The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at what we’ve got coming up for the next couple of weeks at Tainohama. Gotta be straight with you – it’s a real slow start. We’re looking at a solid week of flat, weak, or just plain messy conditions before the ocean finally wakes up.
For the first week, from Monday the 27th of July through to the end of the month, it’s pretty grim. Monday morning gave us a tiny 1 ft push from the SE with a very long 14-second period, but the energy is weak, and it’s just ordinary. There’s a brief moment Monday afternoon with glassy conditions, but still, that 1 ft of swell is nothing to get excited about. The rest of the week is a write-off – onshore winds, tiny 1 ft to 2 ft waves, and poor conditions. You’re better off doing something else.
Heading into the first week of August, there’s still nothing doing. The 1st and 2nd of August are tiny and weak. On Sunday the 2nd, the wind goes cross-on and chops it up. Then on Monday the 3rd, the energy starts to show a pulse with a 4 ft swell from the ESE, but it’s blowing onshore and looks messy. Tuesday the 4th gets bigger, with a solid 8 ft on the morning and 8 ft on the afternoon, all from the ESE. This is a very long period groundswell (17-18 seconds), so the energy is serious, but the wind is onshore or cross-on. This is expert-only territory if you’re determined, and even then, the wind is going to make it a battle.
Now, here’s where it gets interesting. Wednesday the 5th of August into Thursday the 6th of August is the standout. On Wednesday morning, we’ve got a powerful 10 ft ESE swell with a cross-off wind from the NE. That’s clean, lined-up, and powerful. This is a reef setup, so that long-period groundswell is going to hold its shape really well. On Thursday, the wind goes properly offshore from the NNW, with a 9-12 mph breeze cleaning up another 10 ft of long-period ESE swell. This is the pick of the forecast. It’s big – over 8 ft – so this is strictly for experienced surfers. The water temperature is sitting at a warm 84°F, which is a touch warmer than normal for this time of year, so you won’t need a thick suit.
Friday the 7th of August still has good size, 7 ft from the E in the morning, cross-off wind, clean. But the swell drops off fast into the weekend, and by Saturday the 8th we’re back to tiny, onshore junk.
Looking into the second week, Monday the 10th of August shows a little pulse of 3 ft from the E with glassy conditions in the morning – that’s a fun little window for a longboard or a fish. Tuesday the 11th of August is similar, 3 ft with a light cross-off wind and clean. Nothing huge, but a welcome return to surfable waves.
So, the long and short of it: suffer through a flat first week, then brace for a big, expert-only pulse on the 5th and 6th of August. That’s the only true standout. After that, a few smaller clean days show up early in the second week.
Stay salty,
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.
