The Lowdown
Alright, Rusty here, let's talk about what's on the cards for the next couple of weeks.
Look, I won't sugarcoat it – the start of this period is a total bust. The first few days are offering nothing but tiny, junky slop. We're looking at a pretty grim run from Monday the 14th all the way through to at least the end of that week. The swell energy is weak, mostly under 300 or so, with onshore and cross-onshore winds messing up whatever small bumps there are. There's really nothing to get excited about.
We start to see a slight flicker of life heading into the weekend of the 19th and 20th. The swell energy starts to climb into the 500s, but it's still small. Trestles (Lowers) will be the best of a bad bunch with some south-west swell in the 3 ft to 3 ft range. The early mornings might offer a brief window with light onshore breezes, but it's still only marginal. Crowds here are a given, so don't expect a quiet one.
The pattern continues into the following week with similar small swells. The best looking period on the charts actually falls on Sunday the 20th afternoon, where combined energy pushes up to 655 – that's moderate energy – with a 3 ft south-west swell. But it's still a marginal forecast.
From the 24th through the 29th, the energy drops right back down and the wind stays cross-on or onshore. The final day on the 29th of September shows a little pulse of energy (425) with 2 ft south-west swell and light onshore winds, but it's still a long way off and marginal at best.
So honestly, if you're desperate for a paddle, the mornings from the 19th to the 22nd are your best shot, but keep the expectations low. The water is currently much warmer than normal at 73°, which is pretty unusual for this time of year.
Rusty.
