Wow, that's bizarre (the weather). I live out near Parramatta and the southerlies here haven't been strong at all. According to my weather
data, max has been around 30km/h.
Many years ago, I used to spend holidays with my grandparents and visit Botany Bay quite often and I do recall
the sea state during strong southerlies. I thought it might have changed a lot since they dredged so much of the bay some years ago.
Ok, it's been MANY years since I have been to the bay....time flies when you get old(er).
