Table - best surf conditions forecast for Tainohama over the next 16 days.
Alright folks, Rusty here. Let's talk about what's cooking at Tainohama for the next couple of weeks. We've got a real story brewing, with a slow start leading to a promising payoff, but you gotta be patient.
The immediate week ahead is pretty minimal. From now through the end of the week and into the next, the swell is small and mostly weak. The combined swell energy is low, hovering between 42 and 187, so don't expect much punch. The real standout window is a week and a half away, starting Sunday the 26th of July, and it looks like it could be worth the wait.
Monday morning on the 13th of July is the best session on offer for the whole first week. Tainohama will have a clean 5ft SSW swell at 12 seconds. That's a solid groundswell with moderate energy (682). The wind is glassy from the ENE at 3 mph, so it will be smooth. Just a heads-up, the water is sitting at 77°, which is 3° cooler than usual for this time of year, so it's a bit colder than normal. This is for advanced surfers only though; over 5ft at a reef break means it's not for beginners. That Monday afternoon drops off a bit to 5ft but stays glassy. After that, the surf fades fast.
Tuesday morning the 14th is smaller at 3ft from the SSW with a light cross-offshore NNE breeze at 6 mph, making it clean. But after that, for the next 10 days or so, it's mostly small, weak, and plagued by onshore or cross-onshore winds. The break is inconsistent, so a run of flat, poor quality days like this is fairly normal here. The combined energy drops to between 37 and 138, with periods mostly under 10 seconds. There's a brief, very ordinary moment on the morning of Thursday the 23rd with a flash of glassy conditions but only a 1ft SE swell.
Now for the good stuff. The standout starts Sunday the 26th of July. The morning brings a solid 4ft SE swell, period of 10 seconds, with a light cross-offshore breeze from the NE at 3 mph. This will be clean and it’s the first real hint of energy returning, with the combined swell reading 390. But the real gem is Monday the 27th of July. The morning has a clean 5ft SSE swell (11 seconds, 647 combined energy) with a light cross-offshore NE breeze. This is the absolute best of the forecast. It's still a bit big for beginners, but for advanced surfers, this is it. The afternoon stays clean and glassy with a 4ft SE swell (520 combined energy) and glassy S winds. That Monday is the one to circle on the calendar, but as it’s over a week out, treat it as a promising call rather than a dead certainty.
Don't sleep on Saturday the 25th either. It's not a classic, but the morning has a 1ft SE swell with a very long period of 16 seconds from a cross-offshore NNE wind. That long period means it will be super clean but might break a bit straight at this beach setup, so a point or reef break would be better. The wind builds to 12 mph in the afternoon though, so get out early.
By Tuesday the 28th, the swell drops back down to 3ft from the S with a cross breeze, so the window is closing. If you want the cleanest, best-shaped waves with some proper kick, you're waiting for the 27th of July. The rest of the week is a write off.
Stay patient, and keep your eyes on that Monday.
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.
