Check the UV index with Siri
Quick answer
"What's the UV index today" and Siri reads the current UV level for your location and what it means for sun exposure. Ask about another place — "UV index in Phoenix" — when you're planning a trip. Pulled from the Weather app, so open it for the hourly curve.
Say this
“What's the UV index today”
How it works

Did this work for you?
Be the first to confirm this.
If Siri doesn't get it
UV data needs Location Services for Weather or a named city, plus internet. For the hourly breakdown, open the Weather app directly.
