The Lowdown

Ay, what's happenin'? Rusty here. Gotta be straight with ya – the outlook for Tainohama over the next sixteen days is about as exciting as a flat spell in a barrel. We're lookin' at a real lean run, so don't go cancelling any plans just yet.

The water temp is sittin' at a balmy 84°F, which is about 2°F warmer than the norm for this time of year, so at least the wait will be comfortable.

We've got a solid gap from now right through until the morning of Saturday, August 15th, where we finally see a flicker of hope. That Saturday mornin', there's a small SSE swell mixin' in, around 2ft out of the south with a period of 10 seconds. The combined swell energy is a weak 142, so we're not talkin' any power, but the wind is glassy – dead calm. That's a rare treat for Tainohama, and it'll be the cleanest conditions of the whole period. It's a reef break and it's fairly consistent, but with that tiny swell, it's gonna be a knee-slapper at best. Still, a glassy, clean 2ft south swell is as good as it gets right now.

Then we go straight back into a rough spell. From the Sunday through to the next Friday, it's all onshore slop and wind. There's another glimmer on the Saturday, August 22nd, with a glassy morning and a 2ft south swell, but the afternoon sees the swell jump to 5ft on a moderate onshore breeze, which chops it all up. The energy jumps to 331, but with that wind, it's not gonna be pretty.

Beyond that, the last few days of the outlook into late August just look like more of the same – small, messy waves with onshore winds. There's no real standout session to get excited about. Honestly, the whole setup looks like it might be better suited for a kite session than a paddle out, given the constant cross-onshore flow and lack of any real quality.

Stick with it, though. Tides change, winds shift. It won't be this way forever.
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.
