The Lowdown
G’day, Rusty here, looking at the next sixteen days for Narrabeen-Alley Rights. We’ve got a bit of a slow start, but there’s a definite window of clean waves coming up, and then another pulse of energy later on that’s promising but a fair way off. Keep your eyes on Monday morning and that Monday a week later – those are the real standouts.
The first few days are a write-off. Friday the 17th and Saturday the 18th are small, weak, and messy with onshore winds – barely a ripple. The combined wave energy is only 52 to 152, so it’s basically flat. Sunday the 19th sees a jump in size with a 7ft swell from the ENE, but it’s a 11-second period and the wind is onshore, making it a marginal mess. The energy is up at 1123, but it’s not clean.
The real action kicks off on Monday the 20th. We’ve got a 6ft ENE groundswell with a 10-second period, and the wind goes glassy in the morning – absolute magic. The combined energy is a solid 628, and it’s going to be clean as a whistle. This is the pick of the first week. The water temp is about average for the time of year, nothing crazy. Tuesday the 21st holds that glassy theme in the morning with 5ft ENE swell, energy at 410, but the afternoon gets a cross-onshore breeze.
Wednesday the 22nd and Thursday the 23rd offer small, clean waves with offshore or cross-off winds, but the size drops to 4ft and then 3ft, so it’s fun but not pumping. By Friday the 24th and the weekend, it’s back to tiny and weak, with energy dropping to 31 and 7. That’s a solid gap of a few days with nothing worth chasing.
Now, look to Monday the 27th of July. We’ve got a 5ft SE groundswell with a very long 12-second period, and the wind is cross-offshore in the morning. The combined energy hits 741 – that’s proper power. This is a standout, but that long period can make it a bit straight at a beach break like this, so it might be better for the more experienced surfers. Still, the conditions will be clean. Tuesday the 28th is smaller but still clean in the morning with 4ft from the SE.
After that, the surf fades out again with onshore winds and weak energy through the end of the month. The last few days of July and into August are tiny and windy – not worth a second look.
So, the best on offer is Monday the 20th with that glassy ENE swell, and then Monday the 27th of July with the bigger, long-period SE groundswell and clean offshore winds. Crowds are often at Narrabeen-Alley Rights, so get in early for the cleanest ones.
Rusty.
