The Lowdown
G’day, it’s Rusty. Lookin’ at Narrabeen-Alley Rights for the next couple of weeks, it’s a tough stretch. This is a beach and sandbar spot that’s exposed to swell, but the conditions are just not fallin’ into place for a proper paddle.
Right off the bat on Wednesday, September 2nd, we’ve got a tiny 1ft swell out of the ENE with a 10-second period. The wind is a cross-off at 15 km/h, so it’s clean, but the energy is weak (48). The water temp is 64°, pretty average for the season.
Thursday the 3rd sees the wind pick up to 25 km/h from the WNW, but the swell is still only 2ft with a real short 5-second period – no power there. Friday the 4th morning goes glassy with calm air, but the swell’s down to 1ft. The afternoon gets onshore and choppy.
This pattern of small surf and average winds hangs in until Tuesday the 8th. On the morning of the 8th, a pulse of 6ft swell shows up from the SSE with a short 8-second period and moderate wave energy (412). But the wind’s onshore at 15 km/h – messy.
On Wednesday the 9th afternoon, another pulse of 6ft SSE swell hits with 30 km/h cross-on winds. Fresh breeze, strong energy at 219, but it’s blown-out. This is a kite surfer’s day, not a paddle surfer’s.
The one real glimmer comes on Saturday the 12th. The morning has a 4ft swell from the SSE with an 11-second period – that’s a groundswell with some travelling power – and the energy is moderate-strong at 447. The wind is cross-off from the NNE at 15 km/h, so it’s clean. This is your standout of the fortnight. The break is *very consistent*, and on a day like this, you can expect crowds often. The swell direction (SSE) isn’t the absolute best for the spot (optimum is ENE), so the lines might not be perfect, but it’s your best bet.
Sunday the 13th morning is glassy with a 3ft NE swell but a weak period (6 seconds), so it’s just ordinary. The rest of the week into the 17th is a mix of tiny swells under 4ft with onshore or cross-shore winds. Tuesday the 15th morning has a clean 1ft cross-off, but it’s dead. Wednesday the 16th morning is clean with a 4ft SSE swell, but the period is short at 6 seconds.
If you want a wave, point the car at that Saturday morning, September 12th. The rest is a long gap of small, messy, or onshore rubbish. Forecasts can change, but right now it’s a lean run.
Rusty.
