The Lowdown
G’day, it’s Rusty.
Right now, Tainohama is mostly flat and not worth your time. There’s a long stretch of weak, barely rideable surf to start, and the first real window doesn’t show up until the last week of July. The first standout morning is Sunday, July 26th – before that, it’s a quiet wait.
Thursday, July 16th morning has a small 3ft swell from the SSW with an 8-second period, glassy NE winds at 3 mph, but the energy is weak (120) and the waves are just ordinary. By the afternoon, the wind turns cross-on and it’s poor. From there, we hit a long dry patch. Friday the 17th through Saturday the 25th is a string of tiny, onshore, weak surf – not worth the drive. The spot is fairly consistent but there’s nothing happening.
Sunday, July 26th morning is where things turn. The swell is still small at 2ft from the SE, but the period jumps to 15 seconds – that’s proper groundswell. Winds are glassy out of the ESE at 3 mph, so it’ll be clean. The combined energy is moderate at 211, and the waves are described as “expect good surf conditions.” This is the best session of the first week. Tainohama is a reef break, so that long-period groundswell will shape up nicely. Crowds are possible.
Then the big stuff arrives. Monday, July 27th morning brings a solid 10ft swell from the SSE with a 14-second period, and energy is massive at 4357. Winds are light cross-on from the SSW at 6 mph, so it’s not glassy, but the size is there. Over 8ft, so this is for experts only. The afternoon holds at 10ft.
Tuesday, July 28th is the biggest day. Morning has 13ft from the S at 13 seconds, energy at 5415. Afternoon peaks at 15ft from the S, 12-second period, with energy at 9973 – very strong. Winds are onshore and cross-on, so it’ll be rough, but if you’re a charger, this is the one. Experts only.
Wednesday, July 29th morning eases to a still hefty 7ft from the SSE, 9-second period, but the wind shifts to a light WNW cross-off at 3 mph – that cleans it up nicely. Energy is 946. A good, powerful session for strong surfers.
Thursday, July 30th morning drops to 3ft from the SE, 8-second period, with clean NE cross-off winds at 3 mph and moderate energy at 213 – a fun small morning for a paddle.
The last couple of days fade back into small onshore slop. So the two true standouts: Sunday morning the 26th for clean, glassy long-period groundswell at the reef, and Tuesday the 28th for massive, heavy surf – but that’s only for the brave.
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.
