The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Tainohama.
The start of the window is a write-off, with tiny, weak, and messy surf. Things start to turn around from Thursday morning, and the real standout window builds from Saturday into the middle of the following week. The water temp is sitting at 84°, which is a touch warmer than normal for this time of year.
Thursday morning, the 3rd of September, is where we finally get a little life. We’ve got a 4ft swell from the SSE, but it’s short period at 8 seconds. The real kicker is the glassy conditions – that light air from the ENE, making it clean. The combined energy is moderate (202). It’s not big, but it’s clean and rideable for the advanced crew.
The best bet across the whole run is Monday morning, the 7th of September. We’ve got a solid 7ft SSE groundswell, pushing in with a 9-second period, and the wind is offshore from the North at 9 mph. The combined energy is strong (809) and it’s going to be clean. This is a standout for experienced surfers. The SSE direction is just right for this reef. Crowds are possible here, so get in early.
The following Wednesday, the 9th, sees a big jump in size. Morning has 10ft from the SE with a 12-second period, and the wind is a clean cross-off from the NNE. The combined energy is massive (2401). This is excellent, but at 10ft it’s experts only. The afternoon backs off a touch to 8ft, still excellent but still for the experienced crew.
From the 10th onward, the wind turns onshore and the quality drops fast. The 15th of September has a very long period 10ft swell from the ESE (15 seconds), but the cross-onshore wind at 12 mph will ruin it. That’s a kite-surfing setup if you’re into that.
So, to sum it up: the first few days are a bust. Your best chance is the clean, offshore morning of the 7th, and the big, clean walls on the 9th for the experts. The second week gets messy and windy, with a few marginal options but nothing to write home about.
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.
