The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s in store for us. We’ve got a bit of a mixed bag on the horizon, so let’s get into it.
The first real surf on offer is a slow start, but things definitely build. The swell direction is from the South, which is a bit unusual for this spot. The water temp is about average for the time of year, so nothing too wild there.
Saturday, August 9th we start seeing some real potential. The swell picks up to around 5ft from the South, with a nice long period of 14 seconds. That’s proper groundswell energy. The combined energy is strong at 949. The wind is a cross-offshore breeze, which will keep the faces clean. This is a standout window for the more experienced surfer. It’s too big for the beginners, but a point break like this should handle that long-period swell nicely.
Sunday, August 10th the swell holds, but the wind shifts onshore, making it a bit of a battle. The energy is still there, but the quality drops.
Now, keep your eyes on Friday, August 14th. This is where the stars align. We’ve got a 5ft South swell with a 14-second period, and the wind is forecast to be light and offshore from the West. The combined energy is a solid 933. That’s clean, glassy conditions for the morning session. This is the best of the bunch for sure.
Saturday, August 15th is another beauty. The swell is 5ft from the South, good period of 13 seconds, and the wind is forecast to be glassy in the morning. The energy is up at 881. If you are looking for a clean, uncrowded dawn patrol, this is a prime target. The crowd can be around sometimes, but on a morning like this, you’ll be laughing.
After that, the forecast gets a bit messy. The wind turns onshore and the swell period drops off. We get a lot of poor surf conditions through to the end of the window. The last glimmer of hope is on Friday, August 21st with a tiny 3ft swell and glassy conditions, but it’s knee-high at best.
So, to sum it up: the real standouts are the Friday 14th and Saturday 15th. Get out there for those.
Rusty.
