Air pollution alerts
An alert is raised when air pollution is expected to be higher than usual (moderate, high or very high on the Daily Air Quality Index).
No alert is raised for low air pollution, so you won’t get an alert on these days.
The forecasts go up to 3 days ahead, so you can plan ahead in terms of clothing, medication, routes and outdoor activities.
Follow the health guidance to reduce the effects of air pollution, pollen, extreme weather, and UV.
