Hay fever in Birmingham
How Birmingham's worst month for each type compares with the other 18 UK and Ireland cities on Respira, on the same 2023–2025 model average:
- Grass: peaks in June, 4th highest of 19.
- Birch: peaks in April, 2nd highest of 19.
- Alder: peaks in March, 9th highest of 19.
- Mugwort: peaks in July, 2nd highest of 19.
Across Britain and Ireland, grass pollen is the main trigger of hay fever, from late spring into summer. Tree pollen (alder, then birch) comes first, and mugwort follows in late summer where it grows. Ragweed, which dominates late summer in parts of central Europe, barely registers here.

Where does the pollen data for Birmingham come from?
Today's levels, the forecast and the calendar on this page all come from the Copernicus Atmosphere Monitoring Service (CAMS) model, through Open-Meteo. It is a model of what is in the air at Birmingham's coordinates, not a count from a pollen trap, so it can differ from a station reading. The page is rebuilt every morning and shows when its data was last updated.
