The average monthly temperature in Lapland was approximately between 12 and 15 degrees Celsius, while in other parts of the country the range was around 14 to 17 degrees Celsius. The deviation of the average temperature was largely 0...-1 degrees, while in the east the deviation was -1...-1.7 degrees.

Hot temperatures exceeding 25 degrees Celsius were measured in Finland on a total of nine different days, which is seven days below the July average. The greatest number of hot days – a total of 5 – was measured in Kevo, Utsjoki. In most places, there were between 0 and 2 hot days. Compared to the long-term average, the number of hot days in the southern and central parts of the country was lower than usual in many places.

The highest temperature of the month, 29.2 degrees, was also recorded at Kevo in Utsjoki on 11 July. The lowest temperature in July was -2.9 degrees, recorded in Tulppio, Savukoski on the 3rd of the month.

Rains in late July broke records

The rainfall in July was higher than usual in the southern and central parts of the country, with unusually or even exceptionally high readings at many observation stations. In Lapland, precipitation levels were slightly below the long-term average. In the eastern parts of Finland, the unusually and exceptionally heavy rainfall was spread out more evenly over July, whereas in the areas of Jyväskylä and Multia, the rainfall that topped July records at observation stations came mostly around 28 and 29 July, bringing more than 100 millimetres of rain within 1 to 2 days.

Precipitation was highest during this month at the observation station in Pirttiperä, Multia at 210.1 mm. The lowest levels of precipitation were recorded in Fagerholm, Parainen at 24.3 mm. The greatest amount of precipitation observed in a single day was 103.3 mm measured in Pirttiperä, Multia on the 28th. The single-day rainfall in Pirttiperä is the 30th largest amount of measured daily rainfall in Finland’s measurement history at any observation station.

On the southern coast of the country and in the southwestern archipelago, July was normal or more abundant in terms of sunshine. In other parts of Finland, the number of hours of sunshine was lower than the long-term average at many stations.

Just over 15,600 cloud-to-ground lighting discharges were observed in July, which is about one quarter of the monthly average.
