NOAA Weather Documentation Report for construction delay documentation

The report is a PDF of day-by-day NOAA GHCN-Daily weather compared with a same-calendar-window baseline from up to the 10 prior years (minimum 5). You download it after payment.

What is a Weather Delay Claim Report?

A weather delay claim report is a PDF of NOAA GHCN-Daily observations for the dates you select, compared with a same-calendar-window baseline from up to the 10 prior years (minimum 5). Days outside mean + 1 standard deviation are flagged in the table. People use the PDF to:

• Read precipitation, temperature, and wind where the station reports it
• See which days fell outside the historical baseline
• Provide objective weather data
• Attach the PDF to a time-extension request

Why Weather Documentation Matters

Time-extension terms are set by your contract (such as AIA A201); check your contract's own language. This report does not decide whether a day supports a time extension.

Each day in the PDF is compared with the historical mean and standard deviation for that calendar window. A flag means the measurement fell outside mean + 1 standard deviation.

What Our Report Includes

• Day-by-day weather data table showing precipitation, temperature, and wind where the station reports it, from NOAA GHCN-Daily
• NOAA station identification with distance from project location and data coverage percentage
• Abnormal weather determination using a same-calendar-window baseline from up to the 10 prior years (minimum 5)
• Statistical methodology (mean + 1σ thresholds from that baseline)
• Clear methodology notes explaining the baseline approach
• Source citations referencing official NOAA GHCN-Daily data
• PDF report

Automated delivery after checkout

The report is delivered in minutes using real NOAA GHCN-Daily station data and a same-calendar-window baseline from up to the 10 prior years (minimum 5). No human review delays. No waiting.

Pay $199, get your weather documentation with that historical baseline immediately, and move forward with your claim.

Common Weather Delay Scenarios

• Heavy precipitation preventing concrete pours or site work
• High winds stopping crane operations or roofing work
• Extreme temperatures affecting material installation
• Multiple consecutive days of adverse conditions
• Severe storms causing site evacuation
