Delhi’s deteriorating air quality this winter is impacting international tourism. Rising pollution has led several countries to issue travel advisories and cause some tourists to rethink or alter their travel plans.
The Air Quality Index (AQI) in Delhi and the surrounding National Capital Region has stayed in the “very poor” to “severe” range. The heavy pollution and hazardous air conditions pose health risks to both tourists and residents. Fog and smog have also disrupted travel, causing flight delays and reduced visibility at Indira Gandhi International Airport.
Several foreign governments, including those of Singapore, the United Kingdom and Canada, have issued health advisories urging their citizens to be cautious about visiting Delhi due to the poor air quality. These advisories highlight risks for people with respiratory conditions, older adults and children.
According to travel agencies and tour operators, some tourists are cutting short their vacations in Delhi or opting for other locations with better air, while others are completely cancelling their scheduled trips. The trend is a reflection of rising worry that during the busiest winter tourism season, severe air conditions may make outdoor sightseeing and cultural experiences less appealing.
The deterioration in air quality comes as the city enters its typical winter smog season, driven by factors such as low wind speeds, temperature inversions and emissions trapped near the surface. These conditions have compounded the problem, keeping pollution levels persistently high and affecting daily life as well as tourism.
