The Lowdown
Alright, Rusty here, let’s have a look at what’s cookin’ for Takegashima.
Right off the bat, the story for this 16-day run is *size*. We’re talkin’ solid groundswell, and I mean serious juice. The water’s sittin’ pretty close to the long-term average, so nothin’ freaky temperature-wise, just typical conditions for this time of year. The first proper swell to get excited about rolls in on Tuesday the 4th of August. That morning we’re lookin’ at a solid 10-foot of east-southeast groundswell, running a long 16 seconds. The combined energy is already pumpin’ at 5107 (moderate to strong), and the wind is just a light cross-shore. This is a big, clean wave, but at that size, it’s strictly for the advanced crew.
Wednesday the 5th is where it really kicks off. The swell jumps to 15-foot in the morning from the southeast, period still a dreamy 17 seconds. The energy reading climbs to 12450 (strong). Wind stays light cross-on from the east-northeast, which isn’t perfect but it’s workable. By the afternoon, it’s hitting 18-foot and the tide and wind are favourable, but honestly, at this size – that’s a monster. The combined energy is a whopping 16068 (very strong). This is expert territory only. If you’re not absolutely dialled in on this reef, stay on the rocks and watch.
Thursday the 6th is the peak of the swell with a massive 21-foot to 23-foot wave. The energy numbers are off the charts – 26830 and 29513. That’s some serious, heavy ocean. Onshore winds kick up, making it look a bit messy, and frankly, it’s too big for even most experienced surfers. The rest of that week and into the next is all messy, blown-out leftovers with cross-on winds and dropping swell quality. It’s a write-off from Friday the 7th right through until about Wednesday the 12th of August.
We do get a little reprieve around Thursday the 13th of August. Small glassy conditions roll in, but the swell is tiny – only 4-foot from the south with a 12-second period. It’s clean, but barely surfable. Then it drops right off again into the weekend.
There’s a bit of a late bloomer on Monday the 17th and Tuesday the 18th of August. We get some glassy mornings with a small 6-foot easterly swell, but the period is really short, only 6 to 7 seconds. Combined energy is low, around 300. The shape will be weak and crumbly.
So for the standout in this whole outlook, it’s gotta be Tuesday the 4th of August and Wednesday the 5th. The 4th gives you a 10-foot, 16-second east-southeast groundswell with light cross-shore winds– that’s gonna be a proper session for the chargers. Wednesday the 5th hits a massive 18-foot from the southeast with a 17-second period – pure, raw power, but only for the top-level local rippers. This reef break (Takegashima) is exposed, and with a consistent, long-period groundswell like that, it’s going to be heavy, walled-up, and demanding. Crowds are possible here, so pick your peak.
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.
