The Lowdown
Alright, Rusty here. Let’s talk Tainohama in feet and miles per hour.
The window kicks off quiet. You’ve got a tiny knee-high wave on Tuesday morning the 28th, but that’s the only real option for the first few days. The water is running about 84°F, which is a bit warmer than normal for the season—nothing extreme, just a touch of tropical warmth.
On the 28th, Tuesday morning is the only lookable moment. Glassy wind, a 2ft SE swell, and the combined energy is a weak 119. It’s surfable but unremarkable.
Wednesday the 29th and Thursday the 30th are even smaller, dropping to 1ft. Energy is in the cellar—down to 50 and 38. There’s a glassy moment Wednesday morning but the waves are barely rolling. This is a flat spell that lasts through the end of July.
Friday the 31st to Sunday the 2nd is more of the same: 1ft to 2ft swells, mostly SE, with energy under 100. The morning of the 2nd does get a slight pulse—2ft, 14-second period from the ESE with glassy conditions and energy up to 151. Still small, but the cleanest of the bunch so far.
Now, the 3rd of August brings a proper change. Swell jumps to 5ft with a 16-second period, energy over 1000, but the wind is onshore and on it. Not clean. The 4th goes bigger—10ft, 18-second period from the ESE, energy hitting 4797. That’s a lot of water moving, but again, the wind is messy and onshore. This is for advanced surfers only.
The real standout is the 5th of August. That Wednesday morning we’re looking at a 16ft ESE groundswell with a 19-second period—combined energy is a massive 16831. The wind is cross-off from the NNE at 15 km/h (about 9 mph), keeping it clean. This is an expert-level day, plain and simple. The swell direction is perfect for Tainohama’s optimum exposure. Crowds are possible, so don’t sleep on it. With that period, the reef will hold it well, but it might be a little too straight for the beach.
After the 5th, the swell drops fast. The 6th through the 10th are mostly onshore slop or blown out, with the odd 3ft to 3ft swell but strong winds wrecking the quality. The 11th and 12th of August offer a return to smaller cleaner conditions—around 3ft to 5ft ESE swell with shorter periods (7 seconds) but cross-off winds and glassy mornings. Tuesday the 11th morning looks like a clean, fun session, and Wednesday the 12th is shaping up for a nice little finisher.
Best on offer: the 5th of August for the massive, clean, expert-level groundswell. Second call is the 12th of August for a clean, smaller day.
Get out there if you can handle it.
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.
