The Lowdown
Alright folks, Rusty here. Let’s have a look at what Tainohama’s got cookin’ for us over the next couple of weeks. It’s a bit of a slow burner, but there are some proper moments to get excited about.
Right off the bat, Thursday the 3rd is pretty average with a cross-on breeze and only 4ft of short-period SSE swell. The water’s sitting at 84°, which is a touch warmer than normal for this time of year. Not much to write home about, so we'll sit tight.
Friday the 4th sees a little more size, around 5ft, but that strong cross-off wind is gonna make it messy. Not the best.
Things start to look up on Sunday the 6th. The morning offers 5ft from the ESE with a gentle breeze, clean lines. But the afternoon is where it’s at: 7ft of east swell, period bumping up to 10 seconds, and the wind drops to a slight air. The wave energy is solid at 844 (moderate). This is a standout session – clean, punchy, and just the right size for a good go.
Monday the 7th morning is the absolute pick of the week. We get a full offshore breeze from the north, 7ft of ESE groundswell at 9 seconds, and it’s glassy clean. The energy is strong at 716. This is a proper session for the advanced crew – long period, well-shaped waves. Just be aware, this break can see a crowd sometimes.
Tuesday the 8th afternoon is another beauty – 6ft from the SE, 10-second period, light breeze, very clean. Another one to pencil in.
Now, a heads-up for Wednesday the 9th through Friday the 11th: the wind plays games, swinging onshore at times, so pick your windows. Thursday the 10th morning has a 5ft SE swell with a moderate offshore – good for a sneaky session.
We get a dry spell through the middle of the second week, with small, ordinary surf. Then, on Monday the 14th, things pick back up with 4ft clean ESE swell on a light breeze.
Tuesday the 15th morning offers a real treat: 6ft from the ESE, only a 7-second period, but the wind is glassy – dead calm. It’ll be clean, but that short period means it might be a bit walled up at spots. The afternoon jumps to 8ft but the cross-on wind kills it.
The big news is Wednesday the 16th. We’ve got serious size – 10ft in the morning, blowing up to 13ft in the afternoon from the S with a very long 12-second period. The wave energy is massive at 4477 (very strong). This is expert-only territory, and the cross-on wind in the afternoon will make it a beast. Only for the brave.
We finish off the outlook with Thursday the 17th morning – a clean, glassy 5ft from the south. A nice, calm way to wrap it up.
The standout? Without a doubt, Monday the 7th morning. That offshore wind, the 7ft clean groundswell, and the perfect conditions. Get on it.
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.
