Used to be so much better before the acquisition, but I agree, they were wonderful at it for a while and some of the UI remains.

Agree. Weatherspark is great too — https://weatherspark.com/map?pageType=4&yearNumber=2025&ids=...

Each of those icons is a full year of weather data. Left to right is Jan to Dec. Bottom to top is the hours of the day. The pixel color tells you cold vs hot.
