See the direction that the boats face? That tells you what the temp is gonna be like. Hubby's apartment faces east. If the anchored boats point north, it means that the winds are coming in from the north, the outback, so it's warm. If they point south, it means that the winds are coming in from the south, Antartica, so it gets cold. It can change several times a day. For example, today the high was 74 F. Tomorrow the high will be 100 F. Crazy.
Why do so many people anchor their boats? Because it's cheaper than paying for a slip at the marina.
Hubby says that in the summer in Oz (which is now), there are daily sailboat races in the huge bay. Aussies are big beer drinkers. They watch the races and drink James Boag (a Tasmanian beer) while watching the races.
TMI but I think this is very interesting (how weather dramatically changes there) and I'm bored.
