Air Quality in Poland 2026: 12 Essential Smog Facts for Expats
Air Quality in Poland has once again become a top concern in early 2026, especially for expats living in Kraków, Warsaw, Rzeszów and other major cities. If you moved to Poland for work, study or family life, you’ve probably already heard about “smog season.” However, understanding what the data actually means — and how it affects your daily routine — is crucial for protecting your health.
In January 2026, the situation escalated to the point where the Government Centre for Security (RCB) sent emergency SMS alerts to residents in eight voivodeships due to dangerously high pollution levels. Therefore, this guide breaks down the latest data, explains health risks, and provides clear, practical advice tailored specifically to expats.
January 2026 Smog Crisis: What Happened?
On 22 January 2026, millions of residents received official RCB warning messages about hazardous air pollution. According to reports cited by environmental organizations, particulate matter levels reached values unseen in recent years.
Most importantly, in some cities PM10 concentrations exceeded seasonal limits more than sixfold. As a result, public health advocates described the episode as a temporary public health crisis.
Cities Hit the Hardest
- Rzeszów – identified as the main hotspot
- Kraków
- Katowice
- Gdańsk
- Łomża
In response, Rzeszów introduced free public transport to reduce traffic emissions during peak pollution days. However, experts emphasize that domestic coal heating remains the primary driver of winter smog.

Kraków 2026 Data: What the Numbers Really Show
Kraków has long been associated with smog discussions. Nevertheless, the 2026 data shows a more nuanced picture.
First 75 Days of 2026 (January–March)
Between 1 January and 18 March 2026 (75 days total):
- 19% of days met WHO safe air standards
- 49% of days had moderately polluted air
- 27% of days had polluted air
- 5% of days had very polluted air
Therefore, roughly four out of five days in early 2026 exceeded WHO recommendations. You can compare WHO global guidelines at Source.
Highest AQI Days in Kraków (2026)
| Date | AQI | Category |
|---|---|---|
| 21 January | 182 | Unhealthy |
| 22 January | 178 | Unhealthy |
| 23 January | 176 | Unhealthy |
| 5 February | 127 | Unhealthy for sensitive groups |
| 5 March | 100 | Moderate |
In contrast to 2025 and 2023, Kraków ranked third in highest AQI values compared to the last five years as of mid-March 2026 — which actually signals gradual improvement.
What Does AQI Mean for Expats?
The Air Quality Index (AQI) translates complex pollution data into a simple numerical scale. According to Source, AQI values are grouped into categories:
- 0–50: Good
- 51–100: Moderate
- 101–150: Unhealthy for sensitive groups
- 151–200: Unhealthy
- 201+: Very unhealthy
Therefore, when Kraków recorded AQI 182 in January, outdoor activity posed risks even for healthy adults.
Main Pollutants in Polish Smog
Understanding the components behind Air Quality in Poland helps you make informed health decisions.
PM10
Particles up to 10 micrometers in diameter. These irritate eyes, nose and throat. Furthermore, they aggravate bronchitis and asthma.
PM2.5
Much finer particles (2.5 micrometers or smaller). Because they penetrate deep into the lungs and bloodstream, they are linked to cardiovascular disease and long-term respiratory damage.
Toxic Compounds
In addition, winter smog may contain carcinogenic metals and organic compounds resulting from coal combustion.
European air quality standards are regulated at EU level. You can explore the legal framework at Source.
Who Is Most at Risk?
Although everyone is affected, certain groups face higher risks:
- Children
- Elderly people
- Asthma sufferers
- People with cardiovascular conditions
Most importantly, expat families with young children should pay special attention to school commute times during high AQI days.
Why Does Smog Happen in Poland?
The primary cause remains coal-based domestic heating systems. While traffic contributes, experts consistently identify household furnaces (“kopciuchy”) as the dominant winter source.
However, geography also plays a role. For example, Kraków lies in a basin surrounded by hills, which limits air circulation during cold, windless days. As a result, pollutants accumulate quickly.
Warsaw vs Kraków: Is the Capital Better?
Warsaw typically experiences slightly better winter averages than Kraków. Nevertheless, temperature inversions and suburban coal heating can still trigger poor AQI days.
In contrast, coastal cities like Gdańsk often benefit from stronger winds, which disperse pollutants faster. Therefore, location within Poland significantly impacts your exposure.
How to Protect Yourself During Smog Season
- Check AQI daily. Make it part of your morning routine.
- Limit outdoor exercise when AQI exceeds 150.
- Use HEPA air purifiers indoors.
- Wear certified masks (FFP2/FFP3) on extreme days.
- Ventilate strategically — air out your flat when AQI temporarily drops.
Furthermore, many modern apartments now advertise built-in air filtration systems — something worth considering when renting.
Government and Local Government Actions
Polish authorities continue implementing anti-smog resolutions at regional level. In addition, subsidies for replacing coal furnaces are available in many regions.
During peak episodes, some cities:
- Offer free public transport
- Increase inspections of heating systems
- Issue public SMS warnings

Is Air Quality in Poland Improving Long-Term?
Despite dramatic January headlines, long-term data suggests gradual improvement compared to a decade ago. Cleaner heating regulations in cities like Kraków have already reduced average particulate levels.
However, progress remains uneven between regions. Therefore, expats considering relocation should compare voivodeship-level statistics before choosing a city.

Historically Kraków and parts of Silesia rank high, but in January 2026 Rzeszów recorded some of the highest levels.
3. When is smog season in Poland?
Typically from November to March, when coal heating and temperature inversions are common.
4. Should I buy an air purifier in Poland?
Yes, especially if you live in southern Poland. A HEPA-certified purifier can dramatically reduce indoor PM2.5 levels.
