How high can UV get in Tartu on the sunniest days?
Most days look like the monthly average, but on the sunniest ~1 in 10 days UV climbs higher than the mean suggests. September is the worst case: typical days average UV 2 (low), but the top 10% of days reach UV 3 (moderate) — and even higher. Months where the sunniest days routinely exceed the typical reading: April, September. Plan sun protection for the worst case, not the average.
Is air quality in Tartu bad for travelers?
PM2.5 (fine-particle pollution) exceeds the WHO sensitive-group guideline (15 µg/m³) in 2 months: February, December. The worst month is February with a typical-day mean of 10 µg/m³ (fair); on the worst 10% of days PM2.5 reaches 16 µg/m³ (unhealthy for sensitive) and higher. People with asthma, heart conditions, or sensitive children may want to avoid these months or limit outdoor activity. Source: CAMS via Open-Meteo.
