Local Environmental Conditions
Around 51% of the area near this part of Angels Camp is open grassland, with a good deal of woodland. A nearby park adds mown lawns and planted trees to the local pollen mix. Allergenic trees nearby include oak. Grasses are also a significant pollen source here. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Through the seasons, tree pollen comes first, with oak in flower through spring. Grass pollen builds from mid-spring, peaks around early summer and stays noticeable until late summer. Weeds on open ground add a smaller late peak from early summer into early fall. Winters average around freezing and summers around 25°C, with most rain falling in the cooler months.
