Pollen Count & Forecast for Stockton-on-Tees, Stockton-on-Tees

Stockton-on-Tees experiences dominant spring tree pollen from late March through May, primarily Birch and Oak originating from Ropner Park, Preston Park, and wider urban green spaces; subsequently, high grass pollen levels characterise May to July, prevalent along the River Tees’ extensive banks and numerous playing fields. The Tees Valley’s urbanisation can concentrate pollen, with elevated levels often persisting within the built environment; late-season mould spores are significant from late August through November, stemming from decomposing leaf litter in parks and damp, shaded urban fringes.
