Is May a Good Time to Visit Tbilisi?
May is a fair time to visit Tbilisi (5/10). With 11 daily sunshine hours and only 16 rain days, this month delivers genuinely reliable outdoor conditions, ranking it 3rd sunniest of the year in Tbilisi. Culture-focused travellers and those who prefer lighter crowds will find May a practical choice, with prices running lower than peak June without sacrificing all the good weather. June offers a similar profile at lower hotel rates if dates are flexible. Watch out for prolonged rain stretches: with 16 wet days, a fully outdoor itinerary is risky. Build in museum days and covered market visits as contingency. Planning tips: accommodation is generally available without long lead times, and flight prices are typically lower than peak season. Flexible travellers will find the best deals by booking 2-4 weeks ahead. Mid-week arrivals consistently unlock lower hotel rates than weekend check-ins.
May sits at a particular moment in Tbilisi's seasonal arc. Temperatures average 21°C during the day, placing this month in a comfortable middle band, noticeably warmer than the depths of winter but without midsummer extremes. Against the seasonal backdrop, 16 rainy days and 11 sunshine hours per day help calibrate expectations for what actually awaits on the ground.

What to Wear in Tbilisi in May
Packing for Tbilisi in May means dressing for 21°C days and 10°C evenings. A light cotton tee with a casual overshirt works well at 21°C, the overshirt doubles as a layer for air-conditioned venues. Evenings drop 11°C to around 10°C, a notable shift that catches underprepared visitors off guard. Pack a dedicated evening layer. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. With 16 rain days expected, a compact travel umbrella is worth the bag space. A waterproof jacket is better than an umbrella if you plan full-day outdoor routes. For temple and religious site visits, carry a lightweight scarf or sarong to cover shoulders and knees, required at most major sites across the region.
Local tip: Temple and religious site visits require covered shoulders and knees in most of Tbilisi's heritage areas. A lightweight scarf or sarong weighs almost nothing and solves the problem instantly.

Why is Tbilisi mild in May?
Tbilisi's May heat is driven by the Asian summer monsoon system, as the low-pressure cell that forms over the heated landmass draws warm, humid air from the oceans. The result is temperatures averaging 21°C with high moisture in the air. Overnight temperatures remain elevated at 10°C, as clouds and humidity prevent the earth from radiating heat away after sunset. Climate data: Open-Meteo ERA5 (1991–2020).
