December
#9 of 12 months
Strong option
Cold and quiet with New Year approaching — the sulphur baths are at their best and prices are near their floor.
- ↑New Year is celebrated with real enthusiasm in Tbilisi; Rustaveli Avenue hosts outdoor celebrations and the Georgian New Year tradition (Alilo processions begin in the days before Christmas) gives December a distinctive festive character
- ↑The sulphur baths of Abanotubani are at their finest in December cold — the contrast between the frigid outside air and the 35–42°C mineral spring baths is exactly what they were designed for; private bathing rooms are available and affordable
September
#1 of 12 months
Best match
The grape harvest arrives — Rtveli season makes September the most culturally charged month in the Georgian year.
- ↑Rtveli (grape harvest) begins in Kakheti from mid-September; vineyard visits and harvest participation are available throughout the month — this is the most important event in Georgian agricultural and cultural life, 8,000 years in practice
- ↑Weather perfects itself: 26°C with 7.6 sunshine hours and minimal rainfall; everything the city offers is available without the July and August heat making outdoor activity uncomfortable

December trade-offs
- ↓Only 3.1 sunshine hours daily; December Tbilisi spends most of its time under grey skies, and the city's considerable visual beauty is substantially reduced without direct light
- ↓New Year's Eve pushes accommodation prices sharply upward in the Old Town and near Rustaveli Avenue; book ahead or choose the days either side of the 31st
- ↓Cold nights with temperatures near freezing; the old buildings of Sololaki and Abanotubani are not known for efficient heating, and some smaller guesthouses can be genuinely cold in the early morning
September trade-offs
- ↓Kakheti gets crowded during Rtveli and accommodation in the wine region must be booked well ahead for harvest weekends — day-tripping from Tbilisi is the pragmatic approach
- ↓September remains a popular travel month; visitor numbers are still moderately high, particularly around the harvest festival weekends
- ↓Nights become noticeably cooler from mid-September, requiring a layer for evening terrace dining
