The Lowdown

Alright, looking at this forecast for Tainohama, and I gotta say, it’s a tough stretch for the next 16 days. This is a reef break, exposed to the south swell, and while it’s usually fairly consistent, the quality is just not there for most of the run. The water is at 84°F, which is a touch warmer than normal for this time of year.

We kick off with nothing on Thursday August 27th. Wind is a messy cross-on from the SSW, swell around 5 feet, but the energy is weak at 752, and it’s choppy and lumpy. No good.

Friday the 28th morning is the first real chance. The wind goes glassy, dead calm, and we get a little 3-foot swell from the SSW, but the period is only 8 seconds, so it’s short-period wind swell. Energy is weak at 203. It’s rideable, but nothing special. If you’re itching, that’s your best early window.

The whole weekend from the 29th to the 31st is tiny, weak, and messy. Swell drops below 3 feet, wind shifts, and it’s all cross-on or glassy but with waves too small to bother. Energy numbers are low, between 70 and 254. Nothing.

The first week of September is a washout. Tuesday the 1st sees a bump to 6 feet, then 7 feet, but the wind is howling from the ESE and SE at 15 to 22 mph, cross-on and choppy. Energy jumps to 570 and 840, but it’s ugly. Wednesday the 2nd and Thursday the 3rd get even bigger, up to 8 feet, with energy over 2000, but the wind is onshore and strong at 25 mph. It’s big, but it’s a mess. This is kite-surfing territory, not paddle surfing.

The first real standout is Sunday September 6th. We get a clean window with offshore wind from the north at 15 mph, and a 7-foot swell from the SE with a 10-second period. Energy is strong at 1230, and the conditions are excellent for experienced surfers. This is the best session in the whole outlook. The swell direction (SE) isn’t the perfect S, but it’s close, and that offshore wind makes it clean. If you’re advanced, this is the day.

Monday the 7th morning is also pretty good – glassy wind, 6 feet from the SSE, energy of 620. Very clean, but the swell is smaller and the period drops to 8 seconds. A solid option for intermediates.

The run from the 8th to the 9th turns ugly again, with big swell (12 feet!) but strong onshore winds and energy over 2700. That’s dangerous, messy. Then on Thursday September 10th, we get a surprise – a clean 7-foot swell from the east with a 10-second period, and only a light breeze from the NE. Energy is 1285, and it’s excellent for experienced surfers. But the east swell direction is not ideal for this spot, which prefers a south swell. Still, it’s clean and punchy.

After that, it fades out. The last few days are small and weak.

So the standout is Sunday September 6th, with that 7-foot SE swell and offshore north wind. That’s the one to mark. The secondary good window is the morning of Monday the 7th, and maybe the morning of Thursday the 10th, though that east swell is a bit off.

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.
