The Lowdown
G’day, Rusty here. Let’s be straight – we’re looking at Tainohama, a reef break for the advanced crew, and the coming days are mostly a write-off. There’s a big gap of poor conditions to wade through before we finally get something worth the paddle.
The water’s sitting about average for this time of year, nothing wild there.
Right now, Saturday the 29th is a no-go. Cloudy morning with a weak 3 ft SSW swell (moderate energy at 129) and a cross-onshore breeze; afternoon gets worse with a risk of thunderstorms and 4 ft SSW swell (151 energy) but still messy. Sunday the 30th brings a rare glimmer – a glassy morning with 3 ft SSW swell (178 energy) and clean conditions. Score it a 1 out of 10, so just surfable but ordinary. The afternoon turns again with a cross-onshore and 2 ft S swell (88 energy). Then Monday 31st through to Friday 4th September is a brutal run. Swell builds, but winds stay onshore or cross-onshore, and the quality is shot. Monday has 2 ft S swell (100–130 energy), Tuesday 4 ft S swell (285–299 energy), Wednesday blows up with a solid 7 ft SSE swell (2068 energy – that’s strong, way too big for beginners) but rain showers and onshore winds ruin it. Thursday keeps 5–6 ft S swell (604–767 energy) and fresh onshore winds. Friday the 4th is a mess: 5 ft S swell (970 energy) with a strong cross-onshore. Kite surfers might eye this stretch, but for a paddle? Forget it.
Now, Saturday 5th September – this is the standout. The morning brings a 5 ft SE swell (530 energy) with glassy conditions. Expect very good surf, clean, and the optimum direction from the S matches nicely. It’s a true bright spot. The afternoon stays glassy with 3 ft S swell (364 energy) but good surf too. Sunday 6th and Monday 7th September drop back into poor form with cross-onshore winds and 5 ft SE swell (320–357 energy). Tuesday 8th September afternoon offers a reprieve: a clean 3 ft SSE swell (213 energy) with a light cross-offshore breeze, giving good surf. Wednesday 9th is a write-off again with onshore gales. But Thursday 10th and Friday 11th September are the real gems. Thursday morning: 4 ft ESE swell (555 energy), offshore N wind, clean – very good surf. Thursday afternoon: glassy, 4 ft ESE swell (513 energy), very good. Friday: 5 ft ESE swell (649–687 energy), long period of 12–13 seconds (proper groundswell), cross-offshore winds, clean. That’s top-tier for an advanced reef. Saturday 12th September holds with 3 ft E swell (312 energy), offshore, clean, good. Sunday 13th fades to 2 ft E swell (123 energy), still clean but ordinary.
Bottom line: the best on offer are Saturday 5th September with that glassy SE swell, and the stretch from Thursday 10th to Friday 11th September with the clean, long-period ESE groundswell. Those are the only two standouts in a pretty bleak 16-day window.
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.
