The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Takegashima.
The next 16 days start off a bit flat and pretty quiet, but once we get into the second week, things start to look a whole lot more interesting. For now, we’ve got a fair stretch of small, ordinary days to sit through before the real juice arrives.
Tuesday and Wednesday are tiny with barely any energy. A 2ft easterly swell on Tuesday morning with a bit of ENE wind is not worth getting wet for. Wednesday morning offers a slight improvement – glassy conditions and a 2ft southerly swell, but it’s pretty underwhelming. The combined energy is just weak (104), so honestly, you’re better off waiting.
Thursday is a write-off. We’re down to 1ft and storm risk hangs around. The energy is pitiful (33). Friday and Saturday are more of the same: small south swells at 2ft with glassy mornings but again, combined energy is weak (131-126). The water temp is sitting at 84°, which is about normal for this time of year, no surprises there.
Now, Sunday August 16th is the first day that catches the eye. The morning has a 2ft S swell at a 10-second period with glassy conditions, and the combined energy jumps to a moderate 206. The forecast note says “expect good surf conditions” – that’s the first real green light. It’s still small, but clean and with enough push to make it fun. It should be a standout for a quiet window.
From August 18th through the 20th, it goes flat again. Energy levels drop back under 100, and you’ll be scratching for anything rideable. A gap of about three days where there’s basically nothing doing.
Friday August 21st afternoon is where things start to ramp up. The swell bumps to 4ft from the south with an 11-second period, and the combined energy is a solid 305. Light, clean winds and that south direction is exactly what Takegashima needs. This is another proper standout for the forecast period.
Then Tuesday August 25th is when it gets serious. Morning brings a 3ft S swell but with a very long 14-second period – proper groundswell. The combined energy shoots up to 382. That’s a big jump. By the afternoon it’s 5ft with a 13-second period and energy at 836. But this is an advanced reef break, and 5ft at this spot could be a handful. Winds turn to a moderate breeze, so it’s clean but a bit raw. That afternoon is one for experienced surfers only.
Wednesday August 26th keeps the trend going. Morning swell hits 6ft from the south, 13-second period, combined energy at 1141 – now we’re into strong wave energy territory. Afternoon sees 6ft and 14 seconds, with energy up at 1378. This is big, powerful, long-period swell. Remember, with periods that long at a reef break, it’ll be lined-up and fast, but the sets will be widely spaced. It’s all expert-only territory at this point, and it’s still 9 days out so treat it as promising but not set in stone.
The crowd factor at Takegashima is “sometimes”, so on these standout days, you might have company but it won’t be a circus, especially if you pick the morning windows.
So, to wrap it up: the first week is a slow burn. Sunday August 16th morning and Friday August 21st afternoon are your best bets for clean, surfable waves without the heavy juice. For the big stuff, August 25th into August 26th is where the swell lights up, but that’s only for the crew who know what they’re doing on a reef.
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.
