Finland's hottest city is actually its most inland one
In short: You might expect Finland's highest temperatures to occur on the coast, where the sun hits the water. However, Kouvola defies this logic. Because it sits further inland, it escapes the cooling marine effect, making it one of the hottest spots in the country during the summer months.
Kouvola experiences a humid continental climate (Dfb), characterized by four distinct seasons and relatively uniform precipitation throughout the year. While the city maintains a significant amount of rainfall even in its driest months—where precipitation stays above 30 millimetres—the distribution of heat and cold is dictated by its geography.
The city's inland location creates a distinct thermal profile compared to coastal regions. In the summer, the absence of the sea's cooling influence allows temperatures to rise more sharply, leading Kouvola to record the most days with "helle" (temperatures exceeding 25 °C or 77 °F) in Finland since 2000. Conversely, this same inland positioning results in harsher winters; without the moderating marine effect, the city faces colder temperatures than its coastal neighbors. The average annual temperature sits at 5.4 °C (41.7 °F).
The extremes of this climate are notable. On 28 July 2010, the station hit a peak of 34.5 °C (94.1 °F), whereas a record low of −37.3 °C (−35.1 °F) was also noted. This climatic variability, combined with over 1,658 hours of annual sunshine, shapes the region's environment, from its 450 lakes to its role as a major industrial hub.

S1:p20 The city is considered one of the hottest in Finland because it has had the most days with temperatures above 25 °C since 2000.
S1:p20 Winters are colder than coastal areas because the marine effect does not affect the city as much. A maximum of 34.5 °C was registered at the site during 28 July 2010.
