The Lowdown
Alright folks, Rusty here, and we’ve got a solid window of surf coming up at Dee Why Point. The overall pattern is a fun run of SSE groundswell to kick things off, with some proper glassy conditions making the early sessions the real standouts. There’s a bit of a lull after the weekend, but the second week has a promising pulse of S swell that’s worth watching for the brave.
The first real action hits this Friday morning, September 11th. We’re looking at a clean 5ft SSE swell with a 10-second period, swinging out of the SW with a light breeze (10 km/h) making for clean faces. The combined energy is solid (509), so there’s some push in the water. This is your best bet for the opening days – consistent, well-shaped for the point, and the offshore wind will keep it tidy. It’s an advanced wave, so you’ll want your wits about you, and it can get busy here, so expect company.
Saturday morning, September 12th is the true gem. The swell drops a touch to 4ft from the SSE (11-second period), but the wind is dead glassy from the S at only 5 km/h. That is a magic combo for Dee Why Point. Clean lines, a bit of long-period energy, and the energy levels are still moderate (462). This is the session to aim for if you want silky walls.
Things go a bit ordinary from Saturday afternoon through to Tuesday as the swell fades and winds turn onshore or cross-shore. The surf gets small and weak, with combined energy dropping below 200. There’s a gap of a few days with nothing worth paddling out for.
Then we get a spike in the forecast for Wednesday morning, September 16th. An 8ft S swell (9-second period) rolls in with a clean cross-off breeze (25 km/h from the S). The energy spikes hard to 1207 – that’s proper power and a lot of water moving. This is expert territory; it will be big, raw, and a bit unruly. Only for the experienced crew. It’s a solid option if you’ve got the nerve and the right board.
The week after that has a few OK windows. Sunday morning, September 20th sees a clean 4ft S swell with a cross-off NW breeze making for clean conditions (323 energy). Not a standout, but a decent enough option for a Sunday session. It’s not the size or quality of the opening weekend.
Wednesday morning, September 23rd has a 4ft NE swell with a solid offshore from the W at 15 km/h – clean again, and the energy is there (228). Worth a look if the earlier bigger days are already done.
Overall, the best of the week is Friday and Saturday morning. After that, the Wednesday big swell is the wildcard for experts. Keep an eye on the early sessions – that’s where the magic is.
