Comfort Index
?
About the model
- Comfort Index is a 0-100 score that estimates how comfortable it will feel outside. Higher scores generally mean better conditions and more usable outdoor time.
- The score factors in heat, cold, humidity, wind, cloud cover, rain, thunder risk, air quality, and how consistent conditions stay throughout the day.
- This archive refreshes about every 6 hours: 2:20 AM, 8:20 AM, 2:20 PM, and 8:20 PM ET.
