The Lowdown

Alright, Rusty here again, this time in feet and miles. Let's break down what's happening at Tainohama over the next couple of weeks.

The water is sitting at a balmy 84°, which is a touch warmer than normal for the season—you'll be comfortable in boardshorts. The first few days are a bit of a washout. Friday the 7th has a big, powerful swell from the SSE, with a ton of energy, but it's blown out by stormy onshore winds. Saturday the 8th is a little better, but still a bit messy.

The absolute standout is Sunday the 9th. The morning is gonna be epic. It's dead glassy with a light breeze from the ESE, and we've got a clean 3 feet of swell rolling in from the ESE with a long 13-second period. That's ideal for this reef break—long, well-shaped waves, and with no wind, it'll be a dream. The energy is solid, too.

Monday morning the 10th is another cracker. The wind is absolutely calm, glassy conditions, and we've got 4 feet of clean swell from the S. That's going to offer up some really fun, peeling lines, and it'll be easier to paddle out with the consistent sets. After that, the swell fades fast. We get a few clean mornings on Tuesday the 11th and Wednesday the 12th with light offshore winds, but the waves drop to around 3 feet. You can still have a fun session on a log or a fish, but the juice is gone.

From the 13th onward, it gets real slow. The swell energy plummets, and the wind is mostly onshore or poor. You'll see some glassy mornings on the 14th and 15th, but the waves are barely a foot or two. There's a long stretch here with nothing to get excited about. It's a pretty typical lull for this spot when the swell window closes. Your best bets are Sunday the 9th morning and Monday the 10th morning. Get out there.

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.
