The Lowdown
G’day, Rusty here. Let’s have a look at what Tainohama has on offer.
To be straight with you, the next week is slim pickings. We’ve got a solid run of tiny, crummy surf from this Sunday the 19th right through to Saturday the 25th. Swell sits around 0.7ft to 1ft, mostly from the ESE with a short period—energy is weak (combined swell energy 19–142). Most of it is blown out by cross-onshore winds or just gutless. There are a few glassy mornings on Tuesday 21st, Wednesday 22nd, and Thursday 23rd, but there’s almost nothing to ride. Not worth paddling out.
Things finally stir late on Sunday the 26th. A glassy afternoon with 1ft S swell and a long 15-second period, combined swell energy climbing to 173. Then Monday 27th morning is the first proper highlight: a clean 3ft swell from the south (15-second period) with a cross-off NNE breeze—that’s clean surf (combined energy 921). By Monday afternoon it’s glassy and the swell jumps to 6ft from the south, period dropping slightly to 14 seconds but still solid, energy up to 1352. That’s excellent for experienced surfers.
Tuesday 28th morning is the standout of the whole run. Glassy conditions, 7ft south swell, 14-second period, and a combined energy of 2047. That’s a powerful, clean groundswell. Bit much for beginners—over 8ft is only for experts, so this one sits in that intermediate-to-advanced sweet spot. The direction (S) is a good match for Tainohama’s optimum. Crowds are possible here, so get in early.
The afternoon on Tuesday 28th gets messy with a 12 mph south cross-onshore, and from Wednesday 29th onward it’s a choppy write-off through to the end of the period. Gusty cross-onshore winds and building swell, but no quality. The week starting Monday 3rd August sees 7ft to 8ft ESE swell with a very long 18-second period, but the onshore wind and chop ruin it. Good for kites, not for paddling.
Water temp is 82°, which is bang on average for this time of year.
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.
