The Lowdown

Alright, Rusty here, and I’ve got the lowdown on what’s cooking at Tainohama for the next couple of weeks.

First off, we’re in for a bit of a slow start, I won’t lie. The water’s sitting at 84°, which is a touch warmer than normal for this time of year, so boardshorts are the go. But the surf? It’s pretty ordinary for the first few days. Thursday the 27th is a write-off with choppy cross-onshore winds, so don’t bother paddling out. Friday the 28th through Sunday the 30th offers small, clean waves in the mornings – glassy conditions with a few ankle-to-knee high runners around 3 ft – but the energy is weak (107 to 166 combined energy). It’s a nice paddle more than a proper surf.

Monday the 31st has a bit more push with a 4 ft swell from the SSE, but the wind is onshore, so it’s messy. Then Tuesday the 1st of September through Thursday the 3rd gets a bit of a bump in size (5 ft to 8 ft), but the wind cranks up from the SE, making it choppy and poor. The energy is moderate to strong (493 to 976 combined energy), but the onshore wind just ruins the surface. This stretch is a hard pass.

Now, here’s where it gets interesting. Friday the 4th of September is the real standout. Morning kicks off with a clean 7 ft swell from the SE, glassy as a mirror, and the energy is pumping (1203 combined energy). This is proper expert territory – too big for beginners – but for the experienced crew, it’s going to be firing. The afternoon gets even bigger, hitting 10 ft with a moderate offshore wind from the NNW, keeping it clean. This is the best of the best on offer.

Saturday the 5th and Sunday the 6th keep the size up (7 ft to 10 ft) with clean conditions and cross-offshore winds. The energy is strong (1125 to 1489). This is still excellent for experts, but the crowd will be there – Tainohama is "sometimes" busy, so expect company.

Monday the 7th drops back to 3 ft with glassy conditions in the morning – a nice recovery session. Then Tuesday the 8th brings a solid 5 ft swell from the south with a clean offshore breeze, and the energy is decent (612). Not a standout, but a good day.

Looking further ahead, Wednesday the 9th of September is a monster morning. You’ve got a 8 ft swell from the south, glassy calm, and a very long period of 14 seconds. The energy is extreme (2708 combined energy). This is a very long-period groundswell, and at a reef break like Tainohama, it’s going to be a special session for experts. The afternoon gets even bigger (13 ft) but gets a bit choppy with cross-onshore wind. The 11th of September also looks massive (13 ft) with a clean offshore flow, but that’s a full week away, so keep an eye on it.

For the whole run, the best options are the morning sessions on the 4th and the 9th. The 4th is the cleaner, more reliable call for experts. The 9th is a promise of something truly special, but it’s a long way out, so don’t book the day off just yet.

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.
