Tainohama Surf Forecast and Surf Report

G’day, Rusty here. Let’s look at what’s on the table for Tainohama over this sixteen-day stretch. It’s a fair wait for the good stuff, but there is a proper gem hiding in there—if you’re willing to sit through a flat spell and a bit of a choppy middle patch, a morning of pure glassy perfection is coming your way.

We’ve got a quiet start, with nothing worth paddling out for until Friday the 18th. The water’s sitting at a warm 83°, which is a touch warmer than normal for this time of year—a nice little bonus if you’re thin on rubber.

The real standout here is Friday morning, the 18th of September. That’s the session to circle on the calendar. The wind is dead glassy at 3 mph from the NE, and that swell is a solid 8ft from the east, with a period of 9 seconds. It’s not the longest period, but with combined swell energy of 1191, there’s some serious power in the water. This is quality for experienced surfers—the reef at Tainohama will be handling that east energy nicely, and with no wind to mess it up, you’ll be looking at clean, punchy walls. This isn’t a day for beginners, but if you know what you’re doing, get out there.

Right after that high point, the weekend gets a bit messy. Saturday the 19th has solid swell—8ft to 10ft from the ESE—and the period jumps to 13–14 seconds, which is that proper groundswell feel. Energy numbers are huge, hitting 3248 on Saturday afternoon. But the wind is cross-off from the north at 12 mph, so while it’s clean, those long-period sets can make the reef section tricky and the paddle-out a real expedition. Not quite the same magic as Friday morning.

Sunday the 20th sees a fresh offshore from the NNW at 19 mph, but the swell drops to 8ft. The conditions are clean, but with that strong wind, it’s more of a workable session than a classic one.

From Monday the 21st onward, the swell starts to fade. Monday morning still has a clean 5ft from the ESE at 12 seconds, with a moderate offshore—decent enough, but nothing to write home about. Then we hit a long, flat run. From Tuesday the 22nd through to Saturday the 26th, we’re looking at tiny waves, mostly under 1ft, and often with onshore or cross-onshore wind. There’s a small pulse on Saturday the 26th with 3ft from the SSE, but the onshore wind and rain showers kill it for surfing.

There’s a second pulse brewing towards the final days. Monday the 28th of September afternoon is worth watching. The wind goes dead glassy again, and the swell bumps up to 6ft from the south, with a 13-second period and energy at 1205. That’s another excellent window for experienced surfers—clean, powerful, and looking much like the Friday the 18th setup, just from the south. It could be a ripper, but it’s further out, so keep an eye on the forecasts.

Tuesday the 29th and Wednesday the 30th offer some clean morning windows with moderate onshore winds, but the swell is on the drop and the quality slides off. After that, we’re back to tiny leftovers into the first day of October.

So, for the whole run: if you only get one session, make it Friday morning the 18th of September. That glassy, 8ft east swell is about as good as it gets here. The backup would be Monday afternoon the 28th of September—another glassy window with south groundswell, but it’s a way off and less certain.

Stay frothy.

Rusty.
