The Lowdown

Righto, let’s have a look at what’s headin’ our way for Tainohama.

First thing to say is the start of this run is a bit of a write-off. We’re talkin’ Monday and Tuesday with next to nothing worth paddlin’ out for – tiny little 1ft to 2ft slop, onshore winds, and cross-onshore junk. Not worth wetting your suit. The water temp’s sittin’ at 84°, which is a touch warmer than usual for this time of year, so at least it’ll be pleasant when you’re sittin’ out there waitin’.

Wednesday the 2nd shows a bit of life – swell bumps to 4ft from the SSE, but with a short 8-second period and cross-on winds, it’s still messy. Not worth getting excited about.

Now, Thursday the 3rd morning is where we get our first proper nod. The wind swings offshore from the north, light breeze, and that 4ft SSE swell cleans right up. The combined energy is moderate at 241, and it’s actually clean. It’s a reef break, so that offshore flow will groom it nicely. Not a standout, but a solid little session if you’re keen.

Friday the 4th sees the swell kick up to 6ft from the south, with a moderate cross-offshore breeze. The energy jumps to 618 – solid moderate. But with heavy rain around and a cross-off wind, it’s more of a “maybe” than a “definitely.” Still, clean enough for the advanced crew.

The real standout? Sunday the 6th. That morning, we’ve got glassy conditions – not a breath of wind – with a 6ft swell from the ESE at 10 seconds. The combined energy is a strong 857, and the forecast says “very good surf conditions.” This is the one to circle. Nice clean lines, manageable size, and that reef will be working beautifully. For the advanced surfer, it’s gonna be a cracker.

Monday the 7th is nearly as good – still glassy, 7ft from the ESE with an 11-second period, energy up at 1181. That’s strong, powerful swell. It’s a touch bigger, so better for experienced surfers only. But both days, the wind is offshore or glassy – pure gold.

After that, things get a bit messy. Tuesday the 8th drops right back to small 2-3ft, and the wind goes cross-off. Not bad, but nothing special.

Wednesday the 9th brings a return of clean 3ft swell with offshore wind, and then Thursday the 10th pumps up to a big 13ft from the SE with a long 13-second period. Energy is massive at 5037. That’s a heavyweight swell – experts only. The wind is cross-off, so it’ll be clean, but at that size, this reef is gonna be heavy and take some serious commitment. Worth a look if you’ve got the stones.

From Friday the 11th right through to the end of the window on the 15th, it goes pear-shaped. We’re talkin’ onshore gales, strong wind, heavy rain, and stormy conditions. The swell stays big – 7ft to 10ft – but it’s all blown out and choppy. The energy readings are huge (1086 to 3473), but with that onshore wind, it’s more of a kite-surfing setup than a paddle session. No good for rhythm surfing.

So to sum it up: the best of the best is Sunday the 6th and Monday the 7th. Glassy, clean, powerful swell, and the reef is gonna be firing. Thursday the 10th for the big-wave crew only. Everything else is either too small, too windy, or both.

Stay safe, keep your line, and I’ll catch ya out there.

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.
