The Lowdown

Alright, let’s have a look at the next couple of weeks for Tainohama.

First up, the water is sitting at 85°F, which is a touch warmer than average for this time of year – not a massive deal but nice for a session without a thick suit.

The opening window this weekend is pretty lacklustre honestly. Saturday the 5th morning is only pushing 3ft from the SSW with a period around 9 seconds. Wind is a light cross-off from the N, so the surface should be clean, but the energy is weak (212). That’s really just a kneeboarder’s dribble. Saturday afternoon drops further to 3ft and conditions turn ordinary. We’ve got a stretch of small, average surf through to Monday the 7th.

The first real standout arrives Sunday the 6th afternoon, but it comes with a big caveat. The swell jumps to a solid 10ft from the ESE, sending combined energy right up to a powerful 1612. That is serious wave height. Short period swell of 10 seconds means it’ll be a bit raw and crumbly, and with heavy rain and a 15 mph cross-off, the lineup is going to be challenging. This one is strictly for advanced surfers only. Beginners need to stay well clear.

Monday the 7th remains chunky in the 6ft range out of the SE, and finally we get some proper offshore wind from the N. Period picks up to 10 seconds on the morning session, and you’ve got moderate energy pushing through (755). The afternoon holds similar size and turns clean with a moderate offshore breeze. This is your best paddle session of the short-term period – still a hefty wave, so take your wits.

Through Tuesday the 8th and Wednesday the 9th, the size backs off into the 4ft to 6ft range, with offshore winds still blowing on Wednesday morning. The energy drops to moderate (496), and the swell direction shifts a touch to the SSE. It’s surfable but nothing to write home about.

By Thursday the 10th and Friday the 11th, we fade into waist-high slop. Swells drop under 3ft with period shortening to 8 seconds. Energy numbers fall into the double digits (102 on Friday morning). Wind stays light offshore for a glassy look, but the waves will be small and weak.

From Saturday the 12th through the middle of the second week, it’s a pretty grim run. Heights bottom out at 1ft to 2ft, with periods occasionally spiking to 14 seconds on the 13th, but that long-period swell on a small tide just won’t wrap in right at Tainohama’s reef setup. You’re looking at almost a week of flat or near-flat conditions. There’s a brief pulse on Monday the 14th with 3ft from the ESE at 10 seconds and glassy conditions, but it’s marginal.

Then Tuesday the 15th throws up a last gasp: 5ft from the E at 8 seconds, though the wind turns onshore and the energy is mediocre (511). Not worth the drive.

Honestly, if you’re keen, target Monday the 7th afternoon for the best balance of size, offshore wind, and a clean face. The rest of the window is mostly small, weak, or just plain ordinary. If the waves stay this lackluster, you might be better off saving your energy for the next system.

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.
