Lowest fare observed daily on OSL→CCU:
📅 Monthly Delay Risk
How on-time performance typically varies through the year on OSL→CCU based on historical weather and operational patterns:
December-January is peak fog season in North India. Dense morning fog (especially 3 AM-10 AM) regularly drops visibility below the 550m minimum needed for takeoff. Delhi airport — the worst affected — sees hundreds of cancellations and 2-4 hour delays 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.
June to September is peak monsoon for most of India's west coast, south, and east. Mumbai, Goa, Kerala, and Karnataka airports see heavy rainfall-triggered delays and occasional diversions. Kolkata is hit by cyclonic systems from the Bay of Bengal. Flight cancellations spike when runways flood or cross-wind limits are exceeded. July is typically the worst month.
💡 Tip: Book refundable fares during monsoon months. Avoid tight connections — monsoon delays can cascade. Late morning flights (8-11 AM) tend to be less affected than afternoon thunderstorm window.
April-May brings sudden thunderstorms ("Kalbaisakhi") to East and North India, typically in afternoon and evening hours. Flights in 3 PM-8 PM window most affected. Delays of 45-120 minutes common on stormy days at Kolkata, Bhubaneswar, Patna.
💡 Tip: Book morning flights (before 2 PM) during April-May if flying to/from East India. Check weather forecast the day before.
Oct-Nov is cyclone season for the Bay of Bengal. Chennai, Kolkata, Bhubaneswar, Vizag can see days-long shutdowns during major cyclones. Non-cyclone days are usually fine. Risk is episodic, not constant.
💡 Tip: Monitor weather advisories when booking Oct-Nov travel to East Coast. Most days are normal — only named cyclones trigger major disruptions.
