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

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 March with a typical-day mean of 13 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.
