Local Environmental Conditions
This site in Country Club, California, is surrounded mainly by farmland, with some open grassland. Close to running water, riverside vegetation contributes to what is in the air. Around here, open grassland and farmland add grass and weed pollen. Field margins, fallow strips and pasture around the farmland add further grass and weed pollen.
Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. Weeds on open ground add a smaller late peak from early summer into early fall. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen. Day to day, sunshine and wind lift the counts, while a spell of rain can bring them down sharply.
