Updates in hr min s Forecast update imminent
Alright, mate, Rusty here. Let’s get straight into it. The start is a bit of a washout for the wave hunters. We’ve got a big pulse of southerly swell mid-week, but it’s too damn meaty for most, and the open beaches will be feeling the brunt of it.
The real standout in this whole window is Wednesday the 8th of July. Narrabeen-South (Sydney) is the only spot on the radar, and it’s the call for experienced surfers only. Early on Wednesday morning we’ve got a solid 8ft southerly groundswell, period pushing 11 seconds, and a clean southwest offshore breeze. The combined swell energy is a hefty 2438 (strong) – there’s plenty of grunt in the water. The water temp sits at 65°F, pretty much average for this time of year. This is the pick of the bunch, but it’s not a beginners' wave – over 8ft demands respect.
Rewind to the Sunday and Monday before that – 5th and 6th July – we’ve got similar size (10ft–12ft) but it’s too big for the break, so don’t even bother unless you’re a masochist. Big southerly swell, moderate to fresh cross-off winds, but the file says it’s too big for this break.
Thursday the 9th sees the swell drop to a more manageable 7ft from the southeast, with a 10-second period. Early morning has a gentle cross-off breeze, combined energy at 907 (moderate). Expect very good surf, but still a bit chunky for the average punter.
Friday the 10th offers a further drop to 6ft from the SE, 9-second period, light cross-off winds on Friday morning, swinging offshore in the afternoon with a light breeze from the southwest. Combined energy around 603–648 (moderate). Clean conditions, good for those who can handle a bit of power.
From Saturday the 11th onward, the swell drops off a cliff. We’re looking at waist-high slop through to Monday the 20th – a solid gap of over a week with poor conditions and combined energy dropping into the double digits. A few ordinary waves pop up around the 17th and 18th, but nothing you’d paddle for. The swell just dies. That’s the deal.
So, in short: Wednesday morning the 8th is your one genuine standout. Get out there if you’ve got the chops. Everything else is either too big or totally flat. Keep an eye on the long-range updates, but for now, that’s the story.
Rusty.
