Crocheted Temperature Blanket 21

NOTE: I wrote this in December 2015, so “this year” means 2015. My 2017 temperature projects are described here. Happy reading!

It’s getting close to the end of the year again, which means my mind is turning to trying to do a temperature blanket again. I tried one this year but I think I made it too complicated to keep it going consistently. Moving toward the beginning of the year didn’t help either.

For those unfamiliar with the concept, I’ll explain what a temperature blanket is. It’s a blanket you add a row to each day. The color of the row changes based on the temperature of each day. It makes a neat colorful record of the temperatures of the years. I’ll break down the components for you.


Temperature Scale

I assigned a temperature range (in Fahrenheit) for each color. Since I chose to use Red Heart Super Saver yarn, so I’ll use their color names for my example.

Red Heart Super Saver Temperature Range

I accidentally switched the carrot and pumpkin colors!! Download available at the end of the blog post.

In case you can’t read that:

  • 90 and above: cherry red
  • 80 to 89: carrot
  • 70 to 79: pumpkin
  • 60 to 69: bright yellow
  • 50 to 59: lemon
  • 40 to 49: light blue
  • 30 to 39: light periwinkle
  • 20 to 29: royal
  • Below 20: lavender

I take the “official” high of the day from the local NOAA/NWS weather report and crochet a row of that color each evening. You could use the temperature at a set time each day like noon or 3 pm. I’ve also seen suggested it that you could change yarn colors for if it rains or snows. At that point I would feel like it’d be more of a weather blanket, though. Not a bad idea, just a different concept.

A tip for the temperatures: If you can’t crochet a row one day (or several), write down the temperature on a calendar to remember it so you can catch up later.


Adjusting Your Temperatures

Back to business, time to talk adjustments to my temperature assignments. They work here in Indiana, but they would probably need to be adjusted for somewhere with a different climate.  I’ll include a possible range for somewhere further south (I’ll use Florida since I have friends living there, though I’m guessing on their normal temperatures).

  • 100 and above: cherry red
  • 90 to 99: carrot
  • 80 to 89: pumpkin
  • 70 to 79: bright yellow
  • 60 to 69: lemon
  • 50 to 59: light blue
  • 40 to 49: light periwinkle
  • 30 to 39: royal
  • Below 30: lavender

So you can see the temperature range is easily adjusted for your local climate. If your days are usually hotter, move the temperatures up. If the days are usually colder, move them down. Also, if your local temperatures don’t vary much you can shrink the increments to 3 degree differences. Thanks to those in the Facebook crochet groups that mentioned this idea (you can see it implemented in a way on another blanket of mine here).

If you’re still having a little trouble figuring out how these adjustments work you might find this post helpful.

The Stitches

This year I tried to change the stitch each month, but I think that was too complicated. This year I did a single crochet for January; a single crochet, chain two for February; and a double crochet shell for March. March is when I fell off the wagon, so I didn’t think up any more stitches.

This coming year I’ll trade off between single and half-double crochet stitches. I’d add double or treble stitches, but I don’t want the blanket getting too long.

  • January: single crochet
  • February: half-double crochet
  • March: single crochet
  • April: half-double crochet
  • May: single crochet
  • June: half-double crochet
  • July: single crochet
  • August: half-double crochet
  • September: single crochet
  • October: half-double crochet
  • November: single crochet
  • December: half-double crochet

Of course, you can feel free to adjust the stitches to your liking. I just recommend you don’t make it too complicated of a stitch or you won’t get your blanket done. I should know. 😉


Estimating Blanket Length

If you’re curious, you can estimate how long your blanket will be at the end of the year. I’ll show you an example with my version of the blanket. In the Super Saver yarn I know my single crochet stitches are about 3/8 inch tall and my half-double crochet stitches are 1/2 inch tall. If I take the amount of days I’d be single crocheting (184) and multiply it by 3/8 inch (.375) I’d get 69 inches of single crochet stitches. I’d do the same for the half-double crochet: 182 (this year’s a leap year) x .5 = 91 inches. Add the two figures and you get that my temperature blanket should be around 160 inches (13 1/3 feet) this year. Now you see why I don’t want to add larger stitches. 🙂

I’ll note here that this blanket ends up as more of a bed runner than an actual blanket. You can add less or more chains/stitches to get different products. I’ve seen suggestions for full blankets (around 300 stitches across), scarves (around 25 stitches across), and more.

Temperature blanket pattern

I am including a pattern for those who like following a pattern, but this temperature project is VERY easy to customize. You can change the colors, the stitches, the yarn, and the list goes on. Have fun!


Difficulty: Easy/Beginner


Size: My blanket will be about 160 inches long by 36 inches wide. Yours will vary depending on yarn and how tight/loose you crochet. Gauge is NOT important for this project.


Yarn: 1 each of Red Heart Super Saver (7 oz) in cherry red, carrot, pumpkin, bright yellow, lemon, light blue, light periwinkle, royal, and lavender (or pick 9 colors in the yarn of your choice)


Hook: H or your choice



Row 1: On January 1st, ch 101 in the high or temperature color of the day.  Sk 1 ch, sc in each stitch across, turn. (100 sc)

Row 2: On January 2nd, ch 1, then sc in each stitch across in the high or temperature color of the day, turn. (100 sc)

Rows 3-31: Continue to crochet a row each day, turning after each row. The stitch and color are determined by the temperature scale and month pattern you choose. For example, January 15th with a high of 20 (brr!) would mean I’d single crochet a row of royal.

Row 32: On February 1st, ch 2, then hdc in each stitch across in the high or temperature color of the day. (100 hdc)

Rows 33-365 (or 366 on a Leap Year):  Continue to crochet a row each day. The stitch and color are determined by the temperature scale and month pattern you choose. A May 17th high of 72 would be a single crochet row of pumpkin. A December 6th high of 51 would be a half-double crochet row of lemon.



For more of a scarf (my test one was 9″ wide): ch 26, sk 1 ch, sc in each stitch across, turn (25 sc) and continue in the rest of the pattern using 25 in place of 100

For a BIG blanket (my test one was 108″ wide): ch 301, sk 1 ch, sc in each stitch across, turn (300 sc) and continue in the rest of the pattern using 300 in place of 100


Things to remember:

  • In single crochet, the ch 1 doesn’t count as a stitch, while the ch 2 in half-double crochet does. This means you will work a stitch into the top of the turning chain of each half-double crochet row. You could also stitch into the first stitch if you want. Go with what looks best to you, just check your count from time to time.
  • When changing colors, it’s easier to change it by picking up the new color as you finish the last stitch of the row.
    • In single crochet, you do this by doing the last stitch until there are two loops on the hook, then yarn over with the new color and pull it through both loops. Then continue with the pattern in the new color.
    • In half-double crochet, you do this by doing the last stitch until there are three loops on the hook, then yarn over with the new color and pull it through all three loops. Then continue with the pattern in the new color.
  • Sort of obvious, but you will have to buy a new skein of a color when you run out of one. You could estimate how many of each color you’d need by looking at your area’s typical temperatures, but starting with two of each should be more than enough to get you through a few months unless you’re lucky enough to have the temperature staying around the same each day for a long time. I live in Indiana so that doesn’t happen to me.

I’ll note that the concept of a temperature blanket isn’t mine, but the pattern is my work.
