The Lowdown
Alright folks, Rusty here, switching over to the old-school units. Let’s break down what Tainohama is serving up.
For the first stretch, you’re looking at a lot of nothing. From Tuesday the 21st of July right through the 26th of July, the swell is tiny – think ankle-biters, maybe 0.7ft to 1ft at best. The combined energy numbers are all under 200, which is weak sauce. It’s just not worth suiting up. Water temp is about 82°F, pretty normal for this time of year, so nothing to complain about there, just the lack of waves.
Things start to wake up around Monday the 27th of July. You get a bit of S swell, around 2ft to 3ft, period around 9-10 seconds. It’s surfable, but nothing special.
Now, the real standout hits on Tuesday morning the 29th of July. The wind goes dead calm – glassy as a lake – and a clean 1.7m (about 6ft) SSW groundswell rolls in with a 12-second period. The combined energy jumps to 872, which is a solid, meaty push. That’s a proper reef wave for the advanced crew. Sets will be a little more spaced out with that longer period, but the shape will be there.
The morning of Thursday the 30th of July is another beauty – glassy again with 1.6m (about 5ft) SSW swell and energy at 636. Get out there early before the seabreeze messes it up.
As we head into the start of August, the size comes up, but so does the wind. By Sunday the 2nd of August, we’ve got a big 3.0m (close to 10ft) SSW swell, but it’s blowing onshore and turning it into a washing machine. That’s expert-only, and honestly, it looks better for a kite session than a paddle.
The final highlight is Monday morning the 3rd of August. Another glassy start with a solid 2.0m (7ft) SSW groundswell and energy near 983. That’s the real deal for those who know the reef – clean, powerful, and all yours if you’re sharp.
So, to sum it up: the first week is a total dud. Your best bets are the glassy mornings on the 29th and 30th of July, and the 3rd of August. Everything else is either too small or too messy.
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.
