The Lowdown

Alright folks, Rusty here. Let’s see what’s cooking for Tainohama over the next couple of weeks.

Right now, it’s a slow start. The first few days are pretty flat. Friday the 31st of July we’ve got tiny 1ft waves from the SE with a 13-second period, which is a decent long-period groundswell, but there’s just no push behind it. The water’s sitting at 84°, a touch warmer than usual for this time of year. The glassy conditions are a nice sight, but it’s barely surfable.

Saturday the 1st and Sunday the 2nd of August stay small, with a bit more size showing Sunday afternoon – 4ft from the ESE with a 16-second period and clean cross-off winds. The energy’s building, but it’s still not doing much. We’re waiting for the real show.

The standout window. Monday the 3rd of August morning is where things start to get interesting. We’ve got 5ft from the ESE, 16-second period, clean cross-off breeze. The combined energy is already in the strong range (1262). This is a solid, well-shaped groundswell for experienced surfers. By Tuesday the 4th of August morning, it’s game on. Glassy conditions, 10ft from the ESE, 18-second period – that’s a very long period groundswell. The energy is very strong (6239). This is a serious, clean, powerful swell. Tainohama is a reef break, so that long period will wrap in nicely. This is the absolute best on offer. For beginners, 10ft is too big, but for the experienced crew, this is exceptional.

Wednesday the 5th of August morning sees the swell peak at a massive 16ft from the SE, 17-second period, with light cross winds. The energy is through the roof (13683). Later that day and into Thursday, it’s predicted to be too big for the break, even for experts. The wind stays clean for the most part, but the swell is just colossal. This is a window for the brave and the very skilled, or honestly, it might be more interesting for kite surfers than paddle surfing, given the size and the reef setup.

After that, the swell drops quickly. Friday the 7th of August through the weekend sees a mix of stormy conditions, risk of thunderstorms, and dropping 8ft to 16ft swells with onshore and cross-onshore winds. The quality drops off hard.

The second week, from the 9th of August onward, we’re back to smaller, more manageable waves. Sunday the 9th afternoon looks fun with a glassy 4ft from the SSW, 13-second period. Then Monday the 10th through Tuesday the 11th offers consistent 4ft to 4ft ESE swells with clean winds and glassy conditions. The energy is moderate (between 600 and 906). It’s not the epic swell of the first week, but it’s clean, fun, and much more user-friendly. Crowds are listed as “sometimes” at Tainohama, so keep that in mind.

After the 12th, the size drops to under 3ft for a few days, with a short period on the 15th of August (7 seconds) that won’t offer much shape.

So, the bottom line: the absolute best is Tuesday the 4th of August morning – glassy, 10ft, long-period SE groundswell. The second best is Monday the 3rd of August morning. The second week has clean, smaller waves but nothing that will blow your mind. The big stuff in the first week is for experts only or maybe the kite crew.

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.
