Pollen Count & Forecast for Southend-on-Sea, Castle Point

Southend-on-Sea’s spring pollen season commences with Birch and Oak (March-May), primarily from Priory Park, Southchurch Park, and mature urban canopy; this is succeeded by pervasive grass pollen (May-July), prevalent across coastal verges and estuarial meadows adjacent to the Thames Estuary.

Southend’s distinct urban-coastal geography can concentrate airborne allergens, with sea breezes variably dispersing or trapping local pollen; autumn-winter mould spores (October-February) proliferate due to damp leaf decomposition and elevated coastal humidity, particularly in shaded, poorly ventilated areas.
