Best time to visit Tskaltubo
The best time to visit Tskaltubo is May, September or early October. Days are warm, between 22 and 27 °C, and the sticky heat of midsummer has either not arrived or has faded, so walking around the spa park and the nearby canyons is comfortable. June to August suit visitors pairing the baths with cave tours who do not mind 30 °C afternoons. The baths usually run all year, so a winter stay works if you accept grey, wet days.
Tskaltubo weather by month shows one clear difference from Kutaisi, only about 10 km away: more rain. The spa town gets roughly 1,690 mm a year against 1,360 mm, and its peak comes in December rather than October. Paths through the spa park and around the abandoned sanatoriums turn muddy and slippery after rain, so wear shoes with grip and save the baths for a downpour.
What to pack for Tskaltubo
- Light layer for the cool air inside Prometheus Cave
- Umbrella for winter, when December brings about 193 mm
- Breathable clothes for humid 30 °C August days
- Shoes with grip for muddy spa-park paths
- Light rain jacket for spring at Okatse Canyon
Tskaltubo weather: FAQ
Is Tskaltubo hotter than Kutaisi?
Only slightly. August highs average about 30.5 °C (87 °F) in Tskaltubo against 30 °C (86 °F) in Kutaisi, and January days are nearly the same, around 10 °C (50 °F). The real difference is rain: Tskaltubo gets roughly 1,690 mm a year, Kutaisi about 1,360 mm.
Is Tskaltubo worth visiting in winter?
Yes, if the baths are the reason for your trip. Winter days reach about 10 to 12 °C (50 to 54 °F) and frost is uncommon, but December is the wettest month, about 193 mm, and cloud covers roughly half the sky. Prometheus Cave and the spa make good rainy-day plans; the canyon walkways are less inviting.
When is the best month for Okatse Canyon and Kinchkha Waterfall?
May and September to early October work best, with highs around 22 to 27 °C (72 to 81 °F) and fewer rainy days than in winter. Kinchkha Waterfall is usually fullest in spring. Both sit higher than Tskaltubo, so the air there feels a little fresher.
How much does it rain in Tskaltubo?
A lot: wet weather in Tskaltubo is the rule rather than the exception, with some 1,690 mm falling over roughly 133 days of at least 1 mm. December is the wettest month, around 193 mm, and May the driest, about 91 mm. Even in summer it rains on about 11 days a month, so keep an umbrella in your bag.
