The Lowdown

Alright, Rusty here again, talkin’ Tainohama for the next couple weeks. It’s a slow start, so patience is key.

The first stretch, from Wednesday the 12th through to around the 20th, is flat and blown out. Tiny waves of 1 to 2 feet with crummy cross-onshore breezes and low wave energy – most of the time under 200. It’s a long dry spell. There’s a quick moment on Saturday morning the 15th with glassy conditions and a small 2 foot south-southwest swell, but it’s just barely rideable.

Now, the real action looks like it kicks off on Friday the 21st. That afternoon is the one to circle. We’ve got a 7 foot south-southwest swell, short period at 8 seconds, but the energy is pumping at 922 – a lot of push behind it. And with glassy wind? That’s the ticket. This is big, heavy, and a reef break like Tainohama at that size is for experts only. Water temp is a warm 84°, a touch above normal for the season.

Saturday the 22nd is still solid: a clean cross-offshore wind from the north-northeast, with 4 foot south swell in the morning, dropping a touch in the afternoon. Still clean, still fun, and will be less of a beast than Friday. The direction suits the break, and crowds could be expected.

After Sunday the 23rd, it drops back to small and onshore again, so don’t sleep on that Friday and Saturday window. It’s a way off, so keep checking in, but the potential is there.

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.
