Egypt’s Meteorological Authority warns of unstable autumn weather, bringing scattered thunderstorms to southern regions and the Red Sea coast, alongside a marked temperature drop expected later in the week as a high-altitude low-pressure system moves across the Mediterranean.
Autumn in Egypt is entering a more volatile phase, bringing a mix of daytime warmth, nighttime chill, and localized storm warnings across multiple governorates. While the calendar remains firmly anchored in the first half of the autumn season, meteorological officials have pushed back against suggestions that winter has officially arrived.
Thunderstorm Warnings Along the Red Sea and Southern Upper Egypt
Current forecasts point to unstable weather patterns centered primarily on the country’s southeastern corridor. According to projections issued by the Egyptian Meteorological Authority (reported by regional news outlets), light to moderate rainfall—sometimes accompanied by thunder and lightning—is expected across the Red Sea mountain ranges.
The affected zones include the Halayeb, Shalateen, and Marsa Alam areas, as well as parts of southern Sinai, the Gulf of Aqaba, and the far reaches of Southern Upper Egypt. Forecasters have placed the probability of these convective storms at around 30 percent in specific pockets, warning residents and motorists to remain vigilant against sudden downdrafts and lightning strikes.
Temperature Trends and Nighttime Chill Across Greater Cairo
Daytime conditions remain warm to hot across northern governorates and Greater Cairo, where daytime maximum temperatures hover around 30 degrees Celsius. Yet the sharp diurnal range characteristic of the season is widening. Nighttime lows drop to roughly 20 degrees Celsius in the capital, and dip further into the 17 to 18 degree range in newly developed urban areas and open desert peripheries.
Meteorological specialists advise citizens to manage the temperature swings carefully without rushing into heavy winter garments.
We should put on an extra piece of clothing, but we shouldn't head straight for full winter clothes, because if I dress heavily, I'll feel hot during the day and cold at night, and that'll give me a cold. Manar
Incoming Mediterranean Low Pressure System and Expected Mid-Week Rain
A more pronounced shift is approaching from the north. Beginning Wednesday, the upper atmosphere will come under the influence of a surface and upper-level low-pressure system originating over the Mediterranean Sea. This atmospheric disturbance will intensify rainfall along the northern coast and parts of the northern Delta through Friday.
Wind activity is expected to pick up significantly on Wednesday, carrying dust and sand across parts of the Western Desert, northwestern coast, Greater Cairo, and northern Upper Egypt, which could temporarily restrict horizontal visibility on highways. Maritime navigation in the Mediterranean and the Gulf of Suez is also projected to face moderate to rough conditions.
| Region | Wednesday Forecast (High / Low) | Thursday Forecast (High / Low) |
|---|---|---|
| Greater Cairo & Delta | 31°C / 20°C | 28°C / 19°C |
| Northern Coast | 29°C / 20°C | 26°C / 20°C |
| Northern Upper Egypt | 33°C / 19°C | 30°C / 17°C |
| Southern Upper Egypt | 38°C / 23°C | 36°C / 21°C |
As the low-pressure system takes full effect, daytime temperatures across Greater Cairo are expected to slide downward by roughly two to three degrees by Thursday, settling near 27 to 28 degrees Celsius.
Morning Fog Disruptions on Agricultural Highways
In addition to wind and rain warnings, the national weather service has highlighted the return of morning fog. Dense water mist is projected to form between 4:00 AM and 8:00 AM on agricultural and high-speed routes connecting northern districts to Greater Cairo, the Suez Canal zone, central Sinai, and northern Upper Egypt.
Drivers using these corridors during early morning hours have been urged to reduce speeds and maintain safe distances. The state-run forecasting agency continues to update its daily bulletins as autumn weather shifts across the country.
