This Autumn Was the Warmest Since Records Began at Prague Weather Station

Autumn this year was the warmest since records began at the weather station at the Clementinum complex in central Prague, according to data released on Tuesday by the Czech Hydro-Meteorological Institute.

The average temperature between September and the end of November was 13.6 degrees Celsius.

September and October were the warmest seen since records were first made in 1775; November’s temperatures were 1 degree Celsius above the average for the time of year.

The second-warmest autumn ever recorded was in 2006, with an average temperature of 13.2 degrees.

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

Thirty-three years of chosen weather characteristic measurements (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.

Weather station Clementinum is the oldest weather observation considered unique in Central Europe.

In Clementinum there are two meteorological boxes – a slat and iron-plate. The slat box measures temperature and air moisture on the first floor of the north side of the south annex.

The iron-plate box is on the roof flat at the east annex where a technical library is located. The amount of rainfalls and duration of sunshine are noted every day with the help of an apparatus called a heliograph.
