Local Environmental Conditions
The center of Buenos Aires is surrounded mainly by built-up land, which covers around 94% of the nearby area. Common allergenic trees nearby include maple, willow and mulberry. Beyond the trees, grasses matter a great deal, and pellitory and mugwort are the main weed sources. Around here, street trees, gardens and lawns supply most pollen in the built-up parts.
Maple, willow and mulberry lead the season in early spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. Pellitory and mugwort flower through much of the warmer half of the year. Rain is heaviest in fall, often giving short breaks from high pollen levels.
