The Lowdown

Alright, this is Rusty, and I’m looking at what’s on the table for Tainohama over the next couple of weeks. Let me tell you, it’s a mixed bag with a serious dose of reality.

First thing, the water temperature here is about average for the time of year, nothing wild.

We’re starting off with a bit of a whimper right now. The first real chance to paddle out comes on Wednesday, August 28th, early morning. The wind will be glassy, and we’ve got a small 3 ft swell from the SSW with a short period of 8 seconds. The combined energy is weak (220), so it’s not going to be a day of power, but it’ll be clean. It’s a reef break, so the short period isn’t a huge issue. Still, expect it to be pretty ordinary.

The rest of that week is a write-off, honestly. The wind is mostly cross-onshore or onshore, choppy, and the energy is weak. There’s a gap of several days where I wouldn’t bother.

Now, looking ahead to the first week of September, things get interesting, but it’s not all good news. On Tuesday, September 1st, the morning shows a jump in swell to 8 ft from the SSE, with a period of 12 seconds. The combined energy is strong (1746), but the wind is a gentle cross-shore, which is decent. The problem is the conditions are described as marginal, and it’s a lot of water moving. That’s more for the experienced crew.

Then we get a big, messy, powerful swell from the 2nd to the 4th of September. Swells are hitting 11 ft to 13 ft, with strong energy (5000-9000 range), but the wind is onshore and strong, making it lumpy and poor. This is kite-surfing territory, not a great paddle surf.

The real standout, and the one that has me a little excited, is Monday, September 8th, in the morning. We’re looking at a solid 16 ft swell from the SE, with a long period of 12 seconds. The combined energy is massive (12864). The wind is gentle cross-shore, which is a huge positive. This is a big, powerful groundswell, the kind that can be a bit too straight for a beach break, but Tainohama is a reef, so that long period will wrap in nicely. This is one for the experts only, as it’s well over 8 ft, but it has the potential to be the best day of the window. The forecast is a week and a half out, so keep an eye on it, but it’s a promising one.

The days after that drop off quickly, with the swell fading and the wind turning cross-onshore again.

So, to sum it up: the next few days are a scratchy, clean but weak start. The middle of the first week is a messy, windy washout. The big standout is Monday, September 8th, morning, for the big wave chargers. For now, it’s a waiting game.

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.
