The Lowdown
Alright, Rusty here. Let's talk about what's cooking.
First up, the water's a touch warmer than usual for this time of year, so you can leave the thick rubber at home.
We've got a bit of a slow start, but things build nicely. The real standout action is looking at Takegashima (reef) from the morning of Thursday, August 20th, right through to the afternoon of Saturday, August 22nd. That's your window.
Thursday the 20th afternoon sees a clean 4ft swell from the SSE, and the wind is offshore and gentle. It's clean and it's got a decent push with moderate wave energy (235). This is where you want to be.
Friday the 21st is the pick of the week. Morning swells are 5ft from the S, and by the afternoon they're 6ft. The wind stays offshore and gentle, so the faces will be clean. The wave energy climbs to strong (367 morning, 402 afternoon). This is proper size for the advanced crew, and the reef will handle that long-period groundswell just fine. Remember, this swell is a bit short on period (8 seconds), so it won't be as drawn-out as a proper groundswell, but the power is there.
Saturday the 22nd morning and afternoon hold onto some energy with 4ft and 4ft swells from the S, and it's glassy. Perfect morning session before the wind changes.
After that, the swell drops away quickly. We go from that solid punch on Saturday into a long, quiet stretch from Sunday the 23rd through to Wednesday the 27th of August. It's mostly tiny, weak waves with clean conditions but nothing worth paddling out for. There's a tiny pulse on Monday the 24th afternoon, but it's only 2ft and cross-off.
The earlier part of the period, from Wednesday the 12th up to Tuesday the 18th, is just flat or junky. Small swell and mostly onshore or cross winds. Not worth a second look.
So, to sum it up: the wait is on until Thursday the 20th. Friday the 21st is the day to circle on the calendar for a solid, clean session at Takegashima. It'll be good but expect the locals to have it wired. Get in the water.
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.
