About WorkWindow
WorkWindow answers one narrow question well: does the next 10 days give you a weather window for the outdoor job in your hand — staining, painting, sealing, pouring, coating, or seeding? It exists because the answer currently lives in two places that don't talk to each other: the fine print on a product label and the hourly forecast.
The problem
Every can, pail, and bag ships with a weather spec: a temperature range, dry hours before and after, an overnight floor, sometimes a humidity ceiling. Every weather app ships the data to check that spec. Nobody connects them, so homeowners stand in the driveway doing dew-point arithmetic — or skip it, and find out at 9 p.m. what the label meant.
What this site does
One published ruleset per task — a consensus of typical label requirements, spelled out on the methodology page — scored hour by hour against a live 10-day forecast for your city. Each day gets GOOD, MARGINAL, or NO, with the failing rule named in plain words. Behind that sits NOAA's 1991–2020 climate normals, counted into workable days per month, so every page also answers the planning question: which months are even worth watching here.
What this site is not
Not a manufacturer, not a contractor referral service, and not a substitute for the label on your product. When our table and your can disagree, the can wins — every page says so, because it's true. Concrete pages cover small DIY pours only; structural work belongs to your engineer and ACI specifications.
Who runs it
WorkWindow is an independent, data-driven site. It is built from public data — NOAA normals, Open-Meteo forecasts, Census geography — by people who have personally re-stained a deck twice in one season because the first attempt met a thunderstorm at hour 18.
