Imperial Version
Alright crew, Rusty here. Let’s talk Tainohama. The next couple of weeks have some ups and downs, but the real prize is right at the start.
Monday the 13th is your golden ticket. A proper 5ft SSW groundswell with a 12-second period is pumping, carrying 707 units of energy. The wind is dead calm – glassy perfection. This is a heavy reef break for advanced surfers, so don’t go in without experience, but the waves will be clean and lined up.
Tuesday the 14th drops to 3ft to 3ft, but the wind stays friendly – cross-offshore in the morning and glassy again by afternoon. The energy is in the 200s, but it’ll be clean and fun.
Wednesday the 15th the swell drops to about 2ft, and the wind turns onshore, so we’re looking at poor surf. It stays small and ugly through Thursday and Friday morning – nothing worth paddling out for.
Friday afternoon the 17th throws a curveball with a 3ft ESE swell, but the period jumps to 16 seconds. That’s a super long-period groundswell, which can be weird on a reef – might not break well. Plus the wind is onshore, so it’s a gamble.
Saturday the 18th has some size at 4ft from the ESE with a 12-second period, but the wind is onshore and choppy. Leave it.
Sunday the 19th is more of the same – messy onshore wind.
Monday the 21st brings a 5ft to 5ft ESE swell, but the wind is cross-onshore, so the surface will be chopped up. Not ideal.
Then the second week offers a couple of windows. Tuesday the 22nd morning shows 4ft ESE swell with glassy conditions – that’s a clean session. Wednesday the 23rd morning is similar with 3ft and glass. These are your best bets for clean waves after the first few days, but they’re over a week out, so keep an eye on it.
From Thursday the 24th through Tuesday the 28th, the swell drops below 3ft, energy is low, and the wind is mostly onshore. There’s a tiny 1ft SE swell on the 25th with a 16-second period, but it’s too small to get excited about.
Bottom line: Monday the 13th is the day to be in the water. Everything else is a waiting game.
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.
