Climate: Because of its position on the southeastern portion of the European continent, Romania has a climate that is transitional between temperate and continental with four distinct seasons.
Spring is pleasant with cool mornings and nights and warm days. In summer, the weather is hot and dry. The most affected areas are the South and the South-East where the thermometer usually exceeds 38°C during the months of July and August. Temperatures are lower in the mountains. Autumn is quite dry and crisp and the landscape revives of yellow and red leaves. Romanian winters can be extremely cold and foggy, in winter temperatures are especially harsh in the mountains (up to -25°C). Abundant snowfalls occur from December until April. The Carpathians mountains block the continental influences of the vast plain to the north in the Ukraine, which bring frosty winters and less rain to the south and southeast. In the extreme southeast, Mediterranean influences offer a milder, maritime climate. Annual precipitation averages about 630 millimeters in central Transylvania, 520 millimeters at Iasi in Moldavia, and only 380 millimeters at Constanta on the Black Sea.
Precipitation decreases from west to east and from the mountains to the plains, some mountainous areas receive more than 1,010 millimeters of precipitation each year.
