Division

Geologically and morphologically Pirin is divided into three parts: north, central and south, which differ sharply in size and altitude. North Pirin is the largest of the subdivisions and the mountain's downright part. It takes up 74% of the whole range's territory, being about long and ranging from Predel to the north to the Todorova Polyana Saddle () to the south. It is the most often visited part of the mountain, the only one to have an Alpine appearance, featuring many glacial lakes, resthouses and shelters. North Pirin is itself divided into two zones by the Kabata Saddle and the valleys of the Banderitsa and Vlahinska rivers. The northern zone consists of the steep

The highest peak is Orelyak (), while the other summits are under . South Pirin stretches from the Popovi Livadi Saddle to the Paril Saddle and is the lowest and least rugged part. The highest peak is Ushite at , although Sveshtnik () had long been considered the highest summit. It constitutes 19% of the mountain's territory. Despite being characterised with relatively flat ridges, its lateral slopes are steep. South Pirin is composed of granite with marbled limestone in the periphery. It lacks glacial forms and is covered with forests. Like Central Pirin, the springs are short and with low water discharge.

There are many spurs but four of them are so large that they create the appearance of the mountain: Sinanishko, Todorino, Polezhansko and Kamenishko. There are two peaks above , Vihren and Kutelo; seven above ; 13 above ; 32 above and 60 above . The highest granite peak is the Banderishki Chukar ().

Climate

Pirin is situated within the continental Mediterranean climate zone and due to its altitude the higher sectors have

Alpine climate Alpine climate is the typical climate for elevations above the tree line, where trees fail to grow due to cold. This climate is also referred to as a mountain climate or highland climate. Definition There are multiple definitions of alpine cli ...

. The climate is influenced by Mediterranean cyclones mainly in late autumn and in winter, bringing frequent and high rainfall, and by the Azores anticyclone in summer, making the summer months hot and dry. The relief has a crucial influence on the climate. Pirin has three altitude climate zones — low between 600 and 1,000 m, middle between 1,000 and 1,800 m and high above 1,800 m. The low altitude zone is heavily influenced by the Mediterranean climate, the influence being more pronounced on the western slopes facing the Struma valley than on the eastern slopes along the Mesta valley. The high altitude zone is characterised by low temperature, low temperature amplitude, many cloudy days, lasting and thick snow cover, strong winds and intensive sun radiation. Winters are cold and prolonged while summers are cool and short. The temperature decreases with the altitude, which is more visible in summer. The mean annual temperature is around 9–10 °C in the low, 5–7 °C in the middle and 2–3 °C in the high altitude zone. The coldest month is January with average temperature varying between −5 and −2 °C. The hottest month is July with temperature averaging 20 °C at 1,600 m and 15 °C at 2,000 m. Temperature inversions, i.e. increase in temperature with height, are observed in 75% of the winter days. The annual precipitation in Pirin is 600–700 mm in the lower zones and 1000–1200 mm in the higher. The rainfall occurs mostly in winter and spring, while summer is driest season. The air humidity is 60–75% in August and 80–85 % in December. In winter the precipitation is mainly snow, varying from 70–90% at the lower altitudes to 100% at higher. The average number of days with snow cover varies from 20–30 to 120–160. The highest thickness of the snow cover reaches 40–60 cm at 1,000–1,800 m in February and 160–180 cm above 1,800 m in March (190 cm on Vihren). In some winters the snow thickness can reach 250–350 cm.

s are frequent. The prevailing wind direction is from the west and the north-west but southern and south-western winds are also frequent. The wind speed can reach 34–40 m/s at the high ridges, being highest in February and March and lowest in August and September. The percentage of windless days increases in summer and autumn to 30–40% at lower altitude and 10–15% at higher. In the highest zone the percentage does not exceed 5–7% annually.

Hydrology

Pirin forms the water divide between the basins of the rivers Struma and Mesta. The watershed follows the main ridge of the mountain in direction north-west to south-east. As the main ridge is situated closer to the Mesta valley, the tributaries to the Struma tend to be longer. The rivers are short, steep and with high water volume; the river bottom is rocky or covered with large sediments. The water discharge is highest in May and June and lowest in September. The streamflow is largely derived from snow melting and glacial lakes in spring and summer and almost exclusively from groundwater in winter. The rivers and streams form numerous leaps and waterfalls but they are generally not as high as those in

The vegetation of Pirin is vertically divided into five distinct elevation zones: Mediterranean, deciduous, coniferous, that combined form the ''tree line'' reaching approximately altitude of 2,000 m, shrubs forming the ''subalpine line'' up to 2,500 m and alpine meadows, also known as the ''alpine line'' above 2,500 m.
