Introduction
In Libya, the climate is
Mediterranean in the thin coastal strip and
desert in the interior. Actually, although the temperatures on the coast are typical of the Mediterranean climate, the rainfall level is very low, semi-desert in Tripolitania and Cirenaica, and even desert in the Gulf of Sidra (or Sirte). Only in the hills near the coast of Cyrenaica (called
Jebel Akhdar), precipitation is between 400 and 700 millimeters (16 and 27.5 inches) per year, so much so that they are covered by a Maquis shrubland.
Along the
coast, which is the only plain area that receives non-sporadic rains, most of the rainfall occurs from October to early April, with a peak in December and January. The amount is usually low, between 200 and 350 mm (8 and 14 in) per year in Tripolitania and Cyrenaica, and between 100 and 200 mm (4 and 8 in) in the Gulf of Sirte (which is definitely desert in the southernmost part), while to the east of Cyrenaica, in the easternmost part of the coast, on the border with Egypt (see Tobruk), it drops again to around 100 mm (4 in). The rains on the coast are due to depressions coming from the Atlantic Ocean or the Mediterranean Sea, and between one depression and the other, there are long periods of good weather even in winter; since the period when the rain can fall is limited, during some years, a decrease in the winter rainfall may cause droughts, whose effects are felt until the following autumn.
In
summer, the sun shines and it almost never rains throughout Libya, although in the southern part, in full desert, some showers may occur because of the African monsoon, which affects the Sahel region in the warmest months, and whose extreme offshoots can sometimes arrive here. Along the coast, air humidity is high, though sea
breezes blow in the afternoon, relieving the heat. Actually, in summer, the northern winds blow even at high altitude, since they are due to the baric configuration of the region, with a high pressure system over the western part of the Mediterranean and a low pressure system on the eastern side, and that's why the Libyan desert is not as hot as the Algerian desert. The average maximum temperature in summer ranges from 30 °C (86 °F) along the coast, to 35/37 °C (95/99 °F) in the north-central inland area, to 40/41 °C (104/406 °F) in the south.
Throughout the year, but more often in spring and autumn, Libya can be affected by the
Ghibli, a hot and dry wind, which is able to raise dust and cause sudden increases in temperature; this phenomenon is even more evident along the coast, where it also produces a sudden drop in relative humidity, which here is generally high because of the influence of the sea. In these cases, the temperature can exceed 40 °C (104 °F) from April to October even on the coast, while in winter it can reach 30 °C (86 °F).
The coast
The main Libyan cities located on the coast (Tripoli,
Benghazi, Misrata) have a Mediterranean climate, with mild, quite rainy winters and hot, sunny summers, with highs in July and August around 30 °C (86 °F). In summer, as mentioned, the air is humid and the north wind prevails.
Tripoli
These temperatures are also recorded in the old quarters of Tripoli, however, in the meteorological station of the
international airport, which is located about 20 km (12 mi) further south, and therefore further from the sea and closer to the desert, the summer temperatures are much higher. Here are the average temperatures.

Between the cities of the coast, Tripoli, located in the western part, is the rainiest city, and receives 330 millimeters (13 inches) of rain per year, with a peak of 60/70 mm (2.4/2.8 in) per month between November and January. In Benghazi, rainfall amounts to 260 mm (10.2 in) per year, while in Misrata, near the dry Gulf of Sirte, it amounts to just 190 mm (7.5 in); in Sirte, in the gulf of the same name, it's about 180 mm (7 in), and in Tobruk, located in the east, it drops to only 110 mm (4.3 in).

About 20 km (12 mi) south of Tripoli airport we find el-Azizia, where the average of the July and August highs rises to 37/38 °C (99/100 °F), and where it was mistakenly assumed that the world highest record had occurred, due an incorrect measurement carried out in 1922.
Hill areas
Bayda
A special case is represented by
Bayda, located at 600 meters (2,000 feet) above sea level, on the hills of Cyrenaica, which receives 540 mm (21 in) of rain per year. Here, in winter, owing to the altitude, it can even snow during cold waves. Here is the average precipitation in Bayda.

South of Tripoli, there is a mountain range, the Nafusa Mountains, where there are some cities located at an altitude of almost 1,000 meters (3,300 feet), such as Nalut, Zintan, Lefren, Gharyan, which, in winter, are slightly colder than the same Bayda.
The desert
In the vast
desert regions of Libya, good weather prevails throughout the year. During winter, the temperature range is high, in fact, nights are cold (the temperature can drop to around freezing, and even a few degrees below in the north-central part), while days are pleasant, around 20 °C (68 °F). The daytime temperature exceeds 30 °C (86 °F) from April to October. In summer, the highest recorded temperatures are around 47/48 °C (117/118 °F). The rains are very scarce and sporadic, in the form of downpours: some areas can see no rain for years. The desert is almost everywhere uninhabited, except near the oases, which are fed by water springs emerging from underground, such as the oases of
Kufra and Sabha.
Sabha
Here is the average temperature of
Sabha, located at 400 meters (1,300 feet) above sea level, in central-western Libya, at 27 degrees north latitude.
