The Lowdown
G’day surfers, Rusty here. Let’s talk about what’s coming for Tainohama.
We’ve got a proper slow start with tiny, pretty average surf for nearly a full week. Honestly, from Monday the 27th of July right through to Sunday the 2nd of August, it’s all pretty ordinary – wave heights are hanging around 1ft to 2ft with weak combined swell energy (mostly under 200). There’s a couple of glassy moments in there on Monday afternoon and Wednesday morning, but the swell’s just too small to get excited about.
A few mornings offer a clean little ripple with cross-off winds, but you’d be pushing it to call it a proper session. Monday the 27th morning has a 1ft SE swell (14 sec period, moderate energy at 172) with a cross-off breeze, so you might get a knee-high wave if you’re keen.
Water temp is sitting at 84°, which is a touch warmer than normal for this time of year – pretty nice.
Now the real story starts from Monday the 3rd of August. That’s when the place lights up. Monday morning sees a jump to 4ft from the ESE with a 15-second period, combined energy hitting 601 – that’s moderate but building quick. The wind is glassy, so expect clean, well-shaped lines. This is good for intermediate to advanced surfers.
Tuesday the 4th of August morning steps it up to 7ft ESE, 17-second period, with strong energy at 2573. Cross-off winds from the NE keep it clean. That’s solid, powerful groundswell – longer gaps between sets, which makes paddling out a bit easier. At this size, it’s pushing it for beginners; better suited to experienced surfers.
Wednesday the 5th of August morning is the standout. You’ve got 8ft from the ESE, 17-second period, combined energy screaming at 3767, and glassy conditions. That’s big, clean, powerful swell. It’s for experts only at this size – amazing waves if you’ve got the skills.
Thursday the 6th morning holds at 10ft ESE with cross-off winds, but it’s getting big. Thursday afternoon sees 12ft with 16 mph cross-off winds – still clean, but it’s definitely big-wave territory.
Then Friday the 7th of August morning is absolutely pumping – 15ft ESE, 17-second period, energy over 11,800, with light cross-off winds. That’s exceptional, but it’s strictly for expert surfers. Friday afternoon jumps to 18ft with 18-second period – it’s likely too big for the break by then.
Saturday the 8th and Sunday the 9th are huge – waves over 30ft to 34ft – way too big to paddle surf safely. That kind of energy (over 63,000) is more for tow-in or just watching from the cliff.
From Monday the 10th of August, the swell drops back to 4ft to 10ft, but winds turn onshore or cross-onshore, so quality fades. Tuesday the 11th afternoon has short-period, messy 6ft with onshore wind – not worth it.
Bottom line: Tainohama’s best window is Monday 3rd to Thursday 6th of August mornings, with Wednesday the 5th morning being the absolute pick. It’s a reef break, so those long-period ESE swells will wrap in nicely, but at 8ft it’s for experienced surfers only. Crowds are sometimes an issue here, so expect a few locals out. The water’s a touch warmer than usual, which is a nice bonus.
Stay stoked.

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.
