The Lowdown
Grab your board and let’s get into it. The next couple of weeks kick off with a bit of a slow burn, but there’s one proper standout window that’s worth circling on the calendar. Takegashima (the reef) is the only spot on the radar, and it’s a consistent, exposed reef that loves easterly swell. Water’s sitting at 84°, which is a touch warmer than normal for this time of year—nothing crazy, just a little extra warmth in the water.
Saturday the 1st is flat and forgettable—tiny 1 feet of SE swell with poor, weak waves. Not worth the paddle. But Sunday the 2nd brings the first real hint of life. Glassy conditions with a light ENE breeze, and the swell bumps up to 2 feet in the morning, then jumps to 4 feet in the afternoon as the period stretches out to 16 seconds. That’s proper groundswell, and the energy reads 683—moderate, but clean. It’s small, but the reef will make it count. Good start.
Monday the 3rd sees the swell build to 5–5 feet, still from the ESE with a 16-second period. Energy climbs to 1272–1498, but the wind turns cross and cross-on, with a chance of thunderstorms. It’s surfable, but a bit messier. Tuesday the 4th is where it starts to get serious—10 feet of ESE groundswell, period 17 seconds, and energy jumping to 5327–6831. That’s strong. But the wind is cross and cross-on, so it’ll be lumpy. Still, there’s plenty of water moving.
Wednesday the 5th is the real standout. Morning: 15 feet of SE swell, period 17 seconds, energy at 11588—that’s a serious pulse. Wind is light and offshore (ENE at 6 mph), so the face should be clean. This is the best of the whole run. The afternoon holds at 16 feet but the wind swings cross-on, so the morning is your window. This is expert territory—over 8 feet—so only the experienced crew should even think about it.
Thursday the 6th is huge, and honestly, too big. 20 feet of SE swell, period 16–17 seconds, energy over 20,000. The morning looks onshore and heavy, and the afternoon is stormy. The guidance says it’s too big for the break, and I’d agree—this is getting into “don’t even bother” territory unless you’re a big-wave specialist. From Friday the 7th through to Monday the 10th, it drops but stays messy—13 feet down to 3 feet, with cross-on winds and stormy conditions. Energy fades from 8436 down to 388. Not great.
The middle of the month, from the 11th to the 15th, is a proper lull. Swell drops to under 4 feet, periods shorten to 8–13 seconds, and it’s mostly poor, choppy, and onshore. A few small windows of clean conditions, but honestly, nothing worth getting wet for. It’s a quiet stretch.
Then, on Sunday the 16th, things perk up again. Morning brings 4 feet of ESE swell with glassy conditions and a light SSE breeze—clean, rideable, and a nice little rebound. Energy reads 312, and the afternoon stays clean with a cross-off breeze. It’s not the big stuff from earlier, but it’s a decent way to close out the run.
So, the standout is Wednesday the 5th, morning session—big, clean, and powerful. That’s the one to wake up early for. Everything else is either too small, too messy, or too big. Keep an eye on the 16th as a fun, smaller option. But the 5th is the day.
Catch you out there.

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.
