All temperature scales are arbitrary, but since our environment is full of water, one tied to the phase changes of water around the atmospheric pressure the vast majority of people experience just makes more sense.

But when it comes to weather, the boiling point of water is not a meaningful point of reference.

I suppose I’m biased since I grew up in an area where 0-100°F was roughly the actual temperature range over the course of a year. It was newsworthy when we dropped below zero or rose above 100. It was a scale everybody understood intuitively because it aligned with our lived experience.
