Pollen Count & Forecast for Kensington and Chelsea, Hammersmith and Fulham

Kensington and Chelsea, Hammersmith and Fulham experience peak spring tree pollen (March-May) from Birch, Oak, and Plane, sourced heavily from Hyde Park, Kensington Gardens, Holland Park, and extensive street plantings; summer brings dominant Grass pollen (May-July) from Thames-side meadows, including Bishop’s Park and Hurlingham Park, and widespread urban green spaces.

The urban heat island effect can prolong pollen seasons; built-up areas may trap higher concentrations of airborne allergens. Late autumn/winter sees elevated Mould spore levels, originating from damp leaf litter decomposition in local parks and along the humid Thames riverbanks.
