The Lowdown
Right, let’s have a look at what we’ve got for Tainohama over the next couple of weeks.
First up, we’re looking at a real slow start. Honestly, the first few days are flat and not worth paddling out for. Monday the 27th of July has tiny 1ft waves from the southeast, but the conditions are clean enough in the morning with a light cross-off breeze, and by the afternoon it goes glassy – still, it’s just not doing anything. The combined swell energy is only 172, so it’s weak. Tuesday and Wednesday aren’t much better, with poor surf and a lot of onshore or cross-on wind. You’ll be waiting.
There’s a long gap here. Nothing worth getting excited about until Sunday the 2nd of August. Even then, the morning only offers 1ft from the ESE with a long 16-second period, but it’s small. The afternoon bumps up to 3ft with the same direction, period still long at 15 seconds, and the energy jumps to 268, but it’s cross-on and marginal. Not the day to clear the diary.
Now, the real standout is shaping up for Wednesday the 5th of August, early morning. That’s when we finally get some proper size – 6ft from the ESE, a long 16-second groundswell, and a solid 1768 combined energy. The wind is coming from the NNE at 10 mph, which is a clean cross-off breeze at Tainohama, and the report calls it excellent surf for experienced surfers. This is the one to aim for. With the swell this big (over 5ft), it’s not for beginners, and that long period means it’ll have power and shape. It’s a reef break, so that long-period groundswell will wrap in nicely. Best of the whole outlook, hands down. The water temperature is about average for the time of year, nothing unusual.
Thursday the 6th of August still has size – 6ft in the morning – but the wind shifts more onshore and the conditions get messier. Not a write-off if you’re desperate, but not the gem Wednesday is.
Later in the second week, it fades again. By the 8th and 9th of August, we’re back to tiny waves and onshore winds. The 11th of August shows a small improvement with 3ft from the east and a clean cross-off breeze, but it’s nothing special.
So, in short: the first week is a write-off, then Wednesday the 5th of August is your best bet – solid 6ft groundswell, offshore wind, and a clean reef. Don’t get too excited about the rest.

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.
