Las Vegas, Nevada frost dates
Frost is uncommon in Las Vegas. NOAA's 1991–2020 normals give a 50% chance of a 32°F freeze after January 20 and before December 15. In practice that means a freeze in roughly half of winters or fewer, usually on just a night or two, so dates are a poor guide here. Gardeners here plan around heat and the cool season, not frost.
Frost risk by date

Read the spring column like this: there is a 10% chance of a 32°F freeze after February 14. These are NOAA probabilities for the Las Vegas Mccarran Airport weather station (USW00023169, elevation 650 m), 1991–2020.
