The Lowdown
G’day, Rusty here. Let’s break down what’s happening at Merewether - Ladies for the next sixteen days.
Honestly, it’s a slow start, and the first week doesn’t give us much to get excited about. Tuesday the 11th kicks off with a weak 2ft S swell, 8-second period, and only 71 units of energy – not worth suiting up. The best of the early run comes Wednesday morning the 12th: clean 4ft S groundswell with a 10-second period and 273 energy, pushed by a nice offshore WNW breeze at 12 mph. That’s the small window of decent surf, but even then it’s just average. The water’s 64°, a bit cooler than usual for this time of year.
Then it gets ugly. From Thursday the 13th right through to the middle of the third week, we’re looking at a long stretch of poor conditions – onshore winds, chop, and messy waves. There are a few bigger days, like Saturday the 15th afternoon with 6ft SSE swell, but that comes with strong cross-on winds and rough texture – honestly, that setup screams kiteboarding more than surfing. Sunday the 23rd brings a punchy 6ft ENE swell with 989 energy, but cross-shore winds keep it marginal, and the 10-second period means it’s not a clean groundswell.
If you’re patient, Friday the 21st morning offers a glassy moment: 3ft E swell, 9-second period, light wind – just about rideable but nothing special. Later on Monday the 25th afternoon, there’s a 6ft S swell with moderate energy (642), but the cross-on wind and 9-second period hold it back.
So, your only real standout is Wednesday morning the 12th. The rest is a long, barren run of poor quality. It’s one of those stretches where you’re better off waiting for the forecast to change.
Keep the faith,
Rusty
