The Lowdown

Alright, let's get into it. This is a look at what's gonna be running at Tainohama over the next couple of weeks, and honestly, it’s a story of a big, powerful start that fades out into much smaller options.

The opening act is a beauty, but it’s not the easiest to surf. On Wednesday August 5th, we’ve got a solid 15 ft groundswell hitting from the ESE. The combined energy is a hefty 9886, which is strong. That’s a lot of water moving around. This reef setup is exposed, so it’ll be handling that power. The wind is light from the ENE, keeping things cross and manageable. Water temps are sitting at 84°, which is a touch warmer than normal for this time of year. This is a powerful, heavy wave and really only for the advanced crew.

Thursday morning August 6th is the standout of the whole period. The swell is still a big 15 ft from the SE, and the wind swings around to a light cross-offshore from the NE. That’s a major positive, as it will groom the face. The period is 14 seconds, which is plenty of juice. It’s clean, powerful, and for advanced surfers only at this size. You’ve got to be on your game.

Friday August 7th gets messy as the wind picks up to a moderate breeze and turns onshore. The swell stays big around 16 ft, but it gets chopped out. That’s a pass for paddle surfing. The swell then starts to wind down through the weekend and into the next week, with onshore winds continuing to mess with the shape, making for poor conditions through to the 11th.

We hit a real lull mid-week. Wednesday August 12th morning is a weird one: the swell drops to about 6 ft from the S, but the wind goes glassy. It’s small, the combined energy is down to 975 (weak), but if you want a quiet, clean session on a small board, that’s about the best small-wave window on offer.

After that, the surf gets tiny and inconsistent. There’s a long gap of nothing special from the 14th to the 20th. We get a few glassy mornings on the 18th and 20th with tiny 5 ft and 3 ft swell, but it’s barely breaking with enough power to be fun. The short period on some of these days (like 6 seconds on the 17th) just won’t produce a decent wave.

All in all, the big, powerful, clean window on Thursday August 6th *morning* is the only true standout. The rest of the run is either too big and messy, or too small and gutless. If you’re a strong surfer, that Thursday is worth the trip.

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.
