The hottest temperature measured from 1949 to September 2022 was reported by the Dongola weather station. In June 2010 the record temperature of 49.6 °C was reported here. The hottest summer from July to September, based on all 27 weather stations in Sudan below 890 metres altitude, was recorded in 2015 with an average temperature of 31.4 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 29.9 degrees Celsius. The average maximum daily temperature at that time was 37.8 °C.
The coldest day in these 73 years was reported by the weather station Karima. Here the temperature dropped to 1.0 °C in February 2005. Karima lies at an altitude of 249 meters above sea level. The coldest winter (January to March) was in 1983 with an average temperature of 21.1 °C. In Sudan, it is usual to have about 3.7 degrees more at 24.8 °C for this three-month period.
The most precipitation fell in August 2020. With 15.6 mm per day, the Abu Na'ama weather station recorded the highest monthly average of the last 73 years. Incidentally, the region with the most rainfall for the whole year is around Damazine. The driest region is near Wadi Halfa.

Data basis and methodology

The data of the individual measuring stations are based on the archives of the German Weather Service, individual values averaged and supplemented by own elements. In order to determine a representative national average, average values were first calculated for each part of the country, which were then summarized at the national level. Thus, if a disproportionate number of weather stations are located in a small area, their number does not affect the national average.
