Rush-hour queues near the M25 are usually when readings climb the most. Haywards Heath's position in West Sussex means air quality is mostly determined by local road traffic and the compact scale of the centre. Northwesterly winds off the coast help ventilate the town centre, keeping air quality at moderate levels typical for the region.

When is air pollution at its worst in Haywards Heath?
For much of spring and autumn, things settle into a fairly unremarkable middle ground. Haywards Heath's air quality follows a familiar seasonal pattern most UK towns share. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the M25 closer to ground level. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter.
Are air quality levels in Haywards Heath based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
