The Lowdown
Alright, Rusty here. Let's have a look at what's on the menu for Tainohama.
This is a bit of a tough one, lads and lasses. The next couple of weeks look like a real mixed bag with a lot of waiting. The water is sitting at 78°, which is a touch cooler than we'd expect for this time of year, so don't be leaving the wetsuit at home just yet.
The first few days, from Wednesday the 15th through to the weekend, are pretty flat and uninspiring. We've got a few knee-high, 2ft to 3ft swells rolling in from the SSW, but the energy is weak (130-133). The wind is glassy on Wednesday morning, which is a tease, but the swell just isn't there to make it worthwhile. The afternoons get messy with a cross-onshore breeze. By Friday the 17th, it's dropping even further, and we're looking at a long stretch of really poor conditions. Literally from the 17th through to the 24th, the surf is mostly in the 0.7ft to 1ft range with onshore winds and just no power. It's a blank run, plain and simple.
Now, here's where it gets interesting. The forecast is showing a serious pulse of energy arriving around Saturday the 25th. We're looking at a 5ft SSW swell, but the period is a short 6 seconds, so it'll be a bit fat and messy. The real event is shaping up for the following week. On Monday the 27th, we see a 7ft easterly swell with 940 of combined energy, but it's coming straight onshore. That's more of a wind-swell mess than a clean surf day.
The standout window is Wednesday the 29th and Thursday the 30th. This is the one to keep an eye on. A proper S swell is forecast, hitting 8ft to 8ft with a very long period of 13 to 14 seconds. The combined energy is massive, hitting 2016 and then 2618, which is serious. Now, Tainohama is a reef break, which is perfect for these long-period groundswells. It will be thick and powerful. The catch is that the wind is looking onshore for most of it, and the wave comment says "marginal" and "questionable," so it could be a bit of a washing machine. For experts only, that's the window. The morning of the 29th with a light cross-off from the ENE could be the cleanest of the lot, but it's still a big, powerful swell. This is over 8ft, so it's not for the faint of heart, and the crowds at Tainohama can be an issue *sometimes*, so get there early if you're keen.
Basically, the first week is a write-off unless you're happy with a flat lake. The second week, specifically the 29th and 30th of July, is where the big dogs will be out. It's a promising but distant call, so keep your fingers crossed the wind plays ball.
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.
