The Lowdown
Righto, let's have a look at what's on the table for Tainohama. This is a reef setup for advanced surfers only, so don't even think about bringing the foamboards. It's exposed to the south swell, and the optimum direction is from the south, so we want to see that on the charts.
The next couple of weeks start off, well, pretty ordinary. From Friday the 24th right through to the end of July, we’ve got tiny dribbles. Swell heights are just 1.0 ft to 2 ft coming in from the SE with a period around 10 seconds, and the combined energy is weak, sitting between 55 and 175 (weak to moderate). The winds are mostly light or glassy, which would normally be a dream, but there's just no power in the water. It’s surfable, but you’d be scratching for anything rideable. We go through a gap from the 29th to the 31st where things turn poor or marginal.
Then, we get a shift. On the morning of Sunday the 2nd of August, a new SSW swell shows up at 2 ft with a 14-second period, and the energy jumps to moderate at 255. With glassy conditions, this could offer a few fun ones. The next morning, Monday the 3rd of August, looks even better: 4 ft of SSW groundswell at 14 seconds, with the combined energy hitting 677 (moderate). The wind is glassy, so expect clean, lined-up waves. This is the first real standout of the period. It's still a manageable size for advanced guys, and that longer period will give the reef something to work with.
Now, for the real standout. The morning of Wednesday the 5th of August is where it’s at. We’ve got 8 ft of ESE swell with a period of 16 seconds – that’s a long-period groundswell. The combined energy is a hefty 2817 (strong). The wind is glassy, which is incredible. Get on it. At that size, it's edging towards big, but for an advanced crew on a reef, that's quality. The swell direction is almost from the optimum south-east, so Tainohama should really light up.
The 7th of August, Friday morning, is for the big dogs only. 13 ft of ESE swell at 18 seconds, with a combined energy of 10180 (very strong) and glassy wind. That is a serious, serious swell. This is not a day for the faint-hearted. It will be a raw, powerful, challenging wave, and only experts with the right board and a good head on their shoulders should even look at it.
The run finishes up with a drop on the Saturday morning of the 8th of August, going back to a more manageable 5 ft of E swell at 14 seconds with glassy conditions. A good day to recover from the previous one.
The water temperature is about average for the time of year, so no need to stress about a wetsuit thickness you don't have.
Honestly, there are two dates to circle: the morning of Monday the 3rd for a fun, clean, medium-sized south swell, and the absolute highlight being the morning of Wednesday the 5th of August for a bigger, glassy, long-period groundswell that will have the reef working perfectly.

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.
