Cloudy weather expected in UAE on Tuesday with rain probability and temperatures up to 45°C in Dubai

According to the bulletin from the National Center of Meteorology, clear or partly cloudy weather is expected in the United Arab Emirates on Sunday, July 5. Low clouds may appear over the eastern coast.

Temperature Regime in the Emirates

The air temperature in Abu Dhabi will fluctuate between 31°C and 40°C. Dubai is forecast to have a range of 33°C to 41°C, while Sharjah's temperature will be between 32°C and 40°C.

Wind and Sea Conditions

A light to moderate southwesterly or northwesterly wind will blow, occasionally strengthening to reach speeds of 35 km/h from a base of 10-25 km/h. In the Arabian Gulf, the sea will be slightly to moderately choppy, and in the Gulf of Oman—slightly.

Records and Summer Period

The highest temperature recorded in the country on Saturday was 48.1°C in Musayrah (Ad-Dhafra region) at 15:15 UAE local time. According to the Emirates Astronomical Society, the hottest and driest period of the year in the UAE, known as 'Jamrat Al Qayth' (peak summer heat), began on July 3 and will last until August 10, marking the most intense phase of summer on the Arabian Peninsula and in the UAE.

Recent Rainfall

Some areas of the UAE experienced rainfall on Friday, July 3, bringing residents a refreshing break from the intense summer heat. Video footage published by the Storm Center showed rain pouring down on the eastern coast towards the Fujairah and Khor Fakkan mountains, where the sky was covered with dark, overcast clouds, indicating the possibility of further showers in that area.

According to data from the Emirates Astronomical Society, the hottest and driest period of the year in the United Arab Emirates, known as 'Jamrat Al Qayth' (the peak of summer heat), starts on July 3 and will last until August 10. This period marks the most intense phase of summer both in the UAE and on the Arabian Peninsula.

Characteristics of the 'Jamrat Al Qayth' Period

Ibrahim Al Jarwan, Chairman of the Board of Directors of the Emirates Astronomical Society and a member of the Arab Union of Astronomy and Space Sciences, told Khaleej Times that 'Jamrat Al Qayth' begins with the rising of the first stars of the Gemini constellation over the eastern horizon until dawn.

During this time, daytime temperatures in coastal areas usually range between 41°C and 43°C, while in inland and desert areas, temperatures often exceed 45°C and 46°C. During heatwaves, temperatures in some inland areas can reach over 50°C.

Phases of Traditional Summer

Al Jarwan explained that this 40-day period represents the culmination of the traditional summer season and is historically associated with the harshest heat conditions and the driest weather in the region. He specified that traditional summer on the Arabian Peninsula is divided into three stages. The first begins with the appearance of the Pleiades star cluster, the second and strongest stage is 'Jamrat Al Qayth', marked by the rising of the Gemini stars, and the final stage occurs with the appearance of the star Suhail, which brings a period of high humidity that locals call 'Kattat Al Suhail.'

Weather Phenomena and Solar Influence

He noted that 'Jamrat Al Qayth' is characterized by extreme heat, dryness, and the spread of hot, dry desert winds known as 'samum'. According to Al Jarwan, the frequency of heatwaves during this period varies from year to year, with some summers experiencing more intense thermal events than others. He added that temperatures exceeding seasonal averages by approximately four degrees are usually classified as heatwaves.

Furthermore, he drew attention to the effect of direct sunlight on exposed surfaces, pointing out that metal objects and vehicles left under the sun for extended periods can heat up to 70°C. At the end of the 'Jamrat Al Qayth' season, the increase in humidity coming from the Arabian Sea due to trade winds can enhance atmospheric uplift over the Hajar Mountains, contributing to the formation of convective clouds. This period is also associated with the occurrence of mirages, dust waves, and localized weather activity, especially in mountainous areas.

According to the forecast from the National Center for Meteorology (NCM), on Tuesday, June 30, the weather in the north and east of the United Arab Emirates is expected to be clear or partly cloudy.

Wind and Dust

Light to moderate southwesterly and northwesterly winds are expected, occasionally strengthening in the western direction. This will lead to dust rising at a speed of 10 to 25 km/h, reaching up to 40 km/h.

Temperature Regime in Cities

In major cities, including Abu Dhabi, Dubai, and Sharjah, daytime temperatures are expected to rise to 41°C, 39°C, and 40°C, respectively. Nighttime temperatures in Abu Dhabi are forecasted at 29°C, while in Dubai and Sharjah they will drop to 30°C.

Humidity and Sea

The humidity level in Abu Dhabi will range from 35 to 80 percent, and in Dubai and Sharjah—from 40 to 80 percent. The sea in the Arabian Gulf will be slightly to moderately rough, and in the Gulf of Oman—lightly.
