Navigating Travel During Haze and Wildfire Smoke Events
Wildfire smoke contains fine particulate matter that can irritate the respiratory system and cause burning eyes. When visiting affected US cities, use the official AirNow.gov portal to verify hourly pollution ratings before planning walks. If outdoor conditions are poor, explore indoor cultural sites, such as the Art Institute of Chicago or NYC museums.
