The Lowdown
Alright, grab your coffee, let's take a look at what's in store.
Well, I gotta be straight with you. The next week and a half is going to be a real struggle. We’re looking at a painful flat spell with next to nothing happening. From now until the 1st of August, it's all tiny ankle-snappers and slop. You’ll be seeing waves around 1ft to 2ft out of the southeast or east-southeast, with an average period that’s mostly short, around 10 seconds. The combined wave energy is weak, hovering between 41 and 172, just not enough to get excited about. There are some clean, glassy windows here and there – Thursday afternoon is looking dead flat but glassy, and Friday morning has a clean surface – but the swell just isn’t there to back it up. It’s the kind of stretch where you don't even bother loading the board on the car.
Then, hold on. It all changes. On Sunday, the 2nd of August, things start to wake up. That morning, we’ve got a pulse of 4ft from the east-southeast at 16 seconds rolling in with a combined energy of 689. The wind is glassy from the east-southeast, and it’s looking clean. This isn’t a beginner wave – that height and long period will have some push. This is where it gets interesting, but you’ll need to know your spot.
The real standout, and the one I’m pointing you to, is Monday morning, the 3rd of August. The swell builds to 6ft from the east-southeast at a very long 18 seconds. That’s serious groundswell (combined energy of 1892). For a reef setup like Tainohama, that’s the kind of energy that wraps in and unloads. Conditions are clean with a light cross-shore breeze. It will be big and powerful – advanced surfers only at this size. The following morning, Tuesday the 4th of August, glassy conditions with a 7ft easterly swell at 18 seconds looks incredible for experienced surfers, but the afternoon gets choppy and blown out.
So, to sum it up: you wait nearly ten days for the first real pulse. The best windows are the morning of Monday the 3rd and Tuesday the 4th of August. It’s not a beginner's swell; it’s a reef-break groundswell for the crew that knows how to handle it. Don't expect any crowds on the flats, but when that swell hits, be ready.

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.
