Pollution Band: Low

Details

With a high pressure system established just to the west of the UK, largely fine and settled conditions are expected during Tuesday and Wednesday. Winds on both days will be from the Atlantic and, as such, will carry very little by way of imported pollution. A steady breeze is expected throughout Tuesday and this should give good dispersion of local emissions. Although wind speeds will be lighter on Wednesday, there should still be enough air movement to keep air pollution levels within the 'Low' banding.

Air pollution is expected to remain 'Low' for the following pollutants during the forecast period:
Nitrogen Dioxide
Ozone
PM10 Particulates
PM2.5 Particulates
Sulphur Dioxide

  • Step 2: If you may be at-risk, and are planning strenuous activity outdoors, check the air pollution forecast.
  • Step 3: Use the health messages corresponding to the highest forecast level of pollution as a guide.
