Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in Chinatown today, sitting at a moderate level (3) while tree pollen has dropped to none. That moderate grass reading reflects the late-spring-into-early-summer window when grasses typically dominate the air. The forecast points to a modest easing ahead, with grass slipping from 3 today to 2 for the next several days. Tree pollen from the area's Linden, Styphnolobium, Elm, Zelkova, and Oak is not a factor right now, consistent with the spring tree season having largely passed. With overall pollen at moderate, expect conditions to stay steady to slightly lower in the days to come.
