Pollen and Hay Fever in Corona, CA
In Corona, California, people often experience pollen allergies, commonly known as hay fever, due to various types of pollens present in different seasons. The local climate and vegetation significantly influence the types of pollens and their peak times.
During the spring season, the most prevalent allergens come from trees. In Southern California, including Corona, the most common tree pollens include ash, olive, oak, sycamore, walnut, eucalyptus, and mulberry. In addition to these, cypress, willow, and juniper tree pollens are also quite common in nearby regions such as San Bernardino and Riverside, which could impact Corona residents as well.
As we move into the summer season, the primary culprits shift from trees to grasses. Southern Californians often contend with oat and Bermuda grasses, ryegrass, and bluegrass. Moreover, other types of grasses such as bent, timothy, orchard, and fescue are also present in surrounding areas, contributing to the overall pollen load.
When fall arrives, weeds become the dominant allergens. Sagebrush, Russian thistle, and pigweed are the biggest offenders in Southern California. In addition to these, the Corona area also sees allergens from ragweed, saltbush, and amaranth.
Winter usually provides some respite from seasonal allergies due to a decrease in outdoor pollens. However, indoor allergens can still be an issue during these cooler months.
Understanding the types of pollens present in each season in Corona, California, can help residents anticipate and recognize their allergy symptoms. While this information doesn't provide solutions or treatments, it does offer a roadmap for navigating the shifting landscape of pollen allergies throughout the year.
