Every January people from all around the world begin their annual temperature blankets. These blankets are fun projects to make and many Crochet Bloggers and Designers host CAL events (crochet alongs) with pattern suggestions and yarn color chart examples. This post includes helpful resources to get you started on your Temperature Blanket, including choosing colors, temperature ranges and different crochet stitches that work well for such a large project. You will also find free crochet Temperature Blanket patterns that you can jump right in to make own original project. I hope you have fun exploring these resources and free patterns!

Did you know that temperature blankets are sometimes called Weather Blankets and instead of crocheting based on a temperature range, you crochet based on different types of weather, like sunshine, rain and snow.

Temperature Blankets

  • Some blankets use the same stitch pattern for each row of the afghan, while others use multiple stitch patterns. I’ve included patterns for each option below.

Finding the Temperature Range for Your City

  • Before you choose you yarn colors, you need to find the temperature range for your area. 
  • To find your average temperature range, to help you plan your blanket, you can search online for your city and “average temperatures”.
  • This will give you a good starting point to decide the upper and lower temperature ranges you need to include for your blanket.

Here are some online resources to get you your average temperatures a little bit faster:

Average Temperature Ranges in Your City

Tracking Sheets for your Temperature Blanket

It is helpful to have a chart, or even just a printed calendar, to track the temperature each day and to check off the dates you have completed. We all know we can fall behind on our CAL projects so it is smart to have a tracking system in place to be ready to catch up. That way you don’t have to count how many rows you have done to find out what date you need to work on next!

Tips for Choosing Colors for Your Temperature Blanket

  • Typically you choose between 8-10 colors to represent the temperature ranges your location experiences within a calendar year and then you crochet 1 row for each day of the year.  More recently I have been noticing a wider range of colors being used with smaller increments between the temperature ranges they represent, this will make for a much more colorful blanket.
  • In the end, it is up to you how many colors you want to use in your blanket.
  • Lucy at Attic24 has a good post that explains how to choose colors for blankets here.

Jennifer did one color a week for a total of 52 rows for her shawl project. This made a shawl 52 inches wide. You could chain a multiple of 4 + 3 to make this stitch into a blanket instead. This post also includes a free crochet shawl pattern.

Choosing The Stitch Pattern for the Blanket

  • When choosing the pattern you want to crochet remember if you crochet 365 days worth of temperatures, that means your blanket is going to be 365 rows long.
  • Depending on the yarn weight and the crochet hook you use that finished blanket could be gigantic!
  • One way to make the blanket more manageable is to do 1 color per week for 52 weeks.
  • Or decide to do 1 color every set number of days. If you choose to do 1 temperature reading every 3 days, this will give you about 122 rows.
  • If you are making a full blanket and changing colors for every row, you may want to leave extra yarn on each end to allow you to leave the side edges as a fringe. Otherwise you will need to be weaving in 730 yarn ends before you add your edging.

Stitches that will work well for your blanket when you’re crocheting it in rows:

Gauge (everyone’s favorite topic)

  • If you can get the stitch you are using to give you 4 rows per inch, then you will have a 91 inch blanket length.
  • If the stitch gives you 5 rows per inch you will have a blanket about 73 inches long (before your edging).
  • TIP: You may want to try making your blanket using DK Weight Yarn to help you decrease it’s finished size.

An alternate way to make your Temperature Blanket

If I had the time to make a Temperature Blanket, I would make 380, 2″ inch squares – either using a simple granny square pattern, or just a plain crocheted square pattern.

This would allow me to have a finished blanket measuring 19 squares wide by 20 squares long (or 38 inches wide by 40 inches long) plus my border.

To me this seems a more manageable sized project and one that I can easily take with me on-the-go.

I also like the idea that I can make some of these squares in different temperature colors in advance for each of the temperature ranges and then I can join them when I have time each week.

Another unique idea worth considering is this one:

  • The video is not in English but it will show the simple Yo-Yo motif and how to join-as-you go (so each day you can just add the next one to the one from the day before). Watch the video here.

  1. Hi Tam 🙂 because I made a typo! I’ve fixed it now in the post. You are the very first person who noticed my error. It should have been 52 weeks. Thank you for letting me know, Rhondda

  2. Hi. Curious why you chose 56 weeks or 380 days for a one year afghan?? A year has 52 weeks and 365 days (366 in leap year). Why’d you make it 4 weeks (or 15 days) longer??

  3. Great ideas! Another site you can use to get weather data and plan your gauge is temperature-blanket.com.

  4. I’m planning on making two temperature blankets, one for January thru June and one for July through December. I’ll do the same colors and stitch and I think they will look nice together.

  5. I have started mine. I have chosen a hexagon design. Instead of doing an average temperature – which to me does not really give an accurate temperature of your area. I am doing both a high and low temperature of each day. Each of my hexagons are approximately 5″ across. I have introduced this idea to my crochet group that I am a member in Facebook. They love the idea. This is a leap year – so it works out with the hexagon motif. All the odd rows with be 22 hexagons, and all the even rows will be 21 hexagons. It will end up with 17 rows of 366 hexagons. I googled a hexagon graph and it worked out very well.

  6. I have not crocheted this yet. But it got my attention, it is totally different.
    You also have a lot of information for crocheting this. Think it will be fun!!

  7. Hi Rene, I purchased mine at Michael’s craft store it was in the ribbon aisle there and came in a couple different colors. I have also ordered online from amazon when it went on sale last winter. Hope this helps! Rhondda
