The Lowdown

Alright, let’s break this down for Tainohama. Rusty here.

The water’s running about 84°F, which is roughly 2°F warmer than the usual this time of year — a bit toasty but nothing crazy.

We’re starting slow. Monday the 24th has some swell, but the wind’s cross-on and the energy’s high at 1288, but it’s not clean. Waves around 4ft from the SE with a long 19-second period — that’s real groundswell, and on a reef that long period can be a good thing. Still, the wind’s messing it up. Not a standout. That afternoon jumps to 7ft, but the wind picks up and it gets choppy — not worth it.

Tuesday the 25th brings 10ft from the SSE, but the wind is directly onshore all day. That’s too big for beginners and with the onshore chop, it’s only for experts looking for a battle. Energy’s strong at 3584 in the morning, but conditions are poor. Skip it.

Wednesday the 26th drops to 7ft, but again cross-on wind and the period drops to 13 seconds. Afternoon gets worse with 25 km/h cross-on and energy down to 1433. Poor.

Thursday the 27th is a write-off — small, choppy, risk of thunderstorms. Energy’s down to 553 and dropping.

Now, here’s a small window — Friday morning the 28th. Glassy conditions, wind’s almost nothing from the SSW, and we’ve got 5ft swell, but the period is short at 8 seconds — that’s windswell, so it won’t have much grunt. Still, glassy is glassy. It’ll be clean and rideable for a good surfer. Energy’s only 467, so it’s moderate, but it’s the best in the first week. The afternoon gets messy again.

Saturday 29th and Sunday 30th mornings are glassy again, but the swell’s tiny — 3ft and 2ft — and energy’s weak (148 and 111). Surfable if you want a longboard cruise, but nothing special. The afternoons are blown out.

From the 31st through to the 1st of September, it’s flat or near-flat. Swell drops below 2ft, energy’s in the double digits. Dead period.

Now, here’s where it gets good. Wednesday morning the 2nd of September — clean, cross-off wind from the NE, and the swell picks up to 3ft but with a 12-second period from the south. Energy jumps to 403 — not huge, but the quality is there. Still small.

The real standout hits Thursday the 3rd of September. Morning sees 5ft from the south, 14-second period, clean cross-off wind from the north. Energy at 1389 — that’s solid moderate-to-strong. This is excellent for experienced surfers. The afternoon holds up with 6ft and clean conditions, though the wind picks up a bit. This is the best morning of the whole outlook for a proper reef session.

Friday the 4th of September morning is also a cracker — 8ft from the south, 13-second period, clean cross-off wind and energy at 2182. That’s strong energy, but 8ft is expert territory, especially on a reef. If you’ve got the chops, the morning window is the top call. But the afternoon gets wrecked by a 30 km/h cross-on and lumpy conditions. Short window.

After Friday, it drops off again. From the 5th onward, it’s messy, windy, and small. The 8th of September has clean cross-off wind and 4ft swell with 12-second period, but the wind is 30 km/h from the north — that’ll be choppy despite being cross-off. Energy’s moderate at 479, but the wind kills it.

So, bottom line: slow first week, then a couple of really good clean windows on Thursday and Friday mornings (3rd and 4th September) for experienced surfers. If you can only go once, make it Thursday the 3rd morning — the combo of 5ft, long-period groundswell, and glassy cross-off wind is the best on offer.

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.
