The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for Takegashima over the next couple of weeks.
Right now, we're looking at a bit of a flat start. The first real chance to get wet doesn't kick off until Monday the 24th of August, so you've got a few days of small, clean dribble to sit out. After that, the week builds into something a lot more serious, especially for the crew who know what they're doing.
Monday the 24th sees the first pulse of proper energy light up the reef. We're talking a solid groundswell from the SE, climbing to 6ft by the morning and 8ft by the afternoon. The period is super long at 16-17 seconds, a real deep ocean pulse. The wave energy is strong at (2584), and you'll feel that raw power. The morning has a slight cross-onshore, but the afternoon is cross-shore, which will clean it up a bit. This one is for the advanced crew only – that size and that period on the reef will be a washing machine if you don't know the line-up. It's *big*.
The standout, and I mean the absolute standout of the whole window, hits early on Tuesday the 25th of August. We get a solid SSE swell with an overhead 15ft of pure power. The swell period is a very long 16 seconds, and the combined energy is massive (10234). This is a proper, groundswell event. The morning has a light offshore from the NE, which for this spot is text-perfect. The reef will be handling that long period much better than a beach break would – it will focus that energy into clean, heavy, barrelling walls. Conditions will be clean with that offshore wind. This is not a day for beginners; over 8ft is expert territory, and this is way over. If you aren't paddling out, you'll want to be watching. The afternoon stays solid but the wind shifts onshore, so the morning session is the one. This is the best on offer.
Wednesday the 26th is a write-off. A storm hits with 30-40 mph winds, turning the ocean into a mess. The swell is still big, but with that wind, it's dangerous and unsurfable. Thursday the 27th has strong offshore winds (28 mph) and a dropping 8-10ft swell. It will be clean but incredibly hard to paddle into, with the wind blowing straight off the land. You’d be a hero to get a wave, but maybe not a smart one.
We get a bit of a lull after that. Friday the 28th has a glassy 5ft swell, but then the wind goes onshore and ruins the weekend. The swell stays small and blocked by onshore wind right through to Monday the 31st of August.
The next real window appears on Tuesday the 1st of September. This is a great, glassy morning with a solid 7-8ft SE groundswell with a 14-second period. The combined energy is strong (2238), and the wind is absolutely glass – dead calm. This will be the most user-friendly, clean, and powerful day for experienced surfers of the second week. Still over the beginner mark, but for the advanced guys and gals, this is a gem.
The end of the window gets out of control again. Thursday the 4th of September has a forecast for a 16-20ft SE groundswell with an 18-second period. The energy numbers are mind-boggling (20304). The file says it will be too big for the break, and for once, that’s the truth. This is planet surf territory, completely unsurfable for anyone. After that, the swell drops off into nothing by Saturday the 5th.
So, to sum it up. The first few days are a non-event. The absolute best session for the big-wave, advanced crew is the morning of Tuesday the 25th of August. The best clean, manageable beast for the experienced surfer is the glassy morning of Tuesday the 1st of September. Be smart out there.
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.
