Chinese evergreen elm
Ulmus parvifolia
Low today, mostly weed pollen.
Last updated September 29, 2026
Weed pollen is the main presence in Hollywood today, though it remains at a low level that most people won't notice. Grass is barely registering, sitting at a very low level, while tree pollen is absent altogether. Overall, this adds up to a mild day for allergy sufferers, with little reason to expect significant irritation. Looking ahead, this pattern is expected to hold steady through the next several days: weed pollen staying low, grass at a very low level, and trees remaining quiet. This lines up with the seasonal calendar, as local trees such as Ficus, Washingtonia, and Callistemon typically release their pollen in spring rather than fall, so their dormancy now is expected. The modest weed presence is more in keeping with late-summer and autumn patterns, and it's likely to be the main factor influencing air quality for allergy purposes in the coming days.
