Portland weather, explained by a local pattern
Portland shares Seattle's rhythm — steady gray drizzle from fall through spring, then a dry, golden summer from July through September that locals plan their whole year around. Summer rain is genuinely rare. The forecast anxiety here is really about the other nine months, when the question isn't if it will drizzle but whether it will briefly stop.
How to use this page
The verdict above reads the next 12 hours of official National Weather Service hourly data for central Portland 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?
