“This autumn was one of the warmest in 247 years,” reports the Clementinum. The record holder is 2015
“This autumn, with its average temperature, ranked 14th to 16th out of 247 previous autumns since 1775, so it comfortably made it one of the ten warmest autumns in 247 years. Only about five percent of autumn was warmer than this year, “Said meteorologists.
The warmest autumn they recorded in Klementinum so far was in 2006 with an average temperature of 13.2 degrees. The coldest autumn was measured in 1786 with an average temperature of 5.8 degrees Celsius.
In November this year, the average monthly temperature in Klementinum reached 6.3 degrees. The deviation from the so-called normal from 1981 to 2010 was 0.9 degrees and compared to the long-term average of 1775-2014 it was 1.9 degrees higher. This year’s November thus ranked 42nd to 44th out of 247 previous November since 1775. It is thus among the 20 percent of the warmest November in the measurement period.
The warmest November since 1775 was measured in 2015 with an average temperature of 8.7 degrees, on the contrary, the coldest weather since 1777 prevailed this month in 858 with an average temperature of minus three degrees.
