Alright, let's get into it. We've got one spot on the radar for the next couple of weeks: Tainohama. It's an advanced reef break, and it's exposed to the south swell. Right off the bat, we see the water is sitting at 25°, which is about 3° Fahrenheit colder than what’s normal for this time of year – so you'll want a thicker spring suit than usual.

The action starts this Saturday the 11th with a big pulse of energy. We're looking at a solid 13 ft S swell, but the wind is all wrong – cross-onshore and choppy. The combined energy is huge at 8486, but it’s not going to be pretty. That swell is too big for most, and the conditions are marginal at best. This is really for the absolute experts only, and even then, it's a battle.

The standout is Sunday the 12th. That's your window. We drop to a cleaner 12 ft from the SSW, but the magic is the glassy wind in the morning. Zero wind. That's a rare treat for a big swell. The wave energy is still massive at 5296, and with that long 16-second period, it's proper groundswell. This is a reef break, so that long period will wrap in beautifully and not just close out. Sunday afternoon stays glassy with a 10 ft swell, which is still excellent for experienced surfers. This is the pick of the whole two weeks – get on it if you can handle it.

Monday the 13th drops to a much more manageable 5 ft in the morning and 5 ft in the afternoon. The wind stays glassy from the NE and SE, so it'll be clean. Combined energy drops to 687, which is moderate, but the 12-second period still has some push. A solid day for a strong intermediate, but not the standout of the weekend.

Through the middle of the week (14th to 18th of July), things fade out fast. Swell drops below 3 ft, the period shortens, and the wind turns onshore or cross-onshore. The energy drops into the double digits – weak stuff. From Wednesday morning to Saturday afternoon, it's pretty much flat and poor.

We hit a dead zone for almost four days there – nothing worth paddling out for.

Then on the 22nd of July, a new ESE swell fills in. This is your second-week hopeful. The combined energy hits 600 on Wednesday morning with a 3 ft swell and a very long 15-second period. That's a long-period groundswell, and with light NNE cross-offshore winds, it should be clean. The direction is ESE, and while the optimum for this break is south, this is still a very good, clean setup. Thursday the 23rd holds at 4 ft with 12-second period and clean cross-offshore winds again. This stretch from the 22nd to the 25th looks promising, though not as powerful or as glassy as that Sunday the 12th.

The 25th and 26th tail off again, with smaller surf and less favorable winds, finishing up with onshore conditions on the 26th.

So, there you have it. The big, clean, glassy Sunday the 12th is your absolute best bet. The late-arriving swell around the 22nd is a solid second act, but that Sunday is the one to circle.

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.
