The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking at Tainohama over the next couple of weeks.
Right now, we’ve got next to no surf on offer. The first few days are flat and not worth a paddle. Thursday the 30th and Friday the 31st of July are tiny. Saturday the 1st of August is the same story – small, weak waves with barely any energy (combined energy 41 to 58). Glassy conditions on Saturday afternoon will look pretty, but there’s nothing to ride.
We finally get something real on Sunday the 2nd of August. The morning brings 0.7m (2ft) of ESE swell with a very long 15-second period. Combined energy jumps into the moderate range (238). Winds are light cross-off from the north-northeast. Clean conditions. The afternoon is even better: 1.1m (4ft) from the ESE, 16-second period, combined energy 571. Light north winds, still cross-off. This is a proper groundswell, so expect longer waits between sets but more shape. Good for a reef like this.
Monday the 3rd of August morning is the real standout. Swell builds to 1.6m (5ft) from the ESE with a 16-second period and combined energy reaches a strong 1371. Light north-east cross-off breeze. Clean conditions. This is excellent surf for experienced surfers. It won’t be too big for the advanced crew, but beginners might get pushed around. By Monday afternoon, the wind swings onshore from the south at 12 mph, and the swell jumps to 2.1m (7ft). That onshore breeze will chop things up, and the energy spikes to 2597 – but conditions get messy.
Tuesday the 4th of August sees the swell hit 3.0m (10ft) in the morning from the ESE, period 17 seconds, combined energy 4901. That’s a lot of power. Cross-shore ENE breeze keeps it somewhat clean, but the size makes it expert-only. The afternoon is bigger, 3.5m (12ft), but onshore S wind 9 mph – not great.
Wednesday the 5th of August is massive. Morning swell is 5.5m (18ft) from the SE, 18-second period, combined energy 18780. Wind is light cross-off from the north-east, so it looks beautiful, but honestly, it’s too big for this break. Same goes for the afternoon: 6.5m (21ft), energy 24928, glassy cross-shore breeze, but just too much water moving.
Thursday the 6th of August stays huge: 7.5m (25ft) from the SSE, 18-second period, combined energy 38598. Some clouds, ENE wind at 9 mph, cross-shore. The sheer size makes this a kite-surfing show, not a paddle session. The afternoon is just as big but with a cross-onshore chop – still too big.
Friday the 7th of August – still large. 6.5m (21ft) from the SSE, 16-second period. Risk of thunderstorms, onshore wind. Not paddling material.
Saturday the 8th of August – the swell drops to 2.5m (8ft) from the SSW, period 15 seconds, combined energy 4763. Risk of thunderstorms and cross-onshore wind. It's smaller but messy. Not a great day for clean waves.
From Sunday the 9th of August through to Wednesday the 12th, we see a steady decline. Swells range from 0.8m (3ft) to 1.7m (6ft), mostly from the S or SSW, with onshore or cross-onshore winds. Combined energies drop under 1500. There’s a window on Wednesday the 12th morning: 0.8m (3ft) from the ESE, 8-second period, combined energy 205, light cross-off NE wind. Clean but small. Thursday the 13th and Friday the 14th offer similar knee-high possibilities.
So, the best of the lot is Sunday the 2nd of August afternoon through to Monday the 3rd of August morning. That’s your window. Clean, long-period groundswell, light offshore to cross-off winds, and solid size for a reef like Tainohama. Get on it early if you’ve got the skill.
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.
