What was the weather at the time of the crash? Get a cited answer.
Pull a source-cited record of the rain, fog, darkness and low-sun glare at the exact crash location and minute, in the location's own local time, to build or rebut causation and comparative fault early.
Conditions.Site generates a clear, cited report of the historical weather, sun position and moon position for any past date and time, down to the minute, at any address, intersection or GPS point. For a car-accident case, that means a defensible record of what the driver actually faced: the rain, the visibility, the darkness, whether the sun sat low in the driver's eyes. Every value is traced back to the public source it came from.
The problem
Where the usual sources come up short when you need to establish what the conditions were.
The complaint says it was raining. Can you prove it?
A client's account of the weather is not evidence. You need an independent, cited record of precipitation, visibility and cloud cover at that place and minute before you frame causation or comparative fault.
Retaining an expert too early is expensive
A forensic meteorologist costs real money and takes time. On many files you first need a fast read on whether a conditions theory is worth pursuing at all, not a full retainer.
"The sun was in my eyes" is easy to claim, hard to check
Low-sun glare is a common defense and a common cause. Without the sun's altitude and azimuth at the crash minute, and without knowing whether it cleared the horizon at that spot, you are arguing it blind.
Free weather sites don't cite anything
A screenshot from a consumer weather app names no source, no station and no method. It won't survive scrutiny in a demand letter or a deposition, and it may be for the wrong day or the wrong town.
How it's used
Test a rain-and-visibility theory in a demand letter
Before drafting, pull the precipitation, visibility and cloud cover for the intersection at the crash minute, cited to NOAA station data and reanalysis, so the demand rests on a record rather than a recollection.
Rebut a low-sun-glare defense
Check the sun's altitude and azimuth at the crash time and direction of travel. If the sun was already below the visible horizon, accounting for terrain and nearby buildings, the glare claim is far harder to support.
Establish it was dark for a nighttime pedestrian case
Get the exact sunset and twilight times at the crash location and date, so you can show the roadway was in darkness or civil twilight when the collision occurred.
Decide whether to retain a forensic meteorologist
Use the cited report as an early screen. If the conditions clearly support your theory, you retain the expert with confidence; if they don't, you've saved the fee and reframed the case.
What you get
Every value is cross-checked across independent public sources and cited back to its origin.
Weather cross-checked across independent sources
Temperature, wind, precipitation, cloud cover, humidity, visibility and pressure are reconciled across ERA5 reanalysis, NOAA/NWS station records and personal weather stations, with every value cited to the source it came from.
Sun position and glare, terrain-aware
Altitude and azimuth at the exact minute, plus sunrise, sunset, solar noon and twilight. Local terrain and nearby buildings factor into whether the sun was above the visible horizon at the site.
A clean, cited PDF report
A one-page visual summary, a per-source comparison table, an hourly table and per-station detail. Every number is traceable to its origin, so the record travels with the file into a demand or a deposition.
Exact place, exact minute, local time
Search an address or intersection, or drop in GPS coordinates, and set the date and time to the minute in the location's own local time. Saved report history is kept under your account.
How it works
Enter the crash location and minute
Search the address or intersection, or paste GPS coordinates, then set the accident date and time to the minute. The report uses the location's own local time.
We reconcile the public record
Conditions.Site pulls historical weather, sun position and moon position from multiple independent public sources and cross-checks the values against each other.
