The Lowdown
Alright folks, Rusty here, lookin' at what Tainohama's got cookin' for us over the next couple of weeks.
Straight up, it’s a mixed bag with some real quiet spells, but a couple of windows where it might just line up. The water’s sittin' at 84°, a touch warmer than normal for this time of year, so the rubber’s optional.
We kick off Saturday the 8th with a waist-high plus 6ft south swell, but the energy is strong at 1392. The issue? A cross-onshore wind is gonna mush it up. Not a great start. Sunday and Monday keep that south swell coming but it’s dropping, energy falling off a cliff. Monday morning the 10th sees a small 4ft south swell with absolutely glassy conditions. The energy’s way down to 568 now, but glassy is glassy. It’s a small clean wave, a good one for a longboard if you’re keen.
Tuesday and Wednesday see the swell drop to knee-to-waist high, with some clean windows, particularly Tuesday afternoon with offshore north-northwest winds grooming a 4ft south-southwest groundswell with a nice 10-second period. Clean but small. Thursday the 13th into the weekend is a dead zone – tiny wave energy (down near 124) and stormy winds. Basically a write-off until Sunday the 16th.
Sunday the 16th and Monday the 17th offer tiny knee-high waves, glassy mornings but super weak (energy under 200). It’s better for a paddle than a proper surf.
Now, if you can wait, the standout window is shaping up for the 21st of August into the 22nd. We’ve got a clean, small S swell, 4ft or so, light winds going glassy and cross-offshore. Energy is moderate, in the 200s. It won’t be bombing, but for Tainohama in a quiet spell, these are the cleanest, most user-friendly days on offer. The morning of the 22nd sees a light cross-offshore from the north-northeast with a 3ft south swell. Clean, small, and perfect for a sneaky session.
The last day in the window, Sunday the 23rd, shows a really long period south-southeast swell of 16 seconds, but it’s only 2ft and hammered by 16 mph winds. The long period will make it look wonky in the cross-offshore chop, and the energy is only moderate. Leave that one.
So, if you’re picking, the 21st Friday morning or the 22nd Saturday morning are your best shots for a clean, small-wave session. Everything else is either underpowered or blown out.
That’s it from me. Stay wet.

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.
