Local Environmental Conditions
The area around this site in Old Malibu is mostly open grassland, with a good deal of scrubland and some woodland. Of the allergenic trees nearby, oak matters most, while plane tree also contributes. Beyond the trees, grasses matter a great deal, and mugwort and ragweed are the main weed sources. Mugwort is unusually common here compared with most other locations, making it a particularly important local pollen source.
Tree pollen peaks in early spring, when the weather warms to around 15°C and oak and plane tree are in full flower. Then come the grasses, strongest in late spring and fading by mid-fall. The most intense period comes through summer, when mugwort and ragweed are in flower. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen.
