The Lowdown

G’day, Rusty here. I’m just gonna be straight—this stretch we’re in right now is a proper flat spell. Tainohama is a reef break, advanced only, and for the first week we’re looking at tiny knee‑high dribblers with a bit of long‑period SE groundswell, but honestly, nothing to get wet for. The water’s sitting at 83°, a touch warmer than normal for this time of year, so at least it’s nice to float around, but the waves? Barely there.

From Saturday the 25th through to the end of July, we’re trapped in this rut of 1ft to 2ft SE/ESE swell. The combined wave energy is weak – mostly around 52 to 174 (low to moderate). Mornings are clean with light cross‑off or glassy breezes, afternoons often turn onshore or go glassy but the wave height is just not there. Surfable but very ordinary. Not a single standout in that whole block.

We get a small bump around Saturday the 2nd of August – Sunday morning looks okay with 2ft ESE swell, a short 14‑second period, and combined energy up to 232 (moderate). Still small, but the morning’s clean with a light cross‑off. Not a highlight, just a sign that things might wake up.

Now, the real news. The standout window kicks off Monday the 3rd of August. Monday morning brings glassy conditions, 4ft ESE groundswell, period a long 16 seconds, and wave energy jumps to 828 (moderate to strong). That’s the first proper session of the stretch – clean, solid, long‑period lines for the experienced crew.

Then Tuesday the 4th and Wednesday the 5th of August both have mornings that are the best on offer. Tuesday morning: 7ft ESE swell, 16‑second period, cross‑off wind, energy a powerful 2265 (strong). Wednesday morning: 7ft ESE swell, 17‑second period, clean cross‑off, energy up at 2634 (strong). Both mornings are clean and punchy – excellent for experienced surfers. The afternoons get onshore, so hit it early.

The absolute gem in the whole outlook is Thursday the 6th of August. Both morning and afternoon are glassy, with 8ft ESE groundswell, a very long 17‑second period, and combined energy absolutely pumping at 3996 to 4145 (very strong). That’s big, clean, powerful reef surf – expert only. If you’re experienced, this is the day to circle.

Friday the 7th of August still holds size with 8ft E swell, 18‑second period, and moderate offshore wind from NNW – clean but strong. Energy is still massive at 4267 to 4024. Again, expert territory.

After that, the swell drops quickly. Saturday the 8th and Sunday the 9th of August bring back smaller, more manageable 2ft to 3ft swell from shifting directions, with clean to glassy mornings. Good for a paddle, but nothing compared to that mid‑week pulse.

Overall, the first week is a write‑off. The good stuff starts on the 3rd of August and peaks on the 6th and 7th. That Thursday morning glassy 8ft groundswell session is the one to plan for. Crowds are sometimes a thing at Tainohama, so get in early.

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.
