Table - best surf conditions forecast for Tainohama over the next 16 days.
G'day, Rusty here. Let's run through what's in store for Tainohama. It's a wild ride this fortnight, with some serious muscle early on, then a long, flat spell.
We start with a big pulse of swell that's only for the experienced crew. The water's sitting at 77°, which is a bit colder than we'd normally expect for this time of year, so you might want a slightly thicker spring suit.
Thursday the 9th has some serious energy in the water, with a combined energy of 3559, but it's a raw 10ft southerly swell. That's too big for most, and it's a bit onshore, so it's not the standout.
The real event is Friday the 10th through to Saturday the 11th. Massive south swell building from 12ft to 13ft, with a very long 17-second period. The energy readings are off the charts – 6993, 7220, then 9677 and 9976. This is a serious groundswell, and because it's a reef break, Tainohama will handle that long period much better than a beachie would. Saturday morning looks the best of this whole run, with glassy conditions on the morning of the 11th. The wind is onshore, but light. This is a powerful, heavy wave for advanced surfers only. If you're not comfortable in big, raw reef surf, stay on the beach.
Sunday the 12th is a little smaller, still a solid 10ft to 8ft south swell, but the morning is totally glassy, zero wind. That's a huge positive. The sets will be clean and lined up, but the energy is still hefty (4556). This is the best window for the experienced surfer who wants a bit more manageable size than the peak.
The surf drops off pretty fast after that. Monday the 13th morning is still fun at 5ft and glassy, but the energy drops to 692. By the afternoon, it's fading.
Then comes the quiet. From Tuesday the 14th all the way through to Friday the 24th, the surf is poor. Waves drop below 3ft, the energy drops into the double digits, and the wind is mostly onshore or cross-shore. There's a few little flickers of life – a glassy morning on the 18th with 4ft, and a glassy Sunday the 19th with 4ft – but the swell is weak and inconsistent. That's a long stretch of nothing. For the main event, everything points to Saturday the 11th morning as the absolute standout, with Sunday the 12th morning as a close second.
Rusty.

Information about the Tainohama Surf forecast
The above surf forecast table for Tainohama provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tainohama can be found by selecting the local surf guide option on the grey menu. Our Tainohama 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 (Tainohama) 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 Tainohama 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.
Tainohama is 21 km (13 miles) from Anan. If you plan a holiday in Shikoku, look for hotels and other accommodation in Anan. Anan has rooms for a wide range of budgets as well as car hire and transport links.
