The Lowdown
Alright folks, Rusty here. Let’s get into it for this stretch. We’re looking at a pretty quiet run overall, with a long gap of flat or very poor conditions to start. The first real surfable waves don't show up until the end of the run, so patience is key.
The first bit of hope comes on Sunday the 30th of August with a tiny pulse at Narrabeen-Alley Rights. It’s a beach/sandbar setup, exposed to the ENE. We’re talking a small 2ft swell from the SE, but with a short period of 10 seconds and only weak energy (123). The wind is glassy from the NW in the morning, so it’ll be clean, but the waves are pretty ordinary. The crowd factor is listed as "often", so expect company. The water temp is about average for the time of year. This is a beginner-friendly height, but the quality is low.
The outlook then goes completely flat. After that Sunday morning, we have a string of days with nothing worth paddling out for. From Sunday afternoon the 30th all the way through to Saturday the 13th of September, the guidance shows nothing but "poor surf conditions" with scores of zero. That’s a two-week gap with no genuine recommendations.
The only standout, and the one to circle on the calendar, is the final day of the forecast: Monday the 14th of September. Narrabeen-Alley Rights gets a little kick. The morning shows a 4ft swell from the NE, with a period of 7 seconds and moderate energy (128). The wind goes glassy from the NE, which is a major positive as it will result in clean, glassy waves. The swell is just over 3ft, but it’s not too big, so it’s still manageable for a range of surfers, though the short period means it’ll be a bit lumpy. The water is about average for the time of year. This is the only real hope in the whole 16-day window, and it’s a long way off, so keep an eye on it, but don’t hold your breath.
Rusty.
