The Lowdown
Alright, Rusty here. Let's take a look at what's on the table for the next couple of weeks.
Right off the bat, don't get your hopes up too high—this is a pretty lean run for the most part. We’ve got a little window of half-decent surf on Monday the 3rd of August, but after that, it’s a long, flat spell. From Tuesday the 4th of August right through to Saturday the 15th of August, there’s basically nothing worth paddling out for. That’s nearly two weeks of tiny, weak waves or flatness. The energy just drops off a cliff, with readings like 54 and even down to 14 for the combined energy of all swells directed here. It’s a real desert.
The best bet, and the only real standout, is Monday morning the 3rd of August at Narrabeen-Alley Rights. It’s a beach/sandbar setup, so it can be a bit of a gamble, but this morning has some promise. We’ve got a 3 ft swell from the SE, with a period of 11 seconds—that’s a decent groundswell, giving some shape and energy. The wind is a light cross-off from the north at 6 mph, so it’ll be clean. The combined energy is 236 (moderate), so there’s enough push. Water temp is sitting at 63°, which is about 1° cooler than average for this time of year, so nothing unusual there. Crowds are often an issue here, so expect some company if you’re chasing that window.
Monday afternoon drops off a bit in size to 3 ft, and the wind swings to a stronger cross-off from the WSW at 9 mph, but it’s still surfable, just not as good.
After that, it’s a long wait. It’s not until Sunday the 16th of August that we see a pulse of energy come back. That morning, the swell picks up to 4 ft from the SSE, with a 9-second period, and the combined energy jumps to 261 (moderate). The wind is light cross-off from the WSW at 9 mph, making for clean conditions. That’s a solid option, but it’s a long way off, so keep an eye on it. The following Monday morning the 17th also shows a 5 ft swell from the SE, with a 10-second period, and a very strong energy reading of 460, but the wind is light cross-on, which might mess with the shape a bit. Still, for a beach break, that’s a lot of energy, and it could be a bit of a handful for the average punter.
So, bottom line: Monday morning the 3rd is your best early call, then wait it out for the 16th or 17th. A few decent windows, but a lot of flat in between.
