As of the Winter of 2013, the coldest temperature ever recorded in Orlando Florida, was 19 degrees on January 21st 1985.
In the northern hemisphere it is the shortest day in terms of daylight and it is in winter, but it is normally not the coldest day. The colder days tend to be after that. In the southern hemisphere it would normally be a warm day.

In the winter the average coldest day is about -25 Fahrenheit
In the northern hemisphere, the winter solstice hits on 12/21 each year. This is the point when orbit and tilt of the earth's axis is at it's furthest point away from the sun. Typically this will be the coldest day, excluding meteorological changes local to where you are on that day.
It probably won't get colder than a -30 in the winter.
Today is the coldest day of the year.
The coldest day ever in Seattle was December 31, 1950. It was 0 °F!
I have seen different cultures use the terms in different ways, but in general winter is based on the length of the days, climatological winter is based on coldest temperature and meteorological winter is often used the same as climate winter, but based on picking the three months which are coldest on average, and always using those same three months for record keeping. There are other differences in how the terms are used, but mostly it is people splitting hairs, and does not matter. If you want more information check out wikipedia or the NPR article on meteorologic winter. Also note, because it takes time for the air over half the world to cool, there is a delay between the shortest day of the year, and the coldest average day of the year. Temperature keeps dropping after the shortest day of the year for a few weeks. You might think winter would run from six weeks before the shortest day, until six weeks after, or from before the coldest day until six weeks after, and in some places it does, but mostly it starts on the shortest day of the year. Some cultures define winter from the end of the growing season until the start of the next one, so like most basic words, there are a lot of definitions, so keep that in mind when explaining to your friends the version you think is correct. So winter, without any adjective, is usually astronomical winter, based on the length of the days. It usually runs from the shortest day of the year, around late Dec in the northern hemisphere, until the days are exactly 12 hours, around mid March. Meteorological winter is for record keeping, and is the three months that are usually the coldest, which in the northern hemisphere usually means Dec, Jan and Feb. Climatological winter is based on average temperatures, and I have seen it used the same way as meteorologic winter, but I have also seen it used for picking the coldest day of the year, and having winter go from six weeks before until six weeks after.
The temperature of a winter day at the North Pole is typically around -40.0°C as it is one of the coldest regions on Earth due to its high latitude and lack of sunlight during the winter months. Such extreme cold temperatures are common in polar regions.
Temperatures in June, the coldest month there, average -15 degrees C to -20 degrees C, according to its Wikipedia entry. June 21 is the first day of Winter in the Southern Hemisphere.
