Traveller notes on Mestia in September
Mestia's forum warns that September is when the mountain weather starts turning genuinely wetter, with regulars recommending a night in Kutaisi or Zugdidi to break up the drive rather than pushing straight through in poor conditions. It won't be cold, but rain coats are standard advice, since bad weather in the mountains can roll in on short notice.
