Alright, this is Rusty, and I'm lookin' straight at Tainohama for the next couple of weeks.

Right off the bat, we’ve got a beast of a SSW groundswell hitting Sunday morning, the 12th of July. We're talking a solid 10ft of swell with a long 16-second period, and the combined energy is massive at (4895). This is serious, heavy water – definitely for experienced surfers only. The water's sitting at 77°, which is a bit colder than normal for this time of year, so you might want an extra layer. But the kicker? Glassy conditions, dead calm wind. That's a recipe for some truly epic, clean lines at this reef setup, but only if you've got the skill. The swell direction is SSW, which isn't the perfect sweet spot for Tainohama as it prefers more S, but with this size and period, it'll still be pumping.

Sunday afternoon, the swell drops a touch to 8ft, still with a long 14-second period, and the energy is down to (2771), but still very strong. The wind stays glassy, so it'll be clean, but the risk of thunderstorms rolls in. Still excellent for the experienced crew.

Monday the 13th, the swell backs off to 5ft in the morning with a 12-second period and moderate energy (707). The wind is glass again, so you're looking at very good, clean surf, but it's a lot more manageable. By Monday afternoon, it's getting marginal as the wind swings onshore light.

Tuesday the 14th, the swell keeps dropping, down to 3ft, with energy falling to (247). Morning winds are a light cross-offshore from the NNE, so it’ll be clean but small. Afternoon turns glassy again, but it's only 3ft – a fun little session if you’re on a log.

The middle of the week, from Wednesday the 15th through to Friday the 17th, is pretty much a bust. Swell bottoms out below 2ft, energy drops into the double digits, and the wind is messy. Not worth paddling out.

Then we get a pulse of ESE swell starting Saturday the 18th. Saturday morning bumps up to 6ft with a longer 13-second period, energy at (939), but the wind is cross-onshore, making it choppy and marginal. Not the best.

Sunday the 19th of July is the other standout. We get a 8ft ESE swell in the morning, with a moderate 9-second period, and the energy is strong at (1595). But the wind goes glassy – dead calm! That’s a huge positive. The swell direction isn't ideal for this break's optimum, and short-period swell like this can be a bit fat on a reef, but with those clean conditions, it’ll be offering up some powerful, barreling sets for the experts.

From Monday the 20th onwards, the swell fades and the wind is mostly onshore or cross-onshore, keeping conditions ordinary. There are a few glassy windows in the second week, like Tuesday the 21st morning with a 3ft ESE swell, or Thursday the 23rd morning with a tiny 3ft ESE swell, but the energy is low. The 24th of July has strong offshore winds from the N, but the swell is only 2ft, so it’s all blow and no show.

The long-range stuff around the 26th and 27th has some very long-period swell (14-15 seconds) but the height is only 2ft. That's a tease – all that energy and no wave face.

So to wrap it up, your absolute best bet is the Sunday the 12th of July morning session. The size, the power, the long period, and the glassy wind will make Tainohama a heavy, world-class wave for those who can handle it. The Sunday the 19th morning is your second solid call if you missed the first, but it's a different kind of beast with that shorter-period ESE swell.

This is Rusty, signing off.

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.
