The Lowdown
G’day, I’m Rusty, and here’s the outlook for Takegashima.
The next 16 days start off real quiet. Thursday the 20th has bugger-all on offer – tiny waves, weak energy (48). Glassy conditions on Thursday morning with a slight SSE wind, but the swell is only 1 ft, so it’s just a paddle. Things stay small and ordinary through Friday and Saturday, with a bit of a bump to 3 ft on Friday morning but still pretty average. There’s a gap of several days where nothing really stands out, then it all kicks off.
The real standout is Monday the 24th. That morning, the swell jumps to 6 ft from the SE with a long 17-second period, glassy conditions, and a light SE wind. The wave energy is pumping (2493). This is excellent for experienced surfers – the water temp is 83°, about normal for this time of year. Monday afternoon gets even better, with the swell building to 8 ft and the same long period, still clean with a cross-off breeze. That’s the pick of the whole forecast.
Tuesday the 25th is a monster. The morning sees 15 ft swell from the SE, but it’s onshore and the energy is huge (11721). That’s expert-only territory, and the wind is not ideal – it’s cross-on. By afternoon, it’s 16 ft and even more energy (15454), but the wind is cross-on, making it messy. Honestly, this is more for tow-in or kite surfing than paddle surfing.
After that, the week turns rough. Wednesday the 26th has 18 ft swell but with 16 mph cross-on winds and rain, so it’s blown out. Thursday the 27th is similar, with 13 ft and 19 mph cross-shore wind. Not good.
Friday the 28th brings a welcome drop in size – 7 ft in the morning, cross-off breeze, and clean. The swell is shorter period (10 seconds) but the energy is moderate (756). That’s a solid session for those who know the reef. Saturday the 29th is smaller at 4 ft and a bit choppy, but Sunday the 30th afternoon has 6 ft, cross-off wind, and clean lines – a good option.
The last few days of the forecast, into early September, fade back to small, weak surf, with onshore winds and poor conditions. Nothing to get excited about.
So, bottom line: Monday the 24th is the day to mark. Excellent surf for experienced surfers, clean and powerful. Tuesday the 25th is massive but messy. Friday the 28th and Sunday the 30th are your backup sessions.
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.
