The Lowdown
Alright, let's get into it. This is Rusty, and I've been staring at the charts for Tainohama.
Honestly, the first week or so is a tough slog. We've got a lot of small, weak swell and less-than-ideal winds. There's a real quiet spell from about the 18th through to the 23rd of July where the wave energy just bottoms out, with values falling as low as 26 (weak energy). It’s a proper lull.
The first real glimmer of hope, and the standout for this whole outlook, is the morning of Sunday, the 26th of July. The energy starts to build, but the morning of Sunday the 26th is where it starts to come together. We're looking at a 1ft swell from the SE with a period hitting 15 seconds. That's a long-period groundswell. For a reef break, that could be magic. The wind is glassy from the ESE at just 3 mph. That's absolute perfection for clean, smooth faces. It won't be big, but the quality of the wave should be outstanding. It’s the only session in the whole run with a real "expect good surf conditions" tag on it.
The other one to circle on your calendar, but with a bit more caution, is the Monday morning, the 27th of July. It’s still glassy with that sweet NE breeze at 3 mph, and the swell bumps up to 2ft from the ESE, with a very long 15-second period. The combined energy climbs to 293 (moderate wave energy), feeling stronger and more consistent. Tainohama is a reef, so that long-period SE swell will wrap in nicely, offering some clean lines.
Now, for the experienced crew, the afternoon of the 30th of July is the big one. The swell jumps to 7ft from the SE, with a 15-second period. That’s big for this spot, and combined with a massive energy reading of 1888 (very strong wave energy), it’s expert territory only. The wind is a clean cross-offshore from the NNE at 6 mph, which will groom it. This is for the brave, not the beginner. The size and power will make for some heavy, sucky reef waves.
For beginners, there is nothing safe on offer. The few small swells are either too inconsistent or come with poor winds. Best to wait for the glassy mornings from the 26th onward if you're an intermediate.
Overall, the first week is a write-off, but the final few days of July have a couple of true windows of excellence, especially for those who like their waves clean and lined up.

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.
