Local Environmental Conditions
Around 50% of the area near this location in Fairfield is open grassland, with some woodland and farmland. Lawns and planted trees in a nearby park add to local grass and tree pollen. Allergenic trees nearby include maple and poplar. Beyond the trees, grasses matter a great deal, and ragweed is the main weed source.
Maple and poplar lead the season in mid-spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Ragweed brings a final peak from late summer into mid-fall. Rain is heaviest in summer, often giving short breaks from high pollen levels. By late fall, pollen levels are low again.
