Prague’s Klementinum Records Sixth Warmest Autumn Since 1775

This autumn in Prague was among the warmest ever recorded at the Klementinum weather station.

The period from September through November 2024 ranked as the sixth to eighth warmest since measurements began in 1775.

The average temperature during this time reached 12.1°C, which is 1.1°C above the 1991–2020 average, according to the Czech Hydrometeorological Institute (ČHMÚ).

The record-holder for the warmest autumn remains last year, with an average temperature of 13.6°C, while the coldest autumn occurred in 1786, with a mere 5.8°C average.

An Exceptional Warm Trend

“This year’s autumn ranks within the top 4% of the warmest autumns recorded over the past 250 years,” meteorologists noted. Seven of the eight warmest autumns in Klementinum’s history have been recorded in the 21st century, highlighting the recent trend of rising temperatures.

September and October this year were particularly warm, while November fell within the “normal” temperature range. November’s average temperature of 5.5°C placed it between 77th and 82nd out of 250 Novembers recorded since 1775.

“Approximately one-third of past Novembers were warmer, while two-thirds were colder,” the Czech Meteorological Institute stated.

The warmest November on record at Klementinum occurred in 2015, with an average temperature of 8.7°C. By contrast, the coldest was in 1858, when temperatures plunged to an average of -3°C.
