I remember being in holiday in Broome (in the tropics) and it was so easy to tell a local from a tourist - we were in shorts and t-shirt and they were in jeans, long sleeve shirts and jumpers.
At the moment, the nights are getting down to 1 to 4C, days not reaching 20C. Cloud cover helps moderate the overnight lows but then you get rain. Summertime can bring a series of days over 40C and a few cooler days in the mid to high 30s. I can cope with the hot days but the hot nights make it hard to sleep. It needs to get below 25C for a reasonable rest
