Local Environmental Conditions
This site in East Porterville is surrounded mainly by open grassland, with some woodland and built-up land. A nearby park adds mown lawns and planted trees to the local pollen mix. Of the trees nearby, oak is the one that matters most for allergies. Grasses are also a significant pollen source here.
Oak leads the season in mid-spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Then come the grasses, strongest in late spring and fading by early fall. Weeds on open ground add a smaller late peak from early summer into early fall. Spring is the wettest time of year, and heavy showers can bring short breaks in pollen.
