About Pollen in Brighton

Brighton, Flintshire’s spring (March-May) features dominant Birch and Oak pollen, originating from local green spaces and surrounding woodland edges; summer (May-July) yields high Grass pollen from nearby meadows and River Alyn banks. Local topography creates pollen hotbeds, concentrating airborne allergens. Late autumn to winter sees prevalent Mould spores, exacerbated by damp conditions and decaying organic matter in shaded areas and adjacent woodlands.

The pollen count in Brighton today is moderate, driven mainly by Mugwort.
