The Lowdown
Alright, folks, Rusty here. Let's have a look at what's on the table for Tainohama over the next couple of weeks. We're working with a solid little reef setup that needs a good S swell and some decent wind to get it firing, but the truth is, it's gonna be a real quiet stretch.
The forecast has a gap right from the start. Tuesday the 14th of July is our first sniff of anything, but honestly, it’s not much to get excited about. The overall pattern is pretty flat and messy. We’ve got a run of days where the energy just isn’t there.
We kick off Tuesday morning with a small, clean 3ft swell from the SSW, period at 10 seconds, and a light cross-off breeze from the NNE. The combined energy is moderate at 241, but by the afternoon the wind goes glassy from the SSE, and the swell drops to 3ft. It's surfable but very ordinary. Wednesday the 15th continues that downward trend with 2ft to 3ft, still clean in the morning with a NE cross-off, but the wind shifts onshore by the afternoon, and conditions get poor.
Thursday the 16th of July might be the pick of the first week. The morning is glassy with an ENE breeze, swell is 3ft from the SSW, period at 8 seconds. It’s clean, but the energy is weak (100). It’s a fun little wave for a quiet session, but no standout. From Friday the 17th straight through to Monday the 28th of July, we’re stuck in a pattern of onshore winds, tiny swell, and poor conditions. The combined energy drops into the double digits, as low as 25 on Tuesday the 21st. There’s a lot of days with nothing to recommend—a big, flat gap.
Now, here’s where it gets a little interesting, but you have to be patient. A long-period swell tries to show up around Friday the 24th of July. We get a 1.0ft swell from the SE with an 18-second period. On its own, that’s barely a bump, but the energy is building. Saturday the 25th sees the same SE swell jump to 1ft, period at 16 seconds, and the combined energy climbs to 143 in the morning and 175 in the afternoon. But the wind is cross-onshore from the S, so the surface is choppy—still a poor conditions call.
The real flicker of hope comes on Sunday the 26th of July. The morning is glassy with an easterly breeze, 1ft swell from the SE, period at a clean 15 seconds. The energy is moderate at 165. It’s surfable but very ordinary. That long period will make it a bit walled-up at this reef, but for the few out, it could be clean and lined up. Then Monday the 27th of July morning, we get 2ft from the SSE, period 14 seconds, and the energy jumps to 301. The wind is light cross-onshore from the south, which isn't perfect, but it’s marginal. The south winds pick up in the afternoons and ruin it.
So, the truth is, there’s no true standout here. If you’re desperate, the glassy morning on Sunday the 26th offers the cleanest conditions with some long-period energy. Monday the 27th morning has the biggest energy reading, but the wind is a bit off. The water temperature is about average for this time of year, nothing wild. For a reef break that needs good S swell, we just aren't getting the size or the winds to align. It’s a lean couple of weeks, mates. Keep an eye on the long-range stuff, but for now, it’s more a time to wax the board and wait.
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.
