A UK wide air quality forecast map is published daily by the Department for Environment, Food & Rural Affairs (Defra).
The Air Quality Index, or AQI, plots the predicted air pollution levels for your area on a map for today, and the next three days.
You can also search by town or postcode to see more local information.
It uses a colour coded scale of 1 to 10.
Low air pollution is between 1 and 3, Moderate between 4 and 6, High is between 7 and 9, and Very High is 10 on the scale
1-3: Enjoy your usual outdoor activities
4-6: At risk individuals consider reducing physical activity outdoors
7-9: Anyone experiencing discomfort should reduce physical activity
10: Everyone should avoid or reduce physical activity
