Although weather experts rely on average temperatures over a longer period of time to predict the weather, there are often extreme weather conditions. 

The lowest temperature ever recorded on earth was at Vostok, a station in Antarctica. –89° C was measured in 1983 . The highest temperature was recorded in the Libyan desert in 1922 (57°C). The highest annual rainfall was measured in Cherrapunji, India, at the foot of the Himalayan mountain range. 26 metres of rain fell over a one-year period.
