The Lowdown
Alright, mate. Rusty here again, giving you the same story in feet and miles.
So, it's a slow burner. The first week or so is pretty flat, with waves barely a foot or so, and mostly crummy winds. You're looking at swell around 0.7ft to 1ft for days on end. The energy is weak. There are a few glassy sunrises on the 21st, 22nd, and 24th, but the swell's just not there. By the 24th we get a longer period, but still only 1ft. The 25th has a bit more push in the energy, but still only 1ft. Not worth getting your wetsuit wet for.
Now, mark your calendar for Monday, 27th July. The morning brings a clean 4ft swell from the SSE with a 12-second period and a light offshore cross-off wind from the NE. That's our golden moment, the first real decent wave. Water temp is pretty normal for this time of year.
Then the ocean loses its mind. Tuesday, 28th July, the swell doubles to 10ft from the S with a long, powerful 15-second period. The energy is massive. But the wind is onshore and choppy, making for a messy, dangerous day. This is 100% experts-only – 10ft is way too much for beginners. It stays big, between 7ft and 16ft for the rest of the window, but the winds are mostly from the wrong direction, ruining the shape. The Monday, 4th August morning looks a bit more manageable at 5ft from the ESE with a very long 18-second period, but the wind is still onshore, so it'll be lumpy.
The one to go for? Monday, 27th July morning at Tainohama (Japan) . That 4ft of clean groundswell, with a respectable 12-second period and a light offshore breeze, is your best chance at a real surf. The energy is solid. Just remember it's a reef break for advanced crew, and it can get a bit busy.
After that, it's a long slog of big, messy, onshore junk. From the 28th onwards, the conditions look a lot better for kite-surfing than for paddling – too much wind and lumpy water.
Stay safe, and I'll see you in the water.
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.
