Table - best surf conditions forecast for Tainohama over the next 16 days.
Alright, let’s talk about this in feet and miles, same story.
The surf over the next couple weeks is a real mixed bag. You get a solid window right away, then a long flat spell, and a promising pulse way down the line.
The best bet in the whole forecast is Monday the 27th. That’s a standout.
So, here we go. Monday morning the 13th at Tainohama is the go. It’s a reef break, advanced only. We’ve got a 5ft SSW groundswell pushing in with a period of 12 seconds, and the combined energy is sitting at 682 (moderate). The water is 77°, which is a bit colder than normal for this time of year – about two and a half degrees off, so that’s worth noting. The real kicker? The wind is dead calm, glassy. That’s going to make for some incredibly clean conditions. This is the pick of the early period.
The energy drops off quickly after that first pulse. Monday afternoon the wind turns onshore and quality dips. Tuesday the 14th still has clean windows – 3ft SSW and 3ft SSW with light offshore and glassy conditions, so those sessions will be fun for the experienced crew.
From Wednesday the 15th, the wheels fall off. Conditions go poor, and the swell drops to nothing. You’re looking at a gap of several days where there is nothing worth paddling out for. A tiny bump on the 19th with 3ft ESE, but the wind is junk. The energy stays low until the 22nd.
Wednesday the 22nd offers a bit of hope. We get a 3ft ESE groundswell with a period of 12 seconds, and the wind is clean and cross-offshore. The energy is 298 (moderate). It’s surfable and clean, but not a standout.
The main event, the one to really circle, is Monday the 27th. We get a much bigger pulse of S swell at 6ft, period 11 seconds, and the combined energy is a chunky 834 (strong). The wind is light and cross-offshore in the morning, clean. That’s the best, most powerful waves of the whole outlook. Tuesday the 28th still has size at 5ft, but the wind looks dodgy with onshore flow.

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.
