The Lowdown

Alright, Rusty here with the lowdown on the local lineup. One spot to talk about, so let’s keep it simple.

The first week is a bust. From Tuesday the 18th through Sunday the 24th of August, don't bother. It’s tiny, weak, and the wind is all wrong. The wave energy is barely breaking 90, and the water’s a warm 83°F, which is about average for the time of year. Just flat and choppy.

Then, Tuesday the 25th of August, Tainohama starts to show some life. A clean SE swell rolls in, 3ft in the morning with a long 16-second period and a clean cross-offshore breeze from the NNE. By the afternoon, it’s pushin' 5ft with the same clean lines. Energy climbs past 500 and then over 1000.

The real standout run begins Wednesday the 26th through Friday the 28th of August. Wednesday morning has 8ft from the SSE, 14 seconds, and clean cross-off winds. Thursday the 27th is even better: 8ft with a 15-second groundswell and clean conditions, energy over 3000. Thursday afternoon steps it up to 10ft, 16 seconds, still clean. This is big, powerful stuff—best for experienced surfers at this reef.

Friday the 28th of August is the absolute winner. Morning brings a massive 12ft from the S, 16-second period, with a gentle offshore breeze. Wave energy is a huge 5647. Conditions are exceptional for experts. The afternoon holds the same. After that, it starts to back off a bit through the weekend, with more onshore winds.

Early September still has some punch. Monday the 31st has 7ft from the SSW with a 15-second period but some cross-shore wind and stormy weather. Tuesday the 1st of September brings fresh offshore winds, 6ft in the morning and a punchy 10ft in the afternoon, though that afternoon swell is shorter period. Wednesday the 2nd cleans up nicely with 7-7ft ESE groundswell and fresh offshore breezes.

So, first week is a dud, but from Tuesday the 25th of August onwards, Tainohama is on. The best day by far is Friday the 28th—big, clean, and powerful. Get after it if you’re up for it.

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.
