Pollen Count & Forecast for Halifax

Halifax’s spring allergy season (April-June) is dominated by Birch (Betula) and Maple (Acer) pollen; Birch is dense in Point Pleasant Park and Hemlock Ravine Park; Maple is common along the Northwest Arm. Spruce (Picea) and Pine (Pinus) contribute significantly from the Public Gardens. Summer (June-August) has high Grass (Poaceae) levels, originating from Shubie Park and the Sackville River banks.

Coastal fog and high humidity trap airborne particles near the Atlantic shoreline; ocean breezes move pollen inland towards the city core. Autumn and winter have high Mould (Alternaria, Cladosporium) spore counts, from damp leaf litter in the Halifax Common and wooded areas around the Bedford Basin.
