Right then, let's have a look at what's cookin' for Tainohama. It's a reef break, and this is a spot that really needs the stars to align, and for the next few days, they're not quite there yet.
The early part of the week is a bit of a write-off. Swell is tiny, under 3ft, with poor conditions and onshore winds. It's not worth paddling out for. There's a bit of a lift around Tuesday afternoon the 8th of July with a 7ft swell showing up, but the combined energy is still just moderate (1026), and the wind is light and onshore. You'll be battling a bit of chop. This swell builds through Thursday the 10th, topping out at 13ft on the Friday, but the wind stays onshore, so nothing is clean. The combined energy gets strong, hitting 8399 on Friday morning, but it's messy.
Now, the standout – and I mean the real standout – is Saturday the 11th. That morning is a thing of beauty. The swell is a solid 13ft, coming from the S with a very long period of 16 seconds – that's proper groundswell with heaps of energy (7570). But the best part? It's glassy. Dead flat calm. That's what we live for. For an advanced surfer only at that size, this is an exceptional session. The reef will be handling that long period S swell beautifully.
Sunday the 12th still looks great, with the swell dropping to a more manageable 8ft and the wind glassy again in the morning. Combined energy is still strong (2620). That's an excellent window for experienced surfers.
After that, the swell starts to fade and the wind patterns get a bit more variable. There are a few glassy mornings, like the 13th and 14th of July, with 4ft and 3ft S swells respectively. These will be clean and fun for a smaller board. The combined energy is moderate (around 559 and 255). There's a gap of poor surf after the 14th until the morning of the 20th of July, which shows a 4ft S swell with glassy conditions again, so things might start to pick back up then.
So, the bottom line: Wait for Saturday the 11th of July. That's the day you set the alarm. The reef at Tainohama will be firing with that long, clean S groundswell. It's big, but it's gonna be perfect. The water temp is sitting about 77° which is pretty normal for this time of year, so you'll be fine in a spring suit.

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.
