Table - best surf conditions forecast for Narrabeen-Alley Rights over the next 16 days.
Alright, Rusty here again, in feet and miles for you.
Let’s talk Narrabeen-Alley Rights. It’s gonna be quiet for a bit. For the next handful of days, there’s barely a ripple. The wind stays offshore or cross-offshore, keeping the water nice and clean, but the swell is so small it’s near flat from Sunday (12 July) all the way through to the middle of the week. Even when a pulse shows on Thursday and Friday, the wind swings onshore and turns it into a choppy mess. You’re looking at a pretty blank run until that following weekend.
The clear standout is Sunday the 19th. Here’s the deal: a glassy calm morning with no wind, and an 8ft swell rolling in from the east-northeast with a very long 11-second period. That’s a huge groundswell with a stacked energy reading of 1542. This is for experienced surfers only – it’s going to be well overhead. Water temperature is around 65°, average for the season. With this being a sandbar, that long-period wave can run a bit straight, but the conditions will be so glassy it’ll still be quality. Expect crowds, because this is a hotspot.
Monday the 20th morning is another good option, with a clean offshore northwest wind and a 7ft east-northeast swell, same 11-second period and still strong energy at 970. A solid session, but not quite the top shelf that Sunday morning is.
After that, the swell slowly drops off through the following days, with onshore winds returning and wave heights falling to under 3ft by the 23rd. The final days of the outlook are small again.
So circle Sunday the 19th – that’s your best chance for something special.
Rusty.
