The Lowdown

Alright, this is Rusty, giving you the long-range look at Tainohama. We’ve got a wild 16-day stretch ahead, so let’s get into it.

The first few days are a slow burn, but don’t write it off yet. The water is sitting at 84°, which is a touch warmer than normal for this time of year, so you’ll be comfortable in just a shorty.

We start off on Saturday, the 1st of August, but honestly, it’s a total dud. Tiny 1ft swell from the SE with a short period, and the wave energy is weak (33). Not worth getting wet. Sunday the 2nd is still pretty marginal. The swell picks up a fraction to 2ft in the morning, but the wind is a cross-off from the NNE, which at least cleans it up. The afternoon sees a bit more size at 4ft with a long 16-second period from the ESE, and the energy jumps to moderate (579). It’s still a scrappy one for the advanced crew only.

Monday the 3rd gets a bit more interesting. The morning swell is 5ft from the ESE at 16 seconds, and the energy is now strong (1277). But the wind is onshore, making it a messy affair. The afternoon drops to 5ft but the onshore picks up, so it’s not great.

Now, here’s where it gets wild. Tuesday the 4th, the morning swell is a solid 10ft from the ESE with a very long 17-second period. The energy is very strong (5330). But the wind is light and onshore, so it’s a bit of a washing machine. The afternoon though? The swell hits 13ft with the same long period, and the energy is absolutely pumping (15711). The wind is a gentle cross-onshore, but the forecast says the swell is too big for this break. This is strictly for the experts only, and only if they know the reef well. It’s not a beginner’s wave.

Wednesday the 5th is the standout. The morning brings a clean 16ft swell from the SE with a 17-second period, and the energy is massive (14466). The wind is light cross-shore, so it’s holding up well. The afternoon is even bigger, with 18ft from the SE and even more energy (18166), but the wind shifts to a light cross-onshore, putting a few ripples on the face. The swell is too big for the break, so this is a big-wave, expert-only session. This is the best on offer for the whole period – if you’ve got the stones for it.

Thursday the 6th is still pumping, with a 21ft swell from the SSE in the morning and a clean cross-off wind from the NE. The energy is off the charts (22001). Again, too big for the break, but for the few who can handle it, it’ll be a day to remember. The afternoon drops to 20ft but gets choppy with a cross-onshore.

After that, things start to settle down. Friday the 7th has a 16ft swell in the morning with light cross-shore wind, but the afternoon turns onshore and messy. Saturday the 8th drops to 10ft with a shorter period, and the wind is a mix of cross-on and onshore. By Sunday the 9th, we’re down to 6ft with a risk of thunderstorms and onshore winds. Not good.

From Monday the 10th all the way through to Friday the 14th, it’s a long, flat spell. The swell is small, the period is short, and the wind is mostly onshore or cross-onshore. The energy is weak. It’s a total write-off for a solid 5 days.

Then, we get a little flicker of hope on Saturday the 15th. The morning shows 4ft from the E with a 14-second period and glassy conditions. The energy is moderate (800). It’s a small window for a clean little session. The afternoon stays marginal.

The final day, Sunday the 16th, is the second real standout. The morning brings 7ft from the ESE with a 14-second period, clean cross-off wind from the NE, and solid energy (2041). The forecast says excellent conditions for experienced surfers. This is a proper session for the early crew.

So, to wrap it up: the best of the best is Wednesday the 5th and Thursday the 6th for the big-wave hellmen, and then Sunday the 16th for the rest of the experienced crew. Don’t bother with the long flat spell in the middle.

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.
