Ulmus parvifolia
Very low today, mostly grass pollen.
Last updated July 20, 2026
Pollen levels across Koreatown are quiet today. Tree pollen is essentially absent, and grass pollen is registering only very lightly. For most people, this should be an easy day outdoors, with little to no irritation expected even for those who are typically sensitive to grass. Looking ahead, this calm pattern is expected to hold steady over the next several days, with grass staying at a similarly low, mild level and tree pollen remaining absent. This fits with the season: local trees such as oak, jacaranda, ficus, and lagerstroemia have largely finished their heavier pollen release for the year, and grass typically lingers at low background levels through the summer before ragweed and other weeds become more relevant later in the season.
