Clean conditions for the early at Dee Why thanks to a steady WSW’ly and a small ESE wind swell. The buoy data is showing some longer period component in the mix and I suspect that accounts for the odd waist high set rolling in every now and again. We’ve got about a metre of 7 sec period ESE wind swell with some 11 second stuff as well.
Outlook for the rest of the day? There’s a divergence between the Bureau and some of the swell modelling, with the Bureau calling for the swell to increase later today to a couple metres from the SE. That’d be a good thing, particularly as those contrary models are showing it getting smaller before the south swell starts to ramp gradually from late tonight.
Tomorrow could see fun size at south spots as the south makes itself felt. And the rest of the week is looking promising – at least where the swell size is concerned. Wind is going to be a factor though, but I’m hoping it’ll be big enough to get into the protected corners from late Monday-early Tuesday.
Have yourself a great Saturday!

A low pressure system over the southern Tasman Sea with a trough to the north is deepening, while a high south of Western Australia extends a ridge to the Coral Sea. Between these two systems, much of the New South Wales coast will see vigorous southwesterly winds during the next few days, locally intensifying as a series of cold fronts pass to the south. The current pattern is very slow-moving, with the high expected to reach the Tasman Sea later next week.
