How much rain did I get?
Enter a ZIP code or a city, or share your location, to see how much rain fell there in the last 24 hours. The number comes from NOAA’s Multi-Radar Multi-Sensor system: weather radar corrected against the national rain-gauge network, for the ~1 km grid cell your spot sits in.
Looking for a city instead? Rainfall totals by city show the last 24 hours next to each city’s 30-year monthly averages.
Common questions
How accurate is a rainfall total from radar?
It is an estimate for a ~1 km cell, not a gauge reading. NOAA's MRMS combines radar with rain gauges, and in most places the gauge-corrected figure lands close to what a well-sited gauge catches, but rain varies inside a single kilometre and a gauge under-catches in wind. Raindex does not publish an accuracy percentage, because this data cannot honestly support one.
Why is the last hour or two missing?
The gauge-corrected pass that this lookup reads runs about 97 minutes behind real time. The 24 hours shown end at the newest hour NOAA has published, and the time is stated with the total.
Does this work outside the United States?
No. MRMS covers the lower 48 United States. Alaska, Hawaii and anywhere outside the grid return no reading rather than a number for somewhere else.
Can I see more than 24 hours, or a history?
In the Raindex app: every saved place keeps a day-by-day record from the day you save it (the last 7 days filled in on the free plan, 30 on a paid one), and paid plans add 3 to 72-hour windows.
Do you store my ZIP code or location?
Raindex does not keep either. A shared location is rounded to about 1 km in your browser before it is sent, the ZIP or rounded position is used once to fetch the reading, and neither is sent to analytics. Like any website, our host may keep short-lived request logs.
Where these numbers come from
- What Raindex measures
- Raindex measures observed rainfall from NOAA’s Multi-Radar Multi-Sensor system (MRMS) at roughly 1 km resolution, combining radar estimates with rain-gauge adjustment. The gauge-corrected pass runs about 97 minutes behind real time, so a recent total can be revised upward or downward as gauge data arrives.
- What neither one can tell you
- A 30-year average says nothing about this week. A radar estimate is still an estimate: it can disagree with the gauge in your yard because of terrain, the height of the radar beam over your property, how rainfall varies within a single kilometre, and the fact that a gauge itself under-catches in wind. Raindex labels each reading gauge-adjusted, radar only or provisional so you can see which you are looking at. It does not publish an accuracy percentage, because that is not a number this data can honestly support.
