Cyprus has a Subtropical climate - Mediterranean and Semi-arid type (in the north-eastern part of island) - according to Köppen climate classification signes Csa and Bsh, with very mild winters (on the coast) and warm to hot summers. Snow is possible only in the Troodos Mountains in the central part of island.
Cyprus has one of the warmest climates (and warmest winters) in the Mediterranean. The average annual temperature on the coast is around 24°C (75°F) during the day and 14°C (57°F) at night.
Generally – the summer season lasts 8 months approximately, beginning in April with average temperatures of 21–23°C (70–73°F) during the day and 11–13°C (52–55°F) at night and ending in November with average temperatures of 22–23°C (72–73°F) during the day and 12–14°C (54–57°F) at night, although also in remaining 4 months temperatures often exceed 20°C (68 °F).
The height of summer (July and August) is usually hot, with temperatures on the coast averaging around 33°C (91°F) during the day and around 23°C (73°F) at night (inside the island, in the highlands, the average temperature exceeds 35°C (95°F)) while in the June and September on the coast the average temperature is usually around 30°C (86°F) during the day and around 20°C (68°F) at night.
The average annual temperature of the sea is 21–22°C (70–72°F), from 17°C (63°F) in February to 27–28°C (81–82°F) in August (depending on the location).
In total, for a period of 7 months, from May to November, the average sea temperature exceeds 20°C (68°F).
The hours of sunshine on the coast is 3,300 to 3,500 per year, for an average of 5-6 hours of sunshine per day in December to an average of 12-13 hours in July.
The higher mountain areas are cooler and wetter than the rest of the island. They receive the heaviest annual rainfall, which may be high as 1,000 millimetres (39.4 in). Sharp frost also occurs in the higher districts, which are usually blanketed with snow during the first months of the year.
Variability in annual rainfall is characteristic for the island. Statistical analysis of rainfall in Cyprus reveals a decreasing trend of rainfall amounts in the last 30 years.
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.
Relative humidity of the air is on average between 60% and 80% in winter and between 40% and 60% in summer. Fog is infrequent and visibility is generally very good.
Winds are generally light to moderate and variable in direction. Strong winds may occur sometimes, but gales are infrequent over Cyprus and are mainly confined to exposed coastal areas as well as areas at high elevation.
