How to Find Hail and Wind History at an Address: 2026 Property Weather Guide
When someone asks whether a property experienced hail or strong wind on a particular date, the answer is rarely sitting in one perfect database.
Historical weather research is usually a process of comparing several kinds of evidence: hail maps, wind maps, radar-derived estimates, nearby weather-station observations, storm reports, warnings, and official historical records.
Each source answers a slightly different question.
For a homeowner, roofer, public adjuster, insurance professional, attorney, researcher, or property manager, understanding those differences is often more useful than simply finding the largest number on a weather map.
This guide explains how to research hail history and wind history at a specific address, what data to look for, and how to interpret it without overstating what the records actually show.
Start With the Address, Not Just the City
Weather varies over surprisingly short distances.
A thunderstorm may produce large hail in one neighborhood and little or none several miles away. A downburst may generate a strong wind gust near one observing station while another station nearby records substantially weaker conditions.
That is why a search such as “hail in Dallas on May 20” and an address-level hail lookup are not necessarily answering the same question.
A useful property-weather investigation starts with three basic pieces of information:
- The exact property location
- The date or range of possible storm dates
- The type of weather being researched
If the date is unknown, the first step may instead be identifying candidate storm dates before examining individual events.
StormAuditor's Address Lookup is designed around this property-first approach.
How to Find Hail History at an Address
There is no nationwide network of instruments measuring hailstone diameter at every house. Historical hail research therefore depends on several complementary sources.
1. Look at the broader hail pattern
A historical hail map or hail swath can help identify storms that crossed the surrounding area.
Radar is particularly valuable for this purpose because it provides spatial coverage between individual ground reports.
NOAA's Multi-Radar/Multi-Sensor system produces the Maximum Estimated Size of Hail product, commonly called MESH. MESH uses radar-derived information to estimate hail size associated with a storm. NOAA describes MESH as an estimated hail-size product rather than a measurement of hailstones at individual properties.
That distinction matters.
If a radar product estimates 1.5-inch hail near an address, the appropriate conclusion is that radar analysis indicated hail-producing conditions in that area. It does not mean someone measured a 1.5-inch hailstone on that roof.
StormAuditor's Hail Map can be used to explore the broader geographic pattern before narrowing the research to an address.
2. Check nearby hail reports
Ground reports provide another type of evidence.
National Weather Service Local Storm Reports can document hail size, damaging wind, measured gusts, tornadoes, flooding, and other significant weather observations. Reports may originate from trained spotters, emergency managers, law enforcement, the public, media, or other sources.
A hail report may include:
- A measured hail diameter
- An estimated hail size
- An object comparison
- A reporting location
- A report time
- Information about who submitted the observation
Distance is important.
A measured 1.75-inch hail report two miles from a property is useful evidence that large hail occurred nearby. It is still a report from two miles away—not a measurement made at the property itself.
That is why good historical research preserves both the magnitude and the distance from the address.
3. Compare radar and ground reports
Radar estimates and ground observations work best when they are not treated as interchangeable.
Radar can help answer:
Where did the hail-producing portion of the storm appear to travel?
A ground report can help answer:
What hail was actually observed at this particular reporting location?
When both sources point toward similar conditions in the same area and time period, the event becomes easier to understand.
When they disagree, that disagreement is useful information too.
Hail can vary significantly across a storm, and no single source should automatically override all others.
How to Find Wind History at an Address
Historical wind research presents a different problem.
Unlike hail, wind is measured continuously at many official observing stations. But those stations are still separated by miles, leaving large areas without a direct instrument measurement.
A useful wind investigation therefore combines measurements with information about the surrounding wind field.
1. Find nearby measured wind gusts
Official ASOS and AWOS weather stations are particularly useful because they can provide direct instrument observations.
Suppose a station four miles from a property recorded a peak gust of 61 mph.
The strongest factual statement is:
A weather station approximately four miles from the property recorded a 61 mph gust.
That is different from saying:
The property experienced a 61 mph gust.
The first statement describes an actual measurement and its location. The second attempts to transfer that measurement to another location.
Exposure, terrain, storm structure, vegetation, buildings, distance, and the localized nature of thunderstorm winds can all affect how representative a nearby station may be.
2. Examine the broader wind field
Because weather stations do not exist at every address, meteorologists also use gridded analyses and numerical weather information to describe conditions between observing locations.
StormAuditor's wind methodology incorporates public meteorological datasets to estimate peak wind conditions at an address while retaining nearby observations as supporting context. The methodology and validation information are published for users who want to examine how those estimates are produced.
You can review the StormAuditor Wind Methodology for the technical details.
An estimated wind value should still be identified as an estimate rather than presented as an instrument reading from the property.
3. Review wind-related storm reports
Local Storm Reports can provide valuable additional context for convective wind events.
Reports might describe:
- Measured wind gusts
- Estimated wind speeds
- Trees or large limbs down
- Power-line impacts
- Structural observations
- Thunderstorm wind damage
These records can help reveal localized impacts that may not have occurred directly at an official weather station.
However, an estimated wind report and a measured wind gust are different types of evidence and should remain labeled accordingly.
Hail Maps and Wind Maps Are Starting Points
Maps are extremely useful because they make storm geography easier to understand.
They can quickly show:
- Where stronger conditions were estimated
- How a storm moved through an area
- Where reports were concentrated
- Which communities were near the event
- Whether an address was near or within a mapped swath
But a colored polygon should not be interpreted as a perfect boundary.
Weather does not suddenly change because a property sits one pixel outside a contour.
Hail size, wind speed, and storm impacts can change continuously across space, while the map itself is a simplified representation of the underlying data.
That makes maps excellent discovery tools, but they should generally be followed by closer examination of the records around the address.

What If You Don't Know the Storm Date?
This is one of the most common historical-weather research problems.
A property owner may remember a major storm “sometime last spring.” A contractor may encounter conditions that warrant reviewing previous severe-weather activity. An adjuster or researcher may inherit a file without a clearly established event date.
Rather than guessing, work backward from the historical record.
Search candidate dates
Look for dates when the surrounding area experienced:
- Significant hail activity
- Strong thunderstorm wind
- Nearby measured gusts
- Severe-weather reports
- Relevant NWS warnings
- Major regional storm systems
StormAuditor's Date-of-Loss Database organizes severe-weather dates using public NOAA and NWS records and can be filtered by location, time period, and hazard.
A candidate date is still a research lead, not proof that a particular property experienced damage on that date.
Once promising dates are identified, each event can be researched at the address level.
Don't Confuse a Warning With an Observation
Warnings are one of the easiest weather records to misinterpret.
A Severe Thunderstorm Warning tells you that severe weather was occurring or expected within a warned area.
It does not establish that every property inside the polygon experienced the maximum listed hail or wind threat.
For example, a warning may reference 70 mph wind and 1.5-inch hail while the strongest part of the storm travels through only a portion of the polygon.
Warnings are valuable for:
- Timing
- Storm movement
- Geographic context
- Threat information
- Understanding what forecasters knew during the event
They simply need to remain labeled as warnings, rather than measurements.
Official Historical Storm Records Are Useful—But They Arrive Later
NOAA's National Centers for Environmental Information maintains the Storm Events Database, which contains significant weather-event records collected by the National Weather Service.
These records are extremely useful when researching older storms.
They are less useful as the sole source for very recent events because the historical database is not updated in real time. NCEI explains that Storm Events data generally move through an NWS submission and processing cycle before appearing in the archive.
For recent storms, researchers may therefore rely more heavily on near-real-time reports, observations, warnings, radar products, and other weather records until the later historical entries become available.
Why Two Weather Sources May Disagree
Finding different values from different weather tools does not automatically mean one source is wrong.
They may be measuring or estimating entirely different things.
Consider these hypothetical records from the same storm:
- Radar estimates hail near 1.4 inches over an area
- A spotter reports measured 1.0-inch hail three miles away
- Another report lists estimated 1.75-inch hail six miles away
- A severe thunderstorm warning references the possibility of 2-inch hail
Those four numbers do not describe the same observation.
Likewise, for wind:
- An airport measures a 54 mph gust
- A storm report estimates 65 mph wind elsewhere
- A gridded analysis estimates 48 mph near the property
- A warning references 70 mph gusts
The purpose of research is not necessarily to select the biggest value.
It is to understand what each value represents, where it came from, when it occurred, and how close it was to the property being researched.
A Better Workflow for Address-Level Storm Research
For most properties, a practical investigation can follow this order:
Step 1: Identify possible storm dates
Search historical activity for the city, county, or state.
Step 2: Open the hail or wind map
Determine whether the broader storm crossed the vicinity.
Step 3: Center the research on the address
Review weather records geographically relevant to the property.
Step 4: Check direct observations
Look for nearby hail reports, measured wind gusts, and other ground observations.
Step 5: Review radar or gridded estimates
Use spatial datasets to better understand conditions between direct observations.
Step 6: Check warnings and event records
Use these records for timing, storm context, and corroboration.
Step 7: Keep measurements and estimates separate
Do not describe radar estimates, modeled values, warning threats, and station measurements as if they were the same thing.
Step 8: Preserve uncertainty
Weather evidence can describe the storm environment surrounding a property. It cannot, by itself, determine whether a particular building component sustained damage.
How StormAuditor Organizes the Research
Public weather data in the United States is extensive, but it is distributed across numerous systems.
StormAuditor is designed to bring relevant portions of that record into a more practical property-research workflow.
Depending on the tool and event, StormAuditor incorporates public NOAA and National Weather Service data including radar-derived hail information, gridded wind analyses, station observations, storm reports, warnings, and historical event records. The platform also standardizes and organizes records so users can more easily compare dates, locations, hazards, and source types.
The underlying distinctions remain important.
A radar estimate remains a radar estimate.
A station measurement remains a measurement at that station.
A Local Storm Report remains a report at its reported location.
A warning remains a warning.
StormAuditor publishes its methodology so users can review how these different data sources are incorporated and interpreted.
Frequently Asked Questions
How can I find hail history for my address?
Start with a historical hail map to identify relevant storms, then review radar-derived hail estimates, nearby ground reports, warnings, and historical storm records around the address. An address-level search is more useful than relying only on citywide storm history because hail can vary significantly across relatively short distances.
Can a hail map prove that hail hit my house?
No. A hail map can show radar-estimated hail or other mapped storm information near a property, but it generally should not be interpreted as direct proof that a particular hailstone struck a particular structure.
Can radar measure hail size at my roof?
Radar does not physically measure a hailstone on a roof. Products such as NOAA MRMS MESH use radar information to estimate hail size associated with a storm.
How do I find the highest wind speed at my address?
Begin by reviewing nearby measured weather-station gusts and then compare those observations with appropriate gridded analyses or address-level wind estimates. Unless an instrument was actually located at the property, a nearby station measurement should not automatically be described as the wind speed at the address.
What is the difference between a wind report and a wind estimate?
A measured wind report can document a gust observed by an instrument at a known location. An estimated wind value may be derived from meteorological analyses, models, nearby observations, or other datasets. Both may be useful, but they represent different types of information.
Where can I find official historical storm records?
NOAA's NCEI Storm Events Database provides historical records of significant weather events collected by the National Weather Service. The archive includes hail, thunderstorm wind, tornadoes, flooding, and numerous other event types.
Does weather data prove that a roof was damaged?
No. Historical weather information can help establish the timing, location, and magnitude of reported, observed, or estimated weather conditions. Determining whether a property sustained damage requires property-specific evidence such as inspection findings, photographs, construction information, and other relevant records.
Research the Weather Around a Property
The most useful historical-weather investigation is rarely based on one number.
Hail maps reveal broader storm patterns. Radar helps fill geographic gaps between reports. Ground observations document conditions at known locations. Weather stations provide direct wind measurements. Warnings establish timing and threat context. Historical databases preserve official storm records.
Address-level research brings those pieces together around the location that actually matters.
Use the StormAuditor Address Lookup to begin researching historical hail and wind activity at a U.S. property, or explore the Hail Map and Wind Map to investigate the broader storm first.
StormAuditor is an informational weather-research platform. Weather data may include measurements, human reports, radar-derived estimates, gridded analyses, warnings, historical event records, and other sources. Coverage and availability vary by source, location, date, and event. Weather information alone does not determine whether property damage occurred.
