How does Sydney roll summer out and autumn in? Usually with one of these. Severe storms come most often during the shoulder seasons of spring and autumn, following long summer days. They arrive abruptly and violently, usually from the south – hence the local adage ‘buster’ to describe the accompanying wind. But one great thing about Sydney is that you have many vantage points to get spectacular views of them ominously approaching – often in cool forms like this UFO-shaped cumulonimbus. This is from the eastern suburb of Edgecliff – an apt name in more ways than one.
