The Lowdown

Alright folks, Rusty here. Let’s get into it for Tainohama.

We’ve got a massive pulse of energy showing up, but this isn’t an easy run. The opening days are a tease with a big, clean window that’s strictly for the experienced crew. Things get messy for a long stretch after that, and you’ll need to be patient for the next real opportunity.

The first real action kicks off right now, on Tuesday, 4th August. The ocean is packing some serious punch – the combined energy is massive (7009). We’re looking at a 10ft swell out of the ESE, but the wind is on it from the south, so it’s going to be a bit of a battle. Not the best way to start.

Wednesday, 5th August morning is the standout. This is the one. The swell jumps to a solid 15ft from the ESE, and the key is the wind – a clean cross-offshore from the NE. The water temp is about average for this time of year. The energy is absolutely pumping (10647), and the conditions are described as clean. This is exceptional for experts only. The wave period is a very long 16 seconds, which is a classic groundswell. That kind of period can make a beach break a bit straight, but for a reef setup like Tainohama, it’s going to be a proper, grinding machine. The afternoon keeps the size up at 16ft from the SE, but the wind swings a bit cross-shore. Still, a massive day for the right crew.

From Thursday, 6th August onwards, it gets too big and messy. The swell is hitting 20ft, and the wind goes cross or cross-on. The energy readings are through the roof (17647, 19205), but it’s a wall of white water and a cross-chop. This is a serious safety issue and not one for the paddle crew. The wind and tide are favorable for the swell being too big, which means it’s probably a better show for the kite surfers.

Friday, 7th August stays massive and ugly. The wind is on it, and the energy peaks at 30006. The swell is swinging from SSE to S, but the quality is poor. By the afternoon, the size drops to 13ft, but the wind is up and it’s choppy.

The rest of the first week and into the second week is a long, drawn-out period of poor conditions. From Saturday, 8th August through to Friday, 14th August, the swell drops from 12ft down to 3ft, but the wind is almost always cross-on or onshore, keeping the ocean choppy and messy. There are a few mornings with cross-off winds and cleaner conditions on the 14th and 15th of August, but the swell is tiny (2ft-3ft) with very low energy (171-242). Not enough push to get excited about.

Sunday, 16th August brings a late pulse. The morning sees a 6ft ESE swell with clean cross-offshore winds and a moderate energy (1105). It’s a good option for experienced surfers. The afternoon is where it gets interesting again – the swell jumps to 13ft from the ESE with a 12-second period, putting the energy at 4639. The wind is still clean cross-off. This is a major, late-period swell, but it’s far out. It’s promising but less certain. The run then gets blown out again on Monday, 17th, and Tuesday, 18th.

The final note is on Wednesday, 19th August morning. The swell is tiny at 3ft, but the conditions are glassy. The energy is minimal (723), but if you have a longboard and want a flat, clean session, it’s a pretty way to end the forecast.

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.
