The Lowdown
Alright folks, Rusty here. Let’s get into it.
Right off the bat, I gotta be straight with you – the next week and a half is pretty flat. We’re looking at a long, quiet stretch from Thursday the 23rd of July all the way through to Monday the 3rd of August. Swell energy is weak, barely cracking 100 (46 to 170 range) most days, and the waves are tiny – just 1ft to 2ft. It’s surfable, but it’s small and ordinary. You’d be scratching for anything rideable. The water temp at Tainohama is sitting at 83°, which is a touch warmer than normal for this time of year.
The one bright spot, and I mean the only proper standout in this whole 16-day window, arrives on Wednesday the 5th of August. That’s when things finally fire up. A solid 7ft groundswell from the ESE with a long 16-second period pushes in, and the combined energy jumps to a serious 2494. That’s strong wave energy, no doubt. The wind is glassy in the morning – dead calm – so the reef at Tainohama will be clean and lined up. The swell direction (ESE) matches the optimum S direction pretty well for this exposed reef break. Be aware, though, this is an advanced spot, and with 7ft+ waves, it’s only for the experienced crew. The long period means it’ll be a proper groundswell, with plenty of power and longer lulls between sets, making the paddle out a bit easier if you’re smart about it. Crowds are possible here sometimes, so expect a few others with the same idea.
The days leading up to it (Tuesday the 4th) are building but messy with onshore wind, so don’t bother. By Thursday the 6th and Friday the 7th, the swell drops fast and the wind picks up, so that Wednesday morning window is your one true shot.
The long gap from the 23rd to the 3rd is a bummer, but when the swell finally shows up, it’s a proper little pulse. Keep an eye on it, but don’t hold your breath until that first week of August.
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.
