#1 of 12 months

Best match

April trade-offs

  • ↓April is Tbilisi's wettest spring month; 65mm with variable weather means days require flexibility — mornings often fine, afternoons potentially rainy
  • ↓Orthodox Easter week brings Georgian domestic visitors to Tbilisi in significant numbers; accommodation in Old Town fills up for the holy weekend
  • ↓Prices begin rising from the winter floor; April is still affordable but the rock-bottom winter rates are gone

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
