Understanding Rain Probability
What the percentages mean
- 0-20% — Very unlikely. Leave the umbrella at home.
- 20-40% — Slight chance. An umbrella is optional.
- 40-60% — Good chance. Bring an umbrella.
- 60-100% — Rain is likely. Plan for wet conditions.
How we estimate rain timing
We analyze hourly precipitation data from the National Weather Service. When consecutive hours show above 40% probability, we identify that as the rain window and show you estimated start and end times.

Frequently Asked Questions
How do I know if it will rain tomorrow?
Check the hourly precipitation probability for your city. A chance above 40% means rain is likely. We show you the exact hours when rain is expected, so you can plan around it.
What does a 60% chance of rain mean?
A 60% chance of rain means that, given current atmospheric conditions, there is a 60 in 100 probability of measurable precipitation at your location. It doesn't mean it will rain for 60% of the day.
Is morning or afternoon rain more common?
It depends on your location and season. Coastal areas often see morning clouds, while inland areas tend to have afternoon thunderstorms (especially in summer). Check your local hourly forecast for the most accurate timing.
