The Lowdown
Alright folks, Rusty here. Let’s have a yarn about what’s coming up for our stretch of coast, focused on Dee Why Point.
Right now, it’s a bit of a slow burner. The first few days are looking pretty average with a lot of wind chop and messy conditions, so don’t expect much in the way of clean waves just yet. We’ve got a bit of a wait on our hands. The best bet in the whole outlook is a narrow window on the morning of Friday the 18th of September. That morning, the wind will be glassy – dead calm – and we’ll see a clean 5ft swell rolling in from the south with a 9-second period. The wave energy will be moderate (430). It’s a point break, so that short-period swell should wrap in nicely, and with no wind, it’ll be smooth as silk. That’s the standout for the whole period, but it’s a quick one.
Before that, the swell is pumping hard on Wednesday the 16th and Thursday the 17th, but the wind is a mess – strong cross-off or cross-on breezes making it ragged. The swell height on Wednesday morning is a solid 10ft from the south with a period of 10 seconds and very strong energy (1938), but with 19 mph cross-off winds, it’s going to be a battle. That kind of size is expert-only territory, and the quality is poor. Not worth the paddle.
After that Friday morning glass-off, it drops right back. The weekend of the 19th and 20th sees tiny 2ft to 3ft south swells, and the wind turns onshore again, so it’s pretty ordinary – surfable for a log if you’re desperate, but nothing to get excited about. The water temp is 64°F, which is about average for this time of year, so no surprises there.
The second week is a write-off, honestly. From the 21st right through to the 1st of October, it’s a long run of poor conditions. Swells get small or confused, and the wind is almost always from the east or northeast, putting a nasty cross-onshore chop on everything. The wave energy is weak to moderate for most of it. There’s a glimmer on the morning of the 30th of September with a clean 4ft swell from the north-east and a light cross-off breeze, but the period is only 6 seconds, so it’ll be weak and a bit crumbly. The rest of that week is a no-go.
So, to wrap it up: don’t bother until Friday morning the 18th of September. Set your alarm for that glassy session at Dee Why Point. After that, it’s a long, flat, choppy slog. But hey, forecasts change, and this coast can turn around quick.
Rusty.
