Chinese evergreen elm
Ulmus parvifolia
Low today, mostly weed pollen.
Last updated September 30, 2026
Weed pollen is the main source of irritation in Universal City today, sitting at a moderate level that could be noticeable for anyone with sensitivities. Grass remains very low and largely a non-issue, while tree pollen is absent altogether, so most of the day's discomfort, if any, will trace back to weeds rather than trees or grasses. Looking ahead, weed pollen is expected to ease slightly over the next few days but should stay at a moderate level worth being mindful of. Grass will continue at a very low, steady level, and tree pollen should remain quiet throughout the stretch. This pattern fits the season well: late September falls within the typical window for weed pollen, including ragweed, to be at its most active, while local trees like pine, juniper, and eucalyptus are well past their spring peak and contributing little right now.
