Local Environmental Conditions
The area around this location in Idyllwild-Pine Cove is a mix of woodland and scrubland. The key allergenic tree nearby is oak. Grasses and weeds such as mugwort round out the local mix. Around here, scrubland contributes pollen from shrubs, grasses and herbs. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Oak leads the season in mid-spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grass pollen follows, peaking in late spring and easing off by early fall. The season closes with mugwort through summer. In this dry climate, pollen can linger in the air for long spells without rain. By midwinter, as temperatures fall to around 10°C, pollen levels are low again.
