G’day, Rusty here. Let’s have a proper look at what’s comin’ through for Tainohama.

Right now, it’s pretty flat and sloppy out there. We’ve got a long stretch of poor surf that runs from Saturday the 4th right through the weekend and into Monday the 6th morning. That’s a solid few days of nothin’ worth paddlin’ for. The water temp’s sittin’ at 76°, which is about 1° cooler than usual for this time of year – basically average, no big deal.

Things finally start to show a pulse on Monday the 6th afternoon. The wind goes glassy, and we see a little 3 ft swell from the SE with a period of 14 seconds, combin’ energy of 342 (moderate). Tiny, but clean. You might catch a grovel on a longboard.

Tuesday the 7th morning is where it gets interestin’. The swell jumps a bit – 3 ft from the SE again, but the period stretches out to 17 seconds, and the combined energy is a strong 1106. The wind is light and cross-off from the NE. That’s a clean setup at this reef break. It’s not huge, but for an advanced surfer, those long-period lines will wrap in nicely on the optimum S swell direction.

Wednesday the 8th sees things ramp up fast. Morning swell is 10 ft from the SE with a 17-second period and massive energy at 6074. That’s a lot of water movin’. Wind’s a bit cross-on though, so it’ll be a little bumpy. Afternoon it hits 12 ft from the SE, 18 seconds, 6914 energy. Still with some onshore breeze. This is big – only for experts.

Then comes the standout. Thursday the 9th morning. Glassy as a mirror, wind from the SSW at 0 mph. Swell holds at 12 ft from the SSE, 16-second period, and energy of 7158. That’s exceptional for experienced surfers. Clean, powerful, and long-period groundswell. Just remember, at a reef break, that long period means long lulls between set waves, but when they come, they’ll be thick and lined up.

Friday the 10th morning might be the absolute best on offer. 13 ft from the S, 17 seconds, energy at a huge 9553. Glassy conditions again. That’s proper, heavy, expert-only surf. Tainohama will be pumpin’. The afternoon stays solid at 13 ft with energy over 10,000, but the wind turns cross-on and roughens it up a bit.

Saturday the 11th and Sunday the 12th still hold good size – 12 ft droppin’ to 8 ft – but the wind gets onshore or glassy in the mornings. Sunday the 12th morning is worth a look: 8 ft from the SSW, 14 seconds, glassy, and 2260 energy. That’s excellent for experienced surfers, much more manageable than the earlier 13 ft days.

From Monday the 13th onward, the swell fades fast. Down to 4 ft and below. A few glassy moments on the 15th and 16th mornings, but only 2 ft. Not much to get excited about. A few clean, tiny waves for a longboard if you’re desperate.

So, the one-two punch for this outlook is: Thursday 9th morning and Friday 10th morning at Tainohama. Both are glassy, big, long-period groundswell from the S/SSE – exactly the direction this reef wants. These are expert-only, heavy, and clean. Crowds? This spot can get ‘sometimes’ busy, but with waves this size, it’ll thin out quick.

If you’re not an expert, aim for Sunday 12th morning – still solid, cleaner, and much more doable.

No other breaks in the region to talk about – just Tainohama holdin’ the line.

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.
