The Lowdown

Righto, let’s get into it.

We’ve got a solid run of surf coming up at Tainohama, a reef setup that needs a southerly swell to really light up. The water’s sitting at 84°, which is a touch warmer than normal for this time of year, so the summer feel is hanging on.

The action kicks off Sunday the 6th of September in the afternoon. Swell is 6ft from the ESE with a 10-second period, and the wind is blowing offshore from the N at 16 mph. The wave energy is moderate at 735, and the conditions are clean. This is a standout – a proper, punchy reef wave with offshore wind. It’s advanced only though, so this one’s for the crew who know what they’re doing. Crowds are possible here, so get in early.

Monday the 7th holds in there. Morning has 5ft from the SE with a gentle cross-offshore breeze, clean and consistent. Energy drops a touch to 600, but still good. The afternoon picks up a little to 6ft, still clean. Tuesday the 8th stays clean, with offshore winds in the morning and a 4ft swell, then cross-offshore in the afternoon with 5ft. Good, workable surf.

Wednesday the 9th is a mixed bag. The morning gets a bit of a southerly cross-onshore wind, and the swell jumps to 7ft from the SSE – that’s getting big, pushing into expert territory. Energy is strong at 698, but the wind messes with it. The afternoon swings back to a clean offshore from the N at 16 mph, with 5ft from the SSE, so the arvo session is the call.

From Thursday the 10th through Saturday the 12th, the swell backs off. Heights drop to around 4ft and then down to 2ft, with the wind staying mostly cross-offshore. The wave energy is weak, under 150. It’s surfable but nothing to write home about.

Sunday the 13th sees a bit of a pulse. The morning goes glassy with a 2ft swell from the S, but the period is 10 seconds and energy hits 220, so it’s clean and fun for a small-wave session. The afternoon gets a 4ft from the ESE with an onshore wind, so the morning is the pick.

Monday the 14th has 4-4ft from the ESE with moderate cross-offshore winds, but the conditions are rated as marginal. Tuesday the 15th brings a bigger pulse – 7ft from the ESE in the morning, then 6ft in the afternoon, but both sessions have cross-onshore wind and energy in the 600s. The wave quality isn’t great, and this setup might be more interesting for kite surfing than paddle surfing.

Wednesday the 16th is a highlight. Both morning and afternoon go glassy, with 5ft and 4ft from the SE, period around 8 seconds. Energy is 244 and 200, and the glassy wind makes for clean, inviting waves. This is the best call in the second week – a true glass-off session.

From Thursday the 17th onward, it fades. Swell drops to under 3ft, winds go onshore or cross-onshore, and the energy is weak, often under 100. The weekend of the 20th and 21st is flat, with tiny 1-1ft waves and glassy conditions, but barely rideable. A long stretch of small, poor surf to end the forecast.

Overall, the standout is the Sunday the 6th afternoon session – that 6ft offshore at Tainohama is the pick of the run. For the second week, the glassy Wednesday the 16th is a beauty.

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.
