What is a Temperature Blanket?

A form of Information Art, a temperature blanket is a crocheted or knitted representation the temperature of a location over time. Each row or section of the project represents a day’s weather. There are many types of temperature blankets, but they all follow a general principle: the color of each section is based on meteorological events.

Making a temperature blanket

1) Create a Gauge: To make a temperature blanket, first choose yarn colorways and make a temperature gauge (sometimes called a color gauge or color chart). You can choose any number of colors. Then assign each color a temperature range. See the example temperature gauge below.

2) Record Weather Data: Next, record the temperature over time (or use historical weather data). You can keep track of the average temperature that day, the maximum or minimum temperature, or another meteorological event, like rain or snow. You can even use multiple data points for each day to create more variations in your pattern. How or which weather variables you choose to record is up to you; what’s important is that you are consistent in your tracking.

3) Stitch your Pattern: When you have the weather data you want, for each day, crochet or knit a section of your blanket using the yarn color of that day’s temperature, according to your color gauge. For example, using the example color gauge above, if the day’s temperature was 52°F, stitch a section of the blanket using the 9th yarn color.

You can stitch any pattern you like. A standard temperature blanket features one stitched row per day, but you can make chevron patterns, squares, corner-to-corner designs, incorporate the minimum and maximum temperature in the same section, and many other variations. The possibilities are practically endless.


Temperature blankets are unique and completely customizable. To make your project, you could use any of the following principles:

  • Use either the maximum, minimum, or average temperature (or a combination of them) for each section
  • Include other meteorological events in the pattern, such as rainfall or snowfall
  • Group or mark sections to represent weeks, months, or other units of time
  • Include the color gauge in the project itself
  • Include more than one location in the pattern
  • Use the color gauge to crochet or knit a different object, such as a scarf, rug, or sweater
