The Lowdown
Alright folks, it's Rusty here, checkin' in with a long-range look at what's on the menu.
First up, we're gonna have a pretty flat spell for a while. There's surfable waves from Thursday morning the 24th of July, but the growth is real slow and the quality is very ordinary for the first week or so. The wait will be worth it for the patient ones among us, because a proper pulse is building for the second week.
The standout, without a doubt, will be Tainohama on Monday the 3rd of August. We’re looking at a solid ESE swell building to 5ft in the morning, jumping to 5ft by the afternoon with a very long 18-second period. The combined energy is massive at 1276, so there's serious power in the water. That afternoon session is calling with glassy conditions and a clean face. This is reef break territory, so only for the advanced crew – that size and period will be pushing through with real grunt, but it’s going to be epic. Tuesday the 4th keeps the fire burning with 5ft from the east at a 17-second interval (1386 energy) and clean, cross-off winds in the morning.
The water temperature is about average for the time of year at this stage.
For the week leading up to that, don't get your hopes up. The first real sign of life pops on Tuesday morning the 28th of July with a tiny 2ft south swell and glassy winds from the ENE, but it’s a short 8-second period which won't hold much form. We'll see a slow climb through the first of August, with Sunday the 2nd showing a bump to 2ft to 3ft from the ESE (409 energy) but described as marginal.
The crowd situation at Tainohama can get busy sometimes, so get your plan set early for that Monday and Tuesday window of the 3rd and 4th. For the beginners out there, the water gets too big after 5ft, so that 3rd of August is a "hold the camera" day, not a "paddle out" day for you.
So to sum it up: the next week is a scratch, with a few clean but tiny windows. The real gold is on the 3rd and 4th of August. Keep an eye on the sky, because that long period groundswell needs the right tide at a reef spot like Tainohama, but if it lines up, it'll be the best we've seen in a while.
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.
