Английская Википедия:Climate of Egypt
Egypt essentially has a hot desert climate (Köppen climate classification BWh). The climate is generally extremely dry all over the country except on the northern Mediterranean coast which receives rainfall in winter. In addition to rarity of rain, extreme heat during summer months is also a general climate feature of Egypt although daytime temperatures are more moderated along the northern coast.
Prevailing wind
The prevailing northwesterly wind from the Mediterranean Sea continuously blows over the northern coast without the interposition of an eventual mountain range and thus, greatly moderates temperatures throughout the year. Because of the effect, average low temperatures vary from Шаблон:Convert in wintertime to Шаблон:Convert in summertime and average high temperatures vary from Шаблон:Convert in wintertime to Шаблон:Convert in summertime. Though temperatures are moderated along the coasts, the situation changes in the interior, which is away from the moderating northerly winds. Thus, in the central and the southern parts, nighttime temperatures are very hot, especially in summers when average high temperatures can exceed Шаблон:Convert, as in Aswan, Luxor, Asyut or Sohag which are located in the deserts of Egypt.
Sand storms
Every year, sometime from March to May, an extremely hot, dry and dusty wind blows from the south or the southwest. This wind is called khamasīn. When the flow of dry air continuously blows over vast desert regions, it picks up fine sand and dust particles and finally results in a dusty wind which is generally felt in the periphery of the desert. When this wind blows over Egypt, it causes high temperatures to soar temporarily at dangerous levels, usually over Шаблон:Convert, the relative humidity levels to drop under 5%. The khamasīn causes sudden, early heat waves and the absolute highest temperature records in Egypt.
Rainfall
Egypt receives between Шаблон:Convert and Шаблон:Convert of annual average precipitation along the narrow Mediterranean coast, but south from Cairo, the average drops to nearly Шаблон:Convert in the central and the southern part of the country. The cloudiest, rainiest places are in and around Alexandria and Rafah. The sunshine duration is high all over Egypt, ranging from a low of 3,300 hours along the northernmost part in places such as Alexandria to reach a high of over 4,000 hours farther in the interior, in most of the country.
Mountainous areas
Some mountainous locations in Sinai, such as Saint Catherine, have cooler night temperatures, due to their high elevations. It usually snows on the Sinai mountains, but it almost never snows in the cities of Giza, Cairo, and Alexandria. For example, in December 2013, Cairo received a single overnight snowfall for the first time since 1901.
