The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Tainohama over the next couple of weeks.
Straight up, it’s a rough start. The first week and a bit is a write-off. From Friday the 17th to Sunday the 26th of July, the surf is just plain poor. We’re looking at tiny, weak waves – mostly around 1ft to 1ft – with onshore winds messing things up. The swell energy is feeble, barely cracking 50 (48 is the highest we see in that stretch). It’s not worth paddling out for. You’d be better off checking the wind forecast for something else.
There’s a long, flat gap here, about a week and a half with nothing to recommend.
The only real glimmer in the whole outlook comes on Sunday the 26th of July. The morning shows a bit of life with a 4ft SSE swell rolling in. The period is 14 seconds, so it’s got some proper groundswell grunt to it – that’s good for shape and power, though it might make the sets a bit spaced out. The wind is light and onshore from the SSE, but at 6 mph it’s not too rough. The combined energy jumps to 439 (moderate). It’s a marginal call, but it’s the best we’ve got. Tainohama is a reef break, so that longer period swell should wrap in nicely. The water temp is sitting at 81°, which is about average for the time of year.
After that, the swell really cranks up. Monday the 27th of July sees a big jump: 12ft to 13ft SSE swell with a 14-second period. That’s serious power – the energy readings hit 6440 and 6702 (very strong). But the wind is onshore, and for a reef break, that’s going to be a washing machine. This is expert-only territory, and even then it’s going to be a battle. The wind stays onshore or cross-onshore through the rest of the week, with the swell hanging around 13ft to 15ft. By Wednesday the 29th, winds are up to 19 mph, making it a mess. Honestly, for a beach-and-reef setup like this, those conditions look more interesting for kite surfing than paddle surfing.
The last day worth mentioning is Friday the 31st of July. The swell drops to 8ft from the SSW, but the period is short – only 8 seconds. The wind is cross-onshore at 12 mph, so it’s going to be choppy and weak. Not a standout.
So, the only real chance to get a wave in is Sunday the 26th of July in the morning. It’s not perfect, but it’s the only thing on the menu. After that, the big swell comes but with bad wind, so it’s a pass for most.
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.
