The Lowdown

G’day, I’m Rusty. Let’s have a look at what’s on offer at Narrabeen-Alley Rights over the next couple of weeks.

Right off the bat, we’ve got a real mixed bag here. The first few days are pretty grim – tiny waves and ordinary conditions. The standouts are going to be way down the line, so you’ll need a bit of patience. The best surf on offer is pointing toward Tuesday, September 15th and Friday, September 18th, when we finally see some proper swell and clean winds line up.

Alright, let’s walk through it. Saturday September 5th starts with a weak 1 ft of ENE swell, period 9 seconds, and a cross-off breeze. The wave energy is weak (19), and it’s just poor surf – not worth a paddle. The afternoon sees a slight bump to 3 ft from the NE, but that’s a short period windswell (5 seconds) and the wind is offshore, so it’s clean but ordinary. Still, the combined energy is only 58 – weak.

Sunday September 6th is a write-off – tiny 2 ft and 1 ft, with messy cross-onshore winds. Monday September 7th morning has glassy conditions but only 0.7 ft of E swell – flat as a tack. The afternoon brings 4 ft from the SSE, but it’s cross-on and choppy, with moderate energy (192).

Tuesday September 8th morning has the biggest swell of the early period – 8 ft from the SSE, period 9 seconds, and strong energy (872). That’s a solid size, but it’s cross-on wind and the conditions are “fairly choppy.” This one’s for experts only, and even then, the wind is a letdown. The afternoon drops right off.

Wednesday September 9th is a bit of a tease – 5 ft SSE swell with a light cross-shore breeze and moderate energy (325), but it’s still called “marginal.” The afternoon gets ugly with a strong 28 mph southerly and messy conditions.

Then we hit a long, flat spell. From Thursday September 10th right through to Monday September 14th, it’s tiny – mostly 0.7 ft or less, with combined energy often below 20. Some glassy mornings, but nothing to ride. That’s a solid 5-day gap of no real surf.

The real standout comes on Tuesday, September 15th. The morning shows 3 ft of SSE swell, period 10 seconds, with a light NNW offshore breeze and clean conditions. The combined energy is 259 – moderate and solid. The wind is offshore, the waves are clean, and the direction is a good match for the break. This is the best session of the whole forecast. It’s not huge, but it’s clean and fun.

Wednesday September 16th and Thursday September 17th are back to poor, choppy conditions with small SSE swell.

Friday, September 18th morning is another strong option. We’ve got 3 ft of SSE swell, period 11 seconds, with a light NNE cross-off breeze and clean conditions. The energy is 348 – moderate, pushing into solid territory. This is a longer-period groundswell, so it’ll hold up well here. The afternoon stays clean but the winds pick up a bit, so the morning is the pick.

Saturday September 19th is a letdown – 2 ft SSE with light offshore winds, clean but small. Sunday September 20th is mostly tiny and not worth it.

So, overall, the first week is a struggle. The two clear standouts are the morning of Tuesday, September 15th and the morning of Friday, September 18th. Both have clean, offshore or cross-off winds, moderate swell energy, and good wave height. The 18th has a longer period (11 seconds), which should give better shape. These are the only sessions that really earn a paddle.

Crowds at Narrabeen-Alley Rights are often around, so expect company on those standout days.

There’s no water temperature data provided, so I can’t comment on that.

Rusty.
