Nanwan Beach (South Bay) Surf Forecast and Surf Report

G’day, I’m Rusty. Let’s get into what’s cookin’ for the next couple of weeks.

Honestly, it’s a pretty slow start. We’re lookin’ at a long, flat run for the first twelve days or so. There’s nothin’ really worth paddlin’ out for from now through to the 26th of September. The odd little bump shows up here and there, but it’s all tiny, weak, and the wind is mostly a cross-offshore breeze that ain’t doin’ us any favors. It’s pretty bleak – you’d be better off leavin’ the board in the car.

Then things finally switch on late on Saturday the 26th. It ain’t a world-beater, but we start to see some life. On Saturday afternoon, the wind goes glassy with a light breeze from the north at 3 mph, and we get a small 1 ft swell from the ESE with a very long period of 15 seconds. It’s clean and glassy, but the wave energy is still only moderate (121). It’s surfable, but nothin’ to write home about.

The real standout is Sunday the 27th of September. This is the one you wanna circle on the calendar. We’ve got a solid 7 ft to 7 ft swell from the east, with a very long 15-second period. The wind turns light offshore from the north and northwest at just 3 mph, makin’ for clean, lined-up waves. The combined swell energy jumps up to strong (1905 to 2263). This is proper groundswell. That long period will push the waves in with power, and at that size it’s gonna be for experienced surfers only. The break is Nanwan Beach (South Bay) – a beach and reef setup. With that long-period east swell, the reef will probably offer the best shape, but watch out for the beach breaks which might close out a bit. Crowds are often around here, but on a mornin’ like that, it’ll be worth sharin’ the lineup.

Then Monday the 28th of September mornin’ – another cracker. The swell builds to a solid 10 ft from the east, with a very long 16-second period. The combined energy hits very strong (3842). Winds are glassy from the northeast at 3 mph. That is some serious size and power. Again, strictly for experts – beginners, stay well away. The water temperature is 84°, about average for the time of year, so no surprises there. The afternoon of Monday the 28th drops off to flat, so make the most of that mornin’ session.

After that, Tuesday the 29th looks flat again with glassy conditions but no waves to speak of.

So, to sum it up: it’s a long, flat wait, but Sunday the 27th and Monday the 28th of September mornings are absolute standouts – clean, powerful, and serious east swell. Get in before the crowds, and if you ain’t experienced, sit this one out.

Rusty.
