The Lowdown
G'day, it's Rusty. Let's look at what's on offer at Tainohama. The next couple of weeks start with some juice but sketchy conditions, then it cleans up nicely before fading into small, glassy mornings.
Water temp is 84°F, a touch warmer than average for this time of year.
Monday afternoon (August 3rd) is a bust – storm risk, 6 ft ESE swell with onshore south wind at 15 mph. Combined energy is 1512, but it's messy.
Tuesday the 4th brings size. Morning sees 10 ft from the ESE with a 16 second period, energy at 7025. Wind is on from the south but lighter at 10 mph. Afternoon the swell pushes to 12 ft with a 17 second period, energy hitting 12950. It's big, but the onshore wind kills it for surfing.
The standout is Wednesday the 5th. Morning is all class – 15 ft ESE swell at 16 seconds, energy at 10911, and the wind swings cross-offshore from the northeast at 10 mph. Clean. This is exceptional, expert-only stuff. The afternoon is slightly smaller at 16 ft from the SE with a very long 17 second period, cross-shore and light. Still quality.
Thursday the 6th is pumping but too big. 18 ft from the SE – huge. Morning winds are clean cross-off, but combined energy is 15820 and it's genuinely too big for this break. Friday the 7th is the same story – 18 ft SSE swell, heavy energy, cross to cross-on winds. This whole stretch is more interesting for kite surfing than paddle surfing.
The swell drops over the weekend. Saturday the 8th morning has 13 ft from the south, 15 seconds, energy 9450, with a cross-shore wind. Still big but cleaner. The afternoon gets messy with rain. Sunday the 9th is a washout with onshore wind.
Monday the 10th and Tuesday the 11th are poor – dropping swell, onshore wind, rain. Not worth it.
Then we get glassy windows. Wednesday the 12th morning is a beauty: wind goes glassy – dead calm – and the swell is a clean 5 ft from the SSW at 12 seconds. Energy is only 793, but it's clean. Crowds are possible. It's small but tidy.
From Thursday the 13th through the end on Tuesday the 18th, it's mostly small and weak – under 5 ft with short periods. There are more glassy windows on Friday the 14th morning and Saturday the 15th, but swell is under 3 ft. Sunday the 16th morning has a little bump of 5 ft from the ESE at 12 seconds with clean cross-off winds, but that's it.
The real winner is Wednesday morning, August 5th. That's the one. Otherwise, the glassy Wednesday morning on the 12th offers a smaller, clean session.
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.
