How high can UV get in Geneva 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. June is the worst case: typical days average UV 6 (high), but the top 10% of days reach UV 9 (very 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 Geneva bad for travelers?

PM2.5 (fine-particle pollution) exceeds the WHO sensitive-group guideline (15 µg/m³) in 5 months: January, February, March, November, December. The worst month is February with a typical-day mean of 14 µg/m³ (moderate); on the worst 10% of days PM2.5 reaches 24 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.
