The climate in Jordan varies considerably. As a general rule, the further the land is from the Mediterranean, the more temperature contrasts occur and the less rainfall there is. The average elevation of the country is 812 m (2664 ft) (SL). The uplands over the Jordan Valley, the Dead Sea and Wadi Araba Mountains and as further south as Ras Al-Naqab are dominated by a Mediterranean climate, while areas in the east and northeast of the country can be described as arid dry deserts. While the desert regions of the kingdom reach high temperatures, the heat is typically moderately warm with low humidity and a daytime breeze, while the nights are refreshingly chilly.
Summers, which last from May to September, are hot and dry, with average temperatures of about 32°C (90°F) and sometimes exceeding 40°C (104°F) between July and August. Winter, which lasts from November to March, is relatively cold, with average temperatures around 13°C (55°F). Winter also sees frequent showers and occasional snowfall in some of the higher elevations in the west.
