The town is at the middle latitude therefore the climate is a moderate-temperate-continental one also being influenced both by the eastern climate and the arctic (borealis) climate of north. As for the altitude, the place's landscape is part of the middle-high mountains specific climate. There are three main factors which determine this particular type of climate: cosmic factors (sun radiation), dynamic factors (general and regional circulation of atmosphere) and geographical factors (landscape and features of the active crust as well).
During summer, the general air circulation usually comes from the Atlantic ocean bringing up air and V&NV winds. The winds are alleviated by the night western mountains summits. The masses of the polar and Siberian air reach these places during winter as N, NV&NE winds. Masses of tropical air are quite seldom noticed here.
The annual global sun radiation never goes over 110 kcal/square cm. It is higher on the summits than in the valleys and has highest value during summer. The active crust (meaning a varied covered by forests and lawns), generates important local variations in the matter of values of the radiant balance. They can be noticed in air circulation and climate manifestations. The mixture between barren areas and slightly wooded areas generates contrast on a small area in the matter of the radiant aspect of the zone. This phenomenon usually place in winter, when everything is snowed in.
The climate has three main elements: air temperature, winds and rainfall.
The average annual temperature (AAT) oscillated between 6,80C in valley and 20C on peaks. The AAT is of 6,40C at Câmpulung Moldovenesc, 2,30C at Rarău and Giumalău. The highest temperature is recorded in July while the lowest one is recorded in January.
The average summer temperature (AST) reaches 16,50C at Câmpulung Moldovenesc, 6,80C and 11,80C at Rarău while the average winter temperature (AWT) reaches at -4,90C at Câmpulung Moldovenesc. It is to be noticed that Câmpulung Moldovenesc records higher temperature than other similar zones during winter because of him being a well sheltered depression.
The highest temperature ever to have been recorded in Câmpulung Moldovenesc was of 34,40C on 14th of August 1957 while the lowest was of 30,20C on 5th of February 1956. The average number of frost days in of 150 days per year and the one average positive temperature is of 220 days. There are only around 5 days of tropical temperature (over 300C) per year. Also, to be noticed that are the seldom thermal inversions meaning that the temperature in Câmpulung Moldovenesc is lower than the one on the peaks of Rarău.
The nebula has a 6 to 7th value. The stratificate clouds dominate the winter when the peaks of the mountains stay above the clouds generating the so-called "sea of clouds" over the valleys. As for the summer, cumulus and cumulonimbus are the most frequent clouds. They generate cloud-bursts and heavy rains. There are 80-90 cloudless days per year.
There is an average of 688,2 mm/year in Câmpulung Moldovenesc and 830 mm/year on Rarău mountain. The maximum amount of precipitation is recorded in June (like 140,7 mm in June 1937), while the minimum one is recorded in October (2,5 mm in October 1961).
The snow falls usually from October (or peaks but in November in valleys) to April. It forms snowdrifts last long (on the summits they last till summer). There fore winter sports are at home here. Snow represents 20-40% of the annual precipitations. The snow layer has an average thickness of 20-30 cm and lasts over 100 days. Short yet gusty hail may fall during summer because of the rapid convection of the clouds.
The prevailing and the most frequent winds all along the year are those heading NV-SE. They are not usually speedy nor does they come in gales. Therefore the blizzards are rarely to be felt during winter. On the peaks thought, the blizzard may "build" snowdrifts of 1-2 m high which do not melt till summer. This also explains why on the southern side of the mountains the winter is 14 days shorter.
Here the air is highly fresher than in most of other areas in the country because of the lack pollution industry on one hand and the natural purification made by conifers forests, on the other hand.
The waters network:
Although the underground waters existing in the area of Obicini, Rarău and Giumalău mountains, have not not been mapped yet, they confirm their being there though a very large number of springs.
They can be found from the foot of the mountain to the ridge of Rarău. More precisely, the underground waters are stored into dejection cons, in terraces foundation and in meadows. The thickness of the water layers vary depending on precipitation and rock's permeability. Both lime stones and the dolerites allow underground lake age and thus the water collects into limy voids, fissures and rents. The flow of the springs show the extent to which underground waters are influenced by the precipitation. However, the lands are quite well afforested and the trees stop the water to overflow. The lowlands are sometime marshy. The springs water is drunk as it naturally is because it is of a very high quality, in no way polluted.
The major part of the surface waters are running waters, lakes being very seldom to be found (like the only mountain lake in Sadova village and other few unimportant man-made lakes). The rectangular basins of Obcini and Rarău-Giumalău have a high density and they are formed by cutting the tributaries in right angles according to the main collector. The rivers have always been very important in native peoples lives. Along them they built roads and railways which determine the form and the dimension of the localities. Every little community in Obcini stand nowhere else but on the valleys or the terraces cut by waters. The waters crucially contributed to the cutting of the relief as well.
The Moldova river is the main collector of the waters in the area. It springs from Lucina (Aluniş summit - 1295 m), it separates Obcina Feredeului from Obcina Mestecănişului and collects many tributaries along its flowing: Lucina, Lucava, Tătarca, Răchitiş, Botuş, Deulţ, Delniţa, Colacu, Arseneasa, Valea Putnei, Mesteăcanu, Valea Seacă, Valea Caselor, Şandru, Suha on its right, and Suliţa, Benia, Breaza, Pârâul Negru, Moroşanu, Timen, Pârâul Cailor, Sadova, Pârâul Morii, Corlăţeni, Deia, Hurghiş, Moldoviţa, Dobra, Belţagu, Tocila, Cetăţuia and Humor on its left.
Upstream Moldova river has a slope of 12 m/km and a flow of 4,55 mc in Câmpulung Moldovenesc, 5,94 mc in Prisaca Dornei, 10,5 mc in Vama after its juncture with Moldoviţa. In the area there are also tributaries of the river Bistriţa, to the west (Cârlibaba and Ţibău) and of the Suceava river on the east. The chemical composition of the Moldova river is mainly made by bicarbonate (considered to be of 1st quality upstream). Moldoviţa contains more sulphate. Consequently the surface waters are unpolluted and almost as clear as the underground waters are.
