The Lowdown
Alright folks, Rusty here. Let’s have a look at the next couple of weeks for Narrabeen-Alley Rights. It’s a bit of a slow burner, but there’s a small window that’ll get the blood pumping.
We start off quiet. Friday the 17th offers a tiny 2ft easterly swell with a short 6-second period. The combined wave energy is weak (52). It’s glassy in the morning, making it surfable, but it’s pretty ordinary. Honestly, not worth rushing down for. The weekend is a write-off with onshore wind and messy conditions.
The real standout is Monday morning the 20th. The wind swings to a light westerly, going glassy. This cleans up a 6ft swell from the east-northeast with a 10-second period. The energy is moderate (571). This is the best on offer. For a surf break that’s very consistent, advanced, and exposed to the east-northeast – which is bang on the optimum direction – Monday morning is the session to circle. The water temp is 64°, which is about average for this time of year.
Tuesday morning the 21st is also worth a mention. Another glassy morning, with a clean 5ft east-northeast swell (440 energy). It’s a step down in size but still clean. The rest of the week is a mixed bag. Wednesday morning the 22nd has a clean 4ft swell from the east-northeast, but it’s smaller. Thursday morning the 23rd offers a 4ft southerly swell, but the period is short at 6 seconds.
After that, the surf drops right off. From the 24th through the end of the month, we’re looking at tiny waves, mostly under 2ft, and nothing worth paddling for. There’s a gap of almost a week with no real recommendations. That long-range swell on the 1st of August brings a 4ft southerly swell with short period (8 seconds), but the wind is going to be too strong for good quality.
So, to sum it up: don’t bother with the weekend. Set your alarm for Monday the 20th morning. That’s your best bet. Tuesday morning is the backup. The rest of the run is a dud.
Rusty.
