The Lowdown
G'day, Rusty here.
Look, it's a bit of a mixed bag for Narrabeen-Alley Rights over the next couple of weeks. The water's sitting at 64°, which is pretty average for this time of year. We've got a couple of promising windows, but there's a fair bit of flatness and ordinary conditions to work through in between.
The standout is Sunday morning, the 2nd of August. We're looking at 5ft of SSE groundswell with a solid 13-second period, and the combined energy is moderate at 999. The wind is a light, cross-offshore breeze from the north, so the lineup will be clean. That's your best bet for a proper session.
Saturday afternoon, the 1st of August, is worth a look with 5ft SSE swell, but the 5 km/h east wind is cross-on, so expect a few ripples. Still, the energy is moderate at 413, and the swell is there.
Sunday afternoon, the 9th of August, shows some promise with 4ft of SE swell and a 10-second period, combined energy of 261. A light offshore from the NNW will keep it clean, and the swell direction is close to the optimum ENE. It's a decent option but a bit further out.
Monday morning, the 3rd of August, will have 3ft SE swell and a 11-second period, but the wind is a moderate 15 km/h offshore from the WNW, so it's rideable. The energy is low at 244, so it's not a standout.
The rest of the period is a write-off. There's a long stretch of tiny surf and poor conditions from Tuesday the 4th through to Saturday the 8th, and again from Monday the 10th onward, with only small, weak swells and cross-onshore winds. Honestly, if you're a paddle surfer, you'll be looking hard for a wave. That cross-offshore wind on the 10th and 13th with 4ft and 4ft of NE and E swell respectively might be more interesting for the kite crew.
So, keep your eyes on that Sunday morning, the 2nd. Everything else is a bit of a gamble or a long shot.
Rusty.
