No, we don't have snow where I live at Christmas time, it's summer.
Living in the Southern area of Australia we have a hot 1pm meal, called Christmas Dinner. People do have Barbecues, some have salads, some eat out for Dinner, many go to family and spend a fair bit of the day travelling, some stay at home, some have Christmas Dinner another day, then some don't do much at all. So with our weather Christmas is not always a hot meal.
The photos below is from an Australian Christmas Card which basically shows the opposite to the Northern Hemisphere's Christmas weather.
