How high can UV get in Košice 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.

Months where the sunniest days routinely exceed the typical reading: March, April, May, June, July, August, September. Plan sun protection for the worst case, not the average.

The worst month is December with a typical-day mean of 23 µg/m³ (unhealthy for sensitive); on the worst 10% of days PM2.5 reaches 36 µg/m³ (hazardous) 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.
