Late spring and early summer.
May and June suit Tbilisi, Kakheti and western Georgia: the lowlands are green, and the heat has not yet built up. Higher valleys can still hold snow into June, so check trail conditions before planning a long walk from Stepantsminda or Mestia.
This is also a good time for canyons and caves around Kutaisi, before the busiest summer weeks.
High summer.
July and August are the main season for the Black Sea coast and for high mountain areas. The roads into remote valleys open for only part of the year: the Abano Pass into Tusheti is usually open from about the end of May to September and closed by snow for the rest of the year.
Lowland Georgia can be very hot in summer, with Imereti's highest temperatures reaching the high thirties. Plan city sightseeing for mornings and evenings, and use the mountains as a break from the heat.
Autumn and the harvest.
September and October are often the most rewarding months overall. The mountains are still open early in the season, the coast stays warm in September, and Kakheti celebrates the grape harvest, rtveli. Harvest dates vary by year and vineyard, so ask a producer about your dates rather than assuming a visit includes picking.
By late October, high passes and mountain trails become less reliable. Keep mountain days early in an autumn trip.
Winter.
Winter brings ski seasons in Gudauri, Bakuriani and Svaneti, and quieter, cheaper city breaks in Tbilisi and Kutaisi. The coast is mild but not a beach destination in winter, and some high roads close. See our Georgia in winter guide for what works and what to avoid.
