  In Cairo, and along the Nile River Valley, the climate is a hot desert climate (BWh according to the Köppen climate classification system).
  
  Wind storms can be frequent, bringing Saharan dust into the city, from March to May and the air often becomes uncomfortably dry. Winters are mild to warm, while summers are long and hot. High temperatures in winter range from 14 to 22 °C (57 to 72 °F), while night-time lows drop to below 11 °C (52 °F), often to 5 °C (41 °F). In summer, the highs often exceed 31 °C (88 °F) but rarely surpass 40 °C (104 °F), and lows drop to about 20 °C (68 °F). Rainfall is sparse and only happens in the colder months, but sudden showers can cause severe flooding. The summer months have high humidity due to its coastal location. Snowfall is extremely rare; a small amount of graupel, widely believed to be snow, fell on Cairo's easternmost suburbs on 13 December 2013, the first time Cairo's area received this kind of precipitation in many decades. Dew points in the hottest months range from 13.9 °C (57 °F) in June to 18.3 °C (65 °F) in August.
