The Lowdown

Hey, Rusty here again, giving you the same outlook but in feet, miles per hour, and Fahrenheit.

So the start of this run is totally dead for Tainohama. Nothing but small, messy cross-onshore slop through Monday and the first part of the week. It's a total flat spell until something finally shows up.

First sign of life hits on the morning of Friday the 18th. It's still early, but there's a clean 8ft swell out of the East (8-second period) with glassy conditions. Wave energy is moderate (1032) and it's aimed at experienced surfers. Not the big standout, but it’s the first real wave after a long wait.

Now we're talking. Saturday the 19th morning has Tainohama pumping with a solid 10ft groundswell from the ESE and a very long 15-second period. That's proper energy (4398). Winds are clean, cross-off from the North. This is a standout for the experienced crew. But with that size and that long period on a reef, it's a heavy, freight-train wave.

The absolute standout is Sunday the 20th. The morning session is looking unreal. A powerful 12ft swell from the Southeast with a long 14-second period, pushing through a massive wave energy of 5497. The wind is offshore and moderate out of the North. This is expert territory, but if you can handle it, the conditions are exceptional. The swell direction is exactly what Tainohama wants.

Then Monday the 21st is another monster. A 16ft swell out of the SSE with a 15-second period is insane energy (11139). The morning has light offshore winds, setting up an epic, clean, giant day for experts. This is as good as it gets on paper, but it's deep in the forecast, so keep an eye on it. The afternoon goes downhill with strong onshore wind.

After that massive pulse, the swell drops off hard. From Tuesday the 22nd, we get gale-force offshore wind that makes paddling impossible, then it just fades into tiny, clean but flat conditions for days. There's a little energy bump late on the 26th and into the 27th, but the wind turns bad. The real payoff comes at the very end. On Monday the 28th afternoon, it's glassy again with a huge 10ft southerly groundswell with a very long 16-second period. That’s a massive 7318 in wave energy and exceptional for experts again. The 29th looks similar but windier.

So bottom line: you wait through a long, flat start. Lock in Sunday the 20th morning and Monday the 21st morning if you're an expert. The last week holds some serious potential, but it's a long way out, so treat it as promising but less certain.

Stay safe out there.
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.
