and messy. It’s a poor finish to what could have been an epic run. So to sum it up: the first week is for doing something else. The 24th and 25th are your days. Get on it.
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.
