Local Environmental Conditions
Around 74% of the area near this part of Cypress, California is built-up land, with some open grassland. The damp ground beside a stream or river nearby supports trees, shrubs and reeds, adding to local pollen. The allergenic tree mix nearby includes oak. Grasses and weeds such as plantain and pigweed round out the local mix.
Oak leads the season in mid-spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Then come the grasses, strongest in late spring and fading by early fall. Plantain and pigweed flower through much of the warmer half of the year. Rain is heaviest in winter, often giving short breaks from high pollen levels.
