North Las Vegas spans USDA zones 8 to 9 across its ZIP codes (Zone 8b, Zone 9a); the city center sits in Zone 9a, so warmer and cooler pockets exist either side of that.

These are 50%-probability averages modeled from North Las Vegas's USDA hardiness zone and regional climate normals — not a single-station reading. In a typical year the last spring frost will have passed by March 8, but a colder-than-average year can run 1-2 weeks later. Plant tender crops (tomatoes, peppers, basil) once both soil and night temperatures are consistently warm — a thermometer beats the calendar.

Local microclimate notes

Zone tables give you the average — but North Las Vegasgardens vary. South-facing walls and paved areas can run a full half-zone warmer than the published rating. Low-lying spots, frost pockets, and shaded north sides can run colder. If you've gardened here a few seasons, your own frost record — the last time you actually got frost damage — beats any national average.

Source and methodology

Hardiness zone from the USDA Plant Hardiness Zone Map (2023 revision). Frost-date and growing-season figures are modeled from North Las Vegas's USDA hardiness zone and regional NOAA 1991-2020 climate normals — zone-level estimates, not a per-station record, so treat them as planning guidance and confirm against your own local frost history. Crop recommendations draw on US Cooperative Extension references, curated by the Growli editorial team. Last reviewed June 2026.
