Chilly Weather Replaces July Heatwaves in Helsinki

Helsinki experienced a sharp temperature drop on Tuesday, July 21, as chilly drizzle replaced the expected July heat. The mercury fell to a low of 10.6 degrees Celsius at Helsinki-Vantaa Airport, with other parts of the capital region also seeing temperatures near 10 degrees.

Meteorologist Petri Hoppula of the Finnish Meteorological Institute anticipates temperatures to hover around 14-15 degrees Celsius on Wednesday and Thursday. This is considerably lower than the typical July average of 16 degrees, a month usually characterized by the best summer weather.

While July typically offers warm conditions, there have been exceptions. For instance, July 2015 saw only a couple of hot days. The current cold snap is not considered an unusual phenomenon, as July's lowest temperatures can sometimes approach the warmest days of December or February. The Meteorological Institute explains that a low-pressure system over Finland is drawing cold air from the Kola Peninsula, influencing these temperature fluctuations.

The drizzle itself carries cold air from the upper atmosphere, while warm weather often flows north from Europe, where warm air masses tend to linger.
