The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s coming up for Dee Why Point.
Right now, and for the next week or so, it’s pretty quiet. There’s a lot of small, weak energy and not much to get excited about. The water temp is sitting at 63°F, which is only a touch cooler than average for this time of year – nothing wild.
We’ve got a long gap of small, poor surf through until Sunday, August 23rd. That morning, the swell comes up a fraction to 3ft from the south, with a period of 10 seconds and clean, offshore winds from the WSW. The combined energy is still moderate (162), and it’s the first real sign of life, but it’s only just surfable – not a standout.
Monday the 24th and Tuesday the 25th are still small and ordinary, but Tuesday morning has a glassy moment with 2ft south swell – clean but tiny.
The real standout is building towards the end of the month. Sunday, August 30th is looking promising. The morning has 4ft from the ENE, period of 8 seconds, with clean cross-off winds from the NW. Combined energy is moderate (224). But the afternoon is the pick: 4ft from the ENE, still 8 seconds, with light cross-off winds from the west, and the energy jumps to 381 – that’s solid moderate energy. The guidance says Dee Why Point is a consistent point break that handles south-southeast swells best, and while the direction is a bit off, the clean conditions and building size make this the best window. Expect good surf.
From there, things keep improving. Tuesday, September 1st afternoon has 3ft from the ENE, period 9 seconds, with offshore winds from the WSW and energy at 271 – good surf. Wednesday, September 2nd morning is a gem: 4ft from the ENE, period of 11 seconds, light offshore winds from the west, and energy at 470 – strong wave energy. That’s groundswell, and for a point break like Dee Why, it should shape up nicely. Thursday, September 3rd morning is also solid with 5ft ENE swell, 11 seconds, clean cross-off from the NW, and energy at 450.
So, the best on offer is Sunday, August 30th afternoon through to Thursday, September 3rd morning. The standouts are definitely Wednesday the 2nd and Thursday the 3rd mornings – clean, moderate swell with good period and offshore winds. If you can get out then, it’ll be worth it. Crowds are possible at Dee Why Point, so keep that in mind.
Rusty.
