Search-interest seasonality (Google Trends 2021-2025) is lowest in January and peaks in November. Interest tracks both in-trip visitors and lead-time planners, so treat it as a "destination is on people's minds" signal rather than literal arrivals.

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

Months where the sunniest days routinely exceed the typical reading: March, April, May, June, July, August, September, October. 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 7 months: January, February, March, April, October, November, December. The worst month is February with a typical-day mean of 25 µg/m³ (unhealthy); 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.
