The Lowdown
Alright, let’s break it down. Only Tainohama is on the menu, and it’s a reef break. For the next ten days or so, it’s mostly dead flat and not worth your time. From July 22nd through the 31st, we’re talking ankle-biters: 1ft to 2ft from the ESE or SE. Combined swell energy is weak, mostly under 200. Winds are light, and we get some glassy spells—like Friday the 24th morning and Tuesday the 28th—but the waves are so small, it’s barely a ripple. Water temp’s about 82°, pretty average for the time of year, nothing weird.
Big gap in good surf here. July 22nd through the 31st is mostly a skip.
Then August kicks in. Saturday the 1st shows some pulse: 3ft from the ESE in the morning with clean cross-off wind, and energy jumps to 494. Saturday afternoon brings 3-4ft from the east, glassy, energy of 732. Now we’re talking. The real standout is Sunday the 2nd: 5ft from the east, 18-second period, strong cross-off from the NNE. Combined energy hits 1457 to 1657. That’s a serious groundswell with very long period, and Tainohama’s reef will make it hollow and fast. Over 5ft, it’s for the experienced crew only. Monday the 3rd is similar—5ft from the east, 17-second period, clean cross-off wind, energy of 1559. Another cracker.
So the call is clear: skip this entire week. The standout is Sunday and Monday morning, August 2nd and 3rd, at Tainohama. Big east groundswell, clean conditions, and a reef that knows what to do with it. Crowds are likely, so don’t sleep in.
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.
