UAE weather: Temperature to gradually decrease in September
September is considered the last month of summer, according to weather forecasters
The UAE will witness a gradual decrease in temperature during the month of September as it is considered the last month of summer, according to weather forecasters.
In its climate report for September, which was released on Tuesday, the National Centre of Meteorology (NCM) said September is the month when temperature start coming down, especially during the night. It added that the second half of it, September 23, marks the beginning of autumnal equinox when the sun is directly perpendicular to the equator and then moves south towards the orbit of Capricorn.
The report said during this month, the effect of the Indian monsoon depression gradually weakens and the country feels the impact of desert thermal lows over Arabian Peninsula accompanied by relatively fresh winds causing dust with poor horizontal visibility at times. The frequency of occurrences of dust remains less compared to the previous two months.
“Southeasterly winds prevail during late nights and early mornings becoming northwesterly during afternoons and evenings due to sea breeze/land breeze circulation,” said the NCM report.
“Relative humidity increases slightly during this month, compared to August, especially during the second half of it. The average relative humidity is 49 per cent and as a result, the chances of fog/mist increase in different parts of the country.”
Forecasters said the eastern parts of the county will remain under the influence of Indian monsoon depression, particularly eastern mountains, which will lead to formation of cumulonimbus clouds associated with rain and thunder. It may extend to internal areas causing rain at different intensities.
