The Lowdown
Alright, Rusty here. Let’s break down Dee Why Point.
We’re starting off in a flat spell. The next couple of days have almost nothing – waves around 2 to 3 feet from the south, but the wind is trash. It’s cross-on or cross, choppy, and just ugly. Water temp is about 63°, which is a touch cooler than normal for this time of year.
Then on Wednesday the 16th, the ocean wakes up. A solid south swell hits, pushing 10 feet in the morning and nearly 12 feet by the afternoon. That’s a ton of energy – we’re talking 1439 and 2702 on the energy scale. This is expert-only. Anything over 8 feet gets real heavy, and over 10 feet is for the brave. The wind is clean and cross-off, but the size will sort out the crowd quickly.
Thursday the 17th keeps the size up, with 10 feet from the south in the morning and 8 feet in the afternoon. The wind is clean and cross-off again in the morning. The energy is massive – 3360 in the morning session. The period is around 10 seconds, so it’s got punch, but it’s not the real long-period groundswell that races through.
After that, it drops off. Friday the 18th has 5-foot waves, but the wind is light and the period is short. Then we hit a long lull. From Saturday the 19th all the way to Saturday the 26th, the surf is tiny – mostly under 3 feet, with weak winds and poor energy. A few mornings have offshore wind, like the 19th with 1-foot waves and a 17-second period, but there’s just not enough swell to make it worthwhile.
The standout is Wednesday the 16th and Thursday the 17th. If you are an experienced surfer and you want clean, powerful south swell, Wednesday afternoon is the pick. The wind is clean, the swell is maxing out. Just be smart about it. For the rest of the run, it’s a waiting game. That blank stretch from the 19th to the 26th is a long one, but that’s the way the ocean rolls.
Rusty.
