Southall sits in Greater London and takes its pollen pattern from the Greater London forecast region. Around 78,300 people live here. Hay fever sufferers should track all three pollen types from March through August.
Tree pollen here is dominated by London plane, oak and lime, with grass led by ryegrass and cocksfoot and weeds by nettle and mugwort.
Tree pollen typically peaks in late March to early May. Grass counts are highest from late May into early July. Mature urban canopy with high plane and lime cover keeps the tree count active well into May.
