Uppsala has one of the world’s longest series of weather observations. The observations date back to 12 January 1722 by Anders Celsius and his professor Erik Burman. Every day they went outside to record the temperature, air pressure and wind direction. Over the years many different people have contributed to the data series, and on 12 January 2022 the series will become 300 years long.
