Climate
The Pirin Mountains and the
valley of the Mesta River belong to the Transitional Mediterranean
Climatic Area. In the Pirin Mountains themselves, the Mediterranean influences
change with the altitudinal belts, which outline three climatic sub-areas: •
The valley of the Mesta River - up to 1000 m above sea level •
Medium-height mountain sub-area - from 1000 to 2000 m
• High-mountain sub-area
- above 2000 m The varying relief forms influence the
temperature regime and the air humidity, the wind velocity and the amounts
of precipitation. The average wind velocity in the town's region
is about 0.8 m/sec, and the hollow character of the area predetermines the
very great number of windless days, which constitute averagely 72 % of the
days in a year. The average annual temperature is 11.3
°С, the average January temperature is -2 °С, and the average July
temperature is 19°С.
The average annual rainfall is between 620
and 780 mm, with a maximum in winter and a secondary maximum in autumn.
The month with
maximum rainfall is November, and the driest month is August. There are averagely
about 150 days per year that are suitable for agricultural work in the
open and
explorative tourism.
