Alright folks, Rusty here with a look at what’s coming up for Tainohama. Gonna be a bit of a mixed bag, but there’s some solid days if you play your cards right.
First up, we’ve got a big pulse of swell rolling in. Starting Wednesday the 8th, we’re looking at a building trend. It’s a bit of a rough start though – Thursday morning the 9th sees a 8ft SSE swell, but the wind is onshore and it’s a bit of a washout. Not the cleanest. Thursday afternoon the swell pushes up to 10ft from the SSE, but that cross-onshore wind is making things choppy. This is serious size, over 8ft, so it’s really only for the crew with serious experience.
The real standout window kicks off Friday the 10th. Friday morning we’ve got an 12ft south swell with a solid 17-second period, and light onshore wind. That’s a big, powerful groundswell. Wave energy is pumping, so there’s plenty of grunt. This is an advanced-only affair at that size, but the potential is huge. The wind stays light through Saturday morning the 11th, with the swell holding at 13ft from the south and that long 17-second period. Saturday morning is the pick of the whole run – the wave energy is absolutely thumping. It’s massive, clean, and powerful. Perfect for the experienced chargers at this reef.
The water temperature is sitting at 77°, which is a bit colder than normal for this time of year by about 3°. Worth a slightly thicker spring suit.
After that peak, things start to drop. Sunday the 12th is still solid at 10ft from the SSW, but the wind is variable. By Sunday afternoon, the swell is easing to 8ft and getting a bit lumpy. The drop-off continues into Monday the 13th. The big swell is gone, but Monday morning you get a little glassy 4ft south swell. Not huge, but with glassy conditions, it’ll be clean and fun if you just want a paddle.
From there, it gets small and quiet. Tuesday the 14th has waist-high glassy conditions, but the energy is weak. Wednesday through Friday the 17th is mostly flat or tiny, with poor wind. That’s about a four-day stretch of nothing special.
Then, just as you’re about to give up, we get a little pulse. Saturday the 18th morning goes glassy again with a 4ft swell from the ESE, then Sunday the 19th morning sees a 8ft ESE swell with a clean, offshore north wind. That’s a late-week highlight. The wind holds clean from the north through Monday the 20th and Tuesday the 21st, with solid 4ft to 6ft swell. Tuesday afternoon fades a bit, but it’s still clean. This is a promising run for the second week, but it’s a long way out, so keep an eye on it.
So, to boil it down: Friday morning the 10th through Saturday morning the 11th is the absolute stand-out. Big, long-period south swell with manageable wind. If you’re an expert, that’s your window. For the second week, Sunday morning the 19th offers the most promise with clean offshore wind and a solid 8ft ESE swell.
Stay salty, folks.

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.
