Climate in Jordan



The climate in Jordan is semi-dry in summer with average temperature in the mid 30 °C (86 °F) (mid 90 °F) and relatively cold in winter averaging around 13 °C (55 °F). The western part of the country receives greater precipitation during the winter season from November to March and snowfall in Amman (756 m (2,480 ft) ~ 1,280 m (4,199 ft) above sea-level) and Western Heights of 500 m (1,640 ft). Excluding the rift valley the rest of the country is entirely above 300 m (984 ft)(SL). The weather is humid from November to March and semi dry for the rest of the year. With hot, dry summers and cool winters during which practically all of the precipitation occurs, the country has a Mediterranean-style climate. In general, the farther inland from the Mediterranean a given part of the country lies, the greater are the seasonal contrasts in temperature and the less rainfall.

Atmospheric pressures during the summer months are relatively uniform, whereas the winter months bring a succession of marked low pressure areas and accompanying cold fronts. These cyclonic disturbances generally move eastward from over the Mediterranean Sea several times a month and result in sporadic precipitation.

Most of the land receives less than 620 mm (24.4 in) of rain a year and may be classified as a semi dry region. Where the ground rises to form the highlands east of the Jordan Valley, precipitation increases to around 300 mm (11.8 in) in the south and 500 mm (19.7 in) or more in the north. The Jordan Valley, forms a narrow climatic zone that annually receives up to 900 mm (35.4 in) of rain in the northern reaches; rain dwindles to less than 120 mm (4.7 in) at the head of the Dead Sea.

The country's long summer reaches a peak during August. January is usually the coldest month. The fairly wide ranges of temperature during a twenty-four-hour period are greatest during the summer months and have a tendency to increase with higher elevation. Daytime temperatures during
