The Lowdown
Alright, let’s break it down.
Takegashima is looking at a bit of a rough start. We have some serious size coming in, but the wind is going to mess up the surface for a few days. The water temp is at 85°F, which is a touch warmer than average for the season, so it’s nice out there.
Thursday morning (August 6) starts off with a 15ft swell from the southeast, with a 14-second period – a solid groundswell. Wave energy is strong at 8335, but the NE wind is blowing 12 mph and onshore. The report calls it poor surf. Later that same Thursday, the swell jumps to 18ft out of the SE with a very long 15-second period. That’s a massive amount of energy (21621) moving in, but the wind is cross-onshore from the east at 16 mph with risk of storms. For a reef break like Takegashima, this is heavy, ultra-powerful water. This is strictly for the experts, and the wind is not helping.
Friday and Saturday (August 7-8) stay big, with swell heights around 12ft to 13ft and periods of 12-13 seconds. Strong energy remains, but the wind is cross-onshore and the forecast is poor. It’s a frustrating stretch.
Things finally ease up on Sunday morning (August 9). The swell drops to 3ft from the east with a 13-second period. The wind is only a light 3 mph cross-onshore. The surf is only marginal, but it’s a step in the right direction.
Here is the one true standout. Tuesday morning (August 11). Swell is 4ft from the south, with an 11-second period. The wind goes completely glassy – 0 mph from the southeast. That is going to be the cleanest, most beautiful window of the whole forecast. The wave energy is moderate (433), but that ocean will be like glass. For a smaller swell, the quality will be there.
After that, from Tuesday afternoon through the end of the forecast (August 12-21), the swell drops to under 2ft most of the time. There are a couple of glassy moments on the 12th and 17th, but the energy is very low. The rest is dominated by poor surf conditions or very ordinary, small waves.
So the verdict: The first few days have size but no quality. For the hardcore crew, Thursday might offer a raw, powerful but messy session. For the rest of us, Tuesday August 11 morning is the only clear winner – clean, glassy, and manageable. The following week looks flat and not worth planning around.

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.
