^Isn't it actually painful to be out in weather like that? 0°C is hard for me to handle.
22.3°C and raining at 11am. Very sticky and humid.
I flew from Slovenia to Australia in December 2001. It was -10 C in Slovenia, blizzard conditions, but with a jacket on I was fine.
We had to change planes in Vienna and, because I was on a little plane for that connecting flight from Slovenia to Vienna, we had to walk down a stairway and across the tarmac to the terminal. It was -12C and blowing a very stiff breeze. That is the coldest experience of my life. That jacket really didn't help much. I felt that cold cut right through to my bones. I got pulled up by security when I got to Sydney airport, I was still wearing that jacket as I walked through the airport and it was over 30 degrees Celsius.
Living in Slovenia (with temperatures regularly around -10C in winter) I didn't dress any different for winter than I would for going to work in summer in Sydney, I just threw on a jacket and I was fine. Some people I worked with struggled with the cold and they needed long underwear and fur-lined shoes and gloves and they needed to layer up even under their jackets. Once you get inside a pub or restaurant or shopping mall or home that the heating is on and it's comfortable T-shirt weather.
Your hands and face take a few weeks to adjust to the cold air by improving your circulation.
