Alright, Rusty here, let's talk about the waves at Tainohama.
The next week or so is a real mixed bag. We’ve got some solid, powerful swell rolling in towards the end of the week, but it’s going to come with some issues. It’s a proper groundswell with a long period, but the wind and tide are going to be fighting us for a few days. For most of the outlook, conditions are pretty ordinary.
Wednesday, the 9th of July, we start seeing some serious swell building – 8ft from the SSE, but with an onshore wind, the surf is just messy and not worth the paddle.
The real standout is going to be Friday the 11th of July into Saturday the 12th. Friday morning we’re looking at a solid 13ft of south swell, with a 17-second period. That’s a massive, powerful groundswell – combined wave energy is strong, sitting at 8460. The wind is light from the SSE, keeping things relatively clean for a reef break like this. Saturday morning holds similar, with 13ft from the S and a light breeze. This is big, powerful surf – over 8ft, so this is strictly for experienced surfers only at Tainohama. Crowds are possible here, so get out early.
Sunday the 13th sees the swell dropping back to a more manageable 8ft, but it’s still got plenty of energy (3254). There's a risk of thunderstorms in the afternoon though.
By Monday the 14th, the swell fades away. The energy drops right off (423) and we’re looking at small, 4ft waves. The wind goes glassy, which is beautiful, but the waves are just too small to get excited about.
From there, it’s a long stretch of tiny, weak surf and mostly poor conditions. There are a few days with glassy, clean conditions, but the swell is just too small to recommend. We’re looking at less than 3ft for days on end with very low combined energy. Tuesday the 22nd of July, we barely see a ripple – 1ft from the SSE with combined energy of only 88.
Water temperature is about average for this time of year. So, for the next 16 days, the only real window for action is Friday morning, the 11th, through Saturday. After that, expect a blank run with very little on offer.

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.
