📅 Monthly Delay Risk
How on-time performance typically varies through the year on DEL→REP based on historical weather and operational patterns:
December-January is peak fog season in North India. Dense morning fog (especially 3 AM-10 AM) can drop visibility below the limits many aircraft and crews may operate in. Delhi airport, among the worst affected, sees long delays and cancellations during severe fog spells. Lucknow, Patna, Varanasi, Amritsar, and Kolkata are similarly impacted. Airlines use CAT-III equipped aircraft to operate during lower visibility, but delays remain common.
💡 Tip: Consider booking afternoon or evening flights (post 11 AM) in Dec-Jan: visibility typically improves by mid-morning. Keep buffer time for connections. Check flight status 2-3 hours before departure.
February sees fog frequency reduce significantly but early-morning departures can still face delays of 30-90 minutes on fog-prone days. Severity is much lower than Dec-Jan.
💡 Tip: Fog delays are typically shorter in February. Early-morning flights occasionally delayed; mid-day onwards reliable.
April-May brings sudden thunderstorms ("Kalbaishakhi") to East and North India, typically in afternoon and evening hours. Afternoon and evening flights are the most affected, with delays on stormy days at Kolkata, Bhubaneswar and Patna.
💡 Tip: Book morning flights (before 2 PM) during April-May if flying to/from East India. Check weather forecast the day before.
