The Lowdown

Alright, this is Rusty. Let’s break down what’s cookin’ at Tainohama.

The main event is the first day. Thursday morning, August 6th, is gonna be a ripper. We’re talkin’ a solid 4.5m swell from the SE, with a very long period of 14 seconds – that’s proper groundswell, and the energy is rippin’ at 8335 (moderate to strong). The wind is light and cross-offshore from the NE, so this reef break is gonna be glassy and clean. Water temp is 29°, which is a touch warmer than usual. This is a big swell, over 2.5m, so it’s strictly for the advanced crew. It’s a fairly consistent spot, but it can get crowded sometimes. The morning is your window.

That same afternoon, the swell hammers up to 5.5m, but the wind goes cross-on from the ESE. The energy jumps to 21621 (very strong), but it’ll be too big and choppy, even for experts.

Friday the 7th is a wash. Strong cross-onshore winds and stormy weather with a 4.0m swell, but it’s just messy. Saturday and Sunday morning the 9th look better, with the swell dropping to 1.5m on Sunday morning and glassy conditions from the SSE. That’s a nice window for experienced surfers, but the energy is way down at 1189 (weak to moderate).

From Monday the 10th onward, it’s a long, slow fade. The swell gets small and weak, mostly under 1.0m, with energy dropping to a few hundred. There are a few clean, glassy mornings, like Tuesday the 11th morning with a 1.3m swell, but it’s tiny. From the 13th on, it’s a long stretch of poor or marginal conditions, with only small, clean waves on the 19th and 20th mornings, but still under 1.2m. The 21st has a little 0.8m bump with clean cross-off winds, but it’s nothin’ special.

So, the bottom line: if you’re an expert, you gotta be at Tainohama on Thursday morning, August 6th. That’s the only real standout. Everything after that is a long, slow taper with a few small, clean moments for the longboard.

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.
