The perception of hot and cold varies a lot from place to place, so it is subjective to a certain place, because the people living around the Equator will consider the weather to be hot if the temperatures are going 40 or 45 C degrees, while the people living around the Arctic circle will consider a temperature of around 20 to 25 degrees to be hot.
