Table - best surf conditions forecast for Narrabeen-Alley Rights over the next 16 days.
G’day, Rusty here. Gonna level with you – the next 16 days at Narrabeen-Alley Rights are mostly a struggle, but there are a couple of moments that’ll get your blood pumping.
Monday, 13th July kicks off with next to nothing – 0.2ft to 0.3ft of weak, short-period dribble. Tuesday through Thursday? Bone dry, zero swell. Proper flat spell.
Friday, 17th July, we see a pulse, but it’s ugly. Light rain and cross-onshore wind with 3ft to 4ft of 6-second ESE/SSE swell. Choppy and poor.
The golden window is Saturday, 18th July. Morning and afternoon go glassy – dead calm. You’ve got 4ft of east swell with a 8-second period, combined energy hitting 213 to 279 – moderate but lively for a beach setup. Water’s around 65°, right where it should be for this time of year. The swell direction is ENE, matching the spot’s sweet spot. It’ll be clean, fun, and rideable. Just know crowds are often a factor here, so set the alarm.
Sunday, 19th July, still 4ft but cross-onshore light breeze makes it marginal. Monday, 20th July morning, cleans up with a cross-off and 4ft of ENE swell – a solid second choice. Afternoon gets crossed up again.
Tuesday, 21st July morning, clean with 4ft of ENE swell, then it’s onshore and poor by afternoon.
From Wednesday, 22nd July, it’s a slow fade. Swell drops under 3ft, energy drains into double digits. Sure, there are a few clean mornings with offshore winds, but the waves are ordinary – 2ft to 3ft and unremarkable. The second week is quiet, with only a handful of surfable but weak days.
If you’re picking one, Saturday, 18th July is your day. Glassy, clean, and fun-sized. Don’t sleep on it.
Rusty.
