Alright, Rusty here again. Let me break down Tainohama in feet.
This is a reef break that lights up with a good S swell. Not a spot for groms or learners – when it gets going, it's for advanced crew only.
Monday the 6th is a total dud. You've got a weak 2ft SE swell, a long 15-second period groundswell, and the combined energy is only 199. Not worth the walk down the cliff.
Things start cooking Tuesday the 7th. Morning offers a 3ft SE swell (15-second period) with a nice cross-off breeze. Energy is 650. Then Tuesday afternoon is the first real standout: glassy conditions, the swell pushes to just under 4ft, the period hits 16 seconds, and the energy skyrockets to 1122. Clean, punchy, and lined up on the reef. That's the one.
Wednesday the 8th sees the swell jump to 8ft of SE groundswell (17-second period), but the wind turns onshore. The energy is 4466 – moderate – but the quality tanks. Thursday and Friday are huge: Friday morning the swell hits 13ft from the S with an 18-second period and an energy reading of 10148. That's a monster, but it's all blown out. That setup is more for kite surfers than paddle guys.
Saturday the 11th stays big with 13ft swell and energy around 9765, but the wind holds onshore.
Sunday the 12th is the real turnaround. Morning drops to a still-sizeable 8ft SSW swell (15-second period) with cross-off winds. Energy is 2685, and conditions are described as excellent for experienced surfers. That reef will hold those long-period lines perfectly. That's a standout.
Into week two, Monday the 13th has a clean morning with 5ft S swell (12-second period) and glassy water – nice little session. Sunday the 19th is another winner: glassy again, a 7ft ESE swell, but shorter period at 8 seconds. Still, the energy is 1063 and the conditions are clean, so expect punchy, fun waves for the advanced crew. Crowds are possible around Tainohama, so get there early.
In short: skip Monday the 6th. Hit Tuesday arvo the 7th for the first real clean swell, and circle Sunday the 12th and Sunday the 19th for the best combo of size and glassy conditions. The middle days are for experts who don't mind a blown-out wave.
Rusty, signing off.

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.
