Alright folks, Rusty here. Let’s talk about what’s coming up for Tainohama.
We’ve got a solid run of swell on the way, but it’s not all clean sailing. The water is sitting at 25°, which is a bit colder than usual for this time of year, so you might want a slightly thicker suit.
The first real call is Thursday morning, July 9th. We’re looking at a powerful 8ft swell out of the SSE, with a very long 15-second period. The combined energy is strong at 3506, so there’s plenty of grunt in the water. But the wind is onshore from the SSE, making it lumpy. It’s a reef break, so it’s for advanced crew only at this size.
Friday, July 10th, the swell builds to 12ft from the S with a 17-second period, and the energy jumps to 6993. Still onshore wind though, so it’s a bit of a battle. Honestly, with this much power and onshore wind, this setup might be more interesting for kite surfers than paddle surfers.
The standout of the whole forecast kicks off Saturday morning, July 11th. We’ve got a massive 13ft S swell, 17-second period, and the energy is roaring at 9878. It’s a solid, powerful groundswell. The wind is still onshore from the SSE, but the sheer size and consistency will have the experts frothing. This is a heavy, expert-only day. The crowd factor is listed as “sometimes” at Tainohama, so with this kind of swell, expect a few like-minded locals out there.
Sunday morning, July 12th, the swell drops to 10ft but the wind goes light and cross-onshore, which is a bit messy. However, Sunday afternoon looks magic: the swell is down to 8ft from the SSW, period a solid 14 seconds, and the wind goes glassy. The energy is still moderate at 2325. That’s the best window for a clean, powerful session without the massive, intimidating size.
Monday morning, July 13th, the swell is down to 5ft with glassy conditions from the NNE. The energy is low at 694, but it’ll be clean and user-friendly. Good for a cruise.
After that, the surf drops away significantly. From Tuesday, July 14th, through to Saturday, July 19th, it’s mostly small, weak, and onshore. There’s a long gap of poor to flat conditions. You’ll be waiting nearly a week for the next pulse.
That next pulse arrives on Sunday morning, July 19th, with a 6ft ESE swell, period 13 seconds, energy 1067, and light onshore wind. It’s marginal. Monday, July 20th, sees a bigger 8ft SE swell, period 14 seconds, energy 2214, but the wind is onshore again. The real standout in that second week is Tuesday morning, July 21st, with a 12ft SSE swell, period 13 seconds, and energy 3612. The wind is light and onshore again, but the power is there. Keep an eye on it.
Wednesday, July 22nd, morning looks clean with a 5ft SE swell and glassy wind from the E. Not huge, but fun. Then Friday morning, July 24th, brings another nice window: 6ft SSE swell, 12-second period, energy 1150, and glassy conditions from the ENE. That’s a great, clean option for the end of the run.
So, the best on offer is Saturday, July 11th for the big, heavy experts-only session, and Sunday afternoon, July 12th, for the clean, powerful, but not insane option. The second week has some promise, particularly Tuesday, July 21st and Friday, July 24th, but it’s less certain that far out.
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.
