• Today : Air pollution levels are expected to be mostly Low. However, isolated pockets of Moderate pollution may develop across parts of Wales due to light winds and warm, sunny conditions.
  • Tomorrow : Some similar conditions on Thursday, allowing further areas of Moderate pollution to develop through parts of Wales and perhaps central southern England. Otherwise air pollution levels will be Low.
  • Outlook : Air pollution levels will most likely remain Moderate but increasingly widespread during this period, at least away from the east coast, due to warm, dry and settled conditions persisting over the country.
