The Lowdown

G’day, Rusty here. Look, I’m gonna level with you – the next two weeks at Narrabeen-Alley Rights are looking pretty grim for a proper paddle. There’s no real standout session on the cards, so we’re stuck with a long, flat run for the most part. The first week is a write-off with tiny waves and messy wind, and while the second week shows a bit more energy, the conditions just never line up for anything worth getting excited about.

Let’s start from Friday, 11th September. It’s dead flat, with a tiny 0.7ft swell from the ENE at a long period of 15 seconds, but the combined energy is weak (42). The water temp is 64°, which is pretty average for this time of year. The wind is cross-off in the morning, but it’s just too small to bother with.

Moving through Saturday the 12th and Sunday the 13th, the swell stays under 2ft, and things get messy. Saturday morning has a glassy surface but only 0.7ft on offer, so it’s a flat calm. Sunday afternoon sees a brief bump to 4ft from the NE, but it’s a 4-second wind swell with moderate cross-shore breeze, making for a lumpy, disappointing combo.

Monday the 14th is the best of a bad lot in the first week. The morning has 3ft from the NE with a light cross-off wind keeping it clean, but it’s still a short-period wind swell and the energy is low (60). It’s surfable but very ordinary – you’d be out there for the exercise, not the waves.

Then from Tuesday the 15th right through to Thursday the 24th, it’s a frustrating stretch. The swell barely gets above 3ft for days, and when it does – like on Thursday the 24th afternoon with 6ft from the NE – the combined energy jumps to moderate (234), but the wind is a moderate cross-shore from the NE, making it choppy and ugly. That’s 6ft of NE wind swell, but the conditions are just too scrappy to call it a goer.

Friday the 25th morning offers a glimmer: 3ft from the ENE with a light cross-off wind and clean conditions. The energy is still weak (96), and it’s described as surfable but very ordinary. It’s the closest thing to a session, but honestly, it’s not worth rushing for.

Through to Saturday the 26th afternoon, the swell holds around 4ft from the SSE, but the wind swings onshore or cross-shore, keeping things messy.

Bottom line: there are no good surf options in this 16-day window. The break is usually very consistent, so this long blank run is a bit of a surprise – it’s the kind of stretch that makes you check the forecast twice. For the more adventurous, the combination of small, punchy wind swell and persistent cross-shore winds could actually make this spot more interesting for kite surfing than paddle surfing for a few of those afternoons. But for a surfer wanting clean waves, sit this one out and wait for the next southerly change.

Rusty.
