Planning your day in London
Check both ends of a London journey rather than treating one central reading as a result for every borough. A model estimate and a monitor reading answer different questions; the panels below identify which is available.
Start with central London, your borough, your walking or cycling route. Choose the actual point on the map to compare it with the city-centre location used on this page.
What should you do when pollution rises?
Read the health advice for the index and country you are using. On poorer-air days, consider shortening or rescheduling strenuous outdoor activity. Children and people with heart or lung conditions may need extra care.
- Understand AQI and concentration
- Running when air quality changes
- Walking with children

Sources and limits
This page shows readings from nearby monitoring stations of public and community networks, such as Sensor.Community, WAQI, OpenAQ, PurpleAir and Syngeos, and in Poland the official GIOŚ network. When no station is nearby, it shows a Copernicus model estimate. Measurements and model values are different kinds of information; a missing or old reading is not evidence of clean air.
