The Lowdown
G'day, Rusty here. Let’s have a look at what’s on the cards for Narrabeen-Alley Rights. It’s a beach/sandbar set-up that's very consistent, exposed to the ENE swell, and it's an advanced wave. The water temp is sitting at 64°, which is about normal for this time of year, so not much of a surprise there.
The first real chance to get wet comes Sunday, July 19th. It’s not a perfect picture, but we’ve got some swell building. Sunday morning sees a 7ft ENE swell with a period of 11 seconds. That’s a solid, long-period groundswell, and the combined energy is a hefty 1098 (moderate wave energy). The wind is onshore from the SE at 9 mph, though, so it’s going to be a bit messy. Sunday afternoon drops slightly to 7ft ENE swell, period 10 seconds, energy 814 (still moderate), but again with that onshore SE breeze at 6 mph. It’s marginal, but there’s something to work with if you’re keen.
Now, Monday, July 20th is the standout. Monday morning is the pick of the whole forecast. We’ve got a 6ft ENE swell, period 11 seconds, energy 792 (moderate). The wind is a glassy offshore from the W at 3 mph. That’s bloody clean. The conditions are expected to be very good. It’s a bit of a heavy wave for beginners at that size, but for the experienced crew, it’ll be firing. The crowd situation is listed as "often," so expect some company out there, but for a Monday morning, it might be a bit more relaxed. The swell direction (ENE) matches the optimum direction for the break, so it should be lining up nicely. Afternoon on Monday turns cross-shore from the NE at 9 mph, which will bring in some chop, so the morning is your window.
Tuesday, July 21st morning drops to 5ft ENE swell, period 10 seconds, energy 425. Wind is a clean cross-offshore from the N at 6 mph, so it’ll be rideable, but not as good as Monday. From Tuesday afternoon onwards, the swell steadily drops and the wind turns onshore or cross-shore, making conditions poor. There’s a long gap of poor surf from Wednesday, July 22nd right through to Thursday, July 30th. The swell dwindles to tiny 0.3ft to 1.0ft with periods of 8 to 9 seconds, and the energy drops to nil. It’s flat, basically.
Thursday, July 30th does see a bump in size, with a 5ft SSW swell on the morning, but it’s short-period (6 seconds) and onshore from the SSW at 9 mph, with rain showers. It’s a messy, choppy affair. The afternoon is worse. Friday, July 31st has a 6ft ESE swell in the morning, building to 7ft in the afternoon, but again, it’s short-period (6-7 seconds) and onshore, with rain. The combined energy is up to 416 (moderate) by the afternoon, but the wind is going to ruin it. For a beach/sandbar break, this set-up with strong wind and short-period swell looks more interesting for kite surfing than paddle surfing.
Saturday, August 1st is a write-off with strong NE winds at 22 mph and rain. There’s a slight improvement on Sunday, August 2nd, with a 4ft E swell, period 8 seconds, energy 202 (moderate). The wind is a clean cross-offshore from the N at 12 mph, so it’s surfable, but it’s a far cry from the Monday morning earlier.
The best on offer is without a doubt Monday, July 20th morning. That glassy 6ft ENE groundswell is the one to pencil in. The rest of the two weeks is mostly small, windy, or flat, so don’t get your hopes up for much else.
Rusty.
