Regional context

In Las Vegas, NOAA NCEI 1991-2020 normals put January near 49°F and July near 92°F — a 43°F seasonal arc — with about 4 inches of precipitation over 10 rainy or snowy days.

Cool-season fronts carry Las Vegas's rain: February logs 0.8 inches on 1.7 days, against June's 0.0 inches on 0.0 — winter does the heavy lifting in Las Vegas. That cool-season-wet pattern aligns Las Vegas with places like Summerlin South, NV, Spring Valley, NV and Winchester, NV.

With a coldest-month mean of 47°F, Las Vegas stays mostly frost-free and grows year-round. The July peak near 92°F is Las Vegas's real limit, pushing cool-season vegetables to spring and fall. Within Las Vegas, low or inland lots lose 3-5°F overnight versus Las Vegas's coastal ground.
