🇲🇪Montenegro

Montenegro spans 41°51′–43°33′N as a small Western Balkan country (approximately 13,812 km²) on the Adriatic coast bordering Croatia, Bosnia and Herzegovina, Serbia, Kosovo, and Albania. An extraordinarily mountainous nation — the Dinaric Alps run parallel to a 295 km Adriatic coast featuring Europe's southernmost fjord, the Bay of Kotor (a UNESCO World Heritage karst inlet).

Inland rises to Bobotov Kuk in the Durmitor massif at 2,523 m and the country's highest peak Zla Kolata at 2,534 m on the Albanian border, surrounding glacial lakes including Black Lake, Plav, and Skadar — the largest lake in the Balkans on the Albanian border.

This produces a striking compressed climate spectrum — hot-summer Mediterranean (Csa) on the coastal strip (Bar, Budva, Kotor), warm-summer Mediterranean (Csb) on the karst hinterland, humid continental (Dfb) on the central plateaus (Podgorica is hot-summer continental), subarctic (Dfc) at high elevations, and tundra (ET) on the Durmitor and Prokletije summits.

Podgorica averages 5°C in January and 26°C in July with 1,650 mm rainfall almost entirely October–April — among Europe's wettest national capitals. Bar on the Adriatic registers 9°C in January and 25°C in July with 1,360 mm. Crkvice near Kotor receives a remarkable approximately 5,000 mm per year — among Europe's wettest stations. Žabljak in the Durmitor at 1,450 m records −5°C in January and 14°C in July with 1,400 mm and reliable winter snowpack supporting the country's small ski sector.

Kolašin averages −2°C in January and 17°C in July with 1,150 mm. Major events include the severe 1979 Adriatic earthquake compounded by climate hazards, recurrent severe wildfires (the severe August 2017 fires, the August 2019 Skadar Lake fires, the September 2024 Lustica Peninsula fires), the 2012 record −31°C cold-snap, the severe November 2010 Skadar Lake floods, intensifying summer heatwaves above 40°C in Podgorica, and accelerating Adriatic marine heatwaves and coastal salinisation.

Our archive covers 1 Montenegrin cities with daily ERA5 reanalysis data going back to 1940. The warmest July averages occur in Podgorica, around 30.3°C, while Podgorica records the coldest January nights near 2.3°C. Comparing the last decade against the 1940–1970 baseline, mean temperatures across these cities have risen by about 2°C.
