Pictured above is the birth year temperature blanket that I crocheted for my youngest son. He is a strong-willed, Spider-Man obsessed little boy that can melt your heart with one smile and knows how to use that smile to get him out of trouble.

Even though his first year was rough with days filled with battling acid reflux and colic, he emerged from the battle victorious.

He may never remember the first year of life, but he will always know how the temperatures were during that year with a temperature blanket. It is something special and unique for him. It will be completely different from his brother’s and anyone else’s.

What is a Birth Year Temperature Blanket?

Temperature blankets are usually a year-long project that people start at the beginning of the year to record the varying temps. However, a Birth Year Temperature Blanket is different.

Instead of starting with January 1 of a year, you start with the date person is born.

The ending date of the blanket will be the day before the person’s 1st birthday.

How do I find the temperatures to crochet the blanket?

I used Weather Underground’s historical data to find the temperatures I needed.

Make sure you type in the location of the person who is getting the blanket. It is a blanket about them, so make sure the area is correct for them.

After that, enter the birth date. Don’t worry. You will be able to change things on the next page.

If the History tab does not tell you the information you need, click on the Calendar tab. You can change the month and years in the calendar section and start making a chart.

How did you organize your data?

I used Microsoft Excel to organize my data. If you don’t have Excel, you can use Google Sheets; it is a free app.

I make a few columns: Date, Temp, Color.

In the Date column, enter each date of the birth year.

The Temp column will hold the high temperature for the day. Make sure you are using the actual temperature.

The Color column will include the color of yarn for that temperature. Not sure what colors to use? Check out my temperature blanket color chart.

Once everything is in the chart, print, and start crocheting.

I kept a pencil nearby so I could check off each row and keep track of where I am at in the process.

How does this data translate to a crochet pattern?

Each date in your chart will become a row in your blanket. You will crochet one row per day in the color suggested.

Your temperature blanket will be 365 rows long.

The blanket shown uses single crochet stitches.

You may make it as wide as you like, but I based my blanket off of this temperature blanket pattern.

Did you put an edging on your blanket?

No, I have not added an edge to my birth year temperature blanket. I couldn’t choose what color to make it, so I left it as is without a border.

However, you can add an edge to blanket you crochet.

How long does your temperature afghan measure?

I used only single crochet stitches for my temperature blanket. I was afraid with the 365 rows it would be too long with taller stitches.

My blanket measured 10 feet 7 inches long. HUGE!

Who are you going to crochet a blanket for now that you understand how to make one?


  1. I made 1 for my daughter using the hourly temperature for the day she was born. I did 3 dc rows per hour since she was an adult when I made it. She loved it. My hubby was so impressed with it that I did lots of research and found the average temperature for each of his 68 birthdays. I used 1 row of sc, a row of dc, and another row of sc for each year to make it long enough. I also stuck with shades of green and blue with 1 row each of tan, white and pale yellow. He is so proud of it and shows it to everyone who comes to visit. He even asked me for a chart showing What temp each color represents. It was a lot of work, but worth every minute when I saw the look on his face! Temperature blankets are a great gift!

    1. I LOVE this idea!!! Isn’t it wonderful when you give a crocheted gift to someone and they love it so much they have to show everyone! Totally worth it. :)

  2. I’m making a c2c temperature blanket for my first year of marriage (which was 2015/16), one corner will be our wedding day and the end corner will be our first anniversary. I originally was going to do the high and low temp each day as granny squares, but realized I didn’t want to sew all those together. So I’m crocheting 2 strands at a time c2c, 20 blocks per day, the high and low for each day. It’s fun because even if the high temp each day is the same, the low might be different. It’s going to be huge and heavy but I’m very excited about it.
    I chose Caron Simply Soft and I’m doing it all in shades of greens, blues and purples, darker colours are hot, lighter colours are colder. Where we live we have a huge temperature range (-30°C to 30°+) so I have 13 or 14 colours each for a 5° range
