Frequently asked questions about Damascus's climate
How much warmer have summers in Damascus become?
The average daytime high across June, July and August rose by 2.2°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 Damascus become milder?
The average daytime high across December, January and February rose by 1.6°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 Damascus get a year?
Damascus averaged 134 days a year above 30°C in 2021-2025, up from 112 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 Damascus still get?
Damascus averaged 13 frost days a year in 2021-2025, down from 26 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 Damascus?
Spring now starts about 4 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 Damascus against itself rather than against other cities.
Has the growing season in Damascus grown longer?
The growing season is about 47 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 Damascus getting heavier?
Damascus averaged 0.2 days a year with more than 20mm of rain in 2021-2025, the same as 0.2 in 1976-1980. So the count of heavy rain days has held level here.
