The Lowdown

Alright folks, Rusty here. Let's chew the fat on Tainohama for the next couple of weeks.

Straight up, it’s a bit of a mixed bag. We’ve got a good pulse of long-period swell coming, but the wind is going to be the main story for the first week, and it ain't always playing nice. The water is a balmy 84°, which is a touch warmer than usual for this time of year – you’ll feel that straight off.

The real standout of the whole forecast is the morning of Wednesday, 2nd September. We get a solid 6ft of groundswell from the SSW, with a long 14-second period packing a ton of energy. The wind is a light cross-offshore breeze from the NNE, keeping the faces clean. This is an advanced wave at a reef break, and with that size and power, it’s strictly for the experienced crew. The sets will have some real grunt, but the longer period will mean proper lulls between them. This is the session to circle.

Before that, we’ve got some mushy stuff to work through. The swell pulses up to 10ft on Tuesday, 25th August, but the wind is stubbornly cross-onshore, making it a messy, choppy affair. That size is going to be a handful, and with the poor wind, it’s not worth the paddle. Through the end of August, the swell drops right off, with waves below 3ft and mostly onshore or cross-onshore winds. There’s a brief moment on the morning of Friday, 28th August, with glassy conditions on 3ft SSE swell, but the period is a short 8 seconds, so it’ll be weak and crumbly.

After that first week, the energy fades significantly. The end of August and start of September sees the swell dropping to knee-high mush. The winds improve, turning from the north with clean conditions from Wednesday, 2nd September onwards, but the swell just isn't there to back it up. The 6ft spike on the 2nd is your one and only proper window.

For those looking for a longboard cruise in the small stuff, the morning of Saturday, 6th September has a glassy 2ft SE groundswell with an 11-second period, giving a little bit of push for the tiny waves. But honestly, for anyone chasing a real wave, the pick of the entire 16 days is that Wednesday morning.

Rusty out.

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.
