The Lowdown

Alright folks, Rusty here. Let’s get stuck into what’s on offer for the coming weeks.

It’s been a quiet start for us, with a solid gap of no surf to speak of. The first proper chance we see doesn't really come until the afternoon of Friday the 7th, and even then it’s tiny. The first couple of days are basically a write-off.

Friday 7th August – The afternoon is where we finally get a look. It’s small, with a clean 1ft swell from the SSW. The period is a very long 19 seconds, which is proper groundswell energy – that’s great for a point break like this one. The wind is light and cross-offshore, making for clean faces. The combined energy is moderate at 200, but the size is tiny. It’s a tease, but it’s the first real chance.

Saturday 8th August – The morning stays small at 2ft, and the wind is a light cross-shore, which isn’t ideal. The afternoon picks up a bit of a cleaner cross-off breeze, but it’s still just 2ft with a 16 second period. Surfable, but ordinary.

Sunday 9th through to Thursday 13th – This is a real dry spell. The swell hangs around 1ft to 2ft, with periods dropping off. The winds are mostly cross-on or cross, and the conditions are poor. The energy drops right down, and there’s nothing to get excited about. The Thursday afternoon shows a tiny uptick in energy, but the surf is still poor. It’s a frustrating stretch.

Friday 14th August – Finally, a shift. The morning is still marginal with a 1ft, 19 second swell, but the energy jumps to 251. The afternoon is the real standout. The wind goes light and cross-offshore, the swell is still 1ft but the period is a very long 18 seconds, with a combined energy of 227. It’s clean, small, but the quality is there. This is the best on offer so far.

Saturday 15th August – The morning is the pick of the week. The swell bumps up to 2ft from the SSW, 16 seconds, with a light, glassy cross-offshore wind. The combined energy is 221. It’s clean, small, and perfect for a longboard or a fun board. The afternoon sees the swell rise to 3ft and energy hits 326, but the wind gets a bit stronger and the conditions become more marginal. Still, that morning session is the one to aim for.

Sunday 16th August to Wednesday 19th August – The swell holds around 2ft to 2ft, with periods from 15 to 16 seconds. The mornings are often a bit cross, but the afternoons consistently show a clean, cross-off breeze. The energy stays moderate, ranging from 139 to 225. It’s not firing, but it’s consistent, clean, and surfable. A solid run of small, clean waves.

Thursday 20th August to Saturday 22nd August – The pattern continues. The swell stays small, around 2ft to 2ft, with periods of 14 to 16 seconds. The afternoons continue to offer clean, cross-off conditions. The energy is moderate, with the Friday afternoon (21st August) showing a solid 230, and the conditions are clean. It’s the last real highlight in the window.

The Standout: It’s got to be the morning of Saturday 15th August. The swell is 2ft from the SSW, the period is 16 seconds, and that light, cross-offshore wind will have it glassy and clean. The combined energy is 221. It’s small, but for a point break like Rincon, that’s perfect. The Friday afternoon (14th) and Friday afternoon (21st) are also very clean options.

The water is running at 69°, which is much warmer than normal for this time of year – a good 6° above average. That’s a nice bonus.

This is a mellow run of small, clean groundswell. It’s more about the quality of the ride than the size. If you’ve got a log or a mid-length, you’ll be in business.

Rusty.
