1966 Temperature Blanket

Hi everyone,
my sister is celebrating her 60th birthday at the end of the year. I had the idea to knit her a temperature blanket for her birth year, 1966. Does anyone have any tips on where I could find the temperature data?
Thanks in advance, have a wonderful holiday (despite the rainy weather), and best regards,
Monika

Could you maybe check with the weather service?

Hallo such mal bei Google: kachelmannwetter archiv
Da habe ich meine Daten her.

Hi Monika,
I’d start with AI: Ask it your question, and it’ll either answer it or give you some links.
Among other things, this site was recommended to me:
weatherspark.com
There, you can search by date and location, even for past data.
Best, Inna

Hi Inna, thank you so much for the tip about wheatherspark.com. I found exactly what I was looking for there. Now I can get to work.
Best wishes, Monika 

You’re welcome, and good luck!
