Local Environmental Conditions
The heart of San Vicente de Baracaldo is densely built up. The damp ground beside a watercourse nearby supports trees such as poplar and alder, adding to local pollen. The leading allergenic tree nearby is oak, with alder and hazel close behind. Beyond the trees, grasses matter a great deal, and pellitory and plantain are the main weed sources.
The pollen year starts in late winter, when alder and hazel flower. Tree pollen peaks in mid-spring, when the weather warms to around 15°C and oak is in full flower. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Pellitory and plantain flower through much of the warmer half of the year.
