How high can UV get in Vienna 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. July is the worst case: typical days average UV 6 (high), but the top 10% of days reach UV 8 (high) — and even higher. Months where the sunniest days routinely exceed the typical reading: March, April, May, June, July, August, September, October. Plan sun protection for the worst case, not the average.
Is air quality in Vienna bad for travelers?
PM2.5 (fine-particle pollution) exceeds the WHO sensitive-group guideline (15 µg/m³) in 6 months: January, February, March, October, November, December. The worst month is December with a typical-day mean of 19 µg/m³ (unhealthy for sensitive); on the worst 10% of days PM2.5 reaches 32 µg/m³ (unhealthy) 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.
