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

The worst month is June with a typical-day mean of 17 µg/m³ (unhealthy for sensitive); on the worst 10% of days PM2.5 reaches 34 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.
