Flying out of Balice tomorrow morning, or picking someone up? We check the weather forecast for Krakow-Balice Airport and rate whether the coming night and morning favour fog in Krakow. The rating refreshes several times an hour.
Fog risk for the coming night

Fog risk: low
The forecast shows no conditions favouring fog at Balice.

In the morning, check whether fog actually formed at Balice — that page shows readings from the airport weather station, not a forecast — and the live flight status for Krakow.
What fog can mean for early flights
Fog does not close the airport straight away. When visibility drops, Balice switches to low visibility procedures (LVP): aircraft land and take off with larger gaps, so fewer flights are handled per hour. The first noticeable effect is usually delays, especially in the morning departure wave.
Diversions to Katowice and other alternates only happen when visibility along the runway falls below landing minima. What those values are and what they depend on is explained in our article on required visibility for landing in Krakow; diversions themselves are covered in fog and flight diversions in Krakow.
How we rate the fog risk
We use a model weather forecast for Balice in 3-hour steps and, for each time, look for the signals that precede radiation fog — the most common type of fog at the airport:
- Humidity close to 100%, meaning the air is almost saturated with water vapour.
- Temperature close to the dew point — once the gap shrinks to 1–2°, water vapour starts condensing in the air.
- Light wind — in calm conditions cold, moist air settles near the ground; stronger wind mixes it and disperses fog.
- Model visibility and weather — if the model itself forecasts fog or mist, the risk goes up. Reduced visibility in rain is not counted as fog.
These signals give a risk level: low, moderate or high. The card shows the highest level between 18:00 and 12:00 the next day, and the hours when it peaks. Before noon the card covers the current morning; from noon, the coming night.
When fog forms over Balice
The airport sits in a dip in the terrain near the Vistula valley. On clear, calm nights the ground loses heat quickly, cold and moist air collects near the surface, and fog is often thickest around and just after sunrise. This happens most often in autumn and winter, especially from November to February.

Flying tomorrow morning? What to do the evening before
- Turn on notifications in your airline's app — the airline is the first to announce a delay or a change of airport.
- In the morning, before you leave, check fog at Krakow-Balice today and Krakow-Balice flight information.
- Allow extra time to get to the airport — fog slows road traffic too.
- If you are meeting an early arrival, be ready for the aircraft to land later or in Katowice. See what happens after a diversion to Katowice.
- If your flight is cancelled or badly delayed, check your passenger rights in bad weather.
What this forecast cannot tell you
A model forecast describes conditions around the airport, not the visibility measured along the runway (RVR) that crews base their decisions on. Fog can form in patches, earlier or later than forecast, and 3-hour steps can miss a short episode. That is why we talk about risk rather than announcing disruption — your airline and the airport decide about your flight.

FAQ
Will there be fog in Krakow tomorrow morning?
This page shows the fog risk for the coming night and morning at Krakow-Balice Airport: low, moderate or high, together with the hours when it peaks.
Where does the fog forecast come from?
From the OpenWeather model forecast for Balice in 3-hour steps. We derive the risk from humidity, the temperature–dew point gap, wind and model visibility.
Does fog mean my flight will be delayed?
Not necessarily. In fog the airport runs low visibility procedures and handles fewer flights per hour, so delays are more common, but decisions about a specific flight are made by the airline and the airport.
What time is fog at Balice usually thickest?
Most often early in the morning, around sunrise, when the ground is coldest. A few hours after sunrise fog usually lifts or clears.
How often is the forecast refreshed?
The page is rebuilt about every 10 minutes. A forecast older than 6 hours is hidden and replaced with a notice that it is unavailable.
