About Temperature Blanket Planner
Pick a US city and a year. Temperature Blanket Planner turns that place’s actual daily temperatures into a color chart for a crochet or knit blanket, one row per day.
The weather data
Every number comes from NOAA’s National Centers for Environmental Information (NCEI): the daily maximum and minimum temperatures (TMAX/TMIN) in the Global Historical Climatology Network – Daily dataset, fetched through NCEI’s Access Data Service. NOAA data is public domain.
For each of the 285 cities we cover, we matched an approximate city-center point to a nearby station with a long, mostly complete record, using NOAA’s published station and inventory lists. Past years are cached once fetched. The current year refreshes at most once a day, so the latest days can lag slightly behind NOAA. If a station skipped a day, we estimate it from the neighbouring days and mark it “est.” in the daily table, so you always know which rows are measured.
How the chart is built
Temperatures are sorted into bands, eight by default, either automatic or set by you. Each band gets a color from one of six palettes. Yarn estimates multiply your gauge and blanket width by the number of rows in each color band.
Who maintains it
We’re a small team who like it when real data turns into something you can hold. The planner, the city list and the guides are ours to fix. If a station looks wrong for your city, or your town isn’t listed, email support@temperatureblanket.site with the place and year.
