Uz River Valley climate, related to the entire surface of the basin of this river, allows the sensing of several climate shades, the major factors which have not introduced this variety being primarily its geographical location, relief complexity, and the main components of general circulation of the atmosphere. The climate in the western part of the city is specific to the medium elevation mountains of the Eastern Carpathians, and in the east part there is a depression climate (“sheltered” climate - no strong winds or particularly harsh frosts), accordingly to Dărmăneşti Depression area.
The annual average air humidity is 76%. Inside depression, due to construction and industry, are registered lower values of relative humidity 60-70%, while in the mountains values reach 80-84%.
Mistiness: is influenced by the relief that plays a moderating role in air and front masses. In the depression area, due to the shelter of the mountains, the air has decreased and leading to cloud breakup.
Precipitation: the rainfall is determined by the geographical position of the region and the relief so that the average annual amount is between 630-1000 mm, net differences appearing between the upper and lower Uz River Valley. Speaking of mountain altitudes up to 1500-1600 meters, the annual recorded rainfall is about 1000 mm of which 650 mm falls as snow, this layer maintaining up to 120-180 days. During the growing season the average amount of rainfall is 480 mm for lowland.
Wind conditions: are determined by the nature and frequency of baric systems and atmospheric circulation processes as well as the position of the mountains. The main direction of the wind is western with a frequency of 33.9% followed by 17.1% south-west frequency, then by 10.5% south-east, and by 5.3% north. The average wind speed is 2.7% m / sec., but as a curiosity of this the highest wind speed is attained by the north and north-west winds, and not the prevailing western winds. They sometimes reach speeds of 20 m / sec.
