Frequently asked questions about Bishkek's climate
How much warmer have summers in Bishkek become?
The average daytime high across June, July and August rose by 1.3°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 Bishkek become milder?
The average daytime high across December, January and February rose by 2.9°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 Bishkek get a year?
Bishkek averaged 41 days a year above 30°C in 2021-2025, up from 28 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 Bishkek still get?
Bishkek averaged 133 frost days a year in 2021-2025, down from 140 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 Bishkek?
Spring now starts about 3.6 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 Bishkek against itself rather than against other cities.
Has the growing season in Bishkek grown longer?
The growing season is about 28 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 Bishkek getting heavier?
Bishkek averaged 1.8 days a year with more than 20mm of rain in 2021-2025, down from 3 in 1976-1980. This capital gets fewer heavy rain days now, which brings its own problems in a drying climate.
