The Lowdown
Alright, Rusty here. Let’s break it down. We’ve got a decent run of surf at Tainohama, a reef that’s for the advanced crew only. The water’s sitting at a warm 85°F, which is a touch warmer than usual for this time of year.
The show starts on Sunday morning the 6th. Clean 7ft swell from the ESE with a 9-second period. The energy’s moderate at 675, and with a light cross-offshore breeze, it’s going to be a fun, punchy morning. The afternoon holds steady with 7ft from the ESE, 10-second period, and even more energy (894). The rain might roll in, but the waves will be worth it. This is the standout session – clean, solid, and offering some proper reef walls.
Monday the 7th sees a drop to 5ft from the SE, but the wind swings offshore in the afternoon. That’s a gorgeous call for the afternoon session – clean, offshore lines on a dropping swell. Energy is still respectable at 418. Tuesday the 8th is a mixed bag. The morning is small at 4ft, but the afternoon jumps back to 5ft from the S with a 10-second period and a solid 653 energy reading. The wind goes light and cross-off, making for another clean session.
Then Wednesday the 9th brings a pulse. The morning has 8ft from the SSE with energy hitting 1011 – that’s strong wave energy. Wind is onshore though, so it’ll be a battle. The afternoon cleans up nicely with a 7ft swell from the SSE and a glassy cross-off wind. That afternoon window is the one for the bigger-wave crew.
After that, the swell fades. Thursday the 10th through Saturday the 12th sees waves dropping to under 3ft, with short periods and low energy (under 200). It’s ordinary, small, and not really worth the paddle.
Sunday the 13th brings a little life back – 3ft from the S but with a long 11-second period. That’s a groundswell, and on a reef like Tainohama, it’ll draw some nice lines. Energy is 321, and the wind is light cross-off. A decent session for the patient surfer.
Monday the 14th has a bump in the afternoon to 5ft from the ESE, but the wind is cross-off and the period is short at 8 seconds. It’s a marginal call. Tuesday the 15th sees a 5ft swell from the ESE with a 10-second period, but the wind goes cross-onshore in the afternoon and the energy jumps to 1034. That’s strong wave energy, but it’ll be choppy and messy. A kite surfer might get more out of it than a paddle surfer.
From Wednesday the 16th onward, it’s a long, slow fade. Waves drop to under 3ft, periods get short, and energy tanks below 100. By the 18th, we’re looking at 1.0ft waves with a glassy wind but no power. There’s a 6-day gap of poor to no surf from the 16th right through to the 21st. The 19th, 20th, and 21st are all tiny, weak, and not worth a second look.
So, the best of the forecast is Sunday the 6th – all day clean, chest-to-head high waves with solid energy. The Wednesday afternoon the 9th is the runner-up for the bigger wave hunters. After that, chalk it up to a fun first week and a flat second week.
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.
