Phoenix weather, explained by a local pattern
Phoenix is dry roughly 300 days a year, but the exceptions are theatrical: July through September the monsoon brings late-afternoon walls of dust and lightning that arrive fast and leave faster. Summer heat above 110°F is its own weather event — morning is the only sane window for anything outdoors from June through September.
How to use this page
The verdict above reads the next 12 hours of official National Weather Service hourly data for central Phoenix 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?
