Frequently asked questions about Sarajevo's climate
How much warmer have summers in Sarajevo become?
The average daytime high across June, July and August rose by 5°C between 1976-1980 and 2021-2025. That is a five-year average at each end rather than two isolated summers, so a single exceptional heatwave or cool summer does not drive the number.
Have winters in Sarajevo become milder?
The average daytime high across December, January and February rose by 3.5°C between 1976-1980 and 2021-2025. In many capitals in this dataset winter is changing faster than summer, which shows up most clearly in the frost-day count below.
How many days above 30°C does Sarajevo get a year?
Sarajevo averaged 33 days a year above 30°C in 2021-2025, up from 2 in 1976-1980. These are the days that set peak cooling demand and the days hospitals see heat complaints rise.
How many frost days does Sarajevo still get?
Sarajevo averaged 66 frost days a year in 2021-2025, down from 82 in 1976-1980. Fewer frost days sounds pleasant, but water pipes, heat pumps and garden planting are all sized for a cold season that increasingly no longer arrives.
Is spring arriving earlier in Sarajevo?
Spring now starts about 8.6 weeks earlier than in 1976-1980. The start point is the first day the trailing seven-day average high crosses 12°C, a fixed in-house measure used only to compare Sarajevo against itself rather than against other cities.
Has the growing season in Sarajevo grown longer?
The growing season is about 75 days longer between 1976-1980 and 2021-2025. That is the stretch between the start of spring and the first autumn night below freezing, which is exactly the window gardens, farming and pollen seasons run inside.
Is rainfall in Sarajevo getting heavier?
Sarajevo averaged 9.4 days a year with more than 20mm of rain in 2021-2025, up from 7.6 in 1976-1980. Warmer air holds more water vapour, so the same annual rainfall increasingly arrives in shorter, harder bursts, which loads drains and water storage more than the annual total suggests.
