The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a bit of a flat spell on the horizon for this stretch. It’s going to be a slow grind, with the best surf just being a touch of small, workable swell. The water is sitting at a warm 80°, which is about average for this time of year, so nothing wild there.
The only break on the radar is Disappearing Sands. It’s an exposed, beginner-friendly spot, but it’s notoriously inconsistent, so you’ve got to pick your moments. The run starts on the morning of Tuesday, July 22nd. We’ll see a bit of a pulse push through with a 2ft SSW swell, but it’s a tricky one. The swell period is a very long 24 seconds, which is proper groundswell, but at a beach break like this, that long period can make things a bit straight and tricky. The wind is light and onshore, keeping it marginal. The combined energy is moderate (533).
The best window of the whole outlook looks to be Tuesday, July 28th, towards the afternoon. The swell drops to 3ft from the SSW, but the wind goes glassy. That’s the magic word. For a small, inconsistent break, having the surface glassy is a massive positive. It’ll be a high-tide, small-wave session for the longboard or a fun little fish. There’s some energy in the water (299), but it’s still weak. Expect crowds possible here as it’s the only show in town on a glassy day.
After that, it’s a long, slow fade. From Wednesday, July 30th, right through to the end of the run on Wednesday, August 5th, we’re looking at tiny, weak swell (under 2ft) with mostly cross-onshore winds. The combined energy drops into the double digits (below 100) and low triple digits, which is just weak. This is a big blank run for a spot that rarely breaks anyway. It’s not surprising for this area to have a quiet stretch like this.
Stay patient, keep an eye on the glassy windows, and don’t expect much.
Rusty.
