What drives air pollution in Havana

The dominant pollution sources affecting Cuba cities like Havana are:

• vehicle emissions
• industrial activity
• residential energy use
• regional dust or biomass burning
• construction and dust

Seasonal pattern

Air quality varies seasonally based on local meteorology, fuel use, and regional fire/dust events.

Geography and meteorology

Havana sits at approximately 23.13° latitude, -82.38° longitude. Local geography (basins, coastal exposure, elevation) heavily influences pollution accumulation patterns.

Health implications

Most people will rarely face health risk from air quality alone. Sensitive individuals should still check during pollution events. The most-studied pollutant for population health is fine particulate matter (PM2.5). Exposure is linked to cardiovascular disease, respiratory illness, and increased mortality. Children, the elderly, and people with respiratory or cardiac conditions face elevated risk.

Other pollutants commonly elevated in urban areas:

• Ozone (O3) - peaks on hot, sunny afternoons
• Nitrogen dioxide (NO2) - traffic-correlated, peaks at rush hours
• PM10 - includes road dust and coarse particles

Policy and trajectory

Air quality policies vary widely across jurisdictions. Coverage and enforcement levels affect outcomes more than nominal standards.

Practical guidance for residents and visitors

1. Check the AQI before outdoor exercise. If readings exceed 100, sensitive groups should reduce intensity. Above 150, everyone should consider shifting indoors.
2. Wear an N95 or KN95 during peaks. Cloth masks do not filter PM2.5.
3. Run a HEPA air purifier in bedrooms. Indoor levels typically track 50-70% of outdoor levels in unfiltered homes - see our air purifier buyer's guide.
4. Use mechanical ventilation with HEPA filtration when AQI is high; avoid simply opening windows.
