Denver weather, explained by a local pattern
Denver's weather changes by the hour, not the day: brilliant mornings breed mountain-built thunderstorms that roll over the city on summer afternoons, and spring can deliver 70°F sunshine and a foot of snow in the same week. The local rule for summer hiking and patios alike — do it before 2pm, when the lightning shows up.
How to use this page
The verdict above reads the next 12 hours of official National Weather Service hourly data for central Denver 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?
