A new November rainfall record has been broken in Southern Finland. Preliminary data shows the previous monthly record fell dramatically on Sunday. The Kymenlaakso region experienced historic rainfall levels that surpassed all previous measurements for this time of year.
Virolahti's Koivuniemi weather station recorded 79.0 millimeters of rain during November 16. This measurement shatters the previous November daily record that stood for over fifty years. The old record dated back to November 21, 1971, when Isojoki's Sarviluoma observation station measured 52.8 millimeters in one day.
Finland's all-time rainfall record remains from July 1944. That record saw Espoo's Lahnus area receive 198.4 millimeters of precipitation in a single day. The recent measurements in Virolahti represent the most substantial November rainfall ever documented in Finnish meteorological history.
Weather experts note that extreme rainfall events have become more frequent across the Nordic region in recent decades. Climate scientists point to warmer sea temperatures in the Baltic Sea as a contributing factor to increased precipitation in Southern Finland. The phenomenon affects both urban infrastructure and agricultural planning throughout the region.
Local authorities monitor such records closely because heavy rainfall impacts flood prevention systems and transportation networks. The Kymenlaakso region's topography makes it particularly susceptible to drainage challenges during extreme weather events. Municipalities across Southern Finland regularly update their climate adaptation strategies based on these changing patterns.
International readers living in Finland should note that autumn and early winter often bring the highest precipitation levels. The country's coastal regions typically experience more rainfall than inland areas. Understanding local weather patterns helps newcomers prepare for seasonal changes across different parts of the country.
What does this record mean for future weather expectations? Meteorological services continue to track these developments as part of broader climate monitoring efforts. The data contributes to improved forecasting models that benefit everything from agriculture to urban planning throughout the Nordic region.
