The widest range of temperatures found in any country is the USA. In the continental US alone the temperatures easily exceed -50°C and 50°C in both directions (much colder if you include Alaska). The USA also has the largest temperature change ever recorded in a 24 hour period, at 57°C.

Merits of specific measurement systems aside, the USA is arguably the most representative single country on Earth when it comes to temperature and "how people feel". It has among the hottest, coldest, and most extreme temperature ranges ever recorded.
