September is, without qualification, the best month to visit Georgia. The summer heat breaks, tourist crowds thin significantly, accommodation prices drop 20–30% from August peaks, and the rtveli grape harvest begins in Kakheti — one of the most authentic and beautiful experiences in the Caucasus. Kazbegi turns golden with autumn foliage from late September.
Why September is the best month in Georgia
Three things converge in September to make it exceptional:
- Weather: Warm enough for outdoor activities (23–28°C in lowlands), cool enough to walk comfortably without August's oppressive heat. Zero risk of mountain snow until late October.
- Rtveli: The grape harvest in Kakheti is Georgia's most important cultural event. Villages come alive. Family wineries open their gates. You can participate — cut grapes, press them with your feet, drink new wine straight from the vat.
- Value: Hotels drop to post-summer prices while the experience is better than August in almost every respect.
Weather across all regions in September
| Region | Day temperature | Night temperature | Precipitation | Notes |
|---|---|---|---|---|
| Tbilisi | 23–26°C | 14–17°C | Low | Comfortable all month |
| Kakheti | 25–28°C | 13–16°C | Very low | Perfect for harvest |
| Kazbegi | 15–20°C | 5–10°C | Moderate | Foliage turns late September |
| Batumi | 22–25°C | 16–19°C | Moderate | Still warm enough to swim |
| Borjomi | 18–23°C | 10–14°C | Low | Park foliage begins |
Rtveli — participating in the grape harvest
Rtveli is the Georgian word for the annual grape harvest, which begins in Kakheti around the second or third week of September. It is the most important event in the Georgian agricultural calendar and one of the most accessible authentic experiences available to visitors.
What actually happens during a rtveli visit:
- You arrive at a family vineyard in the morning. The family has been working since sunrise.
- You are given a pair of scissors (satibo) and a basket. You cut grape clusters from the vines.
- The grapes are carried to the pressing area, tipped into a wooden trough (satsnakheli), and pressed — traditionally by barefoot treading, though modern families often use a mechanical press.
- The fresh grape juice (tsilikoni) flows from the trough into a buried clay vessel (qvevri) where it will ferment for months.
- Lunch is served at the family table: bread, vegetables, cheese, last year's wine from the qvevri, and an extraordinary amount of food.
- A bottle of homemade wine to take home: 10–20 GEL.
To participate, book a Kakheti tour with a guide who has village contacts. I run this tour specifically in September and early October — reach out via WhatsApp to check dates.
Top routes for September
Kakheti — the essential September destination
Kakheti wine country (2 hours east of Tbilisi) is mandatory in September. Beyond rtveli, the region has Sighnaghi (the "city of love" perched above the Alazani valley), Bodbe Monastery, Gremi fortress, and the David Gareja cave monastery complex on the semi-arid border with Azerbaijan.
Kazbegi — my personal recommendation for September
I prefer Kazbegi in September over any other month. Here is why: tourist buses are gone after the school year starts. The hiking trails are quiet. The light in early autumn is extraordinary — sharp and golden. And from late September, the deciduous trees on the mountain slopes begin turning, producing colours you cannot see in July or August. The Gergeti Trinity Church at 2,170 m with autumn foliage below it is one of the most beautiful sights in Georgia.
Tbilisi — comfortable all month
Tbilisi in September is the most pleasant version of the city. The 38°C August heat is gone. Evening temperatures make outdoor dining genuinely enjoyable. Rooftop bars fill up. The city's social life reaches its autumn peak.

We came to Georgia in September specifically for the harvest, and Timur arranged exactly what we were hoping for — a family vineyard near Telavi, three hours of cutting grapes, pressing with our feet, then the most generous lunch I have ever eaten. The grandmother brought out bottle after bottle of her wine from previous years and would not hear of us leaving. I speak no Georgian and she spoke no English but we communicated perfectly. Timur translated the important things and disappeared when translation was not needed. I have been travelling for twenty years and this was one of the most genuine afternoons of my life.
