Very low today, mostly weed pollen.
Last updated August 15, 2026
Pollen levels around Glendale are quiet today. Tree pollen is absent, and weeds are barely registering, so most people should be able to go about their day without much irritation. Overall, this is about as calm as air quality for allergies gets. Looking ahead, tree pollen is expected to stay silent over the next several days, which lines up with the season, as local varieties like Magnolia, Eucalyptus, Acacia, Washingtonia, and Liquidambar are past their spring release and largely dormant now. Weed pollen, on the other hand, is expected to inch upward through the week, moving from very low to a mild but more noticeable level by the weekend. This gradual rise fits the late-summer pattern, when weeds tend to become the main source of outdoor pollen as tree and grass seasons wind down.
