The Lowdown
Alright folks, Rusty here. Let’s take a look at Tainohama over the next couple of weeks.
Right now, the water’s sitting at about 84°, which is a touch warmer than normal for this time of year – you’ll feel that difference straight away.
We’ve got a slow start on the cards. Sunday and Monday are offering up some small, weak swell with mixed winds, nothing to get excited about. The combined energy is low to moderate, so you’re better off waiting.
The real story begins to build on Tuesday, 4th August. The swell picks up with a moderate energy and the waves start to get some size. By Wednesday morning, 5th August, we’re looking at a standout session. It’s going to be a big one – around 16ft from the ESE with a very long period of 17 seconds. That’s proper groundswell. The wind is light and cross-offshore, which will keep the face clean. This is a reef break, and with a long period swell like that, it’s going to line up beautifully. But listen – at 16ft, this is strictly for experts. The combined energy is through the roof. Thursday the 6th is even bigger, with around 21ft swell and the energy absolutely pumping. That’s an absolute beast, and again, only for those with serious experience. The wind stays favourable on the Thursday morning, but it gets choppier later.
Friday the 7th is still huge, around 23ft, but the winds start to turn messy. The swell is still pumping, but the quality drops. Over the weekend of the 8th and 9th, the size backs off a bit, but we’re into risk of thunderstorms and the wind is cross or cross-onshore, so the surf will be a bit of a mess.
After that, the swell drops away significantly. By Monday the 11th, we’ve got a brief moment of interest on Tuesday morning the 12th, with a 4ft SSW swell, light offshore wind, and clean conditions. But the energy is low. From the 13th onwards, it’s small and weak. There’s a glassy moment on the 14th morning, but the swell is tiny. The rest of the period into mid-August is flat or onshore slop.
So, the standout here is Wednesday morning, 5th August. That’s the one to circle. Thursday the 6th is also huge but similar conditions. After that, the second week is quiet with small, weak swell and poor winds.
This is Rusty, signing off.

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.
