We monitor fog in Krakow and visibility at Krakow Airport (Krakow-Balice) to tell you whether flights can depart and land on schedule.
Current Weather Conditions: Fog and Visibility
Morning and evening inversions often create fog in Krakow, and the airport’s bowl-shaped setting can trap humid air. When visibility at Krakow Airport drops below 400–550 m, controllers may slow departures and arrivals or enable low-visibility procedures.
Reading the numbers
- Visibility above 1,000 m typically allows standard operations.
- 400–1,000 m triggers capacity cuts and sequencing delays during peak hours.
- Below 400 m often requires LVP and can push crews toward alternates.
Why Fog Often Forms in Krakow
Fog at Krakow-Balice is common because cold, calm nights let moist air from the Vistula valley settle over the field. Autumn and winter bring frequent radiation fog, and advection fog appears when mild, moist air moves over the cooler ground near the airport.
Typical triggers
- Radiation fog after clear, windless nights with high humidity.
- Advection fog when moist air moves in from the west and cools over the valley.
- Post-rain cooling in the evening, keeping low-level moisture in place.
How Fog Impacts Flights and Airport Operations
Dense fog tightens approach minima and slows the arrival/departure rate. If RVR falls below local minima, crews may hold for improvement or divert to airports with better conditions. Knowing real-time visibility at Krakow Airport and ILS availability helps predict whether departures and arrivals will proceed.
What passengers should watch
- RVR trends in METAR/SPECI reports and any mention of LVP activation.
- Airline and airport updates on delays, cancellations, or diversions.
- Alternative plans in case fog persists through your departure window.
