The Lowdown

G'day, it's Rusty. Looks like we're in for a bit of a slow start here at Tainohama, but hold tight, because the second half of the outlook has some real promise. The first week or so is pretty grim, with a lot of onshore wind and messy conditions, but we'll see a proper shift in the pattern around the 7th of September.

The first few days are a write-off. From Monday the 31st of August right through to Wednesday the 3rd of September, we're dealing with small, weak swell and a persistent onshore wind. The wave energy is barely there, with values like 111 (moderate) for the combined energy, and the surf is just poor. It's one of those stretches where you're better off cleaning the wax off your board.

We get a little spike on Friday the 4th of September, with a 8ft SSW swell pushing in, but the wind is cross-shore and it's a messy, marginal setup. The combined energy jumps to 1721 (strong), but it's not clean enough to get excited about. The weekend of the 5th and 6th is a mixed bag – Saturday offers some small, clean waves with a light offshore wind, but the swell is tiny at 2ft to 3ft from the ESE. Sunday the 6th turns ugly with a strong cross-onshore wind and a big, crumbly 12ft ESE swell, definitely one for the kites, not the paddles.

Now, here's the good stuff. Monday the 7th of September is where things start to turn. We've got a 12ft ESE swell with a period of 10 seconds, and the wind goes cross-off in the afternoon. That's a solid groundswell and the combined energy is a massive 2822 (very strong). For the experienced crew, Monday afternoon is looking excellent, with clean conditions. Then Tuesday the 8th stays clean with a cross-off wind, but the swell drops to a more manageable 5ft from the SSE.

The real standout is Wednesday the 9th of September. Wednesday morning we have a 6ft SE swell, 11-second period, and a clean offshore wind from the north. The combined energy is 975 (strong), and the forecast is for "very good surf conditions". That's the session to circle on the calendar. The swell holds through to Thursday the 10th, with a bigger 8ft to 10ft SE swell, but the wind gets stronger, so Wednesday morning is the pick.

Friday the 11th is a write-off again with a howling cross-onshore near gale, and the swell is huge and messy. But we bounce back on Saturday the 12th of September, with a 6ft SE swell and clean cross-off winds – another excellent session for experienced surfers. The rest of the second week sees a mix of solid SSW groundswells, but the wind is often onshore, so it's a bit of a gamble. There's a big 16ft ESE swell on Tuesday the 15th of September, but it's cross-onshore.

So, to wrap it up: the first week is a dud. The best bet is definitely Wednesday morning, the 9th of September, at Tainohama. It's a reef break, so it handles the longer period swell well, and with that offshore wind, it's going to be clean and punchy. The water temperature is about average for this time of year, so a 3/2 wetsuit should be fine. It's an advanced spot, and it can get crowded sometimes, so get in early. The stand-out session is a solid 6ft SE groundswell with clean offshore winds.

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.
