Sunshine!
Even if you travel outside the tourist season, which begins in spring and ends in October, you'll enjoy a temperate climate, mostly sunny. In short, a humid trend comes from the Black Sea and an arid trend from the Caspian Sea. In the Greater Caucasus, a region of atmospheric turbulence between maritime and continental influences, the high mountain peaks form a natural shield protecting Georgia from air masses coming from the icy plains of Russia. The Lesser Caucasus, meanwhile, protects against the heat of the southern desert climate, moderating heat and humidity. Microclimates also play their part, varying according to the inclination of the mountain slopes.
In Western Georgia
Thanks to its proximity to the Black Sea, the western coastal plain, Colchis, has a subtropical climate of the humid Mediterranean type. Rainfall is fairly abundant on the coast (1 500 mm of annual rainfall on average, 2 500 mm in Batoumi), particularly in autumn. In this zone, the climate remains mild, even in winter. That said, the icy air masses of Russia are not far away: even if the Caucasus is a screen, some of them can deceive the enemy! Thus, one can have cold air, even snow. Generally, the temperature in winter varies between 4 and 7 °C, rarely below. Summer is hot - even very hot - and very humid, with an average of 23°C. It lasts until October. In Adjaria, the climate is almost subtropical, the seasons are not very marked. The weather changes there very quickly and constantly! Batumi is the city in Georgia with the most rainfall and the most sunshine per year. Such a climate is a paradise of lush vegetation and favours the cultivation of tea.
In East Georgia
Generally, at low altitudes, summers are very hot and dry, winters colder and drier than in the West, but still temperate. The shoulder seasons are longer, with April and October being particularly rainy.
Kakhetia, a land of vineyards, is surrounded by mountains. Marked by a continental influence, its summers are hot and dry, with plenty of sunshine. The border area with Azerbaijan is characterized by an almost desert-like climate, with sparse vegetation.
Tbilisi
The capital enjoys a "Mediterranean" climate, but much drier than on the coast. The average annual temperature is around 13°C (compared with 12°C in Paris). In winter, the lowest temperature is between 1 and 3°C, rising to 25°C in summer. Annual rainfall is 500 mm, with a minimum in winter and a maximum in spring. In winter, snowfalls can be frequent, but given the low level of precipitation, they are not very abundant. Tbilisi is also subject to very strong winds. Springs are hot and rainy, especially in April, as is autumn. The autumn season lasts until December.
In the Little Caucasus
In terms of humidity, the facades facing the Black Sea contrast with the subtropical slopes of Guria and Adjaria.
The Tori, Bordjomi and Bakouriani regions and western Meskethia enjoy a temperate, healthy alpine climate, ideal for spa resorts. Akhaltsikhé, on the other hand, is cut off from the humid winds and has a dry, semi-continental climate, with very hot summers and cold winters. Vegetation is Mediterranean. The terraces of Djavakhetia and western Kvemo-Kartlie are subject to very cold winters, due to their altitude and arid continental influences. Temperatures can drop to -30°C.
The Great Caucasus
This mountainous area is defined by a classic alpine climate, more or less pronounced depending on altitude, distance from the Black Sea and position in relation to the Caspian Sea. In the valleys, a foehn-type wind can blow.
