Division

The mountain range is divided into four distinct parts. East Rila, known also as Musala Rila, is the largest and highest subdivision, situated between the valleys of the rivers Beli Iskar and Belishka. It is formed of two main ridges. The Musala Ridge spans in north–south direction between the valleys of Beli Iskar and Maritsa; the Ibar Ridge runs in west–east direction from the summit of Marishki Chal to the Avramovo Saddle. It covers 37% of the mountain's territory and contains the highest summit in the range —

It stretches between the valleys of the rivers Beli Iskar, Cherni Iskar, Levi Iskar, Iliyna and Rilska. The later divides the two main ridges in Central Rila, Skakavitsa and Rilets. The highest summit is Cherna Polyana (2,716 m); other important peaks are Skalata, Small and Big Skakavets, Rilets; there are 28 peaks over 2,100 m. This subdivision is renowned mainly for the glacial lakes Ribni, Dzhendemski, Manastirski, as well as the largest glacial lake in the Balkan Peninsula —

Northwest Rila, known also as Malyovitsa Rila, occupies about 24% of Rila and is situated between the valleys of Rilska to the south, Levi Iskar to the east, Samokov to the north-east and Dupnitsa to the west. Its much lower northern section is called Lakatitska Rila. It is linked with the Verila mountain range to the north through the Klisura Saddle, and with Central Rila to the east through the Kobilino Branishte saddle. The average elevation is 1,556 m; the highest summit is Mount Golyiam Kupen at an elevation of 2731 m. There are 29 peaks over 2,100 m. This subdivision is known for its rugged peaks and picturesque lakes in the Alpine zone that include the

and Siberian anticyclones in summer and winter, bringing droughts. The local microclimate is also influenced by the terrain, the exposure of the slopes and the orientation of the valleys. The average temperature decreases and the average precipitation increases with elevation. The coldest month is March and the hottest one August. Negative temperatures remain on average for about nine months in the Alpine zone, often continuing until the end of June. A steady rise in temperature is observed in the middle and end of July. Even during the summer months, temperature over 10 °C do not hold up for long periods. About five to ten days in June, July and August have an average temperature above 15 °C. This determines the short vegetation period in the high elevation areas which varies from three to six months; it lasts about three months at elevation over 2,000 m. The average annual temperature is 2.6 °C on the northern slopes and 3.1 °C on the southern. With an average annual temperature of −3.0 °C, Musala is the coldest place in Bulgaria. The lowest absolute temperature in Rila was also measured there: −31.2 °C; the lowest mean monthly temperature was recorded there in February: −11.6 °C. The absolute maximum temperature at Musala is 18.7 °C. Temperature amplitude decreases with elevation from 20 °C at 800 m to 15 °C at 2,800 m. Temperature inversions, i.e. increase in temperature with height, are frequent on the northern slopes and occur especially often in the Samokov Valley, Borovets and Musala, where it is observed in 250 days annually. The annual precipitation varies with elevation and slope orientation. The annual precipitation is 653 mm at

(1,029 m), 932 mm at Borovets (1,350 m) and 1200 mm at Musala (2,925 m); about 80% of it being snow at the later. The rainfall occurs mostly in summer and spring on the northern slopes, with maximum in June and minimum in February; the rainfall increases in winter and decreases in summer on the southern slopes and yet the monthly maximum and minimum are the same; there are 130–160 days with rainfall/snowfall. Air humidity in the highlands of Rila ranges between 80 and 85%. The coldest winter months are also the driest. Humidity differs on the northern and southern slopes of Rila. The snow cover above 1,000 m begins to form on 10–15 December on the northern slopes and after 20–30 December on the southern. Its average monthly thickness reaches 20 to 30 cm in February at low elevations. In the Alpine zone above 2,000 m the snow cover is thickest in March, reaching 70 to 80 cm. In the highest ridges the maximum thickness reaches 200 to 240 cm. The snow cover remains for an average of 70–80 days at elevations of 1,200–1,300 m and 180 to 200 days at elevations above 2,000 m.

s are frequent, often caused by temperature changes by the influx of warm Mediterranean air masses. Winds may reach speed of 40–45 m/s (over 100 km/h) at the summits, with mostly south-western and western orientation. The north-west and north-east winds are more moderate. The average monthly wind speed on the highest mountain summits reaches 11–12 m/s. In the lower parts, the average monthly speed varies from 1.2 to 2.5 m/s and in the middle height zone it ranges from 2.5 to 3.2 m/s. Winds are usually strongest in winter and lightest in autumn. The annual duration of sunshine in the Alpine zone is 1930 hours with maximum in August and minimum in December–January; it raises to more than 2150 hours at 1,000 m.

The runoff comes from snowmelt in the Alpine zones and rainfall. Water discharge reaches its maximum in late spring and early summer with spring accounting for more than half of the total annual discharge. The maximum at the highest elevations is in summer due to the late snowmelt. The minimum is in autumn and winter. The largest waterfalls are Skakavitsa (70 m) and Goritsa (39 m). There are abundant

The cirques at the high elevation zone contain 189 glacial lakes; there are also about 30 smaller ones that evaporate in summer, including tectonic lakes like Panichishte. Their location is closely linked to the snowline during the last glacial period and most of them lie at elevations between 2,100 m and 2,500 m. Most lakes (28) are situated at elevations between 2,300 m and 2,350 m; there are 23 between 2,350 m and 2,400 m, 19 between 2,250 m and 2,300 m and 19 between 2,400 m and 2,450 m.

Most of them are between 2 m and 10 m deep and four reach depth of over 20 m. The water is transparent as deep as 15 m. Most of the lakes are covered with ice during most of the year — from October to June. The ice thickness reaches 3 m in the highest lakes.
