Temperatures reach 36 to 39 degrees Celsius in southern cities while Cairo hovers near 30 degrees Celsius as the Egyptian Meteorological Authority warns of thundery showers, lightning, and sudden downdrafts in southern mountain ranges and Upper Egypt.
Autumn weather holds steady across most Egyptian governorates, bringing mild days to northern regions and lingering high heat to the south. Government forecasters report that daytime temperatures in Cairo reach roughly 30 degrees Celsius, with southern cities such as Aswan recording highs between 36 and 39 degrees Celsius.
Thundery Showers Threaten Southern Sinai and Red Sea Mountains
While northern cities experience typical seasonal warmth, intermittent light to moderate thundery showers target the southern Red Sea mountain ranges, including Halaib, Shalatin, and Marsa Alam, alongside parts of southern Sinai and the Gulf of Aqaba. Forecasters note that these active cloud formations carry a 30% probability of occurrence in specific southern pockets and could extend toward the far south of Upper Egypt.
Meteorologists warn residents and motorists in mountainous regions to exercise caution. Strong downdrafts beneath storm cells and frequent lightning strikes pose localized risks, while low-lying wadis face potential flash-flood hazards.
Morning Fog Sweeps the Governorates
Early morning commuters encounter patches of water fog reducing horizontal visibility on agricultural, desert, and water-adjacent roadways between 4:00 AM and 8:00 AM, particularly across northern governorates, Greater Cairo, the Suez Canal cities, and central Sinai.
The transition between autumn daytime warmth and late-night cooling remains pronounced. Overnight lows drop to approximately 19 to 20 degrees Celsius in Cairo, while outlying new cities and open areas dip further to between 17 and 18 degrees Celsius, prompting officials to advise light outer layers for evening and early morning hours.
Upper-Air Low Pressure Approaches Wednesday
Atmospheric conditions are set to change on Wednesday when an upper-air trough converges with a surface low-pressure system over the Mediterranean Sea. This system will intensify precipitation along northern coastal areas, including Alexandria and Matrouh, through Friday.
The incoming disturbance will also generate wind-driven marine disruptions across the Red Sea and the Gulf of Suez, where wave heights reach up to 2.5 meters, alongside a general temperature decrease toward the end of the week.
