Alright folks, Rusty here. Let's see what Tainohama is cooking up for us.

This is a tricky one at first. We're looking at a very slow start with only small, junky waves and onshore winds for the first few days. The water temp is about average for this time of year, nothing wild. Then, hold onto your boards, because from late Monday afternoon through Tuesday it really kicks off with a solid groundswell and glassy conditions. But there's a big catch. That window of perfection is short-lived, and after that, we get absolutely hammered by a huge, messy swell that’s only for the brave (or foolish).

The standout, no question, is Tuesday afternoon, July 7th. Tainohama will be absolutely cranking. We’re looking at a solid 5ft swell from the SSE, but the real magic is the period – a massive 17 seconds of long-period groundswell power. Combined energy is at a powerful 1402 (moderate-strong), which is plenty of punch. And with the wind going dead glassy at 0 mph from the ESE, it’s going to be as clean as a pane of glass. This is the pick of the whole forecast, an excellent session for experienced surfers. Sunday the 5th is a total write-off with tiny, onshore junk.

Monday afternoon, July 6th, is the early bird special. The swell picks up to 3ft from the SE with a long 14-second period (combined energy 426), and a light cross-offshore wind from the ENE will keep it clean. Not huge, but a very solid option.

Then things get out of hand. From Wednesday morning the 8th right through to the end of the week, a massive swell hits. By Friday morning July 10th, we're looking at a monstrous 13ft swell from the S with a 17-second period and combined energy hitting a staggering 9865. That’s very strong wave energy. However, it's all accompanied by strong onshore winds. This is strictly for expert chargers only, and even then, the quality is going to be blown out. It might be more of a kite-surfing show than a paddle-surfing session.

By Monday morning, July 20th, things finally settle. The swell drops to a clean 4ft from the S (10-second period) with a nice light cross-offshore wind from the NE. It's the first real sign of life after the onslaught.

So, to sum it up: the first week is a tale of two cities. A total dud to start, one magic afternoon, then a wild, blown-out giant. The second week is a slow, messy clean-up. Don't sleep on that Tuesday.

Rusty out.

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.
