The Lowdown

Alright, this is Rusty, and I’ve got a good look at what Tainohama has in store for us over the next couple of weeks. Let’s get into it.

First off, the water is sitting at a warm 82°, which is pretty much spot on for this time of year – nothing weird going on there, just your typical tropical bathwater.

We’ve got a slow start, no lie. Monday the 14th is a write-off with a weak, onshore 3ft from the southeast, just messy, so don’t bother. Tuesday the 15th is where it starts to perk up. Tuesday morning is glassy as hell with a 4ft SE swell, and that’s lookin’ real clean. Tuesday afternoon stays glassy with the same 4ft SE swell. This is your first real window.

Wednesday the 16th is small, but it’s offshore with a light N wind, so those 3ft to 3ft waves will be clean little peelers. Surfable, but nothing to write home about.

Thursday the 17th is a bit of a dud – small and cross-offshore, choppy enough to skip.

Now, hold onto your board for Friday the 18th. Morning brings a solid 7ft easterly swell, clean with 828 points of energy – that’s moderate but punchy. The afternoon stays 7ft but goes cross-shore, so still decent, just not perfect. This is a good day, but not the best.

Saturday the 19th is where it gets real. We’re talkin’ 10ft of groundswell from the ESE with a 14-second period. That’s *long* period energy – over 3400 points of energy, which is strong. It’s a reef break, so that long period will set up nicely, but it’s big, so this is for experienced surfers only. Cross-offshore wind keeps it clean. Sunday the 20th pumps even harder: 13ft of SE swell with 14 seconds and over 6600 points of energy. This is heavy, powerful, and clean. Beginners, stay on the beach.

Here’s the standout: Monday the 21st. Morning sees a massive 15ft SSE groundswell with a 15-second period – that’s very long period, over 9200 points of energy. Afternoon pushes it to 16ft with the same 15-second period, spiking to 9780 points. This is the best on offer. Proper, heavy, powerful swell with clean cross-offshore wind. This is a big-wave session for experts only. The reef will handle this beautifully, but you’ve got to know what you’re doing.

Tuesday the 22nd is a washout. We get an 18ft swell, but that’s paired with gale-force winds – 40 mph in the morning and 53 mph in the afternoon. That’s just dangerous. The afternoon goes offshore but it’s a severe gale. Don’t even think about paddling out.

After that, it drops off. Wednesday the 23rd is back to small, clean, offshore 3ft to 2ft – easy, but small. Thursday the 24th is flat and blown out. Friday the 25th has a glassy morning with 2ft from the SE, but it’s weak. Saturday the 26th is your last little glimmer – glassy conditions with a 3ft SSE swell, clean and fun for a longboard or fish.

Then from Sunday the 27th right through to the end of the forecast, it’s all cross-offshore wind and small, weak swell. A few days of 1ft to 3ft junk. Not worth paddling out.

So, overall: Tuesday the 15th for clean, fun small waves if you’re a beginner to intermediate, but the real gold is Monday the 21st – massive, clean, powerful groundswell for the experts. That’s your session. After that, it’s a long flat spell.

Stay salty,
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.
