Pollen Count & Forecast for Windsor, Windsor and Maidenhead
About Pollen in Windsor
Windsor’s spring allergy profile peaks March-May with high tree pollen; Birch, Oak, and Hornbeam dominate from Windsor Great Park and Home Park’s mature woodlands. Summer transitions to significant grass pollen (May-July), originating from the extensive riverside meadows and Thames embankments.
The Thames Valley’s sheltered topography and enclosed green spaces, like Alexandra Gardens, can concentrate pollen, intensifying local airborne allergen exposure. Autumn (September-November) brings elevated mould spore counts, driven by decomposing leaf litter within forested areas and persistent riverside humidity.
