The Lowdown
Alright folks, Rusty here, letting you know what’s on the cards for our stretch of coast over the next couple of weeks. Look, I’ll be straight with you – this is a tough run. We’re looking at a long stretch of pretty ordinary surf with only one session that really gets the heart pumping. You’re gonna need patience.
Right now, we’ve got a bit of a wait ahead. The first tiny pulse of waves shows up on Monday the 3rd of August, but it’s nothing to write home about. We’ve got a small 3ft swell from the southeast rolling in with a weak moderate combined swell energy (194). The wind is light and cross-off, so it’s clean, but the whole setup is pretty average. The water temp is sitting at 64°, which is pretty much dead-on normal for this time of year.
The rest of the first week and all of the second week are a write-off. We’re talking day after day of poor surf conditions, with heights barely nudging 1ft to 2ft. It’s a bleak stretch.
Now, Wednesday the 12th of August (morning) finally offers a glimmer of hope. It’s the only real standout in the whole outlook. Narrabeen-Alley Rights is a beach/sandbar setup that’s very consistent and exposed to the swell, and we’ll see a 3ft swell from the ENE. The combined swell energy is moderate (175), and with a light, clean cross-off wind from the north, the surface will be tidy. It’s still a small day, and definitely not one for the beginners – it’s an advanced break – but for those who know the bank, this is the best we’re getting. The period is 10 seconds, a decent groundswell that should offer some shape. Keep in mind, this break can draw a crowd, so expect company out there.
After that little spike, it’s back to the doldrums. The swell drops off, and we’re into tiny leftovers with messy or onshore winds for the rest of the forecast window. It’s a long blank run, but for this area, that’s not unusual. Stick with it, things will change.
Rusty.
