The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for us.
Alright folks, strap in, because we’ve got a proper mixed bag coming over the next sixteen days. The first week or so is going to be pretty quiet on the wave front, with only tiny bumps showing, so don’t expect much action early on. The real interest kicks up around the start of August, with some serious size arriving, but it’ll come with tricky winds and some gnarly conditions.
Kicking things off, it’s a slow start. The first couple of days, the 21st and 22nd of July, we’re looking at absolute dribble. Waves are barely cracking 1 ft (0.3m), so your best bet is to leave the stick in the car and maybe enjoy a beach walk. That combined wave energy is reading in the low 30s (31) which is basically nothing. There’s a touch of glass out there on the Tuesday morning, but it’s just too small.
The 23rd is similar – still small, still weak. By the 24th, we get a little flicker of life. Friday morning, the swell bumps up to 1 ft (0.3m), but check out the period – 18 seconds! That’s a rare bit of ground long-period movement. The combined energy is only 74, though, so it’s weak, but glassy conditions could make for a real sneaky session if you’ve got a longboard and some patience. It was described as “surfable waves but very ordinary conditions.” The water is sitting about average for the time of year so nothing to worry about there.
Saturday the 25th sees a similar theme: 1.3 ft (0.4m) , 16-second swell, glassy again in the morning. This time the energy bumps to 139 (moderate energy) which is a bit more promising. It’s still small, but with that long period and an offshore breeze, it could be one of those early-morning surprises for the patient crew. By Sunday the 26th, the morning stays clean but still tiny, with 1.3 ft (0.4m) and a 15-second period. Afternoon looks a bit more interesting though with a shift to 2.6 ft (0.8m) S swell at 10 seconds – combined energy hits 272 (moderate). Things are heading in the right direction.
Now Monday the 27th is where we start to see the promise. Morning glass, 3 ft (0.9m) from the south with a period of 9 seconds. The combined energy reads 263 (moderate). This is the first day where I’d say it’s genuinely worth a paddle. Conditions are clean and glassy, so Tainohama could offer up some fun, small but clean lines. Not a standout yet, but the trend is our friend.
Then things go a bit wild. Tuesday the 28th brings a jump in size. The morning has 7.2 ft (2.2m) from the south with a 12-second period. That combined energy? A powerful 1400. That’s big wave energy, for sure. The problem is the wind kicks in from the SSW at 15 km/h, making it cross-onshore and choppy. This is advanced territory now – over 8 ft in the afternoon with 9.8 ft (3.0m) . That’s expert-only, and with the wind howling, it’s going to be tough. This is kite-surfing territory if you ask me.
Wednesday the 29th stays big and windy. 7.2 ft (2.2m) in the morning and 5.9 ft (1.8m) in the afternoon, both from the SSE, both onshore. The energy is still huge (1774 and 1197). With the onshore winds, paddle surfing looks like a battle. Not ideal, but if you’re an expert and you need to get wet, there’ll be power.
Thursday the 30th offers some relief. The swell drops to 4.3 ft (1.3m) from the SSW, period of 11 seconds, and the morning looks clean with a cross-off breeze from

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.
