Sources & methodology

Climate comfort helps estimate how practical daily life may feel across the year, especially for heat, humidity, cold, and seasonal constraints.

Seasonal timing, health conditions, air conditioning, air quality, and elevation can change the lived experience.

Partnerships never affect rankings, scores, methodology, or inclusion.
