Table - best surf conditions forecast for Tainohama over the next 16 days.
G'day, Rusty here. Let me talk you through what's shaping up at Tainohama over the next couple of weeks.
Alright, we've got a big pulse of southerly groundswell coming through to start the period, but honestly, with how this break lines up, it's a bit of a mixed bag. The wind is mostly onshore or cross-onshore for the first few days, so it's a bit of a struggle to find clean conditions despite the size. The water temp is about average for this time of year, nothing out of the ordinary to report there.
Thursday the 9th is a write-off. We've got a building 8ft swell from the SSE with a long 15-second period, pushing combined wave energy of 3506 (moderate to strong), but it's onshore and the forecast is marginal. Not worth paddling out.
Friday the 10th sees the swell bump up to 12ft from the S, period still at 17 seconds, and the combined energy is even bigger at 6993 in the morning and 7486 in the afternoon. Wind is onshore though, and it's still looking marginal. This is big, powerful stuff, over 8ft, so it's strictly for the experts. Saturday the 11th is the standout of this first week. The morning has a 13ft swell from the S with a 17-second period, combined energy rocketing up to 10270 (strong to very strong). The wind is still onshore, but the overall quality is the best we'll see for a few days, scoring a 7. This is big, heavy, groundswell—experts only, but if you're game and the tide works, it could be a session to remember. The afternoon stays solid at 13ft from the SSW.
Sunday morning the 12th offers a brief window of hope. The swell drops to 10ft from the SSW, 16-second period, and we get glassy conditions. That's a major positive, the combined energy is still strong at 4280, and it's described as excellent for experienced surfers. This is the cleanest the big swell will be all week. The window is short, though, as the afternoon turns cross-onshore and choppy.
Monday the 13th drops right off. Morning has 5ft from the SSW, 12-second period, combined energy down to 705, and it's glassy. It's surfable, but the score is low. The afternoon gets smaller, 4ft, and cleaner but not much push.
From Tuesday the 14th through to the end of the first week, it fades out fast. Small, weak swell with poor to marginal conditions. A few glassy windows on the 17th and 18th, but with combined energy under 130 and tiny wave heights around 2ft, it's barely a ripple.
Now for the second week, it gets interesting again. Through the middle of the week (19th to 20th), small ESE windswell tries to build, but it remains marginal and onshore. Then, Tuesday the 21st of July morning is a massive alert. The forecast is calling for a 15ft swell from the SE with a 14-second period, and combined energy of 15615. That's enormous—way too big for this break, the report says it's predicted to be too big. No one should be out there unless you're suicidal. Wednesday the 22nd morning offers a quieter window with a 7ft SE swell and glassy conditions, combined energy of 803, and is considered very good surf. That's one to keep an eye on, but remember it's a long-range forecast.
The last few days of the period (23rd and 24th) fade back to small, cleanish conditions with cross-offshore winds, but the swell is tiny, under 4ft. Not much to get excited about.
So, the clear standout is Saturday the 11th of July morning for the sheer size and power, if you're an expert and can handle the onshore wind. The other highlight is Sunday the 12th of July morning, when the big swell meets glassy conditions for a brief, clean session. For the second week, the Wednesday the 22nd morning is the most promising but with lower confidence this far out. There are a lot of flat, poor days in between, so pick your window carefully.
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.
