Colors of the following climate diagrams: Azerbaijan Armenia
Daily maximum temperatures
The highest daytime temperatures in Armenia are reached in August with an average of 28.0 °C. The coldest month, on the other hand, is January, with an average of just zero °C. In Azerbaijan, July is the warmest month, with 32.7 °C. There, it is coolest in January with an average of 7.9 °C.
Night time lows
At night, it cools down to varying degrees depending on the country and altitude. In Armenia, temperatures drop as low as -7.0 °C in January. The warmest nights are in July at 16.6 °C. In Azerbaijan, it is coolest at night in January at -2.8 °C and warmest in July at 20.0 °C. This corresponds to a cooling of 6.9 to 11.9 °C in Armenia and 10.5 to 14.6 °C in Azerbaijan.
The humidity of the air depends to a large extent on the air temperature. The warmer the air, the more water it can absorb. At a temperature of 25°C it is 23 grams per cubic meter, at 30 degrees it is already 26 grams. Therefore, the air humidity is given as a relative value to the temperature-dependent maximum amount. It becomes unpleasant when high humidity is combined with high temperatures.
Rain days per month
By definition, a rain day is a day on which at least 0.1 liters of precipitation per m² fall. This corresponds to a 1 square meter puddle in which the water stands 0.1 mm high — insofar as the water does not seep away or evaporate. So it does not have to rain all day long. May brings the most rainy days (11.9) in Armenia. With an average of only 4.5 days, August is the friendliest. In Azerbaijan, it rains most often in May with 7.4 days.
Precipitation amount per day
Depending on the season and the location of a country, the wind brings a varying amount of water with it. As a rule, the water evaporating in the oceans is absorbed and then transported inland. The greatest amount of rain (hail or dew are also forms of precipitation) in Armenia occurs in May, when about 2.5 liters per square meter fall per day. In Azerbaijan, the average amount of precipitation ranges from 0.7 liters per day in August to 1.7 in October. However, these are average values. If you consider that there are only 11.9 rainy days in Armenia in May, each of them accounts for about 6.2 liters.
Sunshine hours per day
With 2,592 hours of sunshine per year, Armenia is in the lead. The most hours of sunshine (10.9 per day) are in July. Azerbaijan falls into second place with only 2,227 hours. There the sun is visible in December for only 3.7 hours per day, so not hidden behind clouds.
