Pollen and Hay Fever in West Covina, CA
In the picturesque city of West Covina, California, the blooming flowers and lush greenery are not just a treat for the eyes, but sometimes a challenge for the sinuses. The region is a hotspot for pollen allergies, commonly referred to as hay fever.
One of the culprits behind the itchy eyes and sneezes is tree pollen. In West Covina, trees such as oaks, pines, and olive trees begin to release pollen as early as late winter and continue through the spring. This is the time when residents may notice a fine dusting of yellow on their cars and sidewalks, which is actually pollen!,As spring turns into summer, grass pollen takes center stage. Bermuda, Kentucky bluegrass, and ryegrasses are common in Southern California, and they release pollen that can cause allergic reactions. If you’re an outdoor enthusiast, be mindful of grassy areas during the early summer months.
Towards the end of summer and beginning of fall, the main source of pollen shifts to weeds. In West Covina, ragweed is a common weed that releases copious amounts of pollen into the air. Other weeds such as sagebrush and tumbleweed also contribute to the pollen count.
The varying climate in West Covina means that different types of pollen are in the air at different times of the year. The mild winters allow for early tree pollen, while the warm summers support grass growth. The transition into fall brings weed pollen to the forefront.
Being aware of the pollen seasons in West Covina is the first step in understanding what triggers your allergies. While the natural beauty of the city is undeniable, the pollen from trees, grasses, and weeds might cause some residents to keep their tissues handy.
