The Mediterranean climate, warm and rather dry, with rainfall mainly between November and March, favors agriculture. In general, the island experiences mild wet winters and dry hot summers. Variations in temperature and rainfall are governed by altitude and, to a lesser extent, distance from the coast. Hot, dry summers from mid-May to mid-September and rainy, rather changeable winters from November to mid-March are separated by short autumn and spring seasons.
   In summer the island is mainly under the influence of a shallow trough of low pressure extending from the great continental depression centred over southwest Asia. It is a season of high temperatures with almost cloudless skies.
   In winter Cyprus is near the track of fairly frequent small depressions which cross the Mediterranean Sea from west to east between the continental anticyclone of Eurasia and the generally low pressure belt of North Africa. These depressions give periods of disturbed weather usually lasting for a day or so and produce most of the annual precipitation, the average rainfall from December to February being about 60% of the average annual total precipitation for the island as a whole, which is 500 mm.

The higher mountain areas are cooler and moister than the rest of the island. They receive the heaviest annual rainfall, which may be as much as 1,000 millimeters. Sharp frost also occurs in the higher districts, which are usually blanketed with snow during the first months of the year. Precipitation increases from 450 millimetres up the south-western windward slopes to nearly 1,100 millimetres at the top of the Troodos massif. The narrow ridge of the Kyrenia range, stretching 160 km from west to east along the extreme north of the island produces a relatively small increase in rainfall of around 550 millimetres along its ridge at an elevation of 1,000 metres. Plains along the northern coast and in the Karpass Peninsula area average 400 to 450 millimeters of annual rainfall. The least rainfall occurs in the Mesaoria, with 300 to 400 millimeters a year. Variability in annual rainfall is characteristic for the island, however, and droughts are frequent and sometimes severe. Statistical analysis of rainfall in Cyprus reveals a decreasing trend of rainfall amounts in the last 30 years. Earthquakes, usually not destructive, occur from time to time.
   Rainfall in the warmer months contributes little or nothing to water resources and agriculture. Autumn and winter rainfall, on which agriculture and water supply generally depend, is somewhat variable from year to year.
