Rain days by month in Memphis, TN
Mean days with 0.10 in (2.5 mm) of rain or more, 2016–2025, NOAA GHCN-Daily station Memphis Intl Ap. 78 days a year.
What it means for a schedule
A project in Memphis should expect about 78 days a year with enough rain to count as a weather day under a 0.10 in rule. The wettest months are Mar, Feb, Dec (9, 9, 8 days); the driest are Sep, Oct, Nov. A contract that allows the mean number of weather days per month grants an extension only for the days above it, so the monthly baseline, not the annual total, is what a claim is measured against. Snow, freezing and wind rules add days on top of rain.
The weather-day tool takes your contract's own thresholds, gives the mean and 80th percentile for each month at the station nearest your site, and tracks actual weather days against that baseline every month, with a PDF for the claim file.
