About pollen in Chino

Weed pollen is the most active type in Chino today, though overall levels remain low. Grass is barely present, and tree pollen is absent entirely. Most people should move through the day without much irritation, though those especially sensitive to weeds may notice mild effects. Looking ahead, this pattern is expected to hold steady over the next several days, with weed and grass pollen staying in the low range and tree pollen remaining quiet. This fits the season well: autumn in Southern California typically brings a tail end of weed activity, such as sagebrush or ragweed, while oaks, sycamores, and other local trees stay dormant until their spring release. For now, pollen exposure in Chino should remain manageable for most residents.
