Climate Statistics, UAE 2019 Statistics describing climate include temperature, precipitation, humidity, pressure, wind speed,
solar radiation, and more. Climate is described by these elements over a long period for a specific
area. Weather phenomenon describe weather conditions over a specific area over a short period.
Weather conditions are usually recorded by countries through a network of monitoring stations
to monitor climate elements.
Important Notes: 1- The report contains statistics obtained from the National Center of Meteorology.
2 - The report includes the stations that managed by the National Meteorological Center
Key Points
During the period 2003-2019, the monthly average of the highest temperature recorded in
July reached about 35.8 ° C, and the highest average maximum temperature in July also
reached 42.2 ° C, and the lowest average minimum temperature in January was about 13.1 °
C.
In 2019, the highest monthly average temperature in June was 35.8 ° C, while the maximum
temperature reached 51.8 ° C in June making it the hottest month of the year, while the
lowest minimum temperature was 1.1 ° C in March.
The average amount of rain reached 101.1 mm in 2019, an increase of about 20.1 mm over
the annual rate for the years 2003-2019.
The highest average maximum relative humidity reached 86% in January, and its highest
average reached 64% in January as well. Minimum relative humidity reached its lowest levels
in the summer months, especially in May, when it reached 17%.
The highest value of air pressure in 2019 reached 1025 hPa at Al Ain Airport Station in
January, and most of the major state stations and airports recorded the lowest air pressure
in July.
The highest average wind speed of the main stations in 2019 was 20 km / hour, at Abu Dhabi
Airport Station in March, and the highest average wind speed was 44 km / hour in October
at Al Ain Airport Station.
The highest average hours of brightness were in June and July, and the average hours of
solar brightness for major stations is about 9.6 hours /day.
In 2019, most natural phenomena, such as fog, thunderstorms and sandstorms, occurred in
March surrounding most of the main stations.

Climate Monitoring Stations
The number of operational climate monitoring stations in 2019 reached 89, with an
increase of 13 stations over 2016.
These stations distributed in all the Emirates of the country, with more than 57% of
stations located in the Emirate of Abu Dhabi, where the total number of stations is to 51.
This is because Abu Dhabi is the largest Emirate in terms of area and the most diverse in
geographical nature.
The location distribution of the stations showed that the coverage sites are, land areas,
airports, islands and mountains. Land-based stations formed 81% of the stations,
followed by airports (8%) then mountain and islands stations (5.6%) for each of them.
This large number of stations and their distribution in all regions shows the interest of the
UAE in monitoring the elements of climate. The monitoring and assessing of these climatic
conditions is essential for the protection measures that taken, in regards to the UAE’s natural
resources.

The National Center of Meteorology data indicate that the monthly average temperature
during the years 2003-2019 was the highest in July and reached about 35.8 ° C, and the
highest average maximum temperature reached also in July reached about 42.2 ° C, and
the lowest average minimum temperature in January was about 13.1°.
Mean Temperature, by Month, 2003-2019
When comparing the monthly mean minimum temperature for 2019 with the average
minimum temperature for the past seventeen years (2003-2019), it was very close with a
slight increase in the summer months of June and September, while the same is true for
the winter months of January and December.

As for the average maximum temperature in 2019, it was slightly higher than the average
maximum temperature for the past seventeen years in June by 1.5 ° C in the summer
months and in January by 2.3 ° C above the average for the years 2003-2019.

Rainfall
Annual rainfall rates showed a great variation over the years 2003-2019, and there is
variation in the distribution of rain to different regions in the country.
The data showed that the rate of recorded rain in 2019 is twice the rate of rain in 2018, it
reached about 101.1 mm, it is about 20.1 millimeters higher than the annual average
amount of rain in the country (2003-2019.

Relative Humidity
The relative humidity average, minimum and maximum during the years 2003-2019
indicate a high humidity levels in the winter months. The highest maximum rate was 86%
in January, and the highest average reached 64% in January as well. The minimum
reached the lowest levels in the summer months, especially May. As it reached 17%, this
situation is consistent with increasing temperatures in summer months.

Daily Sunshine
The data showed that the highest average sunshine hours from the main stations in 2019
were in the months of June and July, and the average hours of solar brightness is about
9.6 hours / day.
Daily Average Sunshine Hours and Maximum hours in Main Stations by Month in 2019
The daily average of solar radiation in the main stations in 2019, the highest value was
recorded at the Dubai Airport in May, with a value of 9456 wh/m2, while the lowest was
at Ajman station in December and it reached 3553 wh/m2. The rise in the number of hours
of sunshine and the increase in solar radiation throughout the year indicates that there is
a large capacity to produce solar energy throughout the year in the country.
