The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Tainohama over the next couple of weeks.

Right off the bat, it’s a quiet start. We’ve got a bit of a lull on our hands. From Sunday the 26th of July right through until the end of the month, there’s really nothing to get excited about. The surf is tiny, around 1ft to 2ft, and while you’ll get some glassy mornings on the 27th and 28th, the swell is just too weak to push anything decent. The combined energy is pitiful, sitting between 39 and 174 (weak). It’s the kind of flat spell where you’re better off waiting for the next system.

Monday the 3rd of August shows a flicker of life with the swell bumping up to 4ft, but it’s coming straight onshore and the period is a long 16 seconds, which at a reef break like this is a good thing, but the wind is all wrong. The water temp is about average for the time of year, nothing wild.

Now, hold onto your boards, because the real story starts on Tuesday the 4th of August. That morning is a standout. The swell jumps to 7ft from the ESE with a very long 17-second period – that’s pure groundswell energy. The wind is glassy, absolutely dead calm, and the combined energy is a massive 2563 (strong). This is going to be a serious session for experienced surfers. The break is a reef, so that long period will wrap in beautifully. It’s a proper, clean, powerful wave. Just be aware that with the swell over 5ft, this isn’t for beginners, and at 7ft, it’s getting into expert territory.

Wednesday the 5th of August is another big one, but it’s a bit more of a handful. The swell is 10ft from the ESE, period 17 to 18 seconds, and the combined energy is 4600 to 5801 (very strong). The wind is a cross-off from the N, which keeps it clean, but that’s a solid, heavy wave. Definitely for experts only.

The absolute peak of this run looks to be Thursday the 6th of August. Morning session sees 12ft ESE swell, 17-second period, and a combined energy of 7420 (very strong). The wind is a clean cross-off from the NE. That’s exceptional surf for the crew that can handle it. It’s big, it’s powerful, and it’s clean. The afternoon gets a bit wind-affected from the SSE, so get in early.

Friday the 7th of August stays meaty, with 13ft to 15ft ESE swell, but the wind is onshore from the S, so the quality drops. The energy is off the charts – 8909 to 10394 (very strong) – but it’ll be a washing machine. For the brave only.

By Saturday the 8th, it’s still huge at 13ft, but a light cross-on wind from the S keeps it from being perfect. The energy is still enormous (over 9000). Sunday the 9th sees the swell drop back to 7ft, but the wind is a cross-on again, and then it fades quickly into flatness by Monday the 10th.

So, for the best on offer, I’m calling it: Tuesday the 4th of August morning is the pick of the week for a clean, powerful, and manageable big swell. The Thursday the 6th of August morning is the absolute standout for the brave, with massive, clean, groundswell energy. This is a serious window for the experienced crew at Tainohama.

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.
