How to read this page

The live cards show city-level AQI from Open-Meteo at specific coordinates, led by Saint Helier. The national PM2.5 chart shows annual population-weighted exposure for Jersey. These are related, but they are not the same measurement.

Sources and limits

Live AQI, PM2.5, PM10, UV, and pollen context come from Open-Meteo's air-quality API. National PM2.5 exposure comes from the World Bank indicator EN.ATM.PM25.MC.M3. Local official alerts should take priority during smoke, dust, or pollution events.

Air quality FAQ

No. Live AQI is local, so this page shows city readings for Jersey, starting with Saint Helier. The national PM2.5 chart is the country-level long-term indicator.

National PM2.5 is the population-weighted annual mean exposure to fine particulate matter. It is useful for country comparisons, but it is not a live forecast.

The live city AQI endpoint is cached briefly, usually around 10 minutes, to keep readings fresh while reducing upstream load.

Air pollution is highly local. Traffic, industry, wildfire smoke, dust, wind, rain, altitude, and urban layout can make one city in Jersey much cleaner or dirtier than another on the same day.
