Pollen: questions
When is hay fever season in the UK?
Tree pollen (alder, hazel, birch, oak) runs from late winter to May, with birch peaking in April. Grass pollen, which affects the most people, peaks from late May to July. Weed pollen such as mugwort and nettle follows from June to September.
Where do these numbers come from?
From the Copernicus Atmosphere Monitoring Service (CAMS) model, which forecasts pollen across Europe. They are model estimates rather than counts from a pollen trap, and the model does not cover every species.
Why is everything at none?
Because it is outside the pollen season. From October to January the main UK pollen types are not released in any quantity.
