The Lowdown

Alright folks, Rusty here, with a look at what the ocean's got cookin' for us in the coming weeks.

First off, I’m not gonna lie to you – the next several days are a tough watch. We’ve got a real flat spell on our hands. From now through to the 26th of July, it’s pretty much a washout. The swell is tiny, barely a ripple, with the combined energy sitting in the weak range (42 to 156). The water temp is a touch warmer than normal at 83°, but that’s about the only highlight. You’ll see some glassy mornings on the 21st, 22nd, and 23rd, but with waves around 0.7ft to 1ft, there’s just nothing to ride. You’re better off waxing your board and waiting. The 24th and 26th offer a slight glimmer, but it’s still super ordinary.

Alright, hang in there, because things start to change on the 27th of July. Monday morning, the wind goes light and glassy at Tainohama (a reef break). The swell picks up to 3ft from the S with a nice 14 second period, pushing the energy up to 429 – that’s what we want to see. It’s still small, but it’s clean and building. That afternoon gets a bit choppy with a cross-on wind, so the morning session on the 27th is the pick of that day.

Now, the real standout is Tuesday the 28th of July. Get ready. We’re looking at a solid 8ft south swell, with a 15 second period – that’s proper groundswell. The combined energy rockets to 2623. The conditions are glassy in the morning, making for excellent surf for experienced surfers. This is a powerful, long-period swell, which for a reef break like Tainohama means well-shaped, clean lines. It’s going to be a ripper, but it’s definitely not for beginners.

The swell keeps pumping through the 29th, 30th, and 31st, with heights hitting 12ft and more, and the energy going through the roof, up to 5535. But the wind turns onshore and gets strong, chopping it up. It stays big, over 12ft, and the cross-on wind makes it a messy, challenging beast. Unless you’re a real charger with a big board, those days are for watching.

Into the first week of August, the swell is still huge on the 1st, with 13ft, and the energy is a massive 8088, but the wind is straight onshore. It’s a messy, dangerous situation. The 2nd is similar, with the wind keeping it rough. By the 3rd of August, it starts to drop back, but the wind is still onshore, so it’s not a great option.

So, to wrap it up: The absolute best bet is the morning of Tuesday, 28th July. That’s the one. Clean, glassy, and a solid 8ft S groundswell at Tainohama. Mark it on your calendar. The morning of the 27th is a good warm-up. Everything else is either flat, blown out, or too big to handle.

Stay stoked, and keep your eyes on the horizon.

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.
