The Lowdown

Alright, folks, Rusty here with a look at the waves ahead.

We’ve got one standout spot on the radar, and it’s not for the faint of heart. Tainohama is our only game in town for the next couple of weeks, but the window to score it is narrow and it's strictly for the experienced crew. We’re looking at a serious pulse of swell hitting early, with wave energy readings absolutely massive, pushing into the thousands. This thing is packing a punch.

The best of the best comes this Thursday, the 6th of August. Thursday morning is the one to circle. We’ve got a solid 15ft south-east groundswell with a long period of 14 seconds hitting an exposed reef. That kind of power is major. Add in a light north-easterly breeze that’s keeping the surface clean and glassy, and you’ve got the makings of an exceptional session for advanced surfers. The wave energy is right up there at 8087, and this is a rare, almost perfect window.

Now, if you’re hoping for anything smaller and more manageable, you’re out of luck for a while. Thursday afternoon gets even bigger, hitting 18ft with a 15-second period, but the wind swings onshore from the east, putting a bit of a ripple on it. That’s still a massive, powerful wave, but less clean.

After that first day, the quality drops off a cliff. Friday the 7th sees the swell staying big around 15ft, but with a risk of thunderstorms and strong onshore winds creating choppy, ugly conditions. The wave energy remains high at 14094 on Friday morning, but it’s messy and not recommendable. Saturday the 8th brings a slight drop to 8ft, but again, onshore winds and a risk of storms keep things marginal and just not worth the paddle out for most.

By Sunday the 9th, the swell settles down a bit to 8ft but with cleaner light winds, the window for a manageable wave is gone. The rest of the first week is a slow grind of dropping swell and poor conditions.

We hit a quiet period from the 12th of August onwards. The swell drops to small, inconsistent levels, barely reaching 5ft on the 12th with a clean north wind, but the energy is very weak (465). There are a few glassy mornings on the 13th and 14th with tiny 3ft and 2ft waves, but they’re just too small to get excited about. The following week, from the 15th through the 21st of August, is basically a write-off. The swell is tiny, the period is short, and the wave energy is in the low hundreds or less. The winds look okay from the north at times, keeping things clean, but there’s simply no power in the water for a proper surf. For a break like Tainohama, that’s a long, flat run.

So there you have it. Your window for Tainohama is Thursday morning. 15ft, 14-second groundswell from the south-east, and clean. It’s a beast, but a beautiful one. Wait any longer and you’ll be itching for the next pulse.

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.
