This reminds me of “Temperature Blankets”. They seem pretty well known in knitting/crocheting world. Typically they’ll do a row or two of a color representing the weather for each day of the year.

My wife made one for the year 2020. It’s really neat looking at it and seeing how the weather fluctuated in and out the days and weeks. I think it would be so cool to have several for different important/notable years… but they can be so much work!
