The Lowdown

G'day, Rusty here, looking at your local stretch.

Alright, the next 16 days are a bit of a mixed bag with a few bright spots, but you’ll have to sit through some real flat spells. The water is sitting at 63°F, which is about average for this time of year, nothing too unusual.

The action starts on Sunday, August 23, but it’s a weak start. Narrabeen-Alley Rights (beach/sandbar) copped a small 2ft ENE swell with a 9 second period and a cross-shore NE breeze, so the surf is poor. The combined energy is a weak 56, so not much to get excited about.

Monday the 24th is a better bet, especially in the morning. That ENE swell bumps up to 3ft, and with a light NNE cross-off wind, the conditions will be clean. The period is short at 5 seconds, so it’ll be a bit crumbly, but it's surfable. The afternoon turns ugly with a strong NE wind.

Tuesday the 25th is the real standout for this run. The morning shows a 5ft NE swell with a 7 second period and a clean cross-off wind. The combined energy jumps to 302, which is moderate, and that’s a solid sign. The afternoon is even better—5ft, same NE direction, clean cross-off wind, and a stronger energy reading of 421. This is your best window. The swell is just over 5ft, so it’s getting a bit big for beginners, but it’s still manageable. The swell direction matches the optimum ENE direction pretty well, and the wind is light, so expect good surf. The only downside is that crowds are often here, so plan for company.

Wednesday the 26th falls apart. The swell drops and the wind swings onshore, making for poor conditions. Thursday the 27th has a glassy morning with a tiny 3ft swell, but it’s very ordinary. Friday the 28th is similar, with a glassy 3ft in the morning, but the afternoon brings a bigger 4ft SSE swell with a long 11 second period and a cross-on wind, so it’s messy.

Saturday the 29th is your next mention. The morning is glassy with a 3ft SSE swell at 9 seconds, and the energy is 245—moderate. The conditions are clean, making this a nice little session. The afternoon gets ruined by onshore winds.

From Sunday the 30th onward, the surf drops off significantly. The 31st and 1st of September have tiny, weak swells and glassy conditions, but it’s just not worth paddling out for. There’s a long gap of poor to non-existent surf from the 30th of August all the way through to the 7th of September. The 7th of September (Monday) afternoon shows a fresh 4ft NE swell with a 5 second period and a strong offshore wind, but the rating is poor, so don’t get your hopes up.

So, to boil it down: Tuesday the 25th is your best bet, with the afternoon session being the pick of the bunch. Saturday the 29th morning is a solid second option. The rest of the period is mostly flat or messy.

Rusty.

A general guide to surfing at Narrabeen-Alley Rights can be found by selecting the local surf guide option on the grey menu.
