The Lowdown
Alright, let’s get real about this stretch, because for a spot that usually pumps, it’s lookin’ pretty quiet for a while.
Narrabeen-Alley Rights is a very consistent, exposed beach and sandbar setup that normally handles a fair bit of ENE swell best. For the next couple of weeks, the wave energy is just not there. Water temp is sittin’ at 64°F, which is about average for the time of year here, so nothin’ wild.
We start off Sunday the 30th with a tiny 2ft SE swell, only a 9-second period, combined energy is a weak 92, and on top of that, we’ve got onshore wind. Poor surf. Monday the 31st is worse – down to 1ft. It stays like that for days. Tuesday through to the end of the first week, we’re lookin’ at nothing but 1ft to 1ft ENE or NE slop, with short periods. Wednesday the 2nd does have some clean, offshore NW wind in the morning, but the swell is just a whisper. The energy numbers are in the teens and twenties – that’s real weak.
Thursday the 3rd and Friday the 4th keep the trend going: tiny waves, nothing worth paddling for. Saturday the 5th kicks up a little – we get 3ft from the NE on the morning, but look at that period, only 5 seconds. That’s windswell, junky and inconsistent. The combined energy is only 39. Not even close to surfable. The afternoon sees a 25 mph W wind, so that’s a hard no.
Sunday the 6th is a write-off too. 4ft NE swell appears in the afternoon, but it’s a 4-second period and onshore wind. That’s a kite-surfing setup, not paddle surf. Combined energy hits 47, but it’s messy.
The second week doesn’t offer much redemption. Monday the 7th has some 2ft NE swell, but again, short period, cross-off wind – still poor conditions. Tuesday the 8th afternoon goes dead glassy, but wave height drops to a pathetic 0.7ft. Glassy on nothing is still nothing. The rest of the week stays small – 1ft to 3ft, mostly from the NE or ENE, periods in the 4-8 second range, with very ordinary conditions.
We get a little glimpse of hope on Monday the 14th of September. Mornin’ shows 3ft NE swell, 7-second period, combined energy at 84, with a light NE cross-off breeze keeping it clean. The score says surfable but very ordinary, and that’s the honest truth. Not a standout, but in this stretch it’s the best we get.
There’s a solid two-week gap startin’ from the 30th of August where there’s no real surf recommendation. This is a blank run. Narrabeen is normally very consistent, so this is a weird quiet patch. Forecasts can flip, but right now, if you’re not a kiter, you’re better off waitin’.
