Temperature records of the last 73 years
The hottest temperature measured from 1949 to March 2022 was reported by the Ouargla Airp weather station. In July 2018 the record temperature of 51.3 °C was reported here. The hottest summer from July to September, based on all 80 weather stations in Algeria below 1360 metres altitude, was recorded in 1966 with an average temperature of 29.9 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 28.0 degrees Celsius.The coldest day in these 73 years was reported by the weather station Mecheria. Here the temperature dropped to -13.8 °C in January 2005. Mecheria lies at an altitude of 1150 meters above sea level. The coldest winter (January to March) was in 1992 with an average temperature of 10.1 °C. In Algeria, it is usual to have about 1.8 degrees more at 11.8 °C for this three-month period.
The most precipitation fell in November 1988. With 15.9 mm per day, the Guelma 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 Jijel Port. The driest region is near Ain Salah Airp.
Long-term development of temperatures from 1991 - 2021
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 7 measuring points in order to have actually comparable data over as long a period as possible.In the years 1991 to 2021 there were only these 7 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 August 1999 with 31.4 °C. January 2005 was the coldest month with an average temperature of 8.9 °C.
The average annual temperature was about 19.8 °C in the years after 1991 and about 20.8 °C in the last years before 2021. So in less than 31 years it has increased by about 0.9 °C. This trend only applies to the selected 7 weather stations in Algeria. A considerably more comprehensive evaluation of the global warming has been provided separately.
