The Lowdown

Alright, Rusty here. Let's get into it.

We've got a solid run of surf on the way at Tainohama, a reef break that's only for advanced crew. The water's sitting at 84.4°, a touch warmer than usual for this time of year, so you might feel that little extra bit of tropical warmth.

The action kicks off this Thursday, the 3rd. Morning glassy conditions with a 3.6ft SSE swell, but energy is moderate (206). It's a bit on the short period side at 8 seconds, but the glassy wind will make for a fun, clean session. The afternoon gets even better: glassy calm, the swell bumps up to 3.9ft, and the energy jumps to a solid 342. Sets will have a bit more push.

Friday the 4th offers a cleaner 4.9ft S swell at 10 seconds under a cross-off breeze, but the energy is ramping into moderate (473). It's a step up in size. Stay alert though, there's heavy rain forecast for the afternoon.

The real standout, the one you've got to circle, is Sunday the 6th. The morning starts with a clean 5.9ft ESE swell and moderate energy (530). Then the afternoon turns on. It goes glassy, dead calm, and a 13.1ft E swell rolls in with energy of 3893, signalling very strong conditions. This is big, powerful stuff for experts only – well over 8.2ft. The period is 10 seconds, offering proper groundswell punch. This is the best of the forecast.

Monday the 7th stays clean with a 5.2ft ESE chop in the morning, but the wind picks up. The afternoon turns fresh offshore from the north at 19 mph, making for some clean, lined-up 4.3ft waves. A very solid session for those who missed Sunday.

Tuesday the 8th and Wednesday the 9th keep the quality high with offshore winds. Tuesday morning has a 6.2ft SE swell (768 energy) and afternoon sees it jump to 7.5ft (1055 energy). That's expert territory. Wednesday goes big again with a 13.1ft SSE swell (3257 energy) in the morning and a 11.5ft S swell (4198 energy) in the afternoon. Both days are clean, but the size is serious.

After that, the window closes fast. There's a gap from Thursday the 10th through to Sunday the 13th where the conditions get messy with onshore winds and smaller, weaker swells. Nothing worth paddling out for.

Then, there's a late-game surprise. Monday the 14th morning brings a glassy 7.2ft E swell with 9-second period and a strong 1066 energy. That's another expert-level, high-quality session out of nowhere. Clean, glassy, and powerful. The afternoon drops back to a clean 4.6ft, still worth a look.

After Monday, it's a slow fade. Tuesday the 15th onward sees the wind turning onshore or cross-shore, and the swell drops right off into tiny, weak waves for the rest of the forecast. The last week is a bust.

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.
