The climate in Romania

Average daytime and nighttime temperatures

All climatic diagrams of this page are taken from the collected data from 47 measuring stations in Romania.
Weather stations at an altitude above 2510m have not been included.
All data correspond to the average monthly values of the last 20 years.

Back to overview: Romania

Climate zone: Moderate zone of the northern hemisphere

The climate in Romania widely corresponds to the German weather conditions. It is cold, wet and a few beautiful summer months are also happening. A beach holiday can also be enjoyed in the warmer season, but water temperatures will not reach much more than 23 °C. Due to the warmer temperatures the best time for traveling is from May to September. Winter athletes will find their favorite weather conditions from December to January.

Temperature records of the last 67 years

The hottest temperature measured from 1954 to June 2021 was reported by the Craiova weather station. In July 2007 the record temperature of 42.6 °C was reported here. The hottest summer from July to September, based on all 14 weather stations in Romania below 2510 metres altitude, was recorded in 2012 with an average temperature of 22.5 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 19.6 degrees Celsius. The average maximum daily temperature at that time was 29.5 °C.

The coldest day in these 67 years was reported by the weather station Sibiu. Here the temperature dropped to -29.0 °C in January 2017. Sibiu lies at an altitude of 444 meters above sea level. The coldest winter (January to March) was in 1954 with an average temperature of -4.6 °C. In Romania, it is usual to have about 5.6 degrees more at 1.1 °C for this three-month period.

The most precipitation fell in Juni 1985. With 9.7 mm per day, the Iasi weather station recorded the highest monthly average of the last 67 years. Incidentally, the region with the most rainfall for the whole year is around Caransebes. The driest region is near Sulina.

Long-term development of temperatures from 1991 - 2020

In contrast to single record values, a long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would give a falsified result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would already decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and falsifies the average again. The subsequent long-term development was therefore reduced to only 13 measuring points in order to have actually comparable data over as long a period as possible.

In the years 1991 to 2020 there were only these 13 weather stations in the whole country, which reported continuous temperature values. From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was 2012 with 25.4 °C. 2012 was the coldest month with an average temperature of -6.0 °C.

The average annual temperature was about 10.2 °C in the years after 1991 and about 11.8 °C in the last years before 2020. So in less than 30 years it has increased by about 1.6 °C. This trend only applies to the selected 13 weather stations in Romania. A considerably more comprehensive evaluation of the global warming has been provided separately.
