Right then, let me have a look at Tainohama. It's a reef setup, advanced only, exposed to the south swell. Water temp's sitting at 76°, which is just about normal for this time of year. But the first few days are a total write-off, I'm sorry to say.
We're essentially staring at a flat, windy mess from now until early next week. Friday the 3rd and Saturday the 4th you can forget - weak, short-period slop with onshore wind. Sunday the 5th is no better. It's all poor conditions, and I wouldn't bother suiting up.
Now, something interesting starts to stir on Monday the 6th. We get a bit of glassy, light airs, but it's tiny. The combined swell energy is moderate at best (131 and 237), and its short period, weak swell. Not the one to go for. The real story is the build-up of a solid south groundswell kicking in from Tuesday the 7th. By the morning of Tuesday the 9th of July, we're looking at 12ft of SSE swell with a very long 16-second period and the combined energy is peaking like a beast (6705). The wind is cross-onshore though, which will put some chop on the face. For a heavy reef like this, that's only for the brave, and it's still big enough to be expert-only. The morning of Friday the 10th pushes through 13ft from the south at a 17-second period, an absolute monster. The combined energy hits 8382. Again, strong cross-onshore winds ruin the potential. This is looking more like a big-wave tow-in or even some serious kite action rather than a pleasant paddle.
The standout moment arrives on Sunday the 12th of July. The swell drops back to a more manageable 5ft from the SSW, but here's the kicker: glassy conditions. Flat, still air, and a 13-second period groundswell. The combined energy is a powerful 1413. For a south-facing reef, the direction is right on, so you're going to get clean, lined-up waves. This is the pick of the bunch for any experienced surfer looking for quality. Monday the 13th has a bit more glass but the swell backs off a touch.
After that, the conditions get messy again. We get another clean window on Wednesday the 16th with a 5ft SE swell and cross-off winds in the morning, but the real jewel might be Thursday the 17th of July. The morning offers a glassy 10ft SE swell with a 14-second period. That’s huge for an advanced reef, and the combined energy is a massive 5713. If you're a local charger and the wind holds, that's an absolute dream session. By Saturday the 18th, it's glassy again with an 12ft SSW swell, but the period has dropped. It's still a solid day for experts.
So if you're looking for an all-round incredible session without the biggest danger, get on Sunday the 12th. For the big-wave hunters, keep an eye on Thursday the 17th morning, but it's getting into that long-range window so treat it as a promising prospect rather than a lock. The rest of the time, the winds are mostly onshore or cross-onshore, so you'll be fighting the breeze on an otherwise powerful swell.

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.
