The Lowdown
Alright, folks, Rusty here. Let’s have a look at what Tainohama has in store for us over the next couple of weeks.
The pattern starts off with some pretty ordinary conditions, but there is a glimmer of decent surf hidden in there if you’re patient. We’ve got a few windows where the swell picks up and the wind plays ball, but you’ll have to sit through a fair bit of average to get to them. There are also some sizeable gaps right at the end where it just goes flat.
Saturday the 5th is a write-off, to be honest. Tiny 3ft SSW swell with a light breeze and cloudy skies. Not worth paddling out for. Sunday the 6th sees the swell jump up to a solid 7ft to 8ft from the ESE, and the combined energy is strong at 829 to 1152. Problem is, it’s cross-offshore wind and we’ve got rain – heavy at times – so it’s a messy one. Not the day to charge it.
Now, Monday the 7th morning is where we get our first proper look. The swell is still a healthy 7ft from the SE with a period of 10 seconds, and crucially, we have a moderate offshore breeze from the North. That’s clean, that is. The water’s sitting at a warm 85°, which is a touch warmer than normal for this time of year. The combined energy is high at 924. This is the standout for the first week – Tainohama’s exposed reef setup will handle that SE swell nicely, and with the offshore wind, it’ll be proper. This is a good one for advanced surfers; it’s a little big for beginners at 7ft. Keep an eye on the tide.
Wednesday the 9th morning offers another chance with 7ft from the SSE and a moderate offshore breeze from the North, keeping things clean. The combined energy is still moderate to strong at 607. It’s a similar story to Monday, just slightly smaller. Not quite as good, but a solid backup. The afternoon freshens up a bit, making it a little more challenging.
After that, it drops off quickly. Thursday the 10th and Friday the 11th are poor – the wind goes onshore or cross-onshore and the swell loses all its energy. There’s a gap here of several days with nothing recommended. We see a little pulse on Saturday the 12th, but it’s small (3ft to 3ft) and weak. Sunday the 13th afternoon shows a bit of promise with 3ft S swell and a 10-second period, and the wind is light cross-offshore – that’s clean, but it’s small.
Tuesday the 15th morning is actually a bit of a surprise. We get a 3ft ESE swell, and the wind is glassy – dead calm. That’s about as clean as it gets, and the combined energy is moderate at 303. For a small day, that could be fun on the reef. It’s a light crowd spot sometimes, so you might have it to yourself. This is a nice little late-season treat.
From Wednesday the 16th onwards, it’s pretty much done. The swell drops right off to 1ft or less, and the energy is weak. There’s a long gap of flat conditions right through to the end of the 16-day window on the 20th. No surf on offer for that final stretch.
So, to sum it up: your best bet is Monday the 7th morning for the biggest, cleanest swell of the period, and keep Tuesday the 15th morning in mind for a glassy, small session if you’re after something clean and uncrowded. Everything else is a miss.
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.
