How to Find Free Hail and Wind History at an Address: 2026 Guide
By StormAuditor Editorial Team · Published 2026-08-19 · Updated 2026-08-19
Based on public NOAA and National Weather Service records, published under StormAuditor's methodology and data-source standards. Radar-derived hail sizes are estimates unless attributed to a ground report.
Damage-threshold ranges in this article are general guidance synthesized from industry and federal research — IBHS building-performance research, NWS severe criteria, and product standards such as UL 2218 (hail impact resistance) and ASTM D3161/D7158 (shingle wind ratings). Actual performance depends on product rating, age, installation quality, exposure, and impact characteristics — thresholds describe when damage becomes possible, not when it occurs.
Historical weather information can help establish the timing, location, and magnitude of reported, observed, or estimated weather conditions
How to Find Hail and Wind History at an Address: 2026 Property Weather Guide
Did a property get hail or strong wind on a certain date? The answer is rarely in one perfect database.
Weather history research usually means comparing several kinds of evidence: hail maps, wind maps, radar estimates, nearby weather stations, storm reports, warnings, and official records.
Each source answers a slightly different question.
Homeowners, roofers, public adjusters, insurance staff, attorneys, researchers, and property managers all do this work. For them, knowing those differences often helps more than finding the biggest number on a weather map.
This guide shows how to research hail history and wind history at a specific address: what data to look for, and how to read it without claiming more than the records show.
Start With the Address, Not Just the City
Weather can change over short distances.
A storm may drop large hail on one neighborhood and little or none a few miles away. A downburst may push a strong gust past one weather station while a nearby station records much less.
So a search like "hail in Dallas on May 20" and an address-level hail lookup do not always answer the same question.
A good property weather search starts with three things:
- The exact property location
- The date, or a range of possible storm dates
- The type of weather you are looking for
If you don't know the date, start by finding likely storm dates. Then look at each event.
StormAuditor's Address Lookup is built around this property-first approach.
How to Find Hail History at an Address
No national network measures hailstone size at every house. So hail research draws on several sources that fill in for each other.
1. Look at the wider hail pattern
A historical hail map or hail swath shows storms that crossed the area.
Radar is very useful here. It covers the ground between single reports.
NOAA's Multi-Radar/Multi-Sensor system makes the Maximum Estimated Size of Hail product, called MESH. MESH uses radar data to estimate the hail size in a storm. NOAA describes MESH as an estimate of hail size, not a measurement of hailstones at each property.
That difference matters.
Say radar estimates 1.5-inch hail near an address. The right conclusion is that radar showed hail-producing conditions in that area. It does not mean someone measured a 1.5-inch hailstone on that roof.
Use StormAuditor's Hail Map to explore the wider pattern before you narrow in on an address.
2. Check nearby hail reports
Ground reports are another kind of evidence.
National Weather Service Local Storm Reports can record hail size, damaging wind, measured gusts, tornadoes, flooding, and other major weather. Reports can come from trained spotters, emergency managers, police, the public, the media, and others.
A hail report may include:
- A measured hail size
- An estimated hail size
- A comparison to an object
- Where it was reported
- When it was reported
- Who sent it in
Distance matters.
A measured 1.75-inch hail report two miles from a property is good evidence that large hail fell nearby. But it is still a report from two miles away. It is not a measurement at the property.
Good research keeps both the size and the distance from the address.
3. Compare radar and ground reports
Radar estimates and ground reports work best when you don't treat them as the same thing.
Radar helps answer:
Where did the hail part of the storm seem to go?
A ground report helps answer:
What hail did someone actually see at this spot?
When both point to similar conditions in the same place and time, the event is easier to understand.
When they disagree, that is useful to know too.
Hail can vary a lot across one storm. No single source should override all the others by default.
How to Find Wind History at an Address
Wind is a different problem.
Unlike hail, wind is measured all the time at many official weather stations. But those stations are miles apart. Large areas have no direct instrument reading.
So a good wind search combines measurements with what is known about the wider wind field.
1. Find nearby measured wind gusts
Official ASOS and AWOS weather stations are very useful. They give direct instrument readings.
Say a station four miles from a property recorded a peak gust of 61 mph.
The strongest factual statement is:
A weather station about four miles from the property recorded a 61 mph gust.
That is not the same as:
The property had a 61 mph gust.
The first describes a real measurement and where it was taken. The second moves that measurement to another place.
Many things affect how well a nearby station stands in for the property: exposure, terrain, storm structure, trees, buildings, distance, and how local thunderstorm winds can be.
2. Look at the wider wind field
Weather stations are not at every address. So meteorologists also use gridded analyses and weather model data to describe conditions between stations.
StormAuditor's wind method uses public weather datasets to estimate the peak wind at an address. Nearby station readings stay in view as supporting context. We publish the method and our validation results so anyone can check how the estimates are made.
See the StormAuditor Wind Methodology for the technical details.
An estimated wind value should still be called an estimate. It is not an instrument reading taken at the property.
3. Review wind storm reports
Local Storm Reports add useful context for thunderstorm wind events.
Reports may describe:
- Measured wind gusts
- Estimated wind speeds
- Trees or large limbs down
- Power lines hit
- Damage to buildings
- Thunderstorm wind damage
These records can show local impacts away from any official weather station.
But an estimated wind report and a measured gust are different kinds of evidence. Keep them labeled that way.
Hail Maps and Wind Maps Are Starting Points
Maps are very useful. They make the geography of a storm easy to see.
They can quickly show:
- Where stronger conditions were estimated
- How a storm moved through an area
- Where reports were clustered
- Which towns were near the event
- Whether an address was near or inside a mapped swath
But a colored shape on a map is not a perfect boundary.
Weather does not suddenly change because a property sits one pixel outside a line.
Hail size, wind speed, and storm impacts change smoothly across space. The map is a simplified picture of the data.
That makes maps excellent discovery tools. Follow them with a closer look at the records around the address.

What If You Don't Know the Storm Date?
This is one of the most common problems in weather research.
An owner may remember a big storm "sometime last spring." A contractor may find damage that calls for a look at past severe weather. An adjuster or researcher may inherit a file with no clear event date.
Don't guess. Work backward from the record.
Search for likely dates
Look for dates when the area had:
- Significant hail
- Strong thunderstorm wind
- Measured gusts nearby
- Severe weather reports
- Relevant NWS warnings
- Major regional storm systems
StormAuditor's Date-of-Loss Database organizes severe weather dates from public NOAA and NWS records. You can filter it by location, time period, and hazard.
A likely date is a research lead. It is not proof that a property was damaged that day.
Once you find promising dates, research each event at the address.
Don't Confuse a Warning With an Observation
Warnings are among the easiest weather records to misread.
A Severe Thunderstorm Warning says severe weather was happening or expected in the warned area.
It does not show that every property inside the warning area got the highest hail or wind listed.
For example, a warning may mention 70 mph wind and 1.5-inch hail while the strongest part of the storm crosses only part of the area.
Warnings are valuable for:
- Timing
- Storm movement
- Where the storm was
- What threats were expected
- What forecasters knew during the event
Just keep them labeled as warnings, not measurements.
Official Storm Records Are Useful, but They Arrive Later
NOAA's National Centers for Environmental Information keeps the Storm Events Database. It holds records of significant weather events collected by the National Weather Service.
These records are very useful for older storms.
They are less useful as the only source for very recent events, because the database is not updated in real time. NCEI explains that Storm Events data usually go through an NWS submission and processing cycle before they reach the archive.
For recent storms, researchers may lean more on near-real-time reports, observations, warnings, radar products, and other records until the later entries appear.
Why Two Weather Sources May Disagree
Different values from different weather tools do not mean one source is wrong.
They may be measuring or estimating different things.
Take these made-up records from one 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 mentions possible 2-inch hail
Those four numbers do not describe the same observation.
The same goes for wind:
- An airport measures a 54 mph gust
- A storm report estimates 65 mph wind somewhere else
- A gridded analysis estimates 48 mph near the property
- A warning mentions 70 mph gusts
The goal of research is not to pick the biggest number.
It is to understand what each value means, where it came from, when it happened, and how close it was to the property.
A Better Workflow for Address-Level Storm Research
For most properties, follow this order:
Step 1: Find possible storm dates
Search past activity for the city, county, or state.
Step 2: Open the hail or wind map
See whether the wider storm crossed the area.
Step 3: Center the research on the address
Review the weather records near 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 these maps of data to understand conditions between direct observations.
Step 6: Check warnings and event records
Use them for timing, storm context, and support.
Step 7: Keep measurements and estimates separate
Don't describe radar estimates, model values, warning threats, and station measurements as if they were the same thing.
Step 8: Keep the uncertainty in view
Weather evidence can describe the storm around a property. On its own, it cannot decide whether a part of a building was damaged.
How StormAuditor Organizes the Research
The United States has a lot of public weather data. But it is spread across many systems.
StormAuditor brings the relevant parts of that record into one practical workflow for property research.
Depending on the tool and the event, StormAuditor uses public NOAA and National Weather Service data. That includes radar hail data, gridded wind analyses, station readings, storm reports, warnings, and historical event records. The platform puts records in a standard form, so you can compare dates, places, hazards, and source types more easily.
The key differences still hold.
A radar estimate is still a radar estimate.
A station measurement is still a measurement at that station.
A Local Storm Report is still a report at its stated location.
A warning is still a warning.
StormAuditor publishes its methodology so you can see how each data source is used and read.
Frequently Asked Questions
How can I find hail history for my address?
Start with a historical hail map to find the storms that matter. Then review radar hail estimates, nearby ground reports, warnings, and storm records around the address. An address-level search beats citywide storm history, because hail can change a lot over 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 data near a property. It should not be read as direct proof that a hailstone struck a certain building.
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 data to estimate the hail size in a storm.
How do I find the highest wind speed at my address?
Start with nearby measured station gusts. Then compare them with gridded analyses or address-level wind estimates. Unless an instrument stood at the property, don't call a nearby station reading the wind speed at the address.
What is the difference between a wind report and a wind estimate?
A measured wind report can record a gust read by an instrument at a known place. An estimated wind value may come from weather analyses, models, nearby readings, or other data. Both can be useful, but they are different kinds of information.
Where can I find official historical storm records?
NOAA's NCEI Storm Events Database holds records of significant weather events collected by the National Weather Service. It covers hail, thunderstorm wind, tornadoes, flooding, and many other event types.
Does weather data prove that a roof was damaged?
No. Weather history can help show the timing, location, and size of reported, observed, or estimated weather. Deciding whether a property was damaged takes property evidence, such as inspection findings, photos, construction details, and other records.
Research the Weather Around a Property
The most useful weather research rarely rests on one number.
Hail maps show the wider storm pattern. Radar fills the gaps between reports. Ground observations record conditions at known places. Weather stations give direct wind readings. Warnings set the timing and threat context. Historical databases keep the official storm record.
Address-level research brings those pieces together around the place that matters.
Use the StormAuditor Address Lookup to start researching past hail and wind at a U.S. property. Or explore the Hail Map and Wind Map to look at the wider storm first.
StormAuditor is a weather research platform. Its data can include measurements, human reports, radar estimates, gridded analyses, warnings, historical event records, and other sources. Coverage and availability vary by source, location, date, and event. Weather data alone does not decide whether property damage occurred.
