Pollution Band: Low

Details

Whilst remaining warm the bank holiday weekend is expected to have lower temperatures than this week.

On Saturday there is a small chance of some 'moderate' ozone particularly in the southeast suburbs as air comes in from the near continent and reacts on the warmest of the days.

The rest of the weekend will have varying cloud levels and changing wind directions that will bring air mainly from other parts of the UK, with possible recirculation of London emissions overnight Sunday into Monday.

With holiday traffic some roadside locations may reach 'moderate' for nitrogen dioxide, with historically Sunday and Monday evenings being the worst as people return to London.

Generally air pollution is expected to remain 'Low' for the following pollutants:

Ozone
Nitrogen Dioxide
PM10 Particulate
PM2.5 Particulate
Sulphur Dioxide








This forecast is intended to provide information on expected pollution levels in areas of significant public exposure. It may not apply in very specific locations close to unusually strong or short-lived local sources of pollution.
