Local Environmental Conditions
The area around this site in Camp Pendleton South is mostly built-up land, with some open grassland. The allergenic tree mix nearby includes willow, oak and plane tree. Beyond the trees, grasses matter a great deal, and pigweed and mugwort are the main weed sources. Around here, planted trees and mown lawns are the main sources in the built-up parts.
Tree pollen peaks in late spring, when the weather warms to around 15°C and willow, oak and plane tree are in full flower. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into mid-fall. Pigweed and mugwort bring a final peak from early summer into early fall. Rain is heaviest in spring, often giving short breaks from high pollen levels.
