Alright, let’s talk about Tainohama. The next couple weeks have a real pulse to them, starting with some solid, glassy days that are going to get the blood pumping, especially if you’re an experienced surfer. The water’s running a bit cooler than usual for July, about 76.6°, which is noticeable – you'll want the 4/3 or at least a good spring suit. The opening punch is a big, powerful groundswell, but it drops off pretty fast after the first few days, and the second week turns into a waiting game with smaller, less consistent energy. Let’s break it down.

The first standout kicks off on Saturday, July 11th. It’s not the cleanest with a cross-on breeze and some chop, but the swell is a solid 13.1ft from the SSW with a very long 17-second period. That’s a lot of energy in the water (8545). It’s an advanced-only affair – way too big for the average punter, but if you’ve got the skill and the nerve, the reef setup will be handling that power. It’s a big, raw day.

The true highlight window opens the next morning, Sunday, July 12th. The wind goes totally glassy, and you’ve got a 9.8ft SSW swell (4895 energy) still packing a 16-second period. This is where Tainohama really shows its face. The conditions are as clean as they get for the experienced crew. Crowds can be a factor here sometimes, but on a morning this good, it’s worth the company. The swell drops a little through the afternoon but stays clean and surfable.

By Monday, July 13th, the swell settles down to a very manageable 5.2ft with a 12-second period. The wind is glass again in the morning. This is fantastic, clean surf for the good intermediate surfer who wants something challenging but not terrifying. The afternoon stays glassy with a bit of a storm risk, but the waves are still fun at 4.9ft.

After that, the week fades. Tuesday the 14th has clean, cross-off winds but the swell is down to 3.3ft. By Wednesday the 15th, it’s getting small and weak, and from Thursday the 16th through to the end of the week, it’s mostly poor surf with onshore winds and barely any energy (down in the 50s and 70s). There’s a gap of poor to ordinary conditions for a few days.

We get a small reprieve on Saturday, July 18th, with a clean, 4.6ft swell from the ESE. It’s short-period (8 seconds) but the winds are good and cross-off, making it a fun little surf for a longboard or a fish. Nothing to write home about, but a nice break from the flatness.

Sunday, July 19th, brings a bigger bump to 8.2ft from the SE, but the wind is messy – cross-on and rainy. It’s a marginal day, and at that size with poor wind, it’s more of a challenge than a pleasure. The energy is moderate (1654), but the conditions just aren’t there. From there, the second week is a real grind. From July 20th to the 26th, it’s mostly onshore or cross-on winds with small, weak swell. The energy rarely cracks 400. There are a few moments of glass (like Wednesday the 22nd morning) or a clean cross-off (Sunday the 26th morning), but the swell is tiny – 2.6ft to 3.6ft at best. It’s a long stretch of small, ordinary surf that only the most dedicated would paddle out for.

So, to sum it up: the best on offer is hands-down Sunday, July 12th. Get in the water early for the glassy, 9.8ft SSW groundswell. The Monday morning is a solid second pick. After that, it’s a long, slow taper into flat, onshore slop for the second week. Keep an eye on that Sunday the 26th morning for a tiny, clean wave if you’re desperate, but the real glory days are all in the first weekend.

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.
