The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for Narrabeen-Alley Rights.
We're looking at a solid run of surf kicking off this Saturday, August 1st, with some decent energy pushing through. The water temp is sitting at a pretty standard 64°F for this time of year, so nothing unusual there.
The first real swell shows up Saturday morning with a 5ft south-southeast swell, period around 9 seconds. The wind is light and cross-offshore from the west-southwest, which should keep things reasonably clean. Combined wave energy is moderate (450). Saturday afternoon gets even better with the wind swinging to a glassy east-northeast at just 3 mph, and the swell holding at 5ft. That's a beautiful window for some clean, lined-up waves. This is a standout session.
Sunday morning, August 2nd, is the absolute pick of the bunch. A 5ft south-southeast groundswell with a very long period of 13 seconds is pushing in, combined with a light north wind. The energy is pumping at 999 (moderate-to-strong). This long-period groundswell will wrap into the point beautifully, giving you some real grunt and shape. The paddle out will be easier between sets, and the waves will have plenty of push. The offshore wind from the north-west on Monday morning keeps a clean 3ft swell going, but the energy drops to 249.
After that, the consistency drops off sharply. From Tuesday the 4th right through to Thursday the 13th, it's mostly tiny, poor surf with swell heights under 2ft and very weak energy (mostly under 100). There are a few moments of surfable but ordinary conditions, like the 3ft swell on Saturday, August 8th, but that's got a short period of 8 seconds and cross-offshore wind, so it's not really worth getting excited about. The run of small, poor surf lasts about 10 days.
The next slight glimmer comes on Thursday, August 13th, with a 2ft east swell at 11 seconds and a little offshore wind from the west-northwest, but it's still very small with weak energy (94). The rest of the outlook through to mid-August remains tiny, with no real power to speak of.
For a spot like Narrabeen-Alley Rights, which is a very consistent beach-and-sandbar setup, it's a bit of a frustrating wait. But when it's on, it's on. The absolute standout is Sunday morning, August 2nd. That long-period, clean groundswell is the one to circle. Saturday afternoon is also a gem for glassy conditions. Don't bother with the rest unless you're a beginner looking for a tiny knee-high wave.
Rusty.
