About Pollen in Kensington and Chelsea

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.

The pollen count in Kensington and Chelsea today is moderate, driven mainly by Perennial Ryegrass.
