The Lowdown
Alright, folks, Rusty here. Let's have a look at what's on the cards for Tainohama over the next couple of weeks.
We're in for a real mixed bag. The first few days are pretty small and not worth getting wet for, but hold onto your board – things are about to get proper heavy. This is a reef break that only handles advanced surfers, and when the big stuff rolls in, it's gonna be strictly for the experienced crew.
Sunday the 2nd is a write-off, with tiny 2ft to 4ft ESE swell and messy cross-off breezes. Not worth the paddle out. Monday the 3rd morning wakes up a bit with a clean 5ft swell from the ESE and light NE cross-off winds. The energy is building (1198) and the conditions are clean, so this is a decent warm-up for the crew who know the reef.
Then things get real. Tuesday the 4th morning sees a 10ft ESE groundswell with a long 17-second period. The combined energy is already pumping at 5629, and while the wind is a light cross-onshore, this is big, powerful water. By Wednesday the 5th, we peak. Wednesday morning has a clean 15ft SE swell with a 17-second period, cross-shore ENE wind at only 3 mph, and energy at a massive 12900. This is the standout of the whole forecast. The swell direction is off the optimum for this spot, but the sheer size, the glassy cross-shore wind, and that long-period energy make it a proper, heavy, expert-only session. Wednesday afternoon is even bigger at 16ft, but the wind picks up slightly.
Thursday the 6th stays massive with 20ft surf, but it's starting to get a bit lumpy with stronger cross-onshore winds. This is still expert territory, but the quality drops a touch. By Friday the 7th, the swell holds around 16ft, but the wind goes onshore and we get thunderstorms rolling through. It turns into a bit of a washing machine, honestly, probably more interesting for the kite crew on a beach setup than for paddle surfing.
The following weekend and into the new week sees a steady drop-off, with messy, onshore winds and a lot of chop from the 8th through the 11th. There's a brief window on Wednesday the 12th morning with clean, gentle offshore winds from the N and a small 3ft S swell, but the energy is only 248 – it's a clean but tiny session.
Now, for the second week, keep an eye on this. Friday the 14th morning looks promising. A clean 7ft ESE groundswell with a light N cross-off breeze. The period is 11 seconds, the energy is 1007, and the conditions will be glassy. Saturday the 15th morning stays solid with a 7ft ESE swell and clean cross-off winds, but it does get bigger and choppier in the afternoon. Sunday the 16th morning has a 10ft E swell with clean cross-off winds – that’s a big, expert wave, and it looks good. Then Monday the 17th morning offers a clean 8ft E swell with light offshore breezes. These last few days are promising, but they're a long way out, so stay tuned.
Alright, that's the long-range picture. Keep your eyes on that Wednesday the 5th and that Friday the 14th window. Get out there if you're brave enough.
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.
