How we calculate the score
For mountain destinations, we calculate two scores per month — skiing and hiking — and display the higher of the two.
- 40% snow cover (slope T° corrected by lapse rate -3.6°F/1000ft)
- 40% winter thermal comfort (23–41°F optimal)
- 20% sunshine
- Off-season penalty: ×0.70 adjacent months · ×0.35 outside season
- 40% temperature (50–72°F optimal)
- 40% rain (frequency + daily intensity)
- 20% sunshine
