Egypt’s Meteorological Authority warns of thunderstorms, lightning, and potential flash floods across central and southern Sinai and the Red Sea governorate on Saturday, October 10, 2026, accompanied by autumn daytime warmth and morning fog in northern regions.
Autumn weather has settled across Egypt with a sharp division between moderate coastal conditions and scorching heat in the south. According to official forecasts published by forecasters, daytime temperatures reach a mild 28 degrees Celsius in Alexandria and 30 degrees in Cairo, while southern cities like Aswan climb as high as 39 degrees. Nighttime brings a distinct cool turn, pushing overnight lows down to 17 degrees in northern parts and 23 degrees in the south. Orman Ghanem, an atmospheric forecaster at the Early Warning and Prediction Center within the Egyptian Meteorological Authority, explained that conditions remain typical for this time of year due to an upper-level atmospheric depression that fosters cloud cover and blocks solar radiation during daytime hours. In televised remarks on the First Channel, she noted that the winds assist in mitigating the heat, allowing people to perceive temperatures as lower than the actual recordings. Forecasters expect this autumn pattern to persist through Wednesday, October 14, 2026, across the republic.

Flash Flood Warnings and Thunderstorm Risks in Sinai and the Red Sea
The meteorological agency issued urgent warnings for heavy rain that could escalate into flash floods in central and southern Sinai as well as parts of the Red Sea governorate. Forecasters noted a 40 percent probability of thunderstorm activity across central and southern Upper Egypt, accompanied by downward winds and lightning strikes in vulnerable areas. Precipitation varies geographically, with a 30 percent chance of light to moderate showers hitting northwestern coastal areas and northern Lower Egypt intermittently. Satellite maps additionally show active rainy thunderstorms lingering over sections of the Red Sea governorate. Minor rainfall chances ranging near 10 percent also extend toward northeastern coasts, southern Lower Egypt, and the Canal cities, occasionally reaching parts of Greater Cairo and northern Upper Egypt.
Travelers and residents in mountainous and coastal corridors are advised to maintain distance from torrent paths. Alongside the heavy precipitation risks, winds in parts of Greater Cairo, southern Sinai, Upper Egypt, and the southern Eastern Desert may stir up dust and sand, reducing visibility on open transit routes.
Morning Fog Disruptions on Northern and Delta Highways
Commuters heading out early faced thick water fog stretching from 4:00 AM to 8:00 AM. The dense mist blanketed roadways across northern Egypt, the Nile Delta, Greater Cairo, the Suez Canal cities, and central Sinai, prompting authorities to urge caution for motorists navigating low horizontal visibility.
Meanwhile, marine navigation conditions vary across regional waters.
