The climate in Saudi Arabia

Average daytime and nighttime temperatures

All climatic diagrams of this page are taken from the collected data from 27 measuring stations in Saudi Arabia.
Weather stations at an altitude above 2090m have not been included.
All data correspond to the average monthly values of the last 20 years.

Temperature records of the last 68 years

The hottest temperature measured from 1951 to December 2019 was reported by the Hufuf weather station. In August 2015 the record temperature of 50.0 °C was reported here. The hottest summer from July to September, based on all 41 weather stations in Saudi Arabia below 2090 metres altitude, was recorded in 2017 with an average temperature of 34.4 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 32.7 degrees Celsius. The average maximum daily temperature at that time was 41.6 °C.

The coldest day in these 68 years was reported by the weather station Buraydah. Here the temperature dropped to -2.4 °C in February 2017. Buraydah lies at an altitude of 648 meters above sea level. The coldest winter (January to March) was in 1983 with an average temperature of 14.9 °C. In Saudi Arabia, it is usual to have about 3.1 degrees more at 18.0 °C for this three-month period.

Long-term development of temperatures from 1991 - 2019

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 8 measuring points in order to have actually comparable data over as long a period as possible.

In the years 1991 to 2019 there were only these 8 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 Juli 2017 with 35.1 °C. Januar 1992 was the coldest month with an average temperature of 13.7 °C.

The average annual temperature was about 24.6 °C in the years after 1991 and about 26.4 °C in the last years before 2019. So in less than 29 years it has increased by about 1.8 °C. This trend only applies to the selected 8 weather stations in Saudi Arabia. A considerably more comprehensive evaluation of the global warming has been provided separately.
