The Lowdown
G’day, Rusty here, lookin’ at what’s on offer for Narrabeen-Alley Rights over the next sixteen days.
From now through Sunday the 14th, there is nothin’ doin’. Little waves and messy winds keep it flat and ordinary. The first worthwhile paddle is Monday the 14th morning – swell 3 ft from the NE, short period of 6 seconds, but a clean cross-off breeze from the north. Energy is weak at 153. Water temp’s 64°, about normal for the season.
Through the week it stays average. Tuesday the 16th afternoon pushes 6 ft from the SSE, energy at 481, but the wind is cross-onshore and messy – better for kite-surfing.
The absolute standout is Saturday the 19th morning. A 3 ft east swell, 11-second period – proper groundswell – energy at 242. And the wind is glassy, clean. For this beach/sandbar, that east direction and glass will set it right up. Not big, but really fun. Crowds are often here, but dawn patrol will be worth it.
After that, Sunday the 20th morning has glass again but only 1 ft. Not much.
Finally, Sunday the 27th morning – a week out – shows a 4 ft NE groundswell, 8-second period, energy at 206, with a clean cross-off. Promising but far off.
So, Saturday the 19th morning is your best bet. Everything else is small, blown out, or average.
Rusty.
