Updates in hr min s Forecast update imminent
Alright folks, Rusty here. We’re checking out a long-range forecast for Tainohama, and it’s a story of two halves. The ocean’s going to fire up something fierce, but a persistent south wind is going to be the main character for most of it, keeping things messy. The water’s running at 77°, which is about 1° cooler than the norm for this time of year – nothing wild, just a slight chill in the air.
The first few days are a total write-off. Monday the 6th is flat with barely any energy (180) and poor conditions, so don’t even bother. We don’t see anything worth a paddle until Tuesday morning, July 7th. That’s the first real highlight. It’s small, only 3ft of southeast swell, but the wind goes glassy, dead calm. The wave energy is moderate (621), and with a 15-second period, it’s proper groundswell. For a reef break, that long period is a gift, meaning clean, lined-up waves. It won’t be big, but it’ll be perfect. The crowds here are *sometimes* an issue, but on a Tuesday morning with tiny swell, you might have it to yourself.
That glassy moment is the peak of the first week. By Tuesday afternoon the wind swings, and from Wednesday the 8th onwards, we get a massive pulse of swell. Energy readings jump to four-digit numbers, hitting over 10,000 by Friday July 10th, with 13ft of south swell. The problem? Every single session from Wednesday morning through the weekend has an onshore wind. The morning of Friday the 10th has the biggest swell (13ft at 17 seconds from the south) and the highest energy (10,553), but the onshore wind makes it a washing machine. That size is for seasoned pros only – well over 8ft.
We do see a flicker of hope later in the window. Saturday July 18th morning shapes up nicely. The swell drops back to a manageable 5ft from the south, and the wind goes absolutely glassy – 0 mph. The combined energy is moderate (791), and the period is a clean 12 seconds. Conditions would be unreal. The real standout, though, is a bit further out: Tuesday July 21st morning. We get 8ft of east swell, period is short at 9 seconds, but the wind is glassy again. The forecast marks it as excellent for experienced surfers. The energy is strong (1,722), and if that east swell lines up with the break’s optimum direction from the south, it could be the best day of the whole run. Keep an eye on it.
So, to sum it up: don’t even look at the water until Tuesday morning July 7th for some tiny, clean waves. After that, you’ll get plenty of size but blown-out conditions through the weekend and into the next week. The two true standouts to circle on your calendar are the glassy morning of Saturday July 18th, and the promising setup on Tuesday July 21st.
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.
