What’s driving change?
Bulgaria experienced a notable cluster of flood events in June and July 2026, with one active flood event recorded between July 19th and July 24th, representing 100% of the annual total for floods. This unusual concentration of events follows earlier severe storms and heavy rainfall in early June that caused widespread flooding in areas like Haskovo, Kazanlak, Veliko Tarnovo, and Blagoevgrad. These events highlight the impact of intense rainfall, which can quickly lead to urban flooding. You can track active extreme weather events at Extreme Weather tracker.

Shifting Seasons
Warm / cold seasonsKöppen Dfb · ContinentalHow spring and autumn have shifted in Bulgaria. Spring is defined as the date monthly temperatures first rise above the long-term annual mean (10.5°C, from 1940–1969); autumn is the date they fall back below it. Temperature swings 23.5°C peak-to-peak across the year - a classic four-seasons rhythm.

The headline panel also shows the long-term trend rate per decade and the warmest and coolest years on file.
Where does the climate data for Bulgaria come from?
Climate data for Bulgaria comes from Our World in Data, sourcing Copernicus ERA5 and HadCRUT5 (national temperature anomaly) and the Global Carbon Project via Our World in Data (CO₂ emissions), refreshed every month, when the upstream temperature and rainfall data are refreshed.
What is the climate baseline used on this page?
Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.
