Amman has a semi-arid climate (Köppen climate classification BSk)with long, hot and dry summers and wet and cool winters with a mediterranean (dry-summer) rainfall pattern. It also has an influence of the continental climate because of its inland location and highland climatebecause of its high elevation. Amman's location and altitude has a profound effect on its climate. Spring is brief, mild and lasts a little less than a month, from April to May, with rain during the morning and the afternoons. High temperatures are around 15 °C (59 °F) to 20 °C (68 °F) and lows are sometimes less than 10 °C (50 °F) and several times even go near 0 °C (32 °F)causing several freezes. The temperatures vary though due to the differences in elevation across Amman.
Amman has moderate summers starting from mid June to mid September. Summer's high temperatures range from 25 °C (77 °F) to30 °C (86 °F), usually with low humidity and frequent cool breezes. Most summers are rain-free with cloudless skies during the noon period and a brief shower or fog during the night-time. The summer's pleasant temperatures can be disturbed by heat-waves that suddenly raise the city's temperatures to around 35 °C (95 °F) and in some rare but recorded cases to as high as 41 °C (106 °F) such as during the summer of 1999.
Winter usually starts in late November or early December and continues to late April. Temperatures are usually near or below 10 °C(50 °F), with snow usually falling a few times each year. Due to its high altitude above sea level, winter in Amman is usually one of the coldest in any major city in the Levant or south-east of Europe and the surrounding countries ]; winters are usually foggy with at least 120 days of heavy fog per year. Snowy winter storms occur several times around the city. Due to the difference in elevation, snow may accumulate in the western parts of Amman (an average altitude of 1000 m above sea level) when at the same
