The Lowdown
G’day, Rusty here. Alright, let’s have a look at what’s coming our way.
The next week and a half has a solid pulse of WSW groundswell, but the wind is going to be a real character. We start with a bit of a messy Tuesday, but things clean up nicely from Thursday onwards.
First up, Cozies and Geeries is your only option on the cards, a reef and point setup that’s fairly consistent but exposed to that swell. The water temp is 64°, about average for this time of year – nothing wild, just your usual winter temp.
Tuesday the 18th is a write-off. We’ve got 12ft of W swell with a very long 16-second period, but the cross-on wind from the west is going to chop it up. The combined wave energy is a massive 6388, but it’s not going to be pretty. Best to give it a miss.
Wednesday the 19th is still average. The swell drops a bit to 8ft-10ft, still with that long period (15 seconds) from the WSW. Wind is cross or cross-on, so it’s choppy. Not your day.
Now, Thursday the 20th is where it starts to get interesting. The swell is 8ft from the WSW, period still a juicy 16 seconds, but the wind goes glassy in the morning – dead calm. That is a big positive. The combined energy is strong at 3594. This is for experienced surfers as the swell is over 8ft, but if you’re up for it, those early morning waves will be clean and lined up. Thursday afternoon stays clean with a light cross-off breeze.
Friday the 21st keeps the clean theme. Swell eases to 7ft from the WSW, 15-second period, with light E to S winds. Another solid morning session on offer. The energy is moderate (2087).
Saturday the 22nd is a real standout. Morning glass again, 7ft WSW swell, 16-second period – perfect conditions. It’s still a bit much for beginners, but for anyone comfortable in that size, this is the pick of the week. The energy is moderate (2094).
Sunday the 23rd holds well. Clean morning with 5ft-6ft WSW swell. Wind is light cross-off. A very solid, user-friendly day for intermediate surfers.
Monday the 24th sees the wind turn cross-on, dropping the quality. Surf is still 5ft-6ft, but it’s choppy. Not great.
Tuesday the 25th is a write-off. A near gale from the WSW with 7ft-8ft of short-period, wind-affected junk. The energy is moderate but the quality is zero.
Wednesday the 26th through Friday the 28th is a messy stretch. The swell stays around 5ft-8ft, but it’s cross-shore and lumpy, or blown out. Not worth paddling out.
Then we get another little window. Saturday the 29th – clean conditions return in the morning. 6ft WSW swell, 16-second period, light wind. A nice little reprise. Energy is moderate (1632).
Sunday the 30th – morning glass again. 6ft swell from the W, 15-second period. This is another one to circle on your calendar. Very clean, long lines.
Monday the 31st – more glassy morning conditions. 8ft from the W, 16-second period. Strong energy (2861). Experienced surfers only again, but the conditions will be epic.
The first two days of September drop off in quality as the wind turns cross-on again, with swell still around 8ft-10ft but choppy.
So, the real standouts are Thursday the 20th, Saturday the 22nd, Sunday the 30th, and Monday the 31st – all offering clean, glassy mornings with decent WSW groundswell. Saturday the 22nd is probably the best all-rounder for the average surfer.
Rusty.
