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

The worst month is February with a typical-day mean of 11 µg/m³ (moderate); on the worst 10% of days PM2.5 reaches 21 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.
