Bulgaria’s December 2025 has been similarly warm as the months of December since 2019, the national meteorological bureau said in a regular report.
Average monthly temperatures in December 2025 were between 2 and 7 degrees Celsius, deviating from the monthly norm between plus 1 and 4 degrees, the report said.
The highest measured temperature was 17.5 degrees on December 11 in Velingrad.
The lowest minimum temperature at a weather station in a settlement was minus 10.1 degrees on December 30 in Dragoman, and the lowest temperature measured on a mountain peak is minus 17.5 degrees on Musala Peak on December 29.
In Sofia, the highest measured temperature was 13.3 degrees on December 11, and the lowest, minus 5.2 degrees on December 30.
December 2025 has seen less precipitation than December 2024. The largest measured 24-hour precipitation was 82mm of rain in the village of Sestrimo, Pazardzhik district, on December 6.
In Sofia, the monthly precipitation was 29mm, which is 73 per cent of the norm, and the maximum 24-hour precipitation was 14mm of rain on December 25.
Snow fell on December 25 in northern Bulgaria, on the high fields of western Bulgaria and in the mountains, where snow cover formed with a height in places of up to 10–20cm.
The largest snow cover in a settlement was measured in the village of Kalenik, Vidin district, on December 26, a total of 28cm, and on a mountain peak, 84cm on Botev Peak on December 27.
As a result of intense rainfall on December 5 and 6, floods were registered in the Bourgas and Plovdiv districts. The most affected was the village of Zidarovo, Sozopol municipality, where on December 6, almost twice the monthly norm for the station was recorded in eight hours. Intense rainfall caused landslides of rock and earth masses on the Troyan-Karnare pass, in the area of the village of Karnare, and on the Assenovgrad-Smolyan road, near the village of Bachkovo.
On December 28, strong winds caused damage in several parts of the country. Fallen trees, branches, metal sheets and fences damaged the power grid and parked cars in many settlements. There was also damage to the contact network of the Sub-Balkan railway line between the Gurkovo and Tvarditsa stations. In Assenovgrad, the insulation from the facade of an eight-story residential building was pulled off by the strong gusts of wind.
During most of December, the water levels of the country’s rivers were around the average water levels.
At the beginning of winter, soil moisture reserves of autumn crops in the one-meter soil layer were very good – 85 to 90 per cent of the maximum field moisture capacity, the report said.
In the last days of the month, adverse events for agriculture were registered, such as floods in the area of the village of Gelemenovo, Pazardzhik municipality, and strong to hurricane-force winds in some regions of northern Bulgaria, which damaged fruit trees. The extent of the damage from these events is being clarified, the meteorological bureau said.
