Tbilisi’s climate is shaped by its position in the eastern part of Georgia, nestled in a valley at the foothills of the Lesser Caucasus. Summers (June–August) are hot and dry, with average highs of 30–32°C, but temperatures can exceed 35°C during heatwaves. July and August are the hottest months, and evenings offer some relief as temperatures drop. Rainfall is minimal in summer, and the city enjoys long daylight hours and up to 2,300 hours of sunshine annually. Occasional thunderstorms may occur, but most days are clear and sunny.
Winters (December–February) are moderately cold and relatively dry, with average highs of 5–8°C and lows near or just below freezing. Snowfall is possible but not frequent, and when it does occur, it’s usually light and short-lived. January is the coldest month, but Tbilisi’s winters are milder and sunnier than many European cities, with only 4–5 rainy days per month. Spring (March–May) and autumn (September–November) are the most pleasant seasons. Spring starts cool and wet, especially in March and April, but quickly warms up by May. Autumn is mild, with warm days and crisp nights, and is generally drier than spring. Both shoulder seasons are known for their vibrant foliage and comfortable weather, making them ideal for outdoor exploration. Winds are generally light to moderate year-round, and the city’s valley location helps shield it from the strongest gusts. Humidity is moderate, with summers occasionally feeling muggy, especially in July and August.
