The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Takegashima over the next couple of weeks. It’s a bit of a slow burn, but there’s some serious size on the horizon if you’re patient and know what you’re doing.
Right now and through the first weekend, it’s pretty flat and gutless. We’re talking tiny 1 ft to 2 ft swell from the SE, with periods all over the shop. The water temp is about average for this time of year, nothing strange there. Sunday morning the 2nd of August starts to see a little life, with a 2 ft ESE swell but it’s blown out by a 6 mph onshore wind. The energy is still weak (328). Not worth paddling out for.
Sunday afternoon, things start to rumble. That ESE swell bumps up to 4 ft with a very long 16-second period, and the energy is climbing into moderate territory (624). The wind is a light cross-onshore, so it’ll have a bit of texture. It’s still just marginal.
Monday the 3rd of August sees the swell building fast. Morning has 5 ft of ESE groundswell at 16 seconds, and the energy is getting solid at 1431. Wind is still light cross-onshore, so not clean but not a total mess. Monday afternoon hits 7 ft with a 17-second period and energy of 2367. The wind goes cross-shore, but with a risk of t-storms. This is getting juicy, but it’s still a bit raw.
The standout window starts Tuesday the 4th of August. Tuesday morning throws down 10 ft of ESE swell, 18-second period, and the energy is roaring at 5987. Wind is light and cross-onshore, but with that much power, it’s going to be big. Tuesday afternoon is the real gem: 12 ft, still 18 seconds, energy blasting at 8042, and the wind is light cross-shore. This is proper groundswell. That long period means the waves will have serious shape and power, but at a reef like Takegashima it should handle it beautifully. This is big, expert-level stuff.
Wednesday the 5th of August, the swell peaks. Wednesday morning shows 15 ft at 18 seconds from the SE, energy through the roof at 13532. Wind is onshore, so it’ll be bumpy. Wednesday afternoon hits 18 ft from the SE, same 18-second period, energy of 19224. The comment says it’s too big for the break. At this size, only absolute experts with a death wish should even look at it.
Thursday the 6th of August is still oversized. 25 ft swell on both sessions, energy over 33,000. Winds are moderate onshore, making it a total washing machine. This is not surfable for anyone. Same goes for Friday the 7th of August, with 20 ft to 22 ft and choppy cross-onshore winds.
Saturday the 8th of August, the swell drops back to a still-chunky 10 ft in the morning but with a short 9-second period, energy down to 1645. Wind is still cross-onshore. Afternoon picks up to 15 ft from the S with a 16-second period and energy of 9827, but the wind is moderate cross-onshore, so it’s choppy.
After that, it fades fast. From the 9th through the 14th of August, it’s mostly poor, with tiny swell and onshore winds. There’s a tiny glimmer on the 13th of August with 3 ft from the E, 12-second period, and glassy conditions in the morning. Energy is weak (311), but it’ll be clean. That’s a small, long-period groundswell – better on the reef than a beach break, but for most folks it’ll be too small to get excited about. Crowds are possible here on a day like that.
So, the short story: The first few days are a write-off. The best surf is Tuesday the 4th of August, specifically the afternoon. That’s the standout – massive 12 ft SE groundswell with an 18-second period, light cross-shore wind, and a ton of energy (8042). This is for advanced surfers only. The second best is Monday the 3rd of August afternoon, with 7 ft from the ESE at 17 seconds. After that, it’s all downhill into flatness. No other true standouts in the second week.
Stay safe, and don’t get caught inside on that Tuesday session.

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.
