June
#8 of 12 months
Strong option
Hot, sunny, and increasingly busy — the outdoor culture is at its peak but the heat is building.
- ↑The most sunshine of any month: 8.6 hours daily; Tbilisi in summer light, with the ochre and rose facades of the balconied houses, is the city at its most photogenic
- ↑Rainfall drops significantly to 58mm after the spring; June is drier than May and the risk of a ruined outdoor day is lower
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

June trade-offs
- ↓28°C average high with hot afternoons; midday sightseeing in the Old Town and up to Narikala becomes genuinely uncomfortable — early morning or evening exploration is significantly more pleasant
- ↓Tourist numbers are solidly at their summer peak; the more popular bars in Sololaki and the sulphur bath district get crowded on weekend evenings
- ↓Accommodation prices at moderate level — not expensive by European standards, but no longer the extraordinary value of the low season
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
