Chinese evergreen elm
Ulmus parvifolia
Low today, mostly weed pollen.
Last updated September 29, 2026
Pollen levels in Koreatown are on the mild side today. Weeds are the most active category, sitting at a low level, while grass is barely present and tree pollen is absent altogether. Most people should get through the day without much irritation, though those who are especially sensitive to weed pollen may notice a mild effect. Looking ahead, this pattern is expected to hold steady over the next several days, with weed pollen easing slightly and grass staying at a very low, consistent level. Tree pollen should remain quiet throughout, which fits the season, since local varieties like oak, jacaranda, ficus, cinnamomum, and crape myrtle typically release most of their pollen back in spring. Overall, conditions are set to stay calm and manageable through the week.
