How high can UV get in Riga on the sunniest days?

September is the worst case: typical days average UV 3 (low), but the top 10% of days reach UV 4 (moderate) — and even higher. Months where the sunniest days routinely exceed the typical reading: April, September. Plan sun protection for the worst case, not the average.

The worst month is February with a typical-day mean of 15 µg/m³ (unhealthy for sensitive); on the worst 10% of days PM2.5 reaches 26 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.
