The Lowdown
Alright, let’s get into it, folks. First up, we’ve gotta be real with you. The next few days are looking pretty flat and sad around Tainohama. There’s a bit of swell, but it’s short-period, weak, and the winds are mostly junk. It’s going to be a bit of a waiting game, so don’t rush out for the next few days.
The first real sign of life comes on Tuesday the 15th in the morning. We’ve got a glassy morning with a little waist-high SE swell. The energy is still modest (206), but at least it’s clean. It’s a small window before the wind goes onshore later. Wednesday the 16th is similar, more of the same small, clean stuff early. It’s surfable, but nothing to write home about. You’ll be scratching for waves.
Keep your eyes on the prize for the end of the week. The real standout is shaping up for Friday the 18th in the afternoon. The swell jumps, and the period gets long—19 seconds! The energy is strong (723) and it’s coming from the SE, which is good for this spot. This is when it starts to get proper.
But the true big one, the one to circle on the calendar, is a week from now. Saturday the 19th and Sunday the 20th of September are looking firing. Saturday morning is going to be clean and solid, head-high plus, with a strong groundswell. The energy readings are huge, over 3900. This is proper juice. It’s going to be hollow and powerful. Sunday morning is similar, big and glassy, with another massive energy reading (3659). This is the pick of the window, no question. This will be for experienced surfers only; at 8ft, it’s not a day for the faint of heart.
The swell stays solid into the next week but the winds get a bit more tricky. The morning of Tuesday the 22nd looks like another good one, with clean 7ft surf from the S, but the arvos get chopped up by the SE winds. The following Wednesday the 23rd looks like a write-off with a strong onshore.
Now, for the truly special stuff. If you are a proper expert, keep an eye on Thursday the 24th in the afternoon. That’s the day the forecast loses its mind. We’ve got a huge 8ft swell with a 16-second period, and it’s glassy. The energy reading is a massive 5237. This is a serious, once-in-a-while kind of setup.
And then, hold onto your board. The morning of Friday the 25th. The forecast is showing a giant, clean, 15ft groundswell with light offshore winds. The energy reading is off the charts at 10452. This is an absolute beast of a day. It is big, it is powerful, and it is only for the truly elite. This is as good as it gets, but you’d better know what you’re doing. Saturday the 26th stays massive but might be a bit too big even for this break. Like the file says, the swell might be too big for the spot.
So, to sum it up: the next four days are a bust. The window of opportunity opens this weekend, but the true standouts are the mornings of the 19th, 20th, and the huge days on the 24th and 25th. They're a week away, so take the long-range hype with a pinch of salt, but the potential is enormous. Stay patient, be ready, and don’t be late.
Rusty out.

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.
