Local Environmental Conditions
The area around this part of Brownsville is mostly built-up land, with some woodland. A nearby park adds mown lawns and planted trees to the local pollen mix. Of the trees nearby, ash and willow are the ones that matter most for allergies. Grass pollen is significant here, and pigweed contributes weed pollen.
Tree pollen peaks in early spring, when the weather warms to around 20°C and ash and willow are in full flower. Grasses take over in mid-spring, with temperatures around 25°C, and their pollen lingers into late fall. Pigweed brings a final peak from early summer into early fall. Rain is heaviest in summer, often giving short breaks from high pollen levels.
