The Lowdown
Alright, Rusty here. We’ve only got one spot to talk about for this stretch, so let’s get into it. The forecast window starts on Wednesday, August 12th, with small surf and just ordinary conditions.
First up, Takegashima (a reef setup for advanced surfers, exposed to the swell). From Wednesday morning, we're looking at 2.3ft of southerly swell, with a 10-second period. The combined energy is moderate at 107. The wind is glassy, which is a major positive, keeping things clean. But honestly, the waves are surfable but very ordinary – nothing to get excited about. This pattern of small, mediocre surf continues through Thursday and Friday, with the swell dropping to 1.0ft and even 0.7ft on Thursday. The water temp is about average for this time of year, nothing unusual.
The weekend rolls in, and we see a slight bump. Saturday morning has 2.3ft of S swell, with a 10-second period, and glassy winds again. Energy climbs to a moderate 148, but the wave comment still says "surfable but ordinary." Saturday afternoon turns cross-shore and messy. Sunday gets a bit more size – 3.3ft from the ESE but with a short, weak period of 6 seconds. That is not a good sign; the wave energy is moderate at 191, but the wind is cross-on and the conditions are poor.
The first half of next week stays small and underwhelming. Monday morning has 2.3ft of ESE swell, a 10-second period, and clean cross-off winds, but it’s still just "surfable." Tuesday and Wednesday of that week are even smaller, with readings around 1.3-2.0ft. The energy drops right off (down to 45-80), and the surf is either poor or very ordinary. The break is consistent, but with these tiny waves, that doesn't mean much.
Then we hit the second week. There’s a real gap here – from Monday, August 18th, through to Tuesday, August 25th, the surf is persistently weak and mostly un-rideable. It’s a long, flat period with nothing to recommend.
But hold on. On Wednesday, August 26th, things get interesting. Takegashima fires up. We’ve got a 3.9ft groundswell from the SSE, with a long 11-second period. The combined energy is strong at 318, the winds are glassy, and it says "expect good surf conditions." This is the standout of the entire outlook. For a break that needs E swell to be at its best, this SSE direction isn’t perfect, but the quality of the incoming swell and those clean conditions make it the clear pick. It’s a reef, so that long-period energy will wrap in nicely. This is an advanced wave, and at 3.9ft, it pushes the limit for an intermediate. The crowd factor here is "sometimes," so you might not have it totally to yourself.
After that, Thursday morning gets blown out with a cross-on wind and 5.6ft of swell. That’s getting head-high plus, but the conditions are poor – more for experts only if they’re keen, but honestly, it looks messy.
So, bottom line: the first two weeks are a bust for anything decent. The only real highlight is the morning of Wednesday, August 26th. Mark it on your calendar. That’s the one to chase.

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.
