What is a Crochet Temperature Blanket?

So, you may be wondering exactly what is a temperature blanket? Well, crochet temperature blankets are a fun and creative way to track the weather throughout the year. A temperature blanket is a unique kind of crochet blanket that reflects the temperature of a particular place over time.

The concept is simple: you select a color for each temperature range, and then crochet a row of the blanket in the corresponding color for each day’s high temperature. By the end of the year, you’ll have a beautiful, unique blanket that represents the changing weather patterns throughout the year in your area.

Guide to Crocheting a Temperature Blanket

Here’s a step-by-step guide to creating your own crochet temperature blanket:

Choose your temperature range

The first step in making a temperature blanket is to decide on your temperature range.

You can choose any range you like, but the most common ranges are 10-degree increments 50–59 degrees, 60–69 degrees, etc.) or 5-degree increments (e.g., 50–54 degrees, 55–59 degrees, etc.).

Decide on a color palette

Choose colors that correspond to the temperature ranges for your area. For example, you might pick blue for temperatures below 40 °F, green for temperatures between 40-50 °F, yellow for temperatures between 50-60 °F, orange for temperatures between 60-70 °F, and red for temperatures above 70 °F.

  • Below 30 °F: White
  • 30-39 °F: Light blue
  • 40-49 °F: Dark blue
  • 50-59 °F: Green
  • 60-69 °F: Yellow
  • 70-79 °F: Orange
  • 80 °F and above: Red

You can also pick different colors for different temperature ranges, or use shades of the same color. Above in the temperature blanket chart is an example of a range of temperatures with colors that you can use in a temperature blanket.

Pick your Location

Decide on a location that you will use to record your temperatures. Will it be your home, cabin, or a special place that you love? Once you pick the place you want to use for your temperature blanket, then you can move on below to create a temperature chart for your blanket!

Create a temperature chart

Record the temperature ranges and corresponding colors on a chart. You can find temperature data from your local weather service or app, and then use a spreadsheet or paper to organize the data into temperature ranges and corresponding colors.

Gather your materials

You’ll need a few supplies to make your temperature blanket, including:


You’ll need a different color of yarn for each temperature range you’ve picked. The weight of yarn is up to you, so if you’d prefer a worsted weight yarn or a bulky 6 yarn, it would work for crocheting a temperature blanket. Keep in mind, this will change the finished size of your blanket.

Crochet hook

The size of the hook will depend on the weight of your yarn. You can find the recommended crochet hook size on the yarn label of the yarn you have picked.

Tape measure

You’ll use this to measure the length of your blanket as you go.

Optional Supplies & Tools

You may also need stitch markers, a yarn needle for weaving in ends, and a pattern or graph to keep track of your color choices.

Start Crocheting

Once you have your plan in place, it’s time to start crocheting! Begin by chaining the desired length of your blanket. Take a look at my blanket size chart to figure out the size you’d like, and then start crocheting a row for each day’s temperature.

As you crochet, make sure you keep track of the temperature for each day, so you can use the correct color yarn for each row.

Crochet the first row

Using the color that corresponds to the temperature for the first day, crochet a row of your desired stitches across the foundation chain. Remember to keep track of the temperature for each day and switch colors accordingly.

Decide on Stitches to Use

You can use any stitch you like, but the most common stitch for temperature blankets is the single crochet. The single crochet stitch is recommended because as you work up a blanket throughout a year, you can imagine it will be a big blanket when it is finished.

Continue crocheting rows

Each day, check the temperature and switch to the appropriate color to crochet a row for that day. You can choose to crochet one row per day, or you can crochet several rows at a time and then switch colors as needed.

Weave in ends

As you crochet, be sure to weave in the ends of your yarn as you go. This will save you time and effort later on. You can use a yarn needle to weave in the ends, or you can use the crochet hook to weave in the ends as you crochet.

Finish your blanket

Once you’ve completed all the rows for the year, it’s time to finish your temperature blanket.

Add a border

Once you have crocheted enough rows to cover the desired length of your blanket, add a border. You can use a simple single crochet border or a more elaborate stitch pattern.

Block (optional)

After you have completed the border, weave in any remaining ends, and then block the blanket to even out the stitches and give it a finished look.

Tips for Crocheting a Temperature Blanket

  • Keep your gauge consistent to ensure that your blanket stays the same size throughout.
  • Choose a yarn that is easy to care for, as temperature blankets can be quite large and heavy. Four weight yarns are perfect for temperature blankets since they are not heavy, easy to find and come in various colors.
  • Use a stitch marker or paperclip to mark the beginning of each row.
  • Keep track of the temperature and color changes using a notebook or spreadsheet.
