The Lowdown
Alright, listen up. Rusty here. Let's talk about what's on offer at Tainohama over the next couple of weeks. This spot is a reef setup for the advanced crew, and it's fairly consistent, so there's hope.
Right now, we're looking at a gap of about a week before anything truly worth paddling out for. The first few days, from July 14th through the 20th, are mostly small, weak waves with a lot of onshore wind messing things up. The water is sitting at 77°F, which is a bit colder than normal for this time of year—about 2°F cooler than usual, so you might want that spring suit.
The standout session lands on Tuesday, July 28th. Tuesday morning is the pick of the bunch, with a clean 4ft swell coming from the SE. The period is a moderate 11 seconds, and we've got a nice NNE cross-off breeze to keep the faces smooth. The combined swell energy hits 367 (moderate wave energy), which means there's a bit of push behind it. On that same day, the afternoon looks good too, with the same 4ft SE swell and a light cross-off wind keeping things clean, though the period drops to 10 seconds. This reef break handles that SE swell direction well, and with manageable crowds, it's a solid window for the experienced surfer.
Wednesday, July 29th morning, is another decent call, with a 4ft SSE swell and cross-off NNE winds at 9 mph. The energy is still there at 278, and it'll be clean. The afternoon shifts to a cross-on breeze, so the morning is the time to go.
Beyond that, there's nothing else worth chasing. The last week of the month sees the swell fade back down into the 1.0ft to 1ft range, so unless you’re on a longboard in glassy conditions, it’s a write-off.
Keep an eye on that Tuesday the 28th. That’s the day.
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.
