The lowlands have mild winters, averaging about 7 °C (45 °F). Summer temperatures average 24 °C (75 °F). In the southern lowlands, temperatures average about 5 °C (9 °F) higher throughout the year. The difference is greater than 5 °C (9 °F) during the summer and somewhat less during the winter.
Inland temperatures are affected more by differences in elevation than by latitude or any other factor. Low winter temperatures in the mountains are caused by the continental air mass that dominates the weather in Eastern Europe and the Balkans. Northerly and northeasterly winds blow much of the time. Average summer temperatures are lower than in the coastal areas and much lower at higher elevations, but daily fluctuations are greater. Daytime maximum temperatures in the interior basins and river valleys are very high, but the nights are almost always cool.
Average precipitation is heavy, a result of the convergence of the prevailing airflow from the Mediterranean Sea and the continental air mass. Because they usually meet at the point where the terrain rises, the heaviest rain falls in the central uplands. Vertical currents initiated when the Mediterranean air is uplifted also cause frequent thunderstorms. Many of these storms are accompanied by high local winds and torrential downpours.
When the continental air mass is weak, Mediterranean winds drop their moisture farther inland. When there is a dominant continental air mass, cold air spills onto the lowland areas, which occurs most frequently in the winter. Because the season's lower temperatures damage olive trees and citrus fruits, groves and orchards are restricted to sheltered places with southern and western exposures, even in areas with high average winter temperatures.
Lowland rainfall averages from 1,000 millimeters (39.4 in) to more than 1,500 millimeters (59.1 in) annually, with the higher levels in the north. Nearly 95% of the rain falls in the winter.
Rainfall in the upland mountain ranges is heavier. Adequate records are not available, and estimates vary widely, but annual averages are probably about 1,800 millimeters (70.9 in) and are as high as 2,550 millimeters (100.4 in) in some northern areas. The western Albanian Alps (valley of Boga) are among the wettest areas in Europe, receiving some 3,100 mm (122.0 in) of rain annually.The seasonal variation is not quite as great in the coastal area.
The higher inland mountains receive less precipitation than the intermediate uplands. Terrain differences cause wide local variations, but the seasonal distribution is the most consistent of any area.
In 2009 an expedition from University of Colorado, discovered four small glaciers in the 'Cursed' mountains in North Albania. The glaciers are at the relatively low level of 2,000 meters – almost unique for such a southerly latitude
Flora and fauna
Although a small country, Albania is distinguished for its rich biological diversity. The variation of geomorphology, climate and terrain create favorable conditions for a number of endemic and sub-endemic species with 27 endemic and 160 subendemic vascular plants present in the country. The total number of plants is over 3250 species, approximately 30% of the entire flora species found in Europe.
Over a third of the territory of Albania – about 10,000 square kilometers (2.5 million acres) – is forested and the country is very rich in flora. About 3,000 different species of plants grow in Albania, many of which are used for medicinal purposes. Phytogeographically, Albania belongs to the Boreal Kingdom and is shared between the Adriatic and East Mediterranean provinces of the Mediterranean Region and the Illyrian province of the Circumboreal Region. Coastal regions and lowlands have typical Mediterranean macchia vegetation, whereas oak forests and vegetation are found on higher altitudes. Vast forests of black pine, beech and fir are found on higher mountains and alpine grasslands grow at altitudes above 1800 meters
According to the World Wide Fund for Nature and Digital Map of European Ecological Regions by the European Environment Agency, the territory of Albania can be subdivided into three ecoregions: the Illyrian deciduous forests, Pindus Mountains mixed forests and Dinaric Alpine mixed forests. The forests are home to a wide range of mammals, including wolves, bears, wild boars and chamois. Lynx, wildcats, pine martens and polecats are rare, but survive in some parts of the country.

There are around 760 vertebrate species found so far in Albania. Among these there are over 350 bird species, 330 freshwater and marine fish and 80 mammal species. There are some 91 globally threatened species found within the country, among which the Dalmatian pelican, Pygmy cormorant, and the European sea sturgeon. Rocky coastal regions in the south provide good habitats for the endangered Mediterranean monk seal.
Some of the most significant bird species found in the country include the golden eagle – known as the national symbol of Albania – vulture species, capercaillie and numerous waterfowl. The Albanian forests still maintain significant communities of large mammals such as the brown bear, gray wolf, chamois and wild boar.The north and eastern mountains of the country are home to the last remaining Balkan Lynx – a critically endangered population of the Eurasian lynx
