Local Environmental Conditions
Hamilton Golf & Country Club is surrounded mainly by woodland, which covers around 55% of the nearby area, with a good deal of open grassland and some built-up land. Running water nearby means riverside trees such as willow, poplar and alder are part of the local pollen picture. Common allergenic trees nearby include maple, oak and birch. Grass pollen is significant here, and ragweed and plantain contribute weed pollen.
Tree pollen peaks in mid-spring, when the weather warms to around 10°C and maple, oak and birch are in full flower. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. The season closes with ragweed and plantain from late summer into mid-fall. Rain is heaviest in summer, often giving short breaks from high pollen levels.
