About Pollen in Halifax

Halifax experiences peak spring tree pollen (Birch, Oak) March-May, originating from mature specimens within Shibden Park, People’s Park, and surrounding valley woodlands; summer sees high grass pollen counts June-July, prevalent across Calder Valley meadows and local parklands like Manor Heath Park. The city’s valley topography often traps airborne allergens, intensifying local pollen levels; late-season mould spores August-October are prevalent due to Halifax’s damp climate and decomposing leaf litter in wooded areas.

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