The Lowdown
Righto, let’s have a look at what’s comin’ through for the Cozies and Geeries region.
First up, we’ve got a real slow start here. For the first few days, the ocean’s a bit of a mess. Monday the 10th is a write-off – rain showers and a strong cross-on breeze (25 mph) making for poor, messy surf. You wouldn’t wanna paddle out there. That afternoon doesn’t look much better with marginal conditions.
But then, Tuesday the 11th, we start to see something worth getting out of bed for. The wind swings to a cross-off S’ly breeze at 12 mph, and the swell cleans right up. We’re looking at a solid 11.5 ft groundswell from the WSW with a very long period of 16 seconds. The wave energy is pumping (5815). This is big, powerful stuff – definitely not for beginners. Over 8 ft, this is only for the experienced crew. The breaks here are a reef and point setup, which is exactly what you want for this kind of long-period groundswell; it’ll wrap in nicely and won’t just close out. Tuesday afternoon holds similar quality with a 10 ft swell. This is the standout window of the whole outlook. Get on it if you’ve got the skills.
Wednesday the 12th is a bit of a mixed bag. The morning’s got a light cross-on breeze, but the afternoon cleans right up with a cross-off breeze and 6.9 ft swell. It’s still good, but not the standout like Tuesday. Thursday the 13th is a beauty for the experienced surfer – glassy conditions in the morning with a light E’ly breeze (5 mph) and a 6.9 ft, 17-second groundswell. That’s as clean as it gets. The water temp is sitting at 65.8°, which is about average for this time of year.
Friday the 14th keeps the clean cross-off winds and solid 6.5 ft+ swell, so you’ve got a good run of fun waves for the experienced guys right through the middle of the week.
Now, we hit a bit of a lull from Saturday the 15th onwards. The swell drops below 6 ft and the winds get messy again – cross-shore and choppy. Nothing really worth writing home about until we get to the following week.
Sunday the 17th of August has a pulse of bigger swell (10 ft, 17-second period) but the wind is messy again in the morning. The afternoon cleans up with a cross-off S’ly, and that could be a solid session for the crew who know what they’re doing. It’s over 8 ft, so keep it to the experts.
The rest of the second week is a bit of a saga. Big, powerful swells (10 ft to 16 ft) but they’re getting hammered by strong winds. Monday 24th might offer a window with a 8 ft to 10 ft swell and lighter breezes, but it’s far out and the confidence is low.
Overall, the clear standout is Tuesday 11th. That’s the day to circle. The long-period groundswell, the clean cross-off wind, and the reef/point setup are a perfect match. For the experienced surfer only.
