The Lowdown
Alright, Rusty here. Let’s chew through the outlook for Dee Why Point.
The first week and a half is basically a dead loss for decent waves. Wednesday the 16th brings a big lump of 12ft S swell packing serious punch (energy at 2077), but that's way too much for this break. It’s an advanced-only wave already, and that size shuts it down for everyone. Water temp is about 64°F, which is normal for the season.
After that, it’s a grind. Thursday the 17th still has a 10ft swell but the wind is ugly and the forecast is shaky. Friday the 18th morning gives us a tiny window: 4ft S swell with glassy, dead-calm conditions. It’s clean and surfable, but nothing to write home about. The afternoon turns onshore and fades.
From Saturday the 19th all the way through the rest of September, it’s a painful, flat spell. Swell mostly under 3ft, periods are short or weird, and the wind is persistently cross or onshore. A couple of mornings turn glassy, like Saturday the 26th and Sunday the 27th, but the energy is weak – under 120 – and the waves are tiny. You’d be better off on a paddleboard.
Then, on Thursday the 1st of October, we finally get something to get excited about. The morning looks like the real deal: a 6ft S swell running on an 11-second period, energy at 900, and glassy conditions with a light offshore breeze. This is clean, powerful Dee Why Point at its best. It’s a long-range call, so keep your fingers crossed, but this one has serious potential. The afternoon will likely go onshore and messy.
So, the honest verdict: two weeks of nothing, then a proper morning session on the 1st of October. That’s your one to chase.
Rusty out.
