The Lowdown
Alright, surfers, Rusty here. Let’s look at what’s on the cards for Tainohama over the next couple of weeks. The water’s sitting at a toasty 83°, which is a touch warmer than normal for this time of year, so you might not even need a spring suit at first.
Right now, and for the next week, it’s pretty tame. We’ve got these long-period, 15 to 16-second groundswells rolling in from the southeast, but they’re tiny. We’re talking knee-high at best, around 1 feet. The combined energy is weak, sitting between 130 and 174 (weak). That’s not going to get anyone excited. The wind is kindest Saturday afternoon with that glassy NE breeze, and Monday morning looks clean too, but the waves are just too small to bother. It’s a waiting game.
We hit a real quiet patch from Thursday the 30th through to the 1st of August. The swell drops right off, the wind turns onshore or cross-on, and it’s mostly poor conditions. Sunday the 2nd sees a little bump in the swell, but the wind is onshore with storm clouds around, so it’s messy.
The real story starts Monday the 3rd of August. That’s when things wake up. A proper ESE groundswell kicks in, hitting 5 feet with a 17-second period. The combined energy jumps to 1319 (moderate). Monday morning looks excellent for experienced surfers; it’s clean with a light cross-offshore NNE breeze. It’s still a bit small for a full-on session unless you’re on a log, but the energy is there.
But the standout? Without a doubt, Wednesday the 5th of August. This is the one to point your calendar at. We’ve got a solid 13-foot groundswell from the ESE, with a 18-second period. The energy is very strong at 9792. And the best part? The wind is a clean cross-offshore breeze from the NNE and NE all day. This is for experts only — 13 feet is big territory. The wave quality will be unreal, but you better know what you’re doing. Thursday the 6th gets even bigger, hitting 16 feet, but that’s likely too much size for the break, even though the wind is perfect.
Friday the 7th is massive — 21 to 23 feet, with a fresh offshore N wind up to 19 mph. That’s a monster, and the forecast says it’s too big for Tainohama, so only the absolute elite should even look at it, and even then, it’s sketchy.
By Saturday the 8th, it gets blown out by a gale-force NNW wind, making it a write-off. Sunday the 9th looks cleaner again with a glassy morning and a dropping 5-foot swell, which could be fun.
So, for the best on offer: lock in Wednesday the 5th of August for the biggest, cleanest, most powerful surf for experts. If that’s too heavy, the morning of Monday the 3rd is a good warm-up for the more experienced crew.
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.
