The Lowdown
G’day, Rusty here, checkin’ in from the Tainohama region. We’ve got a bit of a mixed bag comin’ our way over the next couple of weeks, so let’s break it down.
First up, a quick note on the water: the temps are pretty much what you’d expect for this time of year, so no nasty surprises there.
The action kicks off this Sunday, the 6th of September. Tainohama, a solid reef break that takes an exposed S swell, is lookin’ proper. Sunday morning there’s a bit of heavy rain, but don’t let that put you off—we’ve got a clean 7 ft swell from the ESE, with 9-second period. The combined energy is pumpin’ at 854, so there’s plenty of push. The wind is a cross-off from the NNE at 9 mph, keepin’ things clean. This is quality, advanced-level stuff. By Sunday afternoon, it builds to a meaty 8 ft from the ESE with a 10-second period, and the energy jumps right up to 1348. That’s a strong pulse, but make no mistake, this is for experienced crew only—it’s beyond the beginner zone and into expert territory. The wind stays cross-off and clean, so if you’ve got the skills, this is the standout of the whole window.
Monday, the 7th, sees the swell drop a notch. Morning brings 6 ft from the SE, still 10-second period, but the wind picks up to 16 mph from the north, makin’ it a bit of a battle. The energy is down to 668, and it’s only a marginal call. Afternoon’s a bit smaller at 5 ft, and the numbers just don’t stack up for a great session.
Tuesday, the 8th, is small and messy in the morning—4 ft from the SE—but the afternoon offers a surprise. The wind swings light offshore from the north, the swell drops to 3 ft from the south, but with a 10-second period it still has a bit of shape. Combined energy is 400, and the conditions turn glassy and clean. It’s not big, but for a mellow surf on a quiet break, it’s worth a look.
Wednesday, the 9th, we get a fresh blast of offshore wind, strong at 16-19 mph from the NNW. The swell is 6 ft from the SSE, with 8-9 second period, but the wind is so punchy it’ll put a bit of a texture on the face. The energy is moderate at 455-470, and these are days for hardy surfers who don’t mind a bit of chop with their offshore flow.
Thursday, the 10th, is similar but a touch smaller—4 ft to 5 ft—with clean, moderate offshore breezes. The energy drops below 311, so it’s more of a cruiser session.
From Friday the 11th through to around Tuesday the 15th, things go quiet. We’re talkin’ swell heights under 4 ft, with combined energy mostly in the 100-200 range. There’s a few clean moments, like the glassy Sunday afternoon on the 13th with 3 ft from the S and a 10-second period, but honestly, it’s more for a longboard or a sunset paddle than a proper surf session. The 13th is your best bet in this lull—light winds, clean, glassy surface, and a little 3 ft south swell. It’s tiny, but it’s pretty.
Then, from Wednesday the 16th through to the end of the forecast on Monday the 21st, it’s pretty much a write-off. The swell fades to under 3 ft, the combined energy drops below 50 for a few days, and onshore winds or thunderstorms dominate. There’s a tiny bump on the 20th—Sunday afternoon—with a 4 ft short-period SW swell, but it’s only 6 seconds and the energy is a weak 126. Not worth getting excited about.
So, to sum it up: Sunday the 6th is the absolute standout, especially the afternoon with that 8 ft, clean, cross-off swell. That’s the one for the advanced crew. After that, it’s a slow decline into small, clean but marginal conditions, and then a week of flatness and poor wind. Keep an eye on the forecasts; sometimes a blank run like this can turn around quickly for this area.
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.
