Alright folks, Rusty here with a look at what’s on the cards for Tainohama over the next couple of weeks. Gotta be straight with you – it’s not exactly firing straight out of the gate, but there’s a couple of serious windows for the experienced crew if you’re patient.
The first few days are a write-off, so don’t bother paddling out this weekend. We’re looking at weak, messy surf with onshore winds and rain through Saturday and Sunday. The combined wave energy is barely registering at 34 to 67, so it’s a total non-event for surfing.
Monday (July 6th) isn’t much better, with onshore wind and the energy climbing a touch but still poor.
Now, Tuesday, July 7th is where it gets interesting – and this is the one to circle on the calendar. Morning and afternoon both see clean conditions with a cross-offshore breeze from the NNE and NE. You’ve got 5 ft to 6 ft of swell coming from the southeast with a very long 17-second period (groundswell). This is proper, powerful energy – combined wave energy hits 1452 and then 2108. The catch? This is an advanced reef break, and that size and power is for experienced surfers only. That long period southeast swell can really unload on a reef like this, offering some proper shaped waves but also some serious juice. Expect some crowd too, as it’s a spot that gets busy sometimes.
Into Wednesday (July 8th) and Thursday (July 9th), the swell just gets bigger – hitting 10 ft to 12 ft and energy levels climbing to 5,905 and then 6,868. But the wind turns onshore again, and the surf is described as marginal with questionable tide conditions. This could be a beast, but messy.
Friday, July 10th is another standout for the big-wave chargers. Morning sees 15 ft of south swell with a 17-second period, and the combined energy is an enormous 10,982. The wind is a light onshore, so it won’t be glassy, but for a big-wave reef, that’s a serious groundswell. Saturday (July 11th) holds similar size and energy, still big and onshore.
After that, things start to drop. Sunday, July 12th morning offers a real window for the experts again – 8 ft of SSW swell with that 14-second period, but here’s the kicker: glassy conditions. Dead calm. This will be clean and powerful, but at that size and on a reef, it’s expert territory. Energy is still high at 2521.
The following week, from Monday July 13th onward, the swell fades and the energy drops. Monday morning sees a small, clean 4 ft wave with glassy winds – more manageable, but ordinary. Tuesday (July 14th) and Wednesday (July 15th) mornings are also glassy, but only 3 ft and 2 ft of swell. These are small, clean days but nothing to write home about. The rest of the week into the weekend (July 16th to 19th) drops away into tiny, onshore junk with very low energy – 39 to 133. Not worth a paddle.
The water temperature is sitting at 25°C, which is about average for this time of year – no surprises there.
So, the bottom line: the first few days are a bust. The absolute standouts are Tuesday, July 7th with clean, 5-6 ft long-period swell for the advanced crew, and Friday, July 10th for the big-wave specialists, despite a touch of onshore wind. Don’t sleep on the glassy session on Sunday, July 12th morning either.
Stay safe out there.

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.
