The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Tainohama over the next couple of weeks. It’s a slow start, but there’s a serious pulse of energy heading our way if you can wait it out.

First up, the early part of the week is pretty quiet. Tuesday the 1st and Wednesday the 2nd are flat with poor conditions, so don’t bother paddling out. Thursday the 3rd afternoon is the first sign of life, with a clean 4ft SSE swell. The wind is light and cross-offshore, making for some tidy little waves. The combined energy is moderate at 369, so nothing too pushy.

Friday the 4th sees a slight bump in size to 5-6ft from the SSE, with clean conditions and light to moderate cross-offshore winds. It’s rideable and fun, but still not the main event. The energy is picking up to 544 by Friday morning, so there’s a bit more juice in the water. Saturday the 5th is a mixed bag – morning is clean with 4ft, but the afternoon turns choppy and messy.

Sunday the 6th is a real gem for the first week. The morning has clean 5ft waves from the ESE, and by the afternoon it goes glassy with a 6ft swell. That’s about as good as it gets for a clean, laid-back session. The combined energy sits at 317 in the afternoon – solid, but not out of control.

Now, hold onto your board. The real standout arrives on Tuesday the 8th. A powerful 10ft swell from the ESE rolls in, with strong offshore winds out of the north. The combined energy is an enormous 2604 in the morning, jumping to 4824 in the afternoon. The period stretches to 12 seconds, which is proper groundswell. This is a serious, expert-only day. The waves will be big and clean, but the power is intense. If you’re not an advanced surfer, stay on the beach and watch.

Wednesday the 9th and Thursday the 10th are the absolute peak of the swell window. Wednesday afternoon sees a 13ft SE swell with a 14-second period and fresh offshore winds. The combined energy rockets to 6328 – that’s massive, powerful water. Thursday morning tops it off with a 15ft SE swell, 13-second period, and moderate offshore winds. The energy hits 6054. This is big, raw, and for experts only. The swell direction (SE) lines up well with the optimum direction for Tainohama, which is S, so it’s going to wrap in nicely but with immense power.

Friday the 11th still has a solid 7-8ft swell with clean conditions and gentle offshore winds. The energy is still high at 1374, so there’s plenty of push for experienced surfers.

By the second week, the swell starts to back off. Saturday the 12th is a bit messy with cross-shore winds, and Sunday the 13th morning looks glassy with an 8ft SE swell – a nice window for those who want clean waves without the huge power. The rest of the week is a write-off with onshore winds and dropping energy.

A quick note on the water: it’s running at 84°F, which is a touch warmer than normal for this time of year, so you can leave the wetsuit at home.

So, to wrap it up: the best sessions are Sunday the 6th afternoon for a clean, glassy fun session, and the real heavy-hitter window from Tuesday the 8th through Thursday the 10th for the big, expert-only groundswell. The rest of the week has some okay windows, but those are your standouts. Stay safe out there.

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.
