Winter, from November to May, forms snow drifts of a couple of meters in height which are a particular challenge for winter sports lovers. This season is particularly interesting because of the landscape of the mountain under snow, which is somewhat like a white desert covered with rays of sunshine, above which there is nothing but the areal landscape.
The beauty of the mountain is augmented by the temper of its climate. It is the result of the geographical position of Bjelasnica within the Dinaric Mountains, its geological structure and altitude. The highest part of the Dinaric Mountains, 300 meters in length, towards the Adriatic Sea, represents a border of impact of two climates - Mediterranean and Continental. Air mass from the sea interferes with the air mass from mountains on Bjelasnica. That kind of interference results in rain and snow precipitation in autumn and great amounts of snow in the winter which is retains until late in the spring. This kind of climate specificity is suitable for developing winter sports.
A weather station was built on the highest part (2067 meters of altitude) in 1894. which is the highest constant inhabited point in Bosnia and Herzegovina. The peak itself was named after the Observatory. The mountain was named after the whiteness of its stones and snows which reside on its peaks up to August. An extraordinary mutability of weather characterizes the mountain so it is possible to experience three seasons in one day.
Winters are extremely sharp and long, spring weather is expected only after the first half of May and short summer weather is often followed by waves of cold air. The mean annual temperature is only 0.7°C because of the extremely low winter temperatures. The highest temperature is 24°C and the lowest is -41°C. Thick green grass covers the mountain in the summer while winters attract 4 meters of snow. Strong winds and thunders characterize the climate of this magnificent Bosnian mountain beauty.
