Sunscreen for Tbilisi in December
Verdict
Optional
Bring a stick or travel-size — better than a sunburn on day one.
Why
Tbilisi in December averages highs of 48°F, lows of 34°F, 10 rainy days.
That climate makes sunscreen a judgment call. Bring a stick or travel-size — better than a sunburn on day one.
