The Lowdown
Alright folks, Rusty here. Let’s see what’s on the menu for Takegashima over the next couple of weeks.
First up, don’t even bother paddling out this weekend. We’ve got a tiny, weak swell with a combined energy of only 47, and the waves are just too small to do anything with. The rest of the week kicks off properly on Monday the 24th.
That Monday morning is where it starts to get interesting. We’re looking at a 4ft groundswell from the southeast, with a period of 19 seconds – that’s very long-period energy, which will really wrap into this reef. The combined energy is a solid 1077, and with glassy conditions, it’s going to be a clean, powerful morning. This is an advanced spot, so it’s for experienced surfers only. The wind is dead calm, and the water temperature is about average for this time of year. Monday afternoon, the swell bumps up to 8ft, still from the southeast, with a period of 16 seconds, and the combined energy jumps to 2722. The wind stays light and cross-offshore, keeping the surface clean. This is the standout window of the entire forecast. It’s the best on offer.
Tuesday the 25th is a different story. The swell is huge, pushing 13ft from the south-southeast, with a combined energy reading of 6946. That’s massive, powerful, and dangerous. The wind is light cross-onshore, which is going to put some texture on those big walls. This is expert-only territory, and honestly, the conditions are marginal because of the size and the wind angle. If you’re not a seasoned charger, give it a wide berth. The rest of the week through the 28th sees the swell dropping but staying messy, with a lot of cross-shore wind and rain. The surf is there, but it’s not clean.
Looking into the first week of September, we get another pulse of serious size. Tuesday the 1st of September has 13ft from the east-southeast, with a combined energy of 6191. The wind is light cross-shore, but the size is still only for the very experienced. Wednesday the 2nd of September looks even bigger, with 16ft from the east-southeast, but the wind is onshore from the northeast at 15 km/h, which will make it a messy, dangerous beast. That’s a setup that looks more interesting for kite surfing than paddle surfing.
By Friday the 4th of September, the swell drops right back to a manageable 4ft from the east-southeast, with a period of 8 seconds. The wind goes glassy, and the combined energy is a low 234. It’s calm, but the waves will be short-period and weak. The best of the second week is actually Saturday the 5th of September, with a 4ft swell from the south, a period of 9 seconds, and glassy conditions. The combined energy is 696, and it’s described as “very good” conditions. That’s a nice, clean morning for a paddle, but the swell is on the small side for this reef.
So, the window is narrow. The absolute best is Monday the 24th of August, with that long-period, clean, powerful groundswell. After that, it’s a mix of huge, dangerous conditions and messy, onshore days. The second week has a few clean, smaller moments, but nothing that compares to that Monday peak.
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.
