Tainohama Surf Forecast and Surf Report

Alright, Rusty here. Let’s break down what’s coming for Tainohama.

We start off slow. First thing Saturday morning, the 29th of August, there’s a small 2.6ft swell from the SSW with a 7-second period, and the wind is glassy. The water’s sitting at 84.4°, which is a touch warmer than normal for this time of year. But honestly, it’s just too ordinary to get excited. That afternoon, the wind goes cross-onshore and the energy drops, so it’s a write-off.

Sunday morning, the 30th, we see a little bump – 3.3ft from the SSW with an 8-second period, and the wind is glassy again. The combined energy is moderate (197). It’s surfable, but nothing special. The afternoon goes back to poor with light cross-onshore wind.

Monday the 31st and Tuesday the 1st of September are pretty flat and messy. The swell stays small, under 3.3ft, and the wind is either cross-onshore or onshore. The energy is weak (around 87 to 186). Not worth paddling out.

Wednesday the 2nd of September shows a bit more push – 4.6ft from the SSE with a 9-second period, but it’s still cross-onshore and choppy. The energy is getting up there (393), but the quality is poor, so it’s a pass.

Now, Thursday the 3rd of September is where things get interesting, but only for the experienced. We’ve got 8.2ft from the SSE with an 11-second period, which is a proper groundswell. The combined energy is strong (2611). That’s a big step up. However, it’s pretty big for beginners, and the wind is onshore, which will mess with the shape. The commentary says marginal tide conditions, so it’s not a clear winner.

Friday the 4th of September is a write-off. Strong cross-onshore wind, 8.2ft swell, but it’s choppy and poor. Forget it.

Here’s the first standout: Saturday morning, the 5th of September. Finally, we get some clean conditions. The swell is 3.0ft from the SSW, but with a 10-second period, and the wind is offshore from the north at 12 mph. The combined energy is moderate (301). This is a classic Tainohama morning – clean, moderate offshore, and the reef should be working. It’s a good option for the advanced surfer, and the crowds are only sometimes around, so you might get a few sets to yourself. The afternoon stays clean, too, with a cross-offshore wind and a slightly longer 11-second period.

Then we hit a bit of a rough patch. Sunday the 6th of September sees a big jump in size – 9.8ft to 11.5ft from the ESE, but it’s cross-onshore and choppy. The energy is strong (1485 to 2288), but the wind is ruining it. This is more of a kite-surfing setup than a paddle session.

Monday the 7th of September is a big one, but it’s for experts only. The morning shows 14.8ft from the ESE with an 11-second period, and the combined energy is massive (7153). The wind is onshore, though. The afternoon is even bigger – 18.0ft from the SE with a 12-second period, energy hitting 15812. The commentary says the swell is predicted to be too big for this break. It’s a monster, but unless you’re a very experienced charger, stay out of the water. The wind is cross-onshore and choppy.

The following days, from the 8th to the 12th of September, are a mix of big, messy swells and poor wind. There’s plenty of energy (3658 to 2578), but it’s all cross-onshore or onshore, and the waves are too big and unruly. The 10th of September shows a drop in size to 6.2ft from the SSE with a 10-second period, and the wind is cross-offshore, which is cleaner. The energy is moderate (666). It’s a decent option, but not the highlight.

Now, the real standout is Sunday morning, the 13th of September. This is the one to circle on the calendar. We’re looking at 14.8ft from the SE with a 13-second period – that’s a very long-period groundswell. The combined energy is massive (6012). The wind is glassy, dead calm. The commentary says “exceptional surf conditions for expert surfers.” This is a proper bomb. The long period will make the waves steep and powerful, and the reef at Tainohama will turn it into something special. It’s too big for beginners, but for the advanced crew, it’s a dream. The afternoon sees a drop to 13.1ft with a 12-second period, but the wind swings cross-onshore, so the morning is the window.

Overall, the first week is a mix of small, ordinary surf and big, messy conditions. The clear winners are Saturday the 5th of September for a clean, moderate session, and Sunday the 13th of September for a big, glassy, expert-level session. The
