Alright, Rusty here. Let's talk about Tainohama.

The next week and a half is a real mixed bag. To start, we're looking at a few days of tiny, poor-quality surf, so you might want to leave the board in the shed. Things really start to cook from Tuesday the 7th with building energy, but it comes with some serious size and tricky winds.

For the first one to raise an eyebrow, check out Monday afternoon on the 6th. We've got small 3ft swell from the SE, but the wind goes glassy. That's a major win for clean conditions, making it a good chance for an easy paddle and some fun, if not powerful, waves.

Now for the standout of the whole period. Tuesday the 7th morning is your session. The swell is up to 4ft from the SE, and the wind is a light cross-offshore breeze. The water is around 77°, which is about average for the time of year. The combined energy is moderate (653), and with that 12-second period, the waves will have proper shape and push. This is a classic window for Tainohama to deliver clean, workable reef waves on the south swell. Get out there.

After that, the story changes fast. From Tuesday afternoon the 7th right through to Saturday the 12th, the swell absolutely bombs, hitting over 10ft by Wednesday the 8th and peaking at 13ft on Friday the 10th. The energy numbers go through the roof, reaching over 9000 (9331) on Friday afternoon. But the wind is all onshore or cross-onshore from the south, and the reports note marginal surf quality and questionable tides. This is only for experts, if anyone, and honestly, with that much onshore wind on a reef, it looks like a better setup for kite surfing than paddling out.

Things mellow out by Monday morning the 13th. There's a small window with 4ft swell and glassy conditions, but energy is low (465) and the period drops to 11 seconds. Then it's back to days of poor, small, onshore wind chop. From the 14th through to the 20th of July, it's essentially a blank run of surf. The waves are under 3ft, wind is onshore, and combined energy is weak, often below 200. You’re looking at a long, flat lull with nothing to get excited about.

So, bottom line: your one true standout is Tuesday the 7th morning for clean conditions on a building south swell. After that, it’s either huge and messy or small and flat for the rest of the 16-day window.

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.
