To paint a bit of a background here... I grew up in Kwa Zulu Natal, South Africa. A coastal province whose winter temperatures, seldom went below 16 degrees celcius. We spent winters in lightweight jerseys and jeans, with no scarfs, beanies or gloves in sight. Fast forward to my 20's and I moved myself to Johannesburg, slightly colder inland province of Gauteng. Temperatures in Winter reach an average maximum temperture of 16 degrees. Sometimes, and I mean sometimes the temperatures at night dipped (by maybe a couple of degrees ) and us Gautengers would exclaim how cold it was.
