Current forecast information
General population
Enjoy your usual outdoor activities.
At-risk individuals
Adults and children with lung problems, and adults with heart problems, who experience symptoms, should consider reducing strenuous physical activity, particularly outdoors.
Cold, very still weather is forecast to continue due to a high pressure system over the United Kingdom.
Primary pollutants emitted during evening domestic wood burning in residential areas during this cold snap, are likely to persist into the early hours of each morning.
A further build-up of pollution is then expected in the morning and evening rush hour periods as working weekday emissions and re-suspension from dry dirty roads are poorly dispersed, resulting in 'Moderate' levels of PM10 and PM2.5 particulate. The worst pollution is expected close to busy roads in central and inner London, with particulate levels possibly reaching the 'Moderate' banding.
'Moderate' levels of nitrogen dioxide are also slightly possible near to congested roads during the morning and evening rush hour periods.
Air pollution is expected to remain 'Low' throughout the forecast period for the following pollutants:
Ozone
Sulphur Dioxide

Particulate concentrations may also rise during the evenings due to domestic wood burning. However, pollution levels are expected to remain in the 'Low' banding as there should be sufficient breeze to disperse emissions.
