Flight Operations Disrupted in Delhi and Mumbai Due to Severe Weather: Travel Advisory Issued

Heavy monsoon rains and strong winds have led to significant disruptions in flight operations across India’s chief airports, particularly in Delhi (Indira Gandhi International Airport) and Mumbai (Chhatrapati Shivaji Maharaj International Airport). According to reports, this severe weather has resulted in 15 flight diversions from Delhi, 5 diversions for Mumbai-bound flights, and an additional 13 inbound diversions at Mumbai. Notably, flights have faced widespread delays, with nearly 90% of scheduled departures affected during peak operational hours. In particular, rainfall in Mumbai has reached over 200 mm within just a 12-hour window, compounded by wind speeds reaching up to 42 knots. These conditions have severely hampered visibility and prompted airlines, including Air India and IndiGo, to reroute flights through alternate airports such as Jaipur, Lucknow, Surat, Ahmedabad, and Goa (Mopa). During this period, delays have averaged around 65 minutes per flight.

This article delves into the factors leading to these disruptions, the extent of the impact on flights, the response from airlines, and how India’s aviation infrastructure is adapting to these challenging weather conditions.

Widespread Disruption Across India’s Major Flight Hubs

The turbulent weather has drastically affected operations along India’s busiest air route, linking Delhi and Mumbai. The intense monsoon conditions have brought heavy rain, thunderstorms, and high gusts of wind that exceed safe operating parameters for aircraft.

Official accounts from airport authorities and meteorological reports indicate that the disruption has led to:

• 15 flights diverted from Delhi (5 July 2026) to alternate airports like Jaipur and Lucknow.
• 5 flights en route to Mumbai diverted (5–6 July 2026).
• 13 additional inbound flights diverted while operating in Mumbai’s airspace (various airlines).
• 4 IndiGo flights cancelled amid peak disruption.
• Approximately 90% of departures delayed at Mumbai airport during critical hours.
• Average delay duration: about 65 minutes for Mumbai flights.

The root cause of these delays has been attributed to the severe weather conditions classified as a red alert by the Indian Meteorological Department (IMD), which reported rain accumulation exceeding 200 mm in a span of 12 hours in Mumbai. These hazardous conditions have significantly destabilized runways and reduced aviation visibility to levels below the regulatory minimums.
