Pollen and Hay Fever in Los Angeles, CA
In Los Angeles, California, the allure of warm weather and coastal breezes is tempered by the reality of pollen allergies for many residents. Despite its coastal climate, which generally results in lower pollen counts than other states with similar weather, there's no shortage of seasonal allergies in the city of angels. In fact, these allergies are primarily triggered by pollen from grasses, trees, and weeds.
Understanding the rhythm of allergy seasons in Los Angeles can be helpful. The city's milder winter means that allergy season starts earlier than in many other places, often kicking off in late January. However, thanks to California's climate, the season can be somewhat less intense for allergy sufferers.
Pollen allergies in the city have their own seasonal cadence. Spring allergies are usually a result of tree pollen, while grass pollen is the main culprit in the summer. Come fall, pollen from weeds tends to dominate the allergy landscape.
There are certain times of the year when pollen counts peak, and those with seasonal allergies may want to take extra precautions. In Los Angeles, April, May, and September are typically the months when seasonal allergies are at their peak. It's during these months that pollen counts are high, especially during the day.
By late October or November, the allergy season usually comes to an end, giving residents a break from their seasonal allergies. However, it's worth noting that indoor allergens can still cause issues for many, even when outdoor allergens are less of a concern.
Los Angeles is home to a variety of plants that can contribute to pollen allergies. Among the most common allergens are several types of grass, including Bermuda grass, Bent grass, Timothy grass, Orchard grass, and Bluegrass. Other culprits include weeds like Ragweed, Saltbush, Russian thistle, and Sagebrush. Certain trees, such as Cypress, Willow, Oak, Maple, Walnut, and Ash, also contribute to the pollen count in the city.
Although allergies can be a bother, understanding the types of pollen and their seasons can help residents navigate life in Los Angeles more comfortably, even during peak allergy season.
