The Lowdown
Alright, let’s talk about what’s coming up at Narrabeen-Alley Rights. This is a beach/sandbar setup that’s very consistent but often crowded – and it’s exposed to ENE swell. The water temperature is sitting around 64°F, which is pretty much average for this time of year, so nothing unusual there.
We’ve got a bit of a flat spell to start. From Tuesday July 14 right through to Saturday July 18, it’s pretty much a bust – poor conditions, no real surf on offer. You’ll be looking at small, choppy junk with onshore winds. Don’t bother paddling out.
Then Sunday July 19 morning shows a little pulse – 5 ft of ENE swell at 10 seconds, but it’s onshore and only marginal. That one’s a maybe, but not something to get excited about.
The first real standout hits Monday July 20 afternoon. The wind goes glassy – absolutely flat calm – and the swell is a clean 5 ft from the ENE, period 10 seconds. Combined energy is moderate (538). That’s going to be smooth, lined-up waves with no bump. If you can get there, that’s your session.
But the one I’d circle on the calendar is Thursday July 23 morning. Swell ticks up to 6 ft from the E, period 11 seconds, and the wind is cross-off from the WSW at 6 mph, keeping it clean. Combined energy is strong (817). That’s a solid groundswell with good shape, and the offshore component will hold the faces open. For a beach break, that’s about as good as it gets in this window. Just be ready for the crowd – it’s often busy there.
After that, things get messy again with rain and strong onshore winds through the 24th to 27th. Not worth it.
Then there’s a late bright spot on Tuesday July 28 morning: offshore NW wind at 12 mph, 4 ft E swell at 13 seconds, energy moderate (554). That’s clean and punchy, but a bit smaller. Still a fun session if you missed the earlier windows.
Wednesday July 29 morning also looks clean with offshore wind, but the swell drops to 3 ft – more of a longboard day.
So overall, the best on offer is Thursday July 23 morning. That’s the one with the most size, good period, and clean conditions. Monday July 20 afternoon is a close second for the glass. Everything else is either flat or blown out.
