Greg, seeing at Clayton is typically good when clear. The currents come up straight off the ocean all day and then abate an hour after sunset. There is nothing of any height from the ocean to Clayton which is only 6km. In fact most nights I can hear the waves crashing on the beach at the mouth of the Murray. That is how still it gets there. The down side to all this though is that during winter there is a lot of time with cloud and summer fogs are not unheard of either. That said I managed to capture 14 images from there last year and considerably more the year before. So imaging close the ocean can be very good for seeing.
Swannie, gully winds are starting to give me the pip this year. These have disrupted many attempts to image Mars and Saturn this year. The waiting game can be very irritating at times.
