This Autumn Was One the Warmest in Prague's History

This year Prague saw one of its warmest autumns in the past 248 years, the Czech Hydro-Meteorological Institute reported on Saturday.

The average temperature from the beginning of September to the end of November reached 11.5 degrees Celsius, 1.7 degrees higher than the long-term average from 1775 to 2014.

The warmest autumn ever recorded 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 the last 30 years, the coldest autumn was recorded in 1993 with an average temperature of 8.8 degrees Celsius, which ranked 42nd to 45th in the overall ranking,” the CZMU officials noted.

Prague experienced its warmest November since 1775 in 2015, with an average temperature of 8.7 degrees, while the coldest weather since 1775 prevailed this month in 1858 with an average temperature of minus three degrees.

The meteorological autumn lasts from September to November, while the astronomical autumn from the autumnal equinox at the end of September to the winter solstice, which is Dec. 21 of this year.

In 1752 the first regular meteorological measurement was initiated at Klementinum and it has been continuing until now.

33 years of chosen weather characteristic measurement (temperature and air pressure) are unfortunately incomplete because they were often done by estimation.

So the year 1775 is considered the beginning of comprehensive succession. “Mannheim clocks” functioned as regular temperature measurements, according to which weather behaviour was noted always at 7 am,7 pm, and 9 pm.

Interesting fact! The Klementinum weather station was the first in Central Europe, work on the study of weather conditions began here in the middle of the 18th century, air temperature measurements were carried out daily. In this weather station, Keller discovered the laws of the movement of the bodies.
