Ulmus parvifolia
Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main player in Koreatown today, sitting at a Low level (2) and leading the overall index, which also reads Low. Tree pollen has dropped to Very Low (1), so the city's familiar allergenic trees — Ficus, Washingtonia, Cinnamomum, Eugenia, and Pittosporum — are contributing little at the moment. The five-day forecast holds grass steady at Low (2) right through the period, with no notable rise or fall expected. That flat pattern fits the season, as late spring's grass activity tends to linger into early summer while the spring tree peak winds down. Weed pollen data isn't available right now, so it isn't reflected in today's reading.
