Las Vegas weather, explained by a local pattern
Las Vegas is one of America's driest cities, but its rare rain makes headlines: summer monsoon surges can flood washes and casino parking garages in a single hour. Summer heat routinely tops 110°F, making timing — not precipitation — the planning question. Winter is mild and reliably dry, prime patio season.
How to use this page
The verdict above reads the next 12 hours of official National Weather Service hourly data for central Las Vegas and reduces it to one answer. The bar chart underneath shows the precipitation probability hour by hour — taller and bluer means wetter. A quick reading guide: probabilities under 25% are generally safe to plan through, 40% and above during your specific window deserves a plan B, and any active NWS alert (which appears automatically above the chart) outranks everything else on this page.
Conditions can differ across the metro, so for your exact neighborhood — and to check a specific date and time instead of right now — use the ZIP code checker, which also finds your longest dry window of the day. For a deeper read on what these percentages actually mean, see our guide: What does a 40% chance of rain actually mean?
